President Donald Trump signed an executive order Wednesday directing government agencies to “eliminate or expedite” environmental reviews for commercial launch and reentry licenses.

The Federal Aviation Administration (FAA), part of the Department of Transportation (DOT), grants licenses for commercial launch and reentry operations. The FAA is charged with ensuring launch and reentries comply with environmental laws, comport with US national interests, and don’t endanger the public.

The drive toward deregulation will be welcome news for companies like SpaceX, led by onetime Trump ally Elon Musk; SpaceX conducts nearly all of the commercial launches and reentries licensed by the FAA.

Deregulation time

Trump ordered Transportation Secretary Sean Duffy, who also serves as the acting administrator of NASA, to “use all available authorities to eliminate or expedite… environmental reviews for… launch and reentry licenses and permits.” In the order signed by Trump, White House officials wrote that Duffy should consult with the chair of the Council on Environmental Quality and follow “applicable law” in the regulatory cull.

The executive order also includes a clause directing Duffy to reevaluate, amend, or rescind a slate of launch-safety regulations written during the first Trump administration. The FAA published the new regulations, known as Part 450, in 2020, and they went into effect in 2021, but space companies have complained they are too cumbersome and have slowed down the license approval process.

And there’s more. Trump ordered NASA, the military, and DOT to eliminate duplicative reviews for spaceport development. This is particularly pertinent at federally owned launch ranges like those at Cape Canaveral, Florida; Vandenberg Space Force Base, California; and Wallops Island, Virginia.

The Trump administration also plans to make the head of the FAA’s Office of Commercial Space Transportation a political appointee. This office oversees commercial launch and reentry licensing and was previously led by a career civil servant. Duffy will also hire an advisor on deregulation in the commercial spaceflight industry to join DOT, and the Office of Space Commerce will be elevated to a more prominent position within the Commerce Department.

“It is the policy of the United States to enhance American greatness in space by enabling a competitive launch marketplace and substantially increasing commercial space launch cadence and novel space activities by 2030,” Trump’s executive order reads. “To accomplish this, the federal government will streamline commercial license and permit approvals for United States-based operators.”

News of the executive order was reported last month by ProPublica, which wrote that the Trump administration was circulating draft language among federal agencies to slash rules to protect the environment and the public from the dangers of rocket launches. The executive order signed by Trump and released by the White House on Wednesday confirms ProPublica’s reporting.

Jared Margolis, a senior attorney for the Center for Biological Diversity, criticized the Trump administration’s move.

“This reckless order puts people and wildlife at risk from private companies launching giant rockets that often explode and wreak devastation on surrounding areas,” Margolis said in a statement. “Bending the knee to powerful corporations by allowing federal agencies to ignore bedrock environmental laws is incredibly dangerous and puts all of us in harm’s way. This is clearly not in the public interest.”

Duffy, the first person to lead NASA and another federal department at the same time, argued the order is important to sustain economic growth in the space industry.

“By slashing red tape tying up spaceport construction, streamlining launch licenses so they can occur at scale, and creating high-level space positions in government, we can unleash the next wave of innovation,” Duffy said in a statement. “At NASA, this means continuing to work with commercial space companies and improving our spaceports’ ability to launch.”

Nipping NEPA

The executive order is emblematic of the Trump administration’s broader push to curtail environmental reviews for large infrastructure projects.

The White House has already directed federal agencies to repeal regulations enforcing the National Environmental Policy Act (NEPA), a 1969 law that requires the feds prepare environmental assessments and environmental impact statements to evaluate the effects of government actions—such as licensing approvals—on the environment.

Regarding commercial spaceflight, the White House ordered the Transportation Department to create a list of activities officials there believe are not subject to NEPA and establish exclusions under NEPA for launch and reentry licenses.

The changes to the environmental review process might be the most controversial part of Trump’s new executive order. Another section of the order—the attempt to reform or rescind the so-called Part 450 launch and reentry regulations—appears to have bipartisan support in Congress.

The FAA started implementing its new Part 450 commercial launch and reentry regulations less than five years ago after writing the rules in response to another Trump executive order signed in 2018. Part 450 was intended to streamline the launch approval process by allowing companies to submit applications for a series of launches or reentries, rather than requiring a new license for each mission.

But industry officials quickly criticized the new regulations, which they said didn’t account for rapid iteration of rockets and spacecraft like SpaceX’s enormous Starship/Super Heavy launch vehicle. The FAA approved a SpaceX request in May to increase the number of approved Starship launches from five to 25 per year from the company’s base in Starship, Texas, near the US-Mexico border.

Last year, the FAA’s leadership under the Biden administration established a committee to examine the shortcomings of Part 450. The Republican and Democratic leaders of the House Science, Space, and Technology Committee submitted a joint request in February for the Government Accountability Office to conduct an independent review of the FAA’s Part 450 regulations.

“Reforming and streamlining commercial launch regulations and licensing is an area the Biden administration knew needed reform,” wrote Laura Forczyk, founder and executive director of the space consulting firm Astralytical, in a post on X. “However, little was done. Will more be done with this executive order? I hope so. This was needed years ago.”

Dave Cavossa, president of the Commercial Spaceflight Federation, applauded the Trump administration’s regulatory policy.

“This executive order will strengthen and grow the US commercial space industry by cutting red tape while maintaining a commitment to public safety, benefitting the American people and the US government that are increasingly reliant on space for our national and economic security,” Cavossa said in a statement.

Specific language in the new Trump executive order calls for the FAA to evaluate which regulations should be waived for hybrid launch or reentry vehicles that hold FAA airworthiness certificates, and which requirements should be remitted for rockets with a flight termination system, an explosive charge designed to destroy a launch vehicle if it veers off its pre-approved course after liftoff. These are similar to the topics the Biden-era FAA was looking at last year.

The new Trump administration policy also seeks to limit the authority of state officials in enforcing their own environmental rules related to the construction or operation of spaceports.

This is especially relevant after the California Coastal Commission rejected a proposal by SpaceX to double its launch cadence at Vandenberg Space Force Base, a spaceport located roughly 140 miles (225 kilometers) northwest of Los Angeles. The Space Force, which owns Vandenberg and is one of SpaceX’s primary customers, backs SpaceX’s push for more launches.

Finally, the order gives the Department of Commerce responsibility for authorizing “novel space activities” such as in-space assembly and manufacturing, asteroid and planetary mining, and missions to remove space debris from orbit.

With Trump’s cutbacks, crew heads for ISS unsure of when they’ll come back

The next four-person team to live and work aboard the International Space Station departed from NASA’s Kennedy Space Center in Florida on Friday, taking aim at the massive orbiting research complex for a planned stay of six to eight months.

Spacecraft commander Zena Cardman leads the mission, designated Crew-11, that lifted off from Florida’s Space Coast at 11: 43 am EDT (15: 43 UTC) on Friday. Sitting to her right inside SpaceX’s Crew Dragon Endeavour capsule was veteran NASA astronaut Mike Fincke, serving as the vehicle pilot. Flanking the commander and pilot were two mission specialists: Kimiya Yui of Japan and Oleg Platonov of Russia.

Cardman and her crewmates rode a Falcon 9 rocket off the launch pad and headed northeast over the Atlantic Ocean, lining up with the space station’s orbit to set the stage for an automated docking at the complex early Saturday.

Goodbye LZ-1

The Falcon 9’s reusable first stage booster detached and returned to a propulsive touchdown at Landing Zone 1 (LZ-1) at Cape Canaveral Space Force Station, a few miles south of the launch site. This was the 53rd and final rocket landing at LZ-1 since SpaceX aced the first intact recovery of a Falcon 9 booster there on December 21, 2015.

On most of SpaceX’s missions, Falcon 9 boosters land on the company’s offshore drone ships hundreds of miles downrange from the launch site. For launches with enough fuel margin, the first stage can return to an onshore landing. But the Space Force, which leases out the landing zones to SpaceX, wants to convert the site of LZ-1 into a launch site for another rocket company.

SpaceX will move onshore rocket landings to new landing zones to be constructed next to the two Falcon 9 launch pads at the Florida spaceport. Landing Zone 2, located adjacent to Landing Zone 1, will also be decommissioned and handed back over to the Space Force once SpaceX activates the new landing sites.

“We’re working with the Cape and with the Kennedy Space Center folks to figure out the right time to make that transition from Landing Zone 2 in the future,” said Bill Gerstenmaier, SpaceX’s vice president of build and flight reliability. “But I think we’ll stay with Landing Zone 2 at least near-term, for a little while, and then look at the right time to move to the other areas.”

Meanwhile, the Falcon 9’s second stage fired its single engine to accelerate the Crew Dragon spacecraft into low-Earth orbit. Less than 10 minutes after liftoff, the capsule separated from the second stage to wrap up the 159th consecutive successful launch of a Falcon 9 rocket.

“I have no emotions but joy right now,” Cardman said moments after arriving in orbit. “That was absolutely transcendent, the ride of a lifetime.”

This is the first trip to space for Cardman, a 37-year-old geobiologist and Antarctic explorer selected as a NASA astronaut in 2017. She was assigned to command a Dragon flight to the ISS last year, but NASA bumped her and another astronaut from the mission to make room for the spacecraft to return the two astronauts left behind on the station by Boeing’s troubled Starliner capsule.

Mike Fincke, 58, is beginning his fourth spaceflight after previous launches on Russian Soyuz spacecraft and NASA’s space shuttle. He was previously training to fly on the Starliner spacecraft’s first long-duration mission, but NASA moved him to Dragon as the Boeing program faced more delays.

“Boy, it’s great to be back in orbit!” Fincke said. “Thank you to SpaceX and NASA for getting us here. What a ride!”

Yui is on his second flight to orbit. The 55-year-old former fighter pilot in the Japanese Air Self-Defense Force spent 141 days in space in 2015. Platonov, a 39-year-old spaceflight rookie, was a fighter pilot in the Russian Air Force before training to become a cosmonaut.

A matter of money

There’s some unexpected uncertainty going into this mission about how long the foursome will be in space. Missions sometimes get extended for technical reasons, or because of poor weather in recovery zones on Earth, but there’s something different in play with Crew-11. For the first time, there’s a decent chance that NASA will stretch out this expedition due to money issues.

The Trump administration has proposed across-the-board cuts to most NASA programs, including the International Space Station. The White House’s budget request for NASA in fiscal year 2026, which begins on October 1, calls for an overall cut in agency funding of nearly 25 percent.

The White House proposes a slightly higher reduction by percentage for the International Space Station and crew and cargo transportation to and from the research outpost. The cuts to the ISS would keep the station going through 2030, but with a smaller crew and a reduced capacity for research. Effectively, the ISS would limp toward retirement after more than 30 years in orbit.

Steve Stich, NASA’s commercial crew program manager, said the agency’s engineers are working with SpaceX to ensure the Dragon spacecraft can stay in orbit for at least eight months. The current certification limit is seven months, although officials waived the limit for one Dragon mission that lasted longer.

“When we launch, we have a mission duration that’s baseline,” Stich said in a July 10 press conference. “And then we can extend [the] mission in real-time, as needed, as we better understand… the reconciliation bill and the appropriations process and what that means relative to the overall station manifest.”

An update this week provided by Dana Weigel, NASA’s ISS program manager, indicated that officials are still planning for Crew-11 to stay in space a little longer than usual.

“We are looking at the potential to extend this current flight, Crew-11,” Weigel said Wednesday. “There are a few more months worth of work to do first.”

Budget bills advanced in the Senate and House of Representatives in July would maintain funding for most NASA programs, including the ISS and transportation, close to this year’s levels. But it’s no guarantee that Congress will pass an appropriations bill for NASA before the deadline of midnight on October 1. It’s also unknown whether President Donald Trump would sign a budget bill into law that rejects his administration’s cuts.

If Congress doesn’t act, lawmakers must pass a continuing resolution as a temporary stopgap measure or accept a government shutdown. Some members of Congress are also concerned that the Trump administration might simply refuse to spend money allotted to NASA and other federal agencies in any budget bill. This move, called impoundment, would be controversial, and its legality would likely have to be adjudicated in the courts.

A separate amendment added in Congress to a so-called reconciliation bill and signed into law by Trump on July 4 also adds $1.25 billion for ISS operations through 2029. “We’re still evaluating how that’s going to affect operations going forward, but it’s a positive step,” said Ken Bowersox, NASA’s associate administrator for space operations.

