The US Space Force announced Friday it selected SpaceX, United Launch Alliance, and Blue Origin for $13.7 billion in contracts to deliver the Pentagon’s most critical military to orbit into the early 2030s.

These missions will launch the government’s heaviest national security satellites, like the National Reconnaissance Office’s large bus-sized spy platforms, and deploy them into bespoke orbits. These types of launches often demand heavy-lift rockets with long-duration upper stages that can cruise through space for six or more hours.

The contracts awarded Friday are part of the next phase of the military’s space launch program once dominated by United Launch Alliance, the 50-50 joint venture between legacy defense contractors Boeing and Lockheed Martin.

After racking up a series of successful launches with its Falcon 9 rocket more than a decade ago, SpaceX sued the Air Force for the right to compete with ULA for the military’s most lucrative launch contracts. The Air Force relented in 2015 and allowed SpaceX to bid. Since then, SpaceX has won more than 40 percent of missions the Pentagon has ordered through the National Security Space Launch (NSSL) program, creating a relatively stable duopoly for the military’s launch needs.

The Space Force took over the responsibility for launch procurement from the Air Force after its creation in 2019. The next year, the Space Force signed another set of contracts with ULA and SpaceX for missions the military would order from 2020 through 2024. ULA’s new Vulcan rocket initially won 60 percent of these missions—known as NSSL Phase 2—but the Space Force reallocated a handful of launches to SpaceX after ULA encountered delays with Vulcan.

ULA’s Vulcan and SpaceX’s Falcon 9 and Falcon Heavy rockets will launch the remaining 42 Phase 2 missions over the next several years, then move on to Phase 3, which the Space Force announced Friday.

Spreading the wealth

This next round of Space Force launch contracts will flip the script, with SpaceX taking the lion’s share of the missions. The breakdown of the military’s new firm fixed-price launch agreements goes like this:

SpaceX will get 28 missions worth approximately $5.9 billion
ULA will get 19 missions worth approximately $5.4 billion
Blue Origin will get seven missions worth approximately

That equates to a 60-40 split between SpaceX and ULA for the bulk of the missions. Going into the competition, military officials set aside seven additional missions to launch with a third provider, allowing a new player to gain a foothold in the market. The Space Force reserves the right to reapportion missions between the three providers if one of them runs into trouble.

The Pentagon confirmed an unnamed fourth company also submitted a proposal, but wasn’t selected for Phase 3.

Rounded to the nearest million, the contract with SpaceX averages out to $212 million per launch. For ULA, it’s $282 million, and Blue Origin’s price is $341 million per launch. But take these numbers with caution. The contracts include a lot of bells and whistles, pricing them higher than what a commercial customer might pay.

According to the Pentagon, the contracts provide “launch services, mission unique services, mission acceleration, quick reaction/anomaly resolution, special studies, launch service support, fleet surveillance, and early integration studies/mission analysis.”

Essentially, the Space Force is paying a premium to all three launch providers for schedule priority, tailored solutions, and access to data from every flight of each company’s rocket, among other things.

“Winning 60% percent of the missions may sound generous, but the reality is that all SpaceX competitors combined cannot currently deliver the other 40%!,” Elon Musk, SpaceX’s founder and CEO, posted on X. “I hope they succeed, but they aren’t there yet.”

This is true if you look at each company’s flight rate. SpaceX has launched Falcon 9 and Falcon Heavy rockets 140 times over the last 365 days. These are the flight-proven rockets SpaceX will use for its share of Space Force missions.

ULA has logged four missions in the same period, but just one with the Vulcan rocket it will use for future Space Force launches. And Blue Origin, Jeff Bezos’s space company, launched the heavy-lift New Glenn rocket on its first test flight in January.

“We are proud that we have launched 100 national security space missions and honored to continue serving the nation with our new Vulcan rocket,” said Tory Bruno, ULA’s president and CEO, in a statement.

ULA used the Delta IV and Atlas V rockets for most of the missions it has launched for the Pentagon. The Delta IV rocket family is now retired, and ULA will end production of the Atlas V rocket later this year. Now, ULA’s Vulcan rocket will take over as the company’s sole launch vehicle to serve the Pentagon. ULA aims to eventually ramp up the Vulcan launch cadence to fly up to 25 times per year.