Suffice it to say that while Congress has signaled its intention to keep funding the ISS and many other NASA programs, the amount of money the space agency will actually receive remains uncertain. Trump appointees have directed NASA managers to prepare to operate as if the White House’s proposed cuts will become reality.

For officials in charge of the International Space Station, this means planning for fewer astronauts, reductions in research output, and longer-duration missions to minimize the number of crew rotation flights NASA must pay for. SpaceX is NASA’s primary contractor for crew rotation missions, using its Dragon spacecraft. NASA has a similar contract with Boeing, but that company’s Starliner spacecraft has not been certified for any operational flights to the station.

SpaceX’s next crew mission to the space station, Crew-12, is scheduled to launch early next year. Weigel said NASA is looking at the “entire spectrum” of options to cut back on the space station’s operations and transportation costs. One of those options would be to launch three crew members on Crew-12 instead of the regular four-person complement.

“We don’t have to answer that right now,” Weigel said. “We can actually wait pretty late to make the crew size smaller if we need to. In terms of cargo vehicles, we’re well-supplied through this fall, so in the short term, I’d say, through the end of this year and the beginning of ’26, things look pretty normal in terms of what we have planned for the program.

“But we’re evaluating things, and we’ll be ready to adjust when the budget is passed and when we figure out where we really land.”

The National Air and Space Museum welcomed the public into five more of its renovated galleries on Monday, including two showcasing spaceflight artifacts. The new exhibitions shine modern light on returning displays and restore the museum’s almost 50-year-old legacy of adding objects that made history but have yet to become historical.

Visitors can again enter through the “Boeing Milestones of Flight Hall,” which has been closed for the past three years and has on display some of the museum’s most iconic items, including John Glenn’s Friendship 7 Mercury capsule and an Apollo lunar module.

From there, visitors can tour through the adjacent “Futures in Space,” a new gallery focused on the different approaches and technology that spaceflight will take in the years to come. Here, the Smithsonian is displaying for the first time objects that were recently donated by commercial spaceflight companies, including items used in space tourism and in growing the low-Earth orbit economy.

“We are thrilled to open this next phase of exhibitions to the public,” said Chris Browne, the John and Adrienne Mars Director of the National Air and Space Museum, in a statement. “Reopening our main hall with so many iconic aerospace artifacts, as well as completely new exhibitions, will give visitors much more to see and enjoy.”

The other three galleries newly open to the public are devoted to aviation history, including the “Barron Hilton Pioneers of Flight,” “World War I: The Birth of Military Aviation,” and the “Allan and Shelley Holt Innovations Gallery.”

What’s new is not yet old

Among the artifacts debuting in “Futures in Space” are a Merlin engine and grid fin that flew on a SpaceX Falcon 9 rocket, Sian Proctor’s pressure suit that she wore on the private Inspiration4 mission in 2021, and a mockup of a New Shepard crew module that Blue Origin has pledged to replace with its first flown capsule when it is retired from flying.

“When the museum first opened back in 1976 and people came here and saw things like the Apollo command module and Neil Armstrong’s spacesuit, or really anything related to human spaceflight, at that point it was all still very recent,” said Matt Shindell, one of the curators behind “Futures in Space,” in an interview with collectSPACE.com. “So when you would come into the museum, it wasn’t so much a history of space but what’s happening now and what could happen next. We wanted to have a gallery that would recapture that feeling.”

Instead of being themed around a single program or period in history, the new gallery invites visitors to consider a series of questions, including: Who decides who goes to space? Why do we go? And what will we do when we get there?

“We really wanted the gallery to be one that engaged visitors in these questions and that centered the experience around what they thought should be happening in the future and what that would mean for them,” said Shindell. “We also have visions of the future presented throughout the gallery, including from popular culture—television shows, movies and comic books—that have explored what the future might look like and what it would mean for the people living through it.”

That is why the gallery also includes R2-D2, or rather a reproduction of the “Star Wars” droid as built by Adam Savage of Tested. In George Lucas’ vision of the future (“a long, long time ago”), Astromech droids serve as spacecraft navigators, mechanics, and companion aides.

Beyond the artifacts and exhibits (which also include an immersive 3D-printed Mars habitat and Yuri Gagarin’s training pressure suit), there is a stage and seating area at the center of “Futures.”

“I think of it as a TED Talk-style stage,” said Shindell. “We’re hoping to bring in people from industry, stakeholders, people who have flown, people who are getting ready to fly, and people who have ideas about what should be happening to come and talk to visitors from that stage about the same questions that we’re asking in the gallery.”

Modernized “Milestones”

The artifacts presented in the “Boeing Milestones of Flight” are mostly the same as they were before the hall was closed in 2022. The hall underwent a renovation in 2014 ahead of the museum’s 40th anniversary, so its displays did not need another redesign.

Still, the gallery looks new due to the work done surrounding the objects.

“What is new for the ‘Boeing Milestones of Flight Hall’ is, at some level, most noticeably the floor and media elements,” said Margaret Weitekamp, curator and division chair at the National Air and Space Museum, in an interview.

“We have a wonderful 123-foot (37-meter) media band that goes across the front of the mezzanine, and we have 20 different slide shows that work as a digest of what you’ll find in the new galleries throughout the building,” said Weitekamp. “So as people come into the Boeing Milestones of Flight Hall, they’ll be greeted by that and get a taste of what they’re going to see inside.”

And then there is the new flooring. In the past, the hall had been lined in maroon or dark gray carpet. It is now a much lighter color terrazzo.

“It really brightens up the room,” Weitekamp told collectsPACE.

“Also, you’ll notice that as you are going up and down the hallways, there are medallions embedded in the floor that display quotes from significant aviation and spaceflight figures. So we’ve been able to put some quotes from Carl Sagan, Sally Ride, and Chuck Yeager into the floor,” she said.

Visitors should also pay attention to what look like lines of dashes converging at the hall’s center. The design is an update to a NASA graphic.

“We have a revised version of the pulsar map from Pioneer 10 and 11 and the Voyager interstellar record,” said Weitekamp, referring to the representation of the location of Earth for any extraterrestrial species that might discover the probes in the future. “The map located Earth’s solar system with relationship to 14 pulsars.”

When the Pioneer and Voyager spacecraft were launched, astronomers didn’t know that pulsars (or rotating neutron stars) slow down over time.

“So we worked with a colleague of ours to make it a map to our solar system as would be accurate for 2026, which will mark the 50th anniversary of the museum’s building and the 250th birthday of the nation,” Weitekamp said.

Thirteen open, eight to go

Monday’s opening followed an earlier debut of eight reimagined galleries in 2022. Also open is the renovated Lockheed Martin IMAX Theater, which joins the planetarium, the museum store, and the Mars Café that were reopened earlier.

“We are nearing the end of this multi-year renovation project,” said Browne. “We look forward to welcoming many more people into these modernized and inspiring new spaces,”

Eight more exhibitions are scheduled to open next year in time for the 50th anniversary of the National Air and Space Museum. Among those galleries are three that are focused on space: “At Home in Space,” “National Science Foundation Discovering Our Universe,” and “RTX Living in the Space Age Hall.”

Admission to the National Air and Space Museum and the new galleries is free, but timed-entry passes, available from the Smithsonian’s website, are required.

Starlink kept me connected to the Internet without fail—until Thursday

broadband, Space, spacex, starlink, Ukraine / Beth Washington / July 26, 2025

A rare global interruption in the Starlink satellite Internet network knocked subscribers offline for more than two hours on Thursday, the longest widespread outage since SpaceX opened the service to consumers nearly five years ago.

The outage affected civilian and military users, creating an inconvenience for many but cutting off a critical lifeline for those who rely on Starlink for military operations, health care, and other applications.

Michael Nicolls, SpaceX’s vice president of Starlink engineering, wrote on X that the network outage lasted approximately 2.5 hours.

“The outage was due to failure of key internal software services that operate the core network,” Nicolls wrote. “We apologize for the temporary disruption in our service; we are deeply committed to providing a highly reliable network, and will fully root cause this issue and ensure it does not occur again.”

Elon Musk, SpaceX’s founder and CEO, apologized for the interruption in service on X: “Sorry for the outage. SpaceX will remedy root cause to ensure it doesn’t happen again.”

Effects big and small

The Ukrainian military has been at the leading edge of adopting Starlink services and adapting the system for use in war zones. Ukraine’s exploitation of Starlink connectivity has been instrumental in directing military operations, supporting battlefield communications, and controlling drones engaged in reconnaissance and offensive strikes.

The commander of Ukraine’s drone forces, Robert Brovdi, confirmed Thursday’s Starlink outage reached his country’s ongoing war with Russia.

“Starlink went down across the entire front,” Brovdi wrote on Telegram. “Combat operations were carried out without broadcasts; reconnaissance was carried out … using shock weapons.”

Brovdi added that the interruption in service illustrates the importance of having multiple paths of connectivity, especially for time-critical military operations. “This incident, which lasted 150 minutes in the war, points to bottlenecks,” he wrote, urging the military to diversify its means of communication and connectivity.

Oleksandr Dmitriev, the founder of a Ukrainian system that centralizes feeds from thousands of drone crews across the frontline, told Reuters the outage was an example of the shortcomings of relying on cloud services for military operations, particularly battlefield drone reconnaissance.

Welcome to Edition 8.04 of the Rocket Report! The Pentagon’s Golden Dome missile defense shield will be a lot of things. Along with new sensors, command and control systems, and satellites, Golden Dome will require a lot of rockets. The pieces of the Golden Dome architecture operating in orbit will ride to space on commercial launch vehicles. And Golden Dome’s space-based interceptors will essentially be designed as flying fuel tanks with rocket engines. This shouldn’t be overlooked, and that’s why we include a couple of entries discussing Golden Dome in this week’s Rocket Report.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Space-based interceptors are a real challenge. The newly installed head of the Pentagon’s Golden Dome missile defense shield knows the clock is ticking to show President Donald Trump some results before the end of his term in the White House, Ars reports. Gen. Michael Guetlein identified command-and-control and the development of space-based interceptors as two of the most pressing technical challenges for Golden Dome. He believes the command-and-control problem can be “overcome in pretty short order.” The space-based interceptor piece of the architecture is a different story.

Proven physics, unproven economics … “I think the real technical challenge will be building the space-based interceptor,” Guetlein said. “That technology exists. I believe we have proven every element of the physics that we can make it work. What we have not proven is, first, can I do it economically, and then second, can I do it at scale? Can I build enough satellites to get after the threat? Can I expand the industrial base fast enough to build those satellites? Do I have enough raw materials, etc.?” Military officials haven’t said how many space-based interceptors will be required for Golden Dome, but outside estimates put the number in the thousands.

One big defense prime is posturing for Golden Dome. Northrop Grumman is conducting ground-based testing related to space-based interceptors as part of a competition for that segment of the Trump administration’s Golden Dome missile-defense initiative, The War Zone reports. Kathy Warden, Northrop Grumman’s CEO, highlighted the company’s work on space-based interceptors, as well as broader business opportunities stemming from Golden Dome, during a quarterly earnings call this week. Warden identified Northrop’s work in radars, drones, and command-and-control systems as potentially applicable to Golden Dome.

But here’s the real news … “It will also include new innovation, like space-based interceptors, which we’re testing now,” Warden continued. “These are ground-based tests today, and we are in competition, obviously, so not a lot of detail that I can provide here.” Warden declined to respond directly to a question about how the space-based interceptors Northrop Grumman is developing now will actually defeat their targets.

Trump may slash environmental rules for rocket launches. The Trump administration is considering slashing rules meant to protect the environment and the public during commercial rocket launches, changes that companies like Elon Musk’s SpaceX have long sought, ProPublica reports. A draft executive order being circulated among federal agencies, and viewed by ProPublica, directs Secretary of Transportation Sean Duffy to “use all available authorities to eliminate or expedite” environmental reviews for launch licenses. It could also, in time, require states to allow more launches or even more launch sites along their coastlines.

Getting political at the FAA … The order is a step toward the rollback of federal oversight that Musk, who has fought bitterly with the Federal Aviation Administration over his space operations, and others have pushed for. Commercial rocket launches have grown exponentially more frequent in recent years. In addition to slashing environmental rules, the draft executive order would make the head of the FAA’s Office of Commercial Space Transportation a political appointee. This is currently a civil servant position, but the last head of the office took a voluntary separation offer earlier this year.

There’s a SPAC for that. An unproven small launch startup is partnering with a severely depleted SPAC trust to do the impossible: go public in a deal they say will be valued at $400 million, TechCrunch reports. Innovative Rocket Technologies Inc., or iRocket, is set to merge with a Special Purpose Acquisition Company, or SPAC, founded by former Commerce Secretary Wilbur Ross. But the most recent regulatory filings by this SPAC showed it was in a tenuous financial position last year, with just $1.6 million held in trust. Likewise, iRocket isn’t flooded with cash. The company has raised only a few million in venture funding, a fraction of what would be needed to develop and test the company’s small orbital-class rocket, named Shockwave.

SpaceX traces a path to orbit for NASA. Two NASA satellites soared into orbit from California aboard a SpaceX Falcon 9 rocket Wednesday, commencing a $170 million mission to study a phenomenon of space physics that has eluded researchers since the dawn of the Space Age, Ars reports. The twin spacecraft are part of the NASA-funded TRACERS mission, which will spend at least a year measuring plasma conditions in narrow regions of Earth’s magnetic field known as polar cusps. As the name suggests, these regions are located over the poles. They play an important but poorly understood role in creating colorful auroras as plasma streaming out from the Sun interacts with the magnetic field surrounding Earth. The same process drives geomagnetic storms capable of disrupting GPS navigation, radio communications, electrical grids, and satellite operations.

Plenty of room for more … The TRACERS satellites are relatively small, each about the size of a washing machine, so they filled only a fraction of the capacity of SpaceX’s Falcon 9 rocket. Three other small NASA tech demo payloads hitched a ride to orbit with TRACERS, kicking off missions to test an experimental communications terminal, demonstrate an innovative scalable satellite platform made of individual building blocks, and study the link between Earth’s atmosphere and the Van Allen radiation belts. In addition to those missions, the European Space Agency launched its own CubeSat to test 5G communications from orbit. Five smallsats from an Australian company rounded out the group. Still, the Falcon 9 rocket’s payload shroud was filled with less than a quarter of the payload mass it could have delivered to the TRACERS mission’s targeted Sun-synchronous orbit.

Tianlong launch pad ready for action. Chinese startup Space Pioneer has completed a launch pad at Jiuquan spaceport in northwestern China for its Tianlong 3 liquid propellent rocket ahead of a first orbital launch, Space News reports. Space Pioneer said the launch pad passed an acceptance test, and ground crews raised a full-scale model of the Tianlong 3 rocket on the launch pad. “The rehearsal test was successfully completed,” said Space Pioneer, one of China’s leading private launch companies. The activation of the launch pad followed a couple of weeks after Space Pioneer announced the completion of static loads testing on Tianlong 3.

More to come … While this is an important step forward for Space Pioneer, construction of the launch pad is just one element the company needs to finish before Tianlong 3 can lift off for the first time. In June 2024, the company ignited Tianlong 3’s nine-engine first stage on a test stand in China. But the rocket broke free of its moorings on the test stand and unexpectedly climbed into the sky before crashing in a fireball nearby. Space Pioneer says the “weak design of the rocket’s tail structure was the direct cause of the failure” last year. The company hasn’t identified next steps for Tianlong 3, or when it might be ready to fly. Tianlong 3 is a kerosene-fueled rocket with nine main engines, similar in design architecture and payload capacity to SpaceX’s Falcon 9. Also, like Falcon 9, Tianlong 3 is supposed to have a recoverable and reusable first stage booster.

Dredging up an issue at Wallops. Rocket Lab has asked regulators for permission to transport oversized Neutron rocket structures through shallow waters to a spaceport off the coast of Virginia as it races to meet a September delivery deadline, TechCrunch reports. The request, which was made in July, is a temporary stopgap while the company awaits federal clearance to dredge a permanent channel to the Wallops Island site. Rocket Lab plans to launch its Neutron medium-lift rocket from the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Virginia, a lower-traffic spaceport that’s surrounded by shallow channels and waterways. Rocket Lab has a sizable checklist to tick off before Neutron can make its orbital debut, like mating the rocket stages, performing a “wet dress” rehearsal, and getting its launch license from the Federal Aviation Administration. Before any of that can happen, the rocket hardware needs to make it onto the island from Rocket Lab’s factory on the nearby mainland.

Kedging bets … Access to the channel leading to Wallops Island is currently available only at low tides. So, Rocket Lab submitted an application earlier this year to dredge the channel. The dredging project was approved by the Virginia Marine Resources Commission in May, but the company has yet to start digging because it’s still awaiting federal sign-off from the Army Corps of Engineers. As the company waits for federal approval, Rocket Lab is seeking permission to use a temporary method called “kedging” to ensure the first five hardware deliveries can arrive on schedule starting in September. We don’t cover maritime issues in the Rocket Report, but if you’re interested in learning a little about kedging, here’s a link.

Any better ideas for an Exploration Upper Stage? Not surprisingly, Congress is pushing back against the Trump administration’s proposal to cancel the Space Launch System, the behemoth rocket NASA has developed to propel astronauts back to the Moon. But legislation making its way through the House of Representatives includes an interesting provision that would direct NASA to evaluate alternatives for the Boeing-built Exploration Upper Stage, an upgrade for the SLS rocket set to debut on its fourth flight, Ars reports. Essentially, the House Appropriations Committee is telling NASA to look for cheaper, faster options for a new SLS upper stage.

CYA EUS? … The four-engine Exploration Upper Stage, or EUS, is an expensive undertaking. Last year, NASA’s inspector general reported that the new upper stage’s development costs had ballooned from $962 million to $2.8 billion, and the project had been delayed more than six years. That’s almost a year-for-year delay since NASA and Boeing started development of the EUS. So, what are the options if NASA went with a new upper stage for the SLS rocket? One possibility is a modified version of United Launch Alliance’s dual-engine Centaur V upper stage that flies on the Vulcan rocket. It’s no longer possible to keep flying the SLS rocket’s existing single-engine upper stage because ULA has shut down the production line for it.

Raising Super Heavy from the deep. For the second time, SpaceX has retrieved an engine section from one of its Super Heavy boosters from the Gulf of Mexico, NASASpaceflight.com reports. Images posted on social media showed the tail end of a Super Heavy booster being raised from the sea off the coast of northern Mexico. Most of the rocket’s 33 Raptor engines appear to still be attached to the lower section of the stainless steel booster. Online sleuths who closely track SpaceX’s activities at Starbase, Texas, have concluded the rocket recovered from the Gulf is Booster 13, which flew on the sixth test flight of the Starship mega-rocket last November. The booster ditched in the ocean after aborting an attempted catch back at the launch pad in South Texas.

But why? … SpaceX recovered the engine section of a different Super Heavy booster from the Gulf last year. The company’s motivation for salvaging the wreckage is unclear. “Speculated reasons include engineering research, environmental mitigation, or even historical preservation,” NASASpaceflight reports.

SpaceX launches a pair of NASA satellites to probe the origins of space weather

Two NASA satellites rocketed into orbit from California aboard a SpaceX Falcon 9 rocket Wednesday, commencing a $170 million mission to study a phenomenon of space physics that has eluded researchers since the dawn of the Space Age.

The twin spacecraft are part of the NASA-funded TRACERS mission, which will spend at least a year measuring plasma conditions in narrow regions of Earth’s magnetic field known as polar cusps. As the name suggests, these regions are located over the poles. They play an important but poorly understood role in creating colorful auroras as plasma streaming out from the Sun interacts with the magnetic field surrounding Earth.

The same process drives geomagnetic storms capable of disrupting GPS navigation, radio communications, electrical grids, and satellite operations. These outbursts are usually triggered by solar flares or coronal mass ejections that send blobs of plasma out into the Solar System. If one of these flows happens to be aimed at Earth, we are treated with auroras but vulnerable to the storm’s harmful effects.

For example, an extreme geomagnetic storm last year degraded GPS navigation signals, resulting in more than $500 million in economic losses in the agriculture sector as farms temporarily suspended spring planting. In 2022, a period of elevated solar activity contributed to the loss of 40 SpaceX Starlink satellites.

“Understanding our Sun and the space weather it produces is more important to us here on Earth, I think, than most realize,” said Joe Westlake, director of NASA’s heliophysics division.

The launch of TRACERS was delayed 24 hours after a regional power outage disrupted air traffic control over the Pacific Ocean near the Falcon 9 launch site on California’s Central Coast, according to the Federal Aviation Administration. SpaceX called off the countdown Tuesday less than a minute before liftoff, then rescheduled the flight for Wednesday.

TRACERS, short for Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, will study a process known as magnetic reconnection. As particles in the solar wind head out into the Solar System at up to 1 million mph, they bring along pieces of the Sun’s magnetic field. When the solar wind reaches our neighborhood, it begins interacting with Earth’s magnetic field.

The high-energy collision breaks and reconnects magnetic field lines, flinging solar wind particles across Earth’s magnetosphere at speeds that can approach the speed of light. Earth’s field draws some of these particles into the polar cusps, down toward the upper atmosphere. This is what creates dazzling auroral light shows and potentially damaging geomagnetic storms.

Over our heads

But scientists still aren’t sure how it all works, despite the fact that it’s happening right over our heads, within the reach of countless satellites in low-Earth orbit. But a single spacecraft won’t do the job. Scientists need at least two spacecraft, each positioned in bespoke polar orbits and specially instrumented to measure magnetic fields, electric fields, electrons, and ions.

That’s because magnetic reconnection is a dynamic process, and a single satellite would provide just a snapshot of conditions over the polar cusps every 90 minutes. By the time the satellite comes back around on another orbit, conditions will have changed, but scientists wouldn’t know how or why, according to David Miles, principal investigator for the TRACERS mission at the University of Iowa.

“You can’t tell, is that because the system itself is changing?” Miles said. “Is that because this magnetic reconnection, the coupling process, is moving around? Is it turning on and off, and if it’s turning on and off, how quickly can it do it? Those are fundamental things that we need to understand… how the solar wind arriving at the Earth does or doesn’t transfer energy to the Earth system, which has this downstream effect of space weather.”

This is why the tandem part of the TRACERS name is important. The novel part of this mission is it features two identical spacecraft, each about the size of a washing machine flying at an altitude of 367 miles (590 kilometers). Over the course of the next few weeks, the TRACERS satellites will drift into a formation with one trailing the other by about two minutes as they zip around the world at nearly five miles per second. This positioning will allow the satellites to sample the polar cusps one right after the other, instead of forcing scientists to wait another 90 minutes for a data refresh.

With TRACERS, scientists hope to pick apart smaller, fast-moving changes with each satellite pass. Within a year, TRACERS should collect 3,000 measurements of magnetic reconnections, a sample size large enough to start identifying why some space weather events evolve differently than others.

“Not only will it get a global picture of reconnection in the magnetosphere, but it’s also going to be able to statistically study how reconnection depends on the state of the solar wind,” said John Dorelli, TRACERS mission scientist at NASA’s Goddard Space Flight Center. “This is going to really help us understand how to predict space weather in the magnetosphere.”

“If we can understand these various different situations, whether it happens suddenly if you have one particular kind of event, or it happens in lots of different places, then we have a better way to model that and say, ‘Ah, here’s the likelihood of seeing a certain kind of effect that would affect humans,'” said Craig Kletzing, the principal investigator who led the TRACERS science team until his death in 2023.

There is broader knowledge to be gained with a mission like TRACERS. Magnetic reconnection is ubiquitous throughout the Universe, and the same physical processes produce solar flares and coronal mass ejections from the Sun.

Hitchhiking to orbit

Several other satellites shared the ride to space with TRACERS on Wednesday.

These secondary payloads included a NASA-sponsored mission named PExT, a small technology demonstration satellite carrying an experimental communications package capable of connecting with three different networks: NASA’s government-owned Tracking and Data Relay Satellites (TDRS) and commercial satellite networks owned by SES and Viasat.

What’s unique about the Polylingual Experimental Terminal, or PExT, is its ability to roam across multiple satellite relay networks. The International Space Station and other satellites in low-Earth orbit currently connect to controllers on the ground through NASA’s TDRS satellites. But NASA will retire its TDRS satellites in the 2030s and begin purchasing data relay services using commercial satellite networks.

The space agency expects to have multiple data relay providers, so radios on future NASA satellites must be flexible enough to switch between networks mid-mission. PExT is a pathfinder for these future missions.

Another NASA-funded tech demo named Athena EPIC was also aboard the Falcon 9 rocket. Led by NASA’s Langley Research Center, this mission uses a scalable satellite platform developed by a company named NovaWurks, using building blocks to piece together everything a spacecraft needs to operate in space.