After two successful test flights, the Space Force formally certified the Vulcan rocket last week, clearing the way for ULA to start using it for military missions in the coming months. While SpaceX has a clear advantage in number of launches, schedule assurance, and pricing—and reliability comparable to ULA—Bruno has recently touted the Vulcan rocket’s ability to maneuver over long periods in space as a differentiator.

“This award constitutes the most complex missions required for national security space,” Bruno said in a ULA press release. “Vulcan continues to use the world’s highest energy upper stage: the Centaur V. Centaur V’s unmatched flexibility and extreme endurance enables the most complex orbital insertions continuing to advance our nation’s capabilities in space.”

Blue Origin’s New Glenn must fly at least one more successful mission before the Space Force will certify it for Lane 2 missions. The selection of Blue Origin on Friday suggests military officials believe New Glenn is on track for certification by late 2026.

“Honored to serve additional national security missions in the coming years and contribute to our nation’s assured access to space,” Dave Limp, Blue Origin’s CEO, wrote on X. “This is a great endorsement of New Glenn’s capabilities, and we are committed to meeting the heavy lift needs of our US DoD and intelligence agency customers.”

Navigating NSSL

There’s something you must understand about the way the military buys launch services. For this round of competition, the Space Force divided the NSSL program into two lanes.

Friday’s announcement covers Lane 2 for traditional military satellites that operate thousands of miles above the Earth. This bucket includes things like GPS navigation satellites, NRO surveillance and eavesdropping platforms, and strategic communications satellites built to survive a nuclear war. The Space Force has a low tolerance for failure with these missions. Therefore, the military requires rockets be certified before they can launch big-ticket satellites, each of which often cost hundreds of millions, and sometimes billions, of dollars.

The Space Force required all Lane 2 bidders to show their rockets could reach nine “reference orbits” with payloads of a specified mass. Some of the orbits are difficult to reach, requiring technology that only SpaceX and ULA have demonstrated in the United States. Blue Origin plans to do so on a future flight.

The higher orbits will require launches by “Lane 2” providers. Credit: Space Systems Command

The military projects to order 54 launches in Lane 2 from this year through 2029, with announcements each October of exactly which missions will go to each launch provider. This year, it will be just SpaceX and ULA. The Space Force said Blue Origin won’t be eligible for firm orders until next year. The missions would launch between 2027 and 2032.

“America leads the world in space launch, and through these NSSL Phase 3 Lane 2 contracts, we will ensure continued access to this vital domain,” said Maj. Gen. Stephen Purdy, Acting Assistant Secretary of the Air Force for Space Acquisition and Integration. “These awards bolster our ability to launch critical defense satellites while strengthening our industrial base and enhancing operational readiness.”

Lane 1 is primarily for missions to low-Earth orbit. These payloads include tech demos, experimental missions, and the military’s mega-constellation of missile tracking and data relay satellites managed by the Space Development Agency. For Lane 1 missions, the Space Force won’t levy the burdensome certification and oversight requirements it has long employed for national security launches. The Pentagon is willing to accept more risk with Lane 1, encompassing at least 30 missions through the end of the 2020s, in an effort to broaden the military’s portfolio of launch providers and boost competition.

Last June, Space Systems Command chose SpaceX, ULA, and Blue Origin for eligibility to compete for Lane 1 missions. SpaceX won all nine of the first batch of Lane 1 missions put up for bids. The military recently added Rocket Lab’s Neutron rocket and Stoke Space’s Nova rocket to the Lane 1 mix. Neither of those rockets have flown, and they will need at least one successful launch before approval to fly military payloads.

The Space Force has separate contract mechanisms for the military’s smallest satellites, which typically launch on SpaceX rideshare missions or dedicated launches with companies like Rocket Lab and Firefly Aerospace.

Military leaders like having all these options, and would like even more. If one launch provider or launch site is unavailable due to a technical problem—or, as some military officials now worry, an enemy attack—commanders want multiple backups in their toolkit. Market forces dictate that more competition should also lower prices.