Athena EPIC hosts a single science instrument to measure how much energy Earth radiates into space, an important data point for climate research. But the mission’s real goal is to showcase how an adaptable satellite design, such as this one using NovaWurks’ building block approach, might be useful for future NASA missions.

A handful of other payloads rounded out the payload list for Wednesday’s launch. They included REAL, a NASA-funded CubeSat project to investigate the Van Allen radiation belts and space weather, and LIDE, an experimental 5G communications satellite backed by the European Space Agency. Five commercial spacecraft from the Australian company Skykraft also launched to join a constellation of small satellites to provide tracking and voice communications between air traffic controllers and aircraft over remote parts of the world.

Trump wants to “eliminate or expedite” environmental rules for rocket launches

commercial launches, elon musk, fee, NASA, Space, spacex, syndication / 9u50fv / July 22, 2025

Who cares about environmental impacts?

SpaceX, other commercial launch firms, have been seeking this change in policy.

In the background, a Falcon 9 rocket climbs away from Space Launch Complex 40 at Cape Canaveral Space Force Station, Florida. Another Falcon 9 stands on its launch pad at neighboring Kennedy Space Center awaiting its opportunity to fly.

The Trump administration is considering slashing rules meant to protect the environment and the public during commercial rocket launches, changes that companies like Elon Musk’s SpaceX have long sought.

A draft executive order being circulated among federal agencies, and viewed by ProPublica, directs Secretary of Transportation Sean Duffy to “use all available authorities to eliminate or expedite” environmental reviews for launch licenses. It could also, in time, require states to allow more launches or even more launch sites—known as spaceports—along their coastlines.

The order is a step toward the rollback of federal oversight that Musk, who has fought bitterly with the Federal Aviation Administration over his space operations, and others have pushed for. Commercial rocket launches have grown exponentially more frequent in recent years.

Critics warn such a move could have dangerous consequences.

“It would not be reasonable for them to be rescinding regulations that are there to protect the public interest, and the public, from harm,” said Jared Margolis, a senior attorney for the Center for Biological Diversity, a nonprofit that works to protect animals and the environment. “And that’s my fear here: Are they going to change things in a way that puts people at risk, that puts habitats and wildlife at risk?”

The White House did not answer questions about the draft order.

“The Trump administration is committed to cementing America’s dominance in space without compromising public safety or national security,” said White House spokesperson Kush Desai. “Unless announced by President Trump, however, discussion about any potential policy changes should be deemed speculation.”

The order would give Trump even more direct control over the space industry’s chief regulator by turning the civil servant position leading the FAA’s Office of Commercial Space Transportation into a political appointment. The last head of the office and two other top officials recently took voluntary separation offers.

The order would also create a new adviser to the transportation secretary to shepherd in deregulation of the space industry.

The draft order comes as SpaceX is ramping up its ambitious project to build a reusable deep-space rocket to carry people to Earth’s orbit, the moon and eventually Mars. The rocket, called Starship, is the largest, most powerful ever built, standing 403 feet tall with its booster. The company has hit some milestones but has also been beset by problems, as three of the rockets launched from Texas this year have exploded—disrupting air traffic and raining debris on beaches and roads in the Caribbean and Gulf waters.

The draft order also seeks to restrict the authority of state coastal officials who have challenged commercial launch companies like SpaceX, documents show. It could lead to federal officials interfering with state efforts to enforce their environmental rules when they conflict with the construction or operation of spaceports.

Derek Brockbank, executive director for the Coastal States Organization, said the proposed executive order could ultimately force state commissions to prioritize spaceport infrastructure over other land uses, such as renewable energy, waterfront development, or coastal restoration, along the coastline. His nonprofit represents 34 coastal states and territories.

“It’s concerning that it could potentially undermine the rights of a state to determine how it wants its coast used, which was the very fundamental premise of the congressionally authorized Coastal Zone Management Act,” he said. “We shouldn’t see any president, no matter what their party is, coming in and saying, ‘This is what a state should prioritize or should do.’”

SpaceX is already suing the California Coastal Commission, accusing the agency of political bias and interference with the company’s efforts to increase the number of Falcon 9 rocket launches from Vandenberg Space Force Base. The reusable Falcon 9 is SpaceX’s workhorse rocket, ferrying satellites to orbit and astronauts to the International Space Station.

The changes outlined in the order would greatly benefit SpaceX, which launches far more rockets into space than any other company in the US. But it would also help rivals such as Jeff Bezos’ Blue Origin and California-based Rocket Lab. The companies have been pushing to pare down oversight for years, warning that the US is racing with China to return to the moon—in hopes of mining resources like water and rare earth metals and using it as a stepping stone to Mars—and could lose if regulations don’t allow US companies to move faster, said Dave Cavossa, president of the Commercial Space Federation, a trade group that represents eight launch companies, including SpaceX, Blue Origin, and Rocket Lab.

“It sounds like they’ve been listening to industry, because all of those things are things that we’ve been advocating for strongly,” Cavossa said when asked about the contents of the draft order.

Cavossa said he sees “some sort of environmental review process” continuing to take place. “What we’re talking about doing is right-sizing it,” he said.

He added, “We can’t handle a yearlong delay for launch licenses.”

The former head of the FAA’s commercial space office said at a Congressional hearing last September that the office took an average of 151 days to issue a new license during the previous 11 years.

Commercial space launches have boomed in recent years—from 26 in 2019 to 157 last year. With more than 500 total launches, mostly from Texas, Florida, and California, SpaceX has been responsible for the lion’s share, according to FAA data.

But the company has tangled with the FAA, which last year proposed fining it $633,000 for violations related to two of its launches. The FAA did not answer a question last week about the status of the proposed fine.

SpaceX, Blue Origin, Rocket Lab, and the FAA did not respond to requests for comment.

Currently, the FAA’s environmental reviews look at 14 types of potential impacts that include air and water quality, noise pollution, and land use, and provide details about the launches that are not otherwise available. They have at times drawn big responses from the public.

When SpaceX sought to increase its Starship launches in Texas from five to 25 a year, residents and government agencies submitted thousands of comments. Most of the nearly 11,400 publicly posted comments opposed the increase, a ProPublica analysis found. The FAA approved the increase anyway earlier this year. After conducting an environmental assessment for the May launch of SpaceX’s Starship Flight 9 from Texas, the FAA released documents that revealed as many as 175 airline flights could be disrupted and Turks and Caicos’ Providenciales International Airport would need to close during the launch.

In addition to seeking to cut short environmental reviews, the executive order would open the door for the federal government to rescind sections of the federal rule that seeks to keep the public safe during launches and reentries.

The rule, referred to as Part 450, was approved during Trump’s first term and aimed to streamline commercial space regulations and speed approvals of launches. But the rule soon fell out of favor with launch companies, which said the FAA didn’t provide enough guidance on how to comply and was taking too long to review applications.

Musk helped lead the charge. Last September, he told attendees at a conference in Los Angeles, “It really should not be possible to build a giant rocket faster than paper can move from one desk to another.” He called for the resignation of the head of the FAA, who stepped down as Trump took office.

Other operators have expressed similar frustration, and some members of Congress have signaled support for an overhaul. In February, Rep. Brian Babin, R-Texas, and Rep. Zoe Lofgren, D-Calif., signed a letter asking the Government Accountability Office to review the process for approving commercial launches and reentries.

In their letter, Babin and Lofgren wrote they wanted to understand whether the rules are “effectively and efficiently accommodating United States commercial launch and reentry operations, especially as the cadence and technological diversity of such operations continues to increase.

The draft executive order directs the secretary of transportation to “reevaluate, amend, or rescind” sections of Part 450 to “enable a diversified set of operators to achieve an increase in commercial space launch cadence and novel space activities by an order of magnitude by 2030.”

The order also directs the Department of Commerce to streamline regulation of novel space activity, which experts say could include things like mining or making repairs in space, that doesn’t fall under other regulations.

Rocket Report: SpaceX won’t land at Johnston Atoll; new North Sea launch site

rocket report, Space, spacex / Mike M. / July 18, 2025

All the news that’s fit to lift

“Europe is seizing the opportunity to lead.”

Welcome to Edition 8.03 of the Rocket Report! We are at an interesting stage in Europe, with its efforts to commercialize spaceflight. Finally, it seems the long-slumbering continent is waking up to the need to leverage private capital to drive down the costs of space access, and we are seeing more investment flow into European companies. But it is critical that European policymakers make strategic investments across the industry or companies like PLD Space, which outlined big plans this week, will struggle to get off the launch pad.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Avio celebrates freedom from Arianespace. Representatives from Italy, Germany, and France met at the European Space Agency headquarters last week to sign the Launcher Exploitation Declaration, which officially began the transfer of Vega C launch operation responsibilities from Arianespace to the rocket’s builder, Avio, European Spaceflight reports. “It is a historic step that reinforces our nation’s autonomy in access to space and assigns us a strategic responsibility towards Europe,” said Avio CEO Giulio Ranzo. “We are ready to meet this challenge with determination, and we are investing in technologies, expertise, and infrastructure to ensure a competitive service.”

A breaking of long-term partnerships … In addition to securing control over the full exploitation of the Vega launch vehicle family, Italy, through Avio, is also investing in what comes next. The country has committed more than 330 million euros to the development of the MR60 methalox rocket engine and two demonstrator vehicles. These, along with the MR10 engine being developed under the Vega E programme, will support Avio’s preparation of a future reusable launch vehicle. Historically, France, Germany, and Italy have worked together on European launch vehicles. This appears to be another step in breaking up that long-term partnership toward more nationalistic efforts.

PLD Space outlines grand ambitions. PLD Space, Spain’s sole contestant in the European Launcher Challenge, unveiled its long-term strategy at the company’s Industry Days event this week, Payload reports. The company is targeting a production rate of 32 Miura 5 launchers annually by 2030. To achieve this output, PLD plans to deepen its vertical integration, consolidate its supplier network, and begin to serialize its manufacturing process beginning in 2027.

Building up the supply chain … The company’s production plans also call for the parallel development of Miura Next, a heavy-lift vehicle capable of bringing 13 tons to orbit. However, the company will start with the Miura 5 vehicle, which PLD expects to launch for the first time from French Guiana in 2026. Since the beginning of 2024, PLD has invested a total of 50 million euros in its Miura 5 supply chain, consisting of 397 industrial partners, many of which are located in Spain and other European countries. These plans are great, but sooner or later, the 14-year-old company needs to start putting rockets in space. (submitted by EllPeaTea)

New consortium will study space plane. A UK-based space and defense consultant group, Frazer-Nash, will lead a program to design a vehicle and its integrated systems with the goal of building and flying a Mach 5-capable aircraft at the edge of space by early 2031. This so-called INVICTUS program was funded with a 7 million-euro grant from the European Space Agency and is seen as a stepping stone toward developing a reusable space plane that takes off and lands horizontally from a runway.

Seeking to lead a new era of flight … Over 12 months, INVICTUS has been tasked to deliver the concept and elements of the preliminary design of the full flight system. It will attempt to demonstrate the efficacy of hydrogen-fueled, precooled air-breathing propulsion at hypersonic speeds, technology that will ultimately enable horizontal take-off. “With INVICTUS, Europe is seizing the opportunity to lead in technologies that will redefine how we move across the planet and reach beyond it,” said Tommaso Ghidini, head of the Mechanical Department at the European Space Agency.

ESA backs North Sea launch site. A private company developing a launch site in the North Sea, EuroSpaceport, has secured support from the European Space Agency. The company, founded five years ago, is developing a sea-based launch platform built on a repurposed offshore wind turbine service vessel, European Spaceflight reports. Rockets are envisioned to launch from a position 50 to 100 km offshore from the port of Esbjerg, in Denmark.

Seeing the forest for the trees … On Wednesday, EuroSpaceport announced that it had signed an agreement with the European Space Agency and Polish rocket builder SpaceForest to support the first launch from its Spaceport North Sea platform. The company will receive support from the agency through its Boost! Program. SpaceForest has been a recipient of Boost! funding, receiving 2.4 million euros in October 2024. SpaceForest said the mission will be used to verify the launch procedures of its Perun rocket under nominal suborbital conditions. (submitted by EllPeaTea)

Amazon and SpaceX, best frenemies? Maybe not, but for the time being, they appear to be friends of convenience. A Falcon 9 rocket launched from Florida’s Space Coast early on Wednesday with a batch of Internet satellites for Amazon’s Project Kuiper network, thrusting a rival one step closer to competing with SpaceX’s Starlink broadband service. With this launch, Amazon now has 78 Kuiper satellites in orbit, Ars reports. The full Kuiper constellation will consist of 3,232 satellites to provide broadband Internet service to most of the populated world, bringing Amazon in competition with SpaceX’s Starlink network.