“A robust and resilient space launch architecture is the foundation of both our economic prosperity and our national security,” said US Space Force Chief of Space Operations Gen. Chance Saltzman. “National Security Space Launch isn’t just a program; it’s a strategic necessity that delivers the critical space capabilities our warfighters depend on to fight and win.”

Welcome to Edition 7.37 of the Rocket Report! It’s been interesting to watch how quickly European officials have embraced ensuring they have a space launch capability independent of other countries. A few years ago, European government satellites regularly launched on Russian Soyuz rockets, and more recently on SpaceX Falcon 9 rockets from the United States. Russia is now non grata in European government circles, and the Trump administration is widening the trans-Atlantic rift. European leaders have cited the Trump administration and its close association with Elon Musk, CEO of SpaceX, as prime reasons to support sovereign access to space, a capability currently offered only by Arianespace. If European nations can reform how they treat their commercial space companies, there’s enough ambition, know-how, and money in Europe to foster a competitive launch industry.

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.

Isar Aerospace aims for weekend launch. A German startup named Isar Aerospace will try to launch its first rocket Saturday, aiming to become the first in a wave of new European launch companies to reach orbit, Ars reports. The Spectrum rocket consists of two stages, stands about 92 feet (28 meters) tall, and can haul payloads up to 1 metric ton (2,200 pounds) into low-Earth orbit. Based in Munich, Isar was founded by three university graduate students in 2018. Isar scrubbed a launch attempt Monday due to unfavorable winds at the launch site in Norway.

From the Arctic … Notably, this will be the first orbital launch attempt from a launch pad in Western Europe. The French-run Guiana Space Center in South America is the primary spaceport for European rockets. Virgin Orbit staged an airborne launch attempt from an airport in the United Kingdom in 2023, and the Plesetsk Cosmodrome is located in European Russia. The launch site for Isar is named Andøya Spaceport, located about 650 miles (1,050 kilometers) north of Oslo, inside the Arctic Circle. (submitted by EllPeaTea)

A chance for competition in Europe. The European Space Agency is inviting proposals to inject competition into the European launch market, an important step toward fostering a dynamic multiplayer industry officials hope one day will mimic that of the United States, Ars reports. The near-term plan for the European Launcher Challenge is for ESA to select companies for service contracts to transport ESA and other European government payloads to orbit from 2026 through 2030. A second component of the challenge is for companies to perform at least one demonstration of an upgraded launch vehicle by 2028. The competition is open to any European company working in the launch business.

Challenging the status quo … This is a major change from how ESA has historically procured launch services. Arianespace has been the only European launch provider available to ESA and other European institutions for more than 40 years. But there are private companies across Europe at various stages of developing their own small launchers, and potentially larger rockets, in the years ahead. With the European Launcher Challenge, ESA will provide each of the winners up to 169 million euros ($182 million), a significant cash infusion that officials hope will shepherd Europe’s nascent private launch industry toward liftoff. Companies like Isar Aerospace, Rocket Factory Augsburg, MaiaSpace, and PLD Space are among the contenders for ESA contracts.

Rocket Lab launches eight satellites. Rocket Lab launched eight satellites Wednesday for a German company that is expanding its constellation to detect and track wildfires, Space News reports. An Electron rocket lifted off from New Zealand and completed deploying its payload of eight CubeSats for OroraTech about 55 minutes later, placing them into Sun-synchronous orbits at an altitude of about 341 miles (550 kilometers). This was Rocket Lab’s fifth launch of the year, and the third in less than two weeks.

Fire goggles … OroraTech launched three satellites before this mission, fusing data from those satellites and government missions to detect and track wildfires. The new satellites are designed to fill a gap in coverage in the afternoon, a peak time for wildfire formation and spread. OroraTech plans to launch eight more satellites later this year. Wildfire monitoring from space is becoming a new application for satellite technology. Last month, OroraTech partnered with Spire for a contract to build a CubeSat constellation called WildFireSat for the Canadian Space Agency. Google is backing FireSat, another constellation of more than 50 satellites to be deployed in the coming years to detect and track wildfires. (submitted by EllPeaTea)

Should Britain have a sovereign launch capability? A UK House of Lords special inquiry committee has heard from industry experts on the importance of fostering a sovereign launch capability, European Spaceflight reports. On Monday, witnesses from the UK space industry testified that the nation shouldn’t rely on others, particularly the United States, to put satellites into orbit. “The idea that we will be able to do it through America… certainly in today’s, you know, the last 50 days, I think is very, very doubtful. The UK needs access to space,” said Scott Hammond, deputy CEO of SaxaVord Spaceport in Scotland.

Looking inward … A representative from one of the most promising UK launch startups agreed. “Most people who are looking to launch are beholden to the United States solutions or services that are there,” said Alan Thompson, head of government affairs at Skyrora. “Without having our own home-based or UK-based service provider, we risk not having that voice and not being able to undertake all these experiments or be able to manifest ourselves better in space.” The UK is the only nation to abandon an independent launch capability after putting a satellite into orbit. The British government canceled the Black Arrow rocket in the early 1970s, citing financial reasons. A handful of companies, including Skyrora, is working to restore the orbital launch business to the UK.

This rocket engine CEO faces some salacious allegations. The Independent published what it described as an exclusive report Monday describing a lawsuit filed against the CEO of RocketStar, a New York-based company that says its mission is “improving upon the engines that power us to the stars.” Christopher Craddock is accused of plundering investor funds to underwrite pricey jaunts to Europe, jewelry for his wife, child support payments, and, according to the company’s largest investor, “airline tickets for international call girls to join him for clandestine weekends in Miami,” The Independent reports. Craddock established RocketStar in 2014 after financial regulators barred him from working on Wall Street over a raft of alleged violations.

Go big or go home … The $6 million lawsuit filed by former CEO Michael Mojtahedi alleges RocketStar “is nothing more than a Ponzi scheme… [that] has been predicated on Craddock’s ability to con new people each time the company has run out of money.” On its website, RocketStar says its work focuses on aerospike rocket engines and a “FireStar Fusion Drive, the world’s first electric propulsion device enhanced with nuclear fusion.” These are tantalizing technologies that have proven elusive for other rocket companies. RocketStar’s attorney told The Independent: “The company denies the allegations and looks forward to vindicating itself in court.”

Another record for SpaceX. Last Thursday, SpaceX launched a batch of clandestine SpaceX-built surveillance satellites for the National Reconnaissance Office from Vandenberg Space Force Base in California, Spaceflight Now reports. This was the latest in a series of flights populating the NRO’s constellation of low-Earth orbit reconnaissance satellites. What was unique about this mission was its use of a Falcon 9 first stage booster that flew to space just nine days prior with a NASA astronomy satellite. The successful launch broke the record for the shortest span between flights of the same Falcon 9 booster, besting a 13.5-day turnaround in November 2024.

A mind-boggling number of launches … This flight also marked the 450th launch of a Falcon 9 rocket since its debut in 2010, and the 139th within a 365-day period, despite suffering its first mission failure in nearly 10 years and a handful of other glitches. SpaceX’s launch pace is unprecedented in the history of the space industry. No one else is even close. In the last Rocket Report I authored, I wrote that SpaceX’s steamroller no longer seems to be rolling downhill. That may be the case as the growth in the Falcon 9 launch cadence has slowed, but it’s hard for me to see anyone else matching SpaceX’s launch rate until at least the 2030s.

Rocket Lab and Stoke Space find an on-ramp. Space Systems Command announced Thursday that it selected Rocket Lab and Stoke Space to join the Space Force’s National Security Space Launch (NSSL) program. The contracts have a maximum value of $5.6 billion, and the Space Force will dole out “task orders” for individual missions as they near launch. Rocket Lab and Stoke Space join SpaceX, ULA, and Blue Origin as eligible launch providers for lower-priority national security satellites, a segment of missions known as Phase 3 Lane 1 in the parlance of the Space Force. For these missions, the Space Force won’t require certification of the rockets, as the military does for higher-value missions in the so-called “Lane 2” segment. However, Rocket Lab and Stoke Space must complete at least one successful flight of their new Neutron and Nova rockets before they are cleared to launch national security payloads.