Launch is not cheap … Kuiper is an expensive undertaking, estimated at between $16.5 billion and $20 billion by the industry analytics firm Quilty Space. Quilty has concluded that Amazon is spending $10 billion on launch alone, exceeding the company’s original cost estimate for the entire program. Amazon has booked more than 80 launches to deploy the Kuiper constellation, but the company didn’t turn to SpaceX until it had to. A shareholder lawsuit filed in 2023 accused Amazon founder Jeff Bezos and the company’s board of directors of breaching their “fiduciary duty” by not considering SpaceX as an option for launching Kuiper satellites. The plaintiffs in the lawsuit alleged Amazon didn’t consider the Falcon 9 due to an intense and personal rivalry between Bezos and SpaceX founder Elon Musk. Amazon bowed to the allegations and announced a contract with SpaceX for three Falcon 9 launches in December 2023 to provide “additional capacity” for deploying the Kuiper network.

NASA targets end of July for Crew-11. NASA said Monday that it and SpaceX were targeting July 31 for the flight of SpaceX’s Crew-11 mission to the orbiting outpost, Spaceflight Now reports. The mission is led by NASA astronaut Zena Cardman. She will be flying along with fellow NASA astronaut Mike Fincke, Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui and Roscosmos cosmonaut Oleg Platonov.

Pushing Dragon reuse … The mission was moved up from its previously planned August launch window to create more room in the manifest for the arrival of the Cargo Dragon flying the CRS-33 mission. That Dragon will perform a boost of the space station as a demonstration of some of the capabilities SpaceX will use on its US Deorbit Vehicle currently in work. Crew-11 will fly to the orbiting outpost on Crew Dragon Endeavour, which will be its sixth trip to the ISS. This will be the first Crew Dragon spacecraft to fly for a sixth time.

SpaceX won’t use Johnston Atoll for rocket cargo tests. Johnston Atoll, an unincorporated US territory and Pacific island wildlife refuge with a complicated military history, will no longer become a SpaceX reusable rocket test site, Popular Science reports. “The Department of the Air Force has elected to hold the preparation of the Johnston Atoll Environmental Assessment for a proposed rocket cargo landing demonstration on Johnston Atoll in abeyance while the service explores alternative options for implementation,” Air Force spokesperson Laurel Falls said.

Taking a toll on the atoll … Located roughly 860 miles southwest of Hawaii, Johnston Atoll has served as a base for numerous US military operations for over 90 years. Despite this, the atoll remains a home for 14 tropical bird species as part of the Pacific Remote Islands Marine National Monument. The site had been under consideration for tests as part of a military program to deliver cargo around the planet, using suborbital missions on rocket such as SpaceX’s Starship vehicle. The Johnston Atoll plans included the construction of two landing pads that were met with public backlash from wildlife experts and indigenous representatives. (submitted by Tfargo04)

Blue Origin confirms ESCAPADE is up next. On Thursday, Blue Origin said on social media that the second launch of its New Glenn rocket will carry NASA’s ESCAPADE mission as its primary payload. This launch will support ESCAPADE’s science objectives as the twin spacecraft progress on their journey to the Red Planet. Also onboard is a technology demonstration from @Viasat in support of @NASASpaceOps’ Communications Services Project.

Left unsaid was when the launch will occur … The social media post confirms a report from Ars in June, which said the ESCAPADE spacecraft was up next on New Glenn. Previously, the company has said this second launch will take place no earlier than August 15. However, that is less than one month away. Late September is probably the earliest realistic launch date, with October or November more likely for the second flight of the company’s large rocket.

Welcome to Edition 8.02 of the Rocket Report! It’s worth taking a moment to recognize an important anniversary in the history of human spaceflight next week. Fifty years ago, on July 15, 1975, NASA launched a three-man crew on an Apollo spacecraft from Florida and two Russian cosmonauts took off from Kazakhstan, on course to link up in low-Earth orbit two days later. This was the first joint US-Russian human spaceflight mission, laying the foundation for a strained but enduring partnership on the International Space Station. Operations on the ISS are due to wind down in 2030, and the two nations have no serious prospects to continue any partnership in space after decommissioning the station.

Sizing up Europe’s launch challengers. The European Space Agency has selected five launch startups to become eligible for up to 169 million euros ($198 million) in funding to develop alternatives to Arianespace, the continent’s incumbent launch service provider, Ars reports. The five small launch companies ESA selected are Isar Aerospace, MaiaSpace, Rocket Factory Augsburg, PLD Space, and Orbex. Only one of these companies, Isar Aerospace, has attempted to launch a rocket into orbit. Isar’s Spectrum rocket failed moments after liftoff from Norway on a test flight in March. None of these companies is guaranteed an ESA contract or funding. Over the next several months, ESA and the five launch companies will negotiate with European governments for funding leading up to ESA’s ministerial council meeting in November, when ESA member states will set the agency’s budget for at least the next two years. Only then will ESA be ready to sign binding agreements.

Let’s rank ’em … Ars Technica’s space reporters ranked the five selectees for the European Launcher Challenge in order from most likely to least likely to reach orbit. We put Munich-based Isar Aerospace, the most well-funded of the group, at the top of the list after attempting its first orbital launch earlier this year. Paris-based MaiaSpace, backed by ArianeGroup, comes in second, with plans for a partially reusable rocket. Rocket Factory Augsburg, another German company, is in third place after getting close to a launch attempt last year before its first rocket blew up on a test stand. Spanish startup PLD Space is fourth, and Britain’s Orbex rounds out the list. (submitted by EllPeaTea)

Japan’s Interstellar Technologies rakes in more cash. Interstellar Technologies raised 8.9 billion yen ($61.8 million) to boost the development of its Zero rocket and research and development of satellite systems, Space News reports. The money comes from Japanese financial institutions, venture capital funds, and debt financing. Interstellar previously received funding through agreements with the Japanese government and Toyota, which Interstellar says will add expertise to scale manufacturing of the Zero rocket for “high-frequency, cost-effective launches.” The methane-fueled Zero rocket is designed to deploy a payload of up to 1 metric ton (2,200 pounds) into low-Earth orbit. The unfortunate news from Interstellar’s fundraising announcement is that the company has pushed back the debut flight of the Zero rocket until 2027.

Straight up … Interstellar has aspirations beyond launch vehicles. The company is also developing a satellite communications business, and some of the money raised in the latest investment round will go toward this segment of the company. Interstellar is open about comparing its ambition to that of SpaceX. “On the satellite side, Interstellar is developing communications satellites that benefit from the company’s own launch capabilities,” the company said in a statement. “Backed by Japan’s Ministry of Internal Affairs and Communications and JAXA’s Space Strategy Fund, the company is building a vertically integrated model, similar to SpaceX’s approach with Starlink.”

Korean startup completes second-stage qual testing. South Korean launch services company Innospace says it has taken another step toward the inaugural launch of its Hanbit-Nano rocket by the year’s end with the qualification of the second stage, Aviation Week & Space Technology reports. The second stage uses an in-house-developed 34-kilonewton (7,643-pound-thrust) liquid methane engine. Innospace says the engine achieved a combustion time of 300 seconds, maintaining stability of the fuel and oxidizer supply system, structural integrity, and the launch vehicle integrated control system.

A true micro-launcher … Innospace’s rocket is modest in size and capacity, even among its cohorts in the small launch market. The Hanbit-Nano rocket is designed to launch approximately 200 pounds (90 kilograms) of payload into Sun-synchronous orbit. “With the success of this second stage engine certification test, we have completed the development of the upper stage of the Hanbit-Nano launch vehicle,” said Kim Soo-jong, CEO of Innospace. “This is a very symbolic and meaningful technological achievement that demonstrates the technological prowess and test operation capabilities that Innospace has accumulated over a long period of time, while also showing that we have entered the final stage for commercial launch. Currently, all executives and staff are doing their best to successfully complete the first stage certification test, which is the final gateway for launch, and we will make every effort to prepare for a smooth commercial launch in the second half of the year.”

Two companies forge unlikely alliance in Dubai. Two German entrepreneurs have joined forces with a team of Russian expats steeped in space history to design a rocket using computational AI models, Payload reports. The “strategic partnership” is between LEAP 71, an AI-enabled design startup, and Aspire Space, a company founded by the son of a Soviet engineer who was in charge of launching Zenit rockets from the Baikonur Cosmodrome in Kazakhstan in the 1980s. The companies will base their operations in Dubai. The unlikely pairing aims to develop a new large reusable launch vehicle capable of delivering up to 15 metric tons to low-Earth orbit. Aspire Space is a particularly interesting company if you’re a space history enthusiast. Apart from the connections of Aspire’s founder to Soviet space history, Aspire’s chief technology officer, Sergey Sopov, started his career at Baikonur working on the Energia heavy-lift rocket and Buran space shuttle, before becoming an executive at Sea Launch later in his career.

Trust the computer … It’s easy to be skeptical about this project, but it has attracted an interesting group of people. LEAP 71 has just two employees—its two German co-founders—but boasts lofty ambitions and calls itself a “pioneer in AI-driven engineering.” As part of the agreement with Aspire Space, LEAP 71 will use a proprietary software program called Noyron to design the entire propulsion stack for Aspire’s rockets. The company says its AI-enabled design approach for Aspire’s 450,000-pound-thrust engine will cut in half the time it took other rocket companies to begin test-firing a new engine of similar size. Rudenko forecasts Aspire’s entire project, including a launcher, reusable spacecraft, and ground infrastructure to support it all, will cost more than $1 billion. So far, the project is self-funded, Rudenko told Payload. (submitted by Lin Kayser)

Russia launches ISS resupply freighter. A Russian Progress supply ship launched July 3 from the Baikonur Cosmodrome in Kazakhstan atop a Soyuz-2.1a rocket, NASASpaceflight reports. Packed with 5,787 pounds (2,625 kilograms) of cargo and fuel, the Progress MS-31 spacecraft glided to an automated docking at the International Space Station two days later. The Russian cosmonauts living aboard the ISS will unpack the supplies carried inside the Progress craft’s pressurized compartment. This was the eighth orbital launch of the year by a Russian rocket, continuing a downward trend in launch activity for the Russian space program in recent years.

Celebrating a golden anniversary … The Soyuz rocket that launched Progress MS-31 was painted an unusual blue and white scheme, as it was originally intended for a commercial launch that was likely canceled after Russia’s invasion of Ukraine. It also sported a logo commemorating the 50th anniversary of the Apollo-Soyuz mission in July 1975.

Chinese rocket moves closer to first launch. Chinese commercial launch firm Orienspace is aiming for a late 2025 debut of its Gravity-2 rocket following a recent first-stage engine hot fire test, Space News reports. The “three-in-one” hot fire test verified the performance of the Gravity-2 rocket’s first stage engine, servo mechanisms, and valves that regulate the flow of propellants into the engine, according to a press release from Orienspace. The Gravity-2 rocket’s recoverable and reusable first stage will be powered by nine of these kerosene-fueled engines. The recent hot fire test “lays a solid foundation” for future tests leading up to the Gravity-2’s inaugural flight.

Extra medium … Orienspace’s first rocket, the solid-fueled Gravity-1, completed its first successful flight last year to place multiple small satellites into orbit. Gravity-2 is a much larger vehicle, standing 230 feet (70 meters) tall, the same height as SpaceX’s Falcon 9 rocket. Orienspace’s new rocket will fly in a core-only configuration or with the assistance of two solid rocket boosters. An infographic released by Orienspace in conjunction with the recent engine hot fire test indicates the Gravity-2 rocket will be capable of hauling up to 21.5 metric tons (47,400 pounds) of cargo into low-Earth orbit, placing its performance near the upper limit of medium-lift launchers.

Senator calls out Texas for trying to steal space shuttle. A political effort to remove space shuttle Discovery from the Smithsonian and place it on display in Texas encountered some pushback on Thursday, as a US senator questioned the expense of carrying out what he described as a theft, Ars reports. “This is not a transfer. It’s a heist,” said Sen. Dick Durbin (D-Ill.) during a budget markup hearing before the Senate Appropriations Committee. “A heist by Texas because they lost a competition 12 years ago.” In April, Republican Sens. John Cornyn and Ted Cruz, both representing Texas, introduced the “Bring the Space Shuttle Home Act” that called for Discovery to be relocated from the National Air and Space Museum’s Steven F. Udvar-Hazy Center in northern Virginia and displayed at Space Center Houston. They then inserted an $85 million provision for the shuttle relocation into the Senate version of the “One Big Beautiful Bill,” which, to comply with Senate rules, was more vaguely worded but was meant to achieve the same goal. That bill was enacted on July 4, when President Donald Trump signed it into law.

Dollar signs … As ridiculous as it is to imagine spending $85 million on moving a space shuttle from one museum to another, it’ll actually cost a lot more to do it safely. Citing research by NASA and the Smithsonian, Durbin said that the total was closer to $305 million, and that did not include the estimated $178 million needed to build a facility to house and display Discovery once it was in Houston. Furthermore, it was unclear if Congress even has the right to remove an artifact, let alone a space shuttle, from the Smithsonian’s collection. The Washington, DC, institution, which serves as a trust instrumentality of the US, maintains that it owns Discovery. The paperwork signed by NASA in 2012 transferred “all rights, interest, title, and ownership” for the spacecraft to the Smithsonian. “This will be the first time ever in the history of the Smithsonian someone has taken one of their displays and forcibly taken possession of it. What are we doing here? They don’t have the right in Texas to claim this,” said Durbin.

Starbase keeps getting bigger. Cameron County, Texas, has given SpaceX the green light to build an air separator facility, which will be located less than 300 feet from the region’s sand dunes, frustrating locals concerned about the impact on vegetation and wildlife, the Texas Tribune reports. The commissioners voted 3–1 to give Elon Musk’s rocket company a beachfront construction certificate and dune protection permit, allowing the company to build a facility to produce gases needed for Starship launches. The factory will separate air into nitrogen and oxygen. SpaceX uses liquid oxygen as a propellant and liquid nitrogen for testing and operations.

Saving the roads … By having the facility on site, SpaceX hopes to make the delivery of those gases more efficient by eliminating the need to have dozens of trucks deliver them from Brownsville. The company says they need more than 200 trucks of liquid nitrogen and oxygen delivered for each launch, a SpaceX engineer told the county during a meeting last week. With their application, SpaceX submitted a plan to mitigate expected negative effects on 865 square feet of dune vegetation and 20 cubic yards of dunes, as well as compensate for expected permanent impacts to 7,735 square feet of dune vegetation and 465 cubic yards of dunes. While the project will be built on property owned by SpaceX, the county holds the authority to manage the construction that affects Boca Chica’s dunes.

ULA is stacking its third Vulcan rocket. A little more than a week after its most recent Atlas V rocket launch, United Launch Alliance rolled a Vulcan booster to the Vertical Integration Facility at Cape Canaveral Space Force Station in Florida on July 2 to begin stacking its first post-certification Vulcan rocket, Spaceflight Now reports. The operation, referred to by ULA as Launch Vehicle on Stand (LVOS), is the first major milestone toward the launch of the third Vulcan rocket. The upcoming launch will be the first operational flight of ULA’s new rocket with a pair of US military payloads, following two certification flights in 2024.

For the second time … This is the second time that this particular Vulcan booster was brought to Space Launch Complex 41 in anticipation of a launch campaign. It was previously readied in late October of last year in support of the USSF-106 mission, the Space Force’s designation for the first national security launch to use the Vulcan rocket. However, plans changed as the process of certifying Vulcan to fly government payloads took longer than expected, and ULA pivoted to launch two Atlas V rockets on commercial missions from the same pad before switching back to Vulcan launch preps.

Progress report on China’s Moon rocket. China’s self-imposed deadline of landing astronauts on the Moon by 2030 is now just five years away, and we’re starting to see some tangible progress. Construction of the launch pad for the Long March 10 rocket, the massive vehicle China will use to launch its first crews toward the Moon, is well along at the Wenchang Space Launch Site on Hainan Island. An image shared on the Chinese social media platform Weibo, and then reposted on X, shows the Long March 10’s launch tower near its final height. A mobile launch platform presumably for the Long March 10 is under construction nearby.

Super heavy … The Long March 10 will be China’s most powerful rocket to date, with the ability to dispatch 27 metric tons of payload toward the Moon, a number comparable to NASA’s Space Launch System. Designed for partial reusability, the Long March 10 will use an all-liquid propulsion system and stand more than 92 meters (300 feet) tall. The rocket will launch Chinese astronauts inside the nation’s next-generation Mengzhou crew capsule, along with a lunar lander to transport crew members from lunar orbit to the surface of the Moon using an architecture similar to NASA’s Apollo program.

Pentagon may put SpaceX at the center of a sensor-to-shooter targeting network

milnet, Science, Space, space development agency, space force, spacex, starlink, starshield / Mike M. / July 2, 2025

Under this plan, SpaceX’s satellites would play a big role in the Space Force’s kill chain.

The Trump administration plans to cancel a fleet of orbiting data relay satellites managed by the Space Development Agency and replace it with a secretive network that, so far, relies primarily on SpaceX’s Starlink Internet constellation, according to budget documents.

The move prompted questions from lawmakers during a Senate hearing on the Space Force’s budget last week. While details of the Pentagon’s plan remain secret, the White House proposal would commit $277 million in funding to kick off a new program called “pLEO SATCOM” or “MILNET.”

The funding line for a proliferated low-Earth orbit satellite communications network hasn’t appeared in a Pentagon budget before, but plans for MILNET already exist in a different form. Meanwhile, the budget proposal for fiscal year 2026 would eliminate funding for a new tranche of data relay satellites from the Space Development Agency. The pLEO SATCOM or MILNET program would replace them, providing crucial support for the Trump administration’s proposed Golden Dome missile defense shield.

“We have to look at what are the other avenues to deliver potentially a commercial proliferated low-Earth orbit constellation,” Gen. Chance Saltzman, chief of space operations, told senators last week. “So, we are simply looking at alternatives as we look to the future as to what’s the best way to scale this up to the larger requirements for data transport.”

What will these satellites do?

For six years, the Space Development Agency’s core mission has been to provide the military with a more resilient, more capable network of missile tracking and data relay platforms in low-Earth orbit. Those would augment the Pentagon’s legacy fleet of large, billion-dollar missile warning satellites that are parked more than 20,000 miles away in geostationary orbit.

These satellites detect the heat plumes from missile launches—and also large explosions and wildfires—to provide an early warning of an attack. The US Space Force’s early warning satellites were critical in allowing interceptors to take out Iranian ballistic missiles launched toward Israel last month.

Experts say there are good reasons for the SDA’s efforts. One motivation was the realization over the last decade or so that a handful of expensive spacecraft make attractive targets for an anti-satellite attack. It’s harder for a potential military adversary to go after a fleet of hundreds of smaller satellites. And if they do take out a few of these lower-cost satellites, it’s easier to replace them with little impact on US military operations.

Missile-tracking satellites in low-Earth orbit, flying at altitudes of just a few hundred miles, are also closer to the objects they are designed to track, meaning their infrared sensors can detect and locate dimmer heat signatures from smaller projectiles, such as hypersonic missiles.

But tracking the missiles isn’t enough. The data must reach the ground in order to be useful. The SDA’s architecture includes a separate fleet of small communications satellites to relay data from the missile tracking network, and potentially surveillance spacecraft tracking other kinds of moving targets, to military forces on land, at sea, or in the air through a series of inter-satellite laser crosslinks.

The military refers to this data relay component as the transport layer. When it was established in the first Trump administration, the SDA set out to deploy tranches of tracking and data transport satellites. Each new tranche would come online every couple of years, allowing the Pentagon to tap into new technologies as fast as industry develops them.

The SDA launched 27 so-called “Tranche 0” satellites in 2023 to demonstrate the concept’s overall viability. The first batch of more than 150 operational SDA satellites, called Tranche 1, is due to begin launching later this year. The SDA plans to begin deploying more than 250 Tranche 2 satellites in 2027. Another set of satellites, Tranche 3, would have followed a couple of years later. Now, the Pentagon seeks to cancel the Tranche 3 transport layer, while retaining the Tranche 3 tracking layer under the umbrella of the Space Development Agency.

Out of the shadows

While SpaceX’s role isn’t mentioned explicitly in the Pentagon’s budget documents, the MILNET program is already on the books, and SpaceX is the lead contractor. It has been made public in recent months, after years of secrecy, although many details remain unclear. Managed in a partnership between the Space Force and the National Reconnaissance Office (NRO), MILNET is designed to use military-grade versions of Starlink Internet satellites to create a “hybrid mesh network” the military can rely on for a wide range of applications.

The military version of the Starlink platform is called Starshield. SpaceX has already launched nearly 200 Starshield satellites for the NRO, which uses them for intelligence, surveillance, and reconnaissance missions.

At an industry conference last month, the Space Force commander in charge of operating the military’s communications satellites revealed new information about MILNET, according to a report by Breaking Defense. The network uses SpaceX-made user terminals with additional encryption to connect with Starshield satellites in orbit.

Col. Jeff Weisler, commander of a Space Force unit called Delta 8, said MILNET will comprise some 480 satellites operated by SpaceX but overseen by a military mission director “who communicates to the contracted workforce to execute operations at the timing and tempo of warfighting.”

The Space Force has separate contracts with SpaceX to use the commercial Starlink service. MILNET’s dedicated constellation of more secure Starshield satellites is separate from Starlink, which now has more 7,000 satellites in space.

“We are completely relooking at how we’re going to operate that constellation of capabilities for the joint force, which is going to be significant because we’ve never had a DoD hybrid mesh network at LEO,” Weisler said last month.

So, the Pentagon already relies on SpaceX’s communication services, not to mention the company’s position as the leading launch provider for Space Force and NRO satellites. With MILNET’s new role as a potential replacement for the Space Development Agency’s data relay network, SpaceX’s satellites would become a cog in combat operations.

The data transport layer, whether it’s SDA’s architecture or a commercial solution like Starshield, will “underpin” the Pentagon’s planned Golden Dome missile defense system, Saltzman said.

But it’s not just missiles. Data relay satellites in low-Earth orbit will also have a part in the Space Force’s initiatives to develop space-based platforms to track moving targets on the ground and in the air. Eventually, all Space Force satellites could have the ability to plug into MILNET to send their data to the ground.

A spokesperson for the Department of the Air Force, which includes the Space Force, told Air & Space Forces Magazine that the pLEO, or MILNET, constellation “will provide global, integrated, and resilient capabilities across the combat power, global mission data transport, and satellite communications mission areas.”

That all adds up to a lot of bits and bytes, and the Space Force’s need for data backhaul is only going to increase, according to Col. Robert Davis, head of the Space Sensing Directorate at Space Systems Command.

He said the SDA’s satellites will use onboard edge processing to create two-dimensional missile track solutions. Eventually, the SDA’s satellites will be capable of 3D data fusion with enough fidelity to generate a full targeting solution that could be transmitted directly to a weapons system for it to take action without needing any additional data processing on the ground.

“I think the compute [capability] is there,” Davis said Tuesday at an event hosted by the Mitchell Institute, an aerospace-focused think tank in Washington, DC. “Now, it’s a comm[unication] problem and some other technical integration challenges. But how do I do that 3D fusion on orbit? If I do 3D fusion on orbit, what does that allow me to do? How do I get low-latency comms to the shooter or to a weapon itself that’s in flight? So you can imagine the possibilities there.”

The possibilities include exploiting automation, artificial intelligence, and machine learning to sense, target, and strike an enemy vehicle—a truck, tank, airplane, ship, or missile—nearly instantaneously.

“If I’m on the edge doing 3D fusion, I’m less dependent on the ground and I can get around the globe with my mesh network,” Davis said. “There’s inherent resilience in the overall architecture—not just the space architecture, but the overall architecture—if the ground segment or link segment comes under attack.”

Questioning the plan

Military officials haven’t disclosed the cost of MILNET, either in its current form or in the future architecture envisioned by the Trump administration. For context, SDA has awarded fixed-price contracts worth more than $5.6 billion for approximately 340 data relay satellites in Tranches 1 and 2.

That comes out to roughly $16 million per spacecraft, at least an order of magnitude more expensive than a Starlink satellite coming off of SpaceX’s assembly line. Starshield satellites, with their secure communications capability, are presumably somewhat more expensive than an off-the-shelf Starlink.

Some former defense officials and lawmakers are uncomfortable with putting commercially operated satellites in the “kill chain,” the term military officials use for the process of identifying threats, making a targeting decision, and taking military action.