Stoked at Stoke … This is a big win for Rocket Lab and Stoke. For Rocket Lab, it bolsters the business case for the medium-class Neutron rocket it is developing for flights from Wallops Island, Virginia. Neutron will be partially reusable with a recoverable first stage. But Rocket Lab already has a proven track record with its smaller Electron launch vehicle. Stoke hasn’t launched anything, and it has lofty ambitions for a fully reusable two-stage rocket called Nova. This is a huge vote of confidence in Stoke. When the Space Force released its invitation for an on-ramp to the NSSL program last year, it said bidders must show a “credible plan for a first launch by December 2025.” Smart money is that neither company will launch its rockets by the end of this year, but I’d love to be proven wrong.

Falcon 9 deploys spy satellite. Monday afternoon, a SpaceX Falcon 9 took flight from Florida’s Space Coast and delivered a national security payload designed, built, and operated by the National Reconnaissance Office into orbit, Florida Today reports. Like almost all NRO missions, details about the payload are classified. The mission codename was NROL-69, and the launch came three-and-a-half days after SpaceX launched another NRO mission from California. While we have some idea of what SpaceX launched from California last week, the payload for the NROL-69 mission is a mystery.

Space sleuthing … There’s an online community of dedicated skywatchers who regularly track satellites as they sail overhead around dawn and dusk. The US government doesn’t publish the exact orbital parameters for its classified spy satellites (they used to), but civilian trackers coordinate with one another, and through a series of observations, they can produce a pretty good estimate of a spacecraft’s orbit. Marco Langbroek, a Dutch archeologist and university lecturer on space situational awareness, is one of the best at this, using publicly available information about the flight path of a launch to estimate when the satellite will fly overhead. He and three other observers in Europe managed to locate the NROL-69 payload just two days after the launch, plotting the object in an orbit between 700 and 1,500 kilometers at an inclination of 64.1 degrees to the equator. Analysts speculated this mission might carry a pair of naval surveillance spacecraft, but this orbit doesn’t match up well with any known constellations of NRO satellites.

NASA continues with Artemis II preps. Late Saturday night, technicians at Kennedy Space Center in Florida moved the core stage for NASA’s second Space Launch System rocket into position between the vehicle’s two solid-fueled boosters, Ars reports. Working inside the iconic 52-story-tall Vehicle Assembly Building, ground teams used heavy-duty cranes to first lift the butterscotch orange core stage from its cradle, then rotate it to a vertical orientation and lift it into a high bay, where it was lowered into position on a mobile launch platform. The 212-foot-tall (65-meter) core stage is the largest single hardware element for the Artemis II mission, which will send a team of four astronauts around the far side of the Moon and back to Earth as soon as next year.

Looking like a go … With this milestone, the slow march toward launch continues. A few months ago, some well-informed people in the space community thought there was a real possibility the Trump administration could quickly cancel NASA’s Space Launch System, the high-priced heavy-lifter designed to send astronauts from the Earth to the Moon. The most immediate possibility involved terminating the SLS program before it flies with Artemis II. This possibility appears to have been overcome by circumstances. The rockets most often mentioned as stand-ins for the Space Launch System—SpaceX’s Starship and Blue Origin’s New Glenn—aren’t likely to be cleared for crew missions for at least several years. The long-term future of the Space Launch System remains in doubt.

Space Force says Vulcan is good to go. The US Space Force on Wednesday announced that it has certified United Launch Alliance’s Vulcan rocket to conduct national security missions, Ars reports. “Assured access to space is a core function of the Space Force and a critical element of national security,” said Brig. Gen. Kristin Panzenhagen, program executive officer for Assured Access to Space, in a news release. “Vulcan certification adds launch capacity, resiliency, and flexibility needed by our nation’s most critical space-based systems.” The formal announcement closes a yearslong process that has seen multiple delays in the development of the Vulcan rocket, as well as two anomalies in recent years that were a further setback to certification.

Multiple options … This certification allows ULA’s Vulcan to launch the military’s most sensitive national security missions, a separate lot from those Rocket Lab and Stoke Space are now eligible for (as we report in a separate Rocket Report entry). It elevates Vulcan to launch these missions alongside SpaceX’s Falcon 9 and Falcon Heavy rockets. Vulcan will not be the next rocket that the company launches, however. First up is one of the company’s remaining Atlas V boosters, carrying Project Kuiper broadband satellites for Amazon. This launch could occur in April, although ULA has not set a date. This will be followed by the first Vulcan national security launch, which the Space Force says could occur during the coming “summer.”