It isn’t clear yet whether SpaceX will operate the MILNET satellites in this new paradigm, but the company has a longstanding preference for doing so. SpaceX built a handful of tech demo satellites for the Space Development Agency a few years ago, but didn’t compete for subsequent SDA contracts. One reason for this, sources told Ars, is that the SDA operates its satellite constellation from government-run control centers.

Instead, the SDA chose L3Harris, Lockheed Martin, Northrop Grumman, Rocket Lab, Sierra Space, Terran Orbital, and York Space Systems to provide the next batches of missile tracking and data transport satellites. RTX, formerly known as Raytheon, withdrew from a contract after the company determined it couldn’t make money on the program.

The tracking satellites will carry different types of infrared sensors, some with wide fields of view to detect missile launches as they happen, and others with narrow-angle sensors to maintain custody of projectiles in flight. The data relay satellites will employ different frequencies and anti-jam waveforms to supply encrypted data to military forces on the ground.

The Space Development Agency’s path hasn’t been free of problems. The companies the agency selected to build its spacecraft have faced delays, largely due to supply chain issues, and some government officials have worried the Army, Navy, Air Force, and Marine Corps aren’t ready to fully capitalize on the information streaming down from the SDA’s satellites.

The SDA hired SAIC, a government services firm, earlier this year with a $55 million deal to act as a program integrator with responsibility to bring together satellites from multiple contractors, keep them on schedule, and ensure they provide useful information once they’re in space.

SpaceX, on the other hand, is a vertically integrated company. It designs, builds, and launches its own Starlink and Starshield satellites. The only major components of SpaceX’s spy constellation for the NRO that the company doesn’t build in-house are the surveillance sensors, which come from Northrop Grumman.

Buying a service from SpaceX might save money and reduce the chances of further delays. But lawmakers argued there’s a risk in relying on a single company for something that could make or break real-time battlefield operations.

Sen. Chris Coons (D-Del.), ranking member of the Senate Appropriations Subcommittee on Defense, raised concerns that the Space Force is canceling a program with “robust competition and open standards” and replacing it with a network that is “sole-sourced to SpaceX.”

“This is a massive and important contract,” Coons said. “Doesn’t handing this to SpaceX make us dependent on their proprietary technology and avoid the very positive benefits of competition and open architecture?”

Later in the hearing, Sen. John Hoeven (R-N.D.) chimed in with his own warning about the Space Force’s dependence on contractors. Hoeven’s state is home to one of the SDA’s satellite control centers.

“We depend on the Air Force, the Space Force, the Department of Defense, and the other services, and we can’t be dependent on private enterprise when it comes to fighting a war, right? Would you agree with that?” Hoeven asked Saltzman.

“Absolutely, we can’t be dependent on it,” Saltzman replied.

Air Force Secretary Troy Meink said military officials haven’t settled on a procurement strategy. He didn’t mention SpaceX by name.

As we go forward, MILNET, the term, should not be taken as just a system,” Meink said. “How we field that going forward into the future is something that’s still under consideration, and we will look at the acquisition of that.”

An Air Force spokesperson confirmed the requirements and architecture for MILNET are still in development, according to Air & Space Forces Magazine. The spokesperson added that the department is “investigating” how to scale MILNET into a “multi-vendor satellite communication architecture that avoids vendor lock.”

This doesn’t sound all that different than the SDA’s existing technical approach for data relay, but it shifts more responsibility to commercial companies. While there’s still a lot we don’t know, contractors with existing mega-constellations would appear to have an advantage in winning big bucks under the Pentagon’s new plan.

There are other commercial low-Earth orbit constellations coming online, such as Amazon’s Project Kuiper broadband network, that could play a part in MILNET. However, if the Space Force is looking for a turnkey commercial solution, Starlink and Starshield are the only options available today, putting SpaceX in a strong position for a massive windfall.

Rocket Report: SpaceX’s dustup on the border; Northrop has a nozzle problem

launch, NASA, rocket report, Science, Space, spacex / Shannon Garcia / June 27, 2025

NASA has finally test-fired the first of its new $100 million SLS rocket engines.

Welcome to Edition 7.50 of the Rocket Report! We’re nearly halfway through the year, and it seems like a good time to look back on the past six months. What has been most surprising to me in the world of rockets? First, I didn’t expect SpaceX to have this much trouble with Starship Version 2. Growing pains are normal for new rockets, but I expected the next big hurdles for SpaceX to clear with Starship to be catching the ship from orbit and orbital refueling, not completing a successful launch. The state of Blue Origin’s New Glenn program is a little surprising to me. New Glenn’s first launch in January went remarkably well, beating the odds for a new rocket. Now, production delays are pushing back the next New Glenn flights. The flight of Honda’s reusable rocket hopper also came out of nowhere a few weeks ago.

Isar raises 150 million euros. German space startup Isar Aerospace has obtained 150 million euros ($175 million) in funding from an American investment company, Reuters reports. The company, which specializes in satellite launch services, signed an agreement for a convertible bond with Eldridge Industries, it said. Isar says it will use the funding to expand its launch service offerings. Isar’s main product is the Spectrum rocket, a two-stage vehicle designed to loft up to a metric ton (2,200 pounds) of payload mass to low-Earth orbit. Spectrum flew for the first time in March, but it failed moments after liftoff and fell back to the ground near its launch pad. Still, Isar became the first in a new crop of European launch startups to launch a rocket theoretically capable of reaching orbit.

Flush with cash … Isar is leading in another metric, too. The Munich-based company has now raised more than 550 million euros ($642 million) from venture capital investors and government-backed funds. This far exceeds the fundraising achievements of any other European launch startup. But the money will only go so far before Isar must prove it can successfully launch a rocket into orbit. Company officials have said they aim to launch the second Spectrum rocket before the end of this year. (submitted by EllPeaTea)

Rocket Lab aiming for record turnaround. Rocket Lab demonstrated a notable degree of flexibility this week. Two light-class Electron rockets were nearing launch readiness at the company’s privately owned spaceport in New Zealand, but one of the missions encountered a technical problem, and Rocket Lab scrubbed a launch attempt Tuesday. The spaceport has two launch pads next to one another, so while technicians worked to fix that problem, Rocket Lab slotted in another Electron rocket to lift off from the pad next door. That mission, carrying a quartet of small commercial signals intelligence satellites for HawkEye 360, successfully launched Thursday.

Giving it another go … A couple of hours after that launch, Rocket Lab announced it was ready to try again with the mission it had grounded earlier in the week. “Can’t get enough of Electron missions? How about another one tomorrow? With our 67th mission complete, we’ve scheduled our next launch from LC-1 in less than 48 hours—Electron’s fastest turnaround from the same launch site yet!” Rocket Lab hasn’t disclosed what satellite is flying on this mission, citing the customer’s preference to remain anonymous for now.

You guessed it! Baguette One will launch from France. French rocket builder HyPrSpace will launch its Baguette One demonstrator from a missile testing site in mainland France, after signing an agreement with the country’s defense procurement agency, European Spaceflight reports. HyPrSpace was founded in 2019 to begin designing an orbital-class rocket named Orbital Baguette 1 (OB-1). The Baguette One vehicle is a subscale, single-stage suborbital demonstrator to prove out technologies for the larger satellite launcher, mainly its hybrid propulsion system.

Sovereign launch … HyPrSpace’s Baguette One will stand roughly 10 meters (30 feet) tall and will be capable of carrying payloads of up to 300 kilograms (660 pounds) to suborbital space. It is scheduled to launch next year from a French missile testing site in the south of France. “Gaining access to this dual-use launch pad in mainland France is a major achievement after many years of work on our hybrid propulsion technology,” said Sylvain Bataillard, director general of HyPrSpace. “It’s a unique opportunity for HyPrSpace and marks a decisive turning point. We’re eager to launch Baguette One and to play a key role in building a more sovereign, more sustainable, and boldly innovative European dual-use space industry.” (submitted by EllPeaTea)

Firefly moves closer to launching from Sweden. An agreement between the United States and Sweden brings Firefly Aerospace one step closer to launching its Alpha rocket from a Swedish spaceport, Space News reports. The two countries signed a technology safeguards agreement (TSA) at a June 20 ceremony at the Swedish embassy in Washington, DC. The TSA allows the export of American rockets to Sweden for launches there, putting in place measures to protect launch vehicle technology.

A special relationship … The US government has signed launch-related safeguard agreements with only a handful of countries, such as Australia, the United Kingdom, and now Sweden. Rocket exports are subject to strict controls because of the potential military applications of that technology. Firefly currently launches its Alpha rocket from Vandenberg Space Force Base, California, and is building a launch site at Wallops Island, Virginia. Firefly also has a lease for a launch pad at Cape Canaveral, Florida, although the company is prioritizing other sites. Then, last year, Firefly announced an agreement with the Swedish Space Corporation to launch Alpha from Esrange Space Center as soon as 2026. (submitted by EllPeaTea)

Amazon is running strong out of the gate. For the second time in two months, United Launch Alliance sent a batch of 27 broadband Internet satellites into orbit for Amazon on Monday morning, Ars reports. This was the second launch of a full load of operational satellites for Amazon’s Project Kuiper, a network envisioned to become a competitor to SpaceX’s Starlink. Just like the last flight on April 28, an Atlas V rocket lifted off from Cape Canaveral, Florida, and delivered Amazon’s satellites into an on-target orbit roughly 280 miles (450 kilometers) above Earth.

Time to put up or shut up … After lengthy production delays at Amazon’s satellite factory, the retail giant is finally churning out Kuiper satellites at scale. Amazon has already shipped the third batch of Kuiper satellites to Florida to prepare for launch on a SpaceX Falcon 9 rocket next month. ULA won the lion’s share of Amazon’s multibillion-dollar launch contract in 2022, committing to up to 38 Vulcan launches for Kuiper and nine Atlas V flights. Three of those Atlas Vs have now launched. Amazon also reserved 18 launches on Europe’s Ariane 6 rocket, and at least 12 on Blue Origin’s New Glenn. Vulcan, Ariane 6, and New Glenn have only flown one or two times, and Amazon is asking them to quickly ramp up their cadence to deliver 3,232 Kuiper satellites to orbit in the next few years. The handful of Falcon 9s and Atlas Vs that Amazon has on contract are the only rockets in the bunch with a proven track record. With Kuiper satellites now regularly shipping out of the factory, any blame for future delays may shift from Amazon to the relatively unproven rockets it has chosen to launch them.

Falcon 9 launches with four commercial astronauts. Retired astronaut Peggy Whitson, America’s most experienced space flier, and three rookie crewmates from India, Poland, and Hungary blasted off on a privately financed flight to the International Space Station early Wednesday, CBS News reports. This is the fourth non-government mission mounted by Houston-based Axiom Space. The four commercial astronauts rocketed into orbit on a SpaceX Falcon 9 launcher from NASA’s Kennedy Space Center in Florida, and their Dragon capsule docked at the space station Thursday to kick off a two-week stay.

A brand-new Dragon … The Crew Dragon spacecraft flown on this mission, serial number C213, is the fifth and final addition to SpaceX’s fleet of astronaut ferry ships built for NASA trips to the space station and for privately funded commercial missions to low-Earth orbit. Moments after reaching orbit Wednesday, Whitson revealed the name of the new spacecraft: Crew Dragon Grace. “We had an incredible ride uphill, and now we’d like to set our course for the International Space Station aboard the newest member of the Dragon fleet, our spacecraft named Grace. … Grace reminds us that spaceflight is not just a feat of engineering, but an act of goodwill to the benefit of every human everywhere.”

How soon until Ariane 6 is flying regularly? It’ll take several years for Arianespace to ramp up the launch cadence of Europe’s new Ariane 6 rocket, Space News reports. David Cavaillolès, chief executive of Arianespace, addressed questions at the Paris Air Show about how quickly Arianespace can reach its target of launching 10 Ariane 6 rockets per year. “We need to go to 10 launches per year for Ariane 6 as soon as possible,” he said. “It’s twice as more as for Ariane 5, so it’s a big industrial change.” Two Ariane 6 rockets have launched so far, and a third mission is on track to lift off in August. Arianespace’s CEO reiterated earlier plans to conduct four more Ariane 6 launches through the end of this year, including the first flight of the more powerful Ariane 64 variant with four solid rocket boosters.

Not a heavy lift … Arianespace’s target flight rate of 10 Ariane 6 rockets per year is modest compared to other established companies with similarly sized launch vehicles. United Launch Alliance is seeking to launch as many as 25 Vulcan rockets per year. Blue Origin’s New Glenn is designed to eventually fly often, although the company hasn’t released a target launch cadence. SpaceX, meanwhile, aims to launch up to 170 Falcon 9 rockets this year. But European governments are perhaps more committed than ever to maintaining a sovereign launch capability for the continent, so Ariane 6 isn’t going away. Arianespace has sold more than 30 Ariane 6 launches, primarily to European institutional customers and Amazon.

SLS booster blows its nozzle. NASA and Northrop Grumman test-fired a new solid rocket booster in Utah on Thursday, and it didn’t go exactly according to plan, Ars reports. This booster features a new design that NASA would use to power Space Launch System rockets, beginning with the ninth mission, or Artemis IX. The motor tested on Thursday isn’t flight-worthy. It’s a test unit that engineers will use to learn about the rocket’s performance. It turns out they did learn something, but perhaps not what they wanted. About 1 minute and 40 seconds into the booster’s burn, a fiery plume emerged from the motor’s structure just above its nozzle. Moments later, the nozzle violently disintegrated. The booster kept firing until it ran out of pre-packed solid propellant.

A questionable future … NASA’s Space Launch System appears to have a finite shelf life. The Trump administration wants to cancel it after just three launches, while the preliminary text of a bill making its way through Congress would extend it to five flights. But chances are low the Space Launch System will make it to nine flights, and if it does, it’s questionable if it would reach that point before 2040. The SLS rocket is a core piece of NASA’s plan to return US astronauts to the Moon under the Artemis program, but the White House seeks to cancel the program in favor of cheaper commercial alternatives.

NASA conducts a low-key RS-25 engine test. The booster ground test on Thursday was the second time in less than a week that NASA test-fired new propulsion hardware for the Space Launch System. Last Friday, June 20, NASA ignited a new RS-25 engine on a test stand at Stennis Space Center in Mississippi. The hydrogen-fueled engine is the first of its kind to be manufactured since the end of the space shuttle program. This particular RS-25 engine is assigned to power the fifth launch of the SLS rocket, a mission known as Artemis V, that may end up never flying. While NASA typically livestreams engine tests at Stennis, the agency didn’t publicize this event ahead of time.

It has been 10 years … The SLS rocket was designed to recycle leftover parts from the space shuttle program, but NASA will run out of RS-25 engines after the rocket’s fourth flight and will exhaust its inventory of solid rocket booster casings after the eighth flight. Recognizing that shuttle-era parts will eventually run out, NASA signed a contract with Aerojet Rocketdyne (now L3Harris) to set the stage for the production of new RS-25 engines in 2015. NASA later ordered an initial batch of six RS-25 engines from Aerojet, then added 18 more to the order in 2020, at a price of about $100 million per engine. Finally, a brand-new flight-worthy RS-25 engine has fired up on a test stand. If the Trump administration gets its way, these engines will never fly. Maybe that’s fine, but after so long with so much taxpayer investment, last week’s test milestone is worth publicizing, if not celebrating.

SpaceX finds itself in a dustup on the border. President Claudia Sheinbaum of Mexico is considering taking legal action after one of SpaceX’s giant Starship rockets disintegrated in a giant fireball earlier this month as it was being fueled for a test-firing of its engines, The New York Times reports. No one was injured in the explosion, which rained debris on the beaches of the northern Mexican state of Tamaulipas. The conflagration occurred at a test site SpaceX operates a few miles away from the Starship launch pad. This test facility is located next to the Rio Grande River, just a few hundred feet from Mexico. The power of the blast sent wreckage flying across the river into Mexican territory.

Collision course …“We are reviewing everything related to the launching of rockets that are very close to our border,” Sheinbaum said at a news conference Wednesday. If SpaceX violated any international laws, she added, “we will file any necessary claims.” Sheinbaum’s leftist party holds enormous sway around Mexico, and the Times reports she was responding to calls to take action against SpaceX amid a growing outcry among scientists, regional officials, and environmental activists over the impact that the company’s operations are having on Mexican ecosystems. SpaceX, on the other hand, said its efforts to recover debris from the Starship explosion have been “hindered by unauthorized parties trespassing on private property.” SpaceX said it requested assistance from the government of Mexico in the recovery and added that it offered its own resources to help with the cleanup.

SpaceX’s next Starship rocket exploded during a ground test in South Texas late Wednesday, dealing another blow to a program already struggling to overcome three consecutive failures in recent months.

The late-night explosion at SpaceX’s rocket development complex in Starbase, Texas, destroyed the bullet-shaped upper stage that was slated to launch on the next Starship test flight. The powerful blast set off fires around SpaceX’s Massey’s Test Site, located a few miles from the company’s Starship factory and launch pads.

Live streaming video from NASASpaceflight.com and LabPadre—media organizations with cameras positioned around Starbase—showed the 15-story-tall rocket burst into flames shortly after 11: 00 pm local time (12: 00 am EDT; 04: 00 UTC). Local residents as far as 30 miles away reported seeing and feeling the blast.

SpaceX confirmed the Starship, numbered Ship 36 in the company’s inventory, “experienced a major anomaly” on a test stand as the vehicle prepared to ignite its six Raptor engines for a static fire test. These hold-down test-firings are typically one of the final milestones in a Starship launch campaign before SpaceX moves the rocket to the launch pad.

The explosion occurred as SpaceX finished up loading super-cold methane and liquid oxygen propellants into Starship in preparation for the static fire test. The company said the area around the test site was evacuated of all personnel, and everyone was safe and accounted for after the incident. Firefighters from the Brownsville Fire Department were dispatched to the scene.

“Our Starbase team is actively working to safe the test site and the immediate surrounding area in conjunction with local officials,” SpaceX posted on X. “There are no hazards to residents in surrounding communities, and we ask that individuals do not attempt to approach the area while safing operations continue.”

Picking up the pieces

Earlier Wednesday, just hours before the late-night explosion at Starbase, an advisory released by the Federal Aviation Administration showed SpaceX had set June 29 as a tentative launch date for the next Starship test flight. That won’t happen now, and it’s anyone’s guess when SpaceX will have another Starship ready to fly.

Massey’s Test Site, named for a gun range that once occupied the property, is situated on a bend in the Rio Grande River, just a few hundred feet from the Mexican border. The test site is currently the only place where SpaceX can put Starships through proof testing and static fire tests before declaring the rockets are ready to fly.

The extent of the damage to ground equipment at Massey’s was not immediately clear, so it’s too soon to say how long the test site will be out of commission. For now, though, the explosion leaves SpaceX without a facility to support preflight testing on Starships.

The videos embedded below come from NASASpaceflight.com and LabPadre, showing multiple angles of the Starship blast.

The explosion at Massey’s is a reminder of SpaceX’s rocky path to get Starship to this point in its development. In 2020 and 2021, SpaceX lost several Starship prototypes to problems during ground and flight testing. The visual of Ship 36 going up in flames harkens back to those previous explosions, along with the fiery demise of a Falcon 9 rocket on its launch pad in 2016 under circumstances similar to Wednesday night’s incident.

SpaceX has now launched nine full-scale Starship rockets since April 2023, and before the explosion, the company hoped to launch the 10th test flight later this month. Starship’s track record has been dreadful so far this year, with the rocket’s three most recent test flights ending prematurely. These setbacks followed a triumphant 2024, when SpaceX made clear progress on each successive Starship suborbital test flight, culminating in the first catch of the rocket’s massive Super Heavy booster with giant robotic arms on the launch pad tower.

Stacked together, the Super Heavy booster stage and Starship upper stage stand more than 400 feet tall, creating the largest rocket ever built. SpaceX has already flown a reused Super Heavy booster, and the company has designed Starship itself to be recoverable and reusable, too.

After last year’s accomplishments, SpaceX appeared to be on track for a full orbital flight, an attempt to catch and recover Starship itself, and an important in-space refueling demonstration in 2025. The refueling demo has officially slipped into 2026, and it’s questionable whether SpaceX will make enough progress in the coming months to attempt recovery of a ship before the end of this year.

Ambition meets reality

SpaceX debuted an upgraded Starship design, called Version 2 or Block 2, on a test flight in January. It’s been one setback after another since then.

The new Starship design is slightly taller than the version of Starship that SpaceX flew in 2023 and 2024. It has an improved heat shield to better withstand the extreme heat of atmospheric reentry. SpaceX also installed a new fuel feed line system to route methane fuel to the ship’s Raptor engines, and an improved propulsion avionics module controlling the vehicle’s valves and reading sensors.

Despite—or perhaps because of—all of these changes for Starship Version 2, SpaceX has been unable to replicate the successes it achieved with Starship in the last two years. Ships launched on test flights in January and March spun out of control minutes after liftoff, scattering debris over the sea, and in at least one case, onto a car in the Turks and Caicos Islands.

SpaceX engineers concluded the January failure was likely caused by intense vibrations that triggered fuel leaks and fires in the ship’s engine compartment, causing an early shutdown of the rocket’s engines. Engineers said the vibrations were likely in resonance with the vehicle’s natural frequency, intensifying the shaking beyond the levels SpaceX predicted.

The March flight failed in similar fashion, but SpaceX’s investigators determined the most probable root cause was a hardware failure in one of the ship’s engines, a different failure mode than two months before.

During SpaceX’s most recent Starship test flight last month, the rocket completed the ascent phase of the mission as planned, seemingly overcoming the problems that plagued the prior two launches. But soon after the Raptor engines shut down, a fuel leak caused the ship to begin tumbling in space, preventing the vehicle from completing a guided reentry to test the performance of new heat shield materials.

SpaceX is working on a third-generation Starship design, called Version 3, that the company says could be ready to fly by the end of this year. The upgraded Starship Version 3 design will be able to lift heavier cargo—up to 200 metric tons—into orbit thanks to larger propellant tanks and more powerful Raptor engines. Version 3 will also have the ability to refuel in low-Earth orbit.

Version 3 will presumably have permanent fixes to the problems currently slowing SpaceX’s pace of Starship development. And there are myriad issues for SpaceX’s engineers to solve, from engine reliability and the ship’s resonant frequency, to beefing up the ship’s heat shield and fixing its balky payload bay door.

Once officials solve these problems, it will be time for SpaceX to bring a Starship from low-Earth orbit back to the ground. Then, there’s more cool stuff on the books, like orbital refueling and missions to the Moon in partnership with NASA’s Artemis program. NASA has contracts worth more than $4 billion with SpaceX to develop a human-rated Starship that can land astronauts on the Moon and launch them safely back into space.

The Trump administration’s proposed budget for NASA would cancel the Artemis program’s ultra-expensive Space Launch System rocket and Orion crew capsule after two more flights, leaving commercial heavy-lifters to take over launching astronauts from the Earth to the Moon. SpaceX’s Starship, already on contract with NASA as a human-rated lander, may eventually win more government contracts to fill the role of SLS and Orion under Trump’s proposed budget. Other rockets, such as Blue Origin’s New Glenn, are also well-positioned to play a larger role in human space exploration.

NASA’s official schedule for the first Artemis crew landing on the Moon puts the mission some time in 2027, using SLS and Orion to transport astronauts out to the vicinity of the Moon to meet up with SpaceX’s Starship lunar lander. After that mission, known as Artemis III, NASA would pivot to using commercial rockets from Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin to replace the Space Launch System.

Meanwhile, SpaceX’s founder and CEO has his sights set on Mars. Last month, Musk told his employees he wants to launch the first Starships toward the Red Planet in late 2026, when the positions of Earth and Mars in the Solar System make a direct journey possible. Optimistically, he would like to send people to Mars on Starships beginning in 2028.

All of these missions are predicated on SpaceX mastering routine Starship launch operations, rapid reuse of the ship and booster, and cryogenic refueling in orbit, along with adapting systems such as life support, communications, and deep space navigation for an interplanetary journey.

The to-do list is long for SpaceX’s Starship program—too long for Mars landings to seem realistic any time in the next few years. NASA’s schedule for the Artemis III lunar landing mission in 2027 is also tight, and not only because of Starship’s delays. The development of new spacesuits for astronauts to wear on the Moon may also put the Artemis III schedule at risk. NASA’s SLS rocket and Orion spacecraft have had significant delays throughout their history, so it’s not a sure thing they will be ready in 2027.

While it’s too soon to know the precise impact of Wednesday night’s explosion, we can say with some confidence that the chances of Starship meeting these audacious schedules are lower today than they were yesterday.