With Vulcan’s certification, Space Force is no longer solely reliant on SpaceX

Space, united launch alliance, US Space Force, vulcan rocket / Shannon Garcia / March 27, 2025

The US Space Force on Wednesday announced that it has certified United Launch Alliance’s Vulcan rocket to conduct national security missions.

“Assured access to space is a core function of the Space Force and a critical element of national security,” said Brig. Gen. Panzenhagen, program executive officer for Assured Access to Space, in a news release. “Vulcan certification adds launch capacity, resiliency, and flexibility needed by our nation’s most critical space-based systems.”

The formal announcement closes a yearslong process that has seen multiple delays in the development of the Vulcan rocket, as well as two anomalies in recent years that were a further setback to certification.

The first of these, an explosion on a test stand in northern Alabama during the spring of 2023, delayed the first test flight of Vulcan by several months. Then, in October 2024, during the second test flight of the rocket, a nozzle on one of the Vulcan’s two side-mounted boosters failed.

A cumbersome process

This nozzle issue, more than five months ago, compounded the extensive paperwork needed to certify Vulcan for the US Department of Defense’s most sensitive missions. The military has several options for companies to certify their rockets depending on the number of flights completed, which could be two, three, or more. The fewer the flights, the more paperwork and review that must be done. For Vulcan, this process entailed:

52 certification criteria
more than 180 discrete tasks
2 certification flight demonstrations
60 payload interface requirement verifications
18 subsystem design and test reviews
114 hardware and software audits

That sounds like a lot of work, but at least the military’s rules and regulations are straightforward and simple to navigate, right? Anyway, the certification process is complete, elevating United Launch Alliance to fly national security missions alongside SpaceX with its fleet of Falcon 9 and Falcon Heavy rockets.

Welcome to Edition 7.35 of the Rocket Report! SpaceX’s steamroller is still rolling, but for the first time in many years, it doesn’t seem like it’s rolling downhill. After a three-year run of perfect performance—with no launch failures or any other serious malfunctions—SpaceX’s Falcon 9 rocket has suffered a handful of issues in recent months. Meanwhile, SpaceX’s next-generation Starship rocket is having problems, too. Kiko Dontchev, SpaceX’s vice president of launch, addressed some (but not all) of these concerns in a post on X this week. Despite the issues with the Falcon 9, SpaceX has maintained a remarkable launch cadence. As of Thursday, SpaceX has launched 28 Falcon 9 flights since January 1, ahead of last year’s pace.

Alpha rocket preps for weekend launch. While Firefly Aerospace is making headlines for landing on the Moon, its Alpha rocket is set to launch again as soon as Saturday morning from Vandenberg Space Force Base, California. The two-stage, kerosene-fueled rocket will launch a self-funded technology demonstration satellite for Lockheed Martin. It’s the first of up to 25 launches Lockheed Martin has booked with Firefly over the next five years. This launch will be the sixth flight of an Alpha rocket, which has become a leader in the US commercial launch industry for dedicated missions with 1 ton-class satellites.

Firefly’s OG … The Alpha rocket was Firefly’s first product, and it has been a central piece of the company’s development since 2014. Like Firefly itself, the Alpha rocket program has gone through multiple iterations, including a wholesale redesign nearly a decade ago. Sure, Firefly can’t claim any revolutionary firsts with the Alpha rocket, as it can with its Blue Ghost lunar lander. But without Alpha, Firefly wouldn’t be where it is today. The Texas-based firm is one of only four US companies with an operational orbital-class rocket. One thing to watch for is how quickly Firefly can ramp up its Alpha launch cadence. The rocket only flew once last year.

Isar Aerospace celebrates another win. In last week’s Rocket Report, we mentioned that the German launch startup Isar Aerospace won a contract with a Japanese company to launch a 200-kilogram commercial satellite in 2026. But wait, there’s more! On Wednesday, the Norwegian Space Agency announced it awarded a contract to Isar Aerospace for the launch of a pair of satellites for the country’s Arctic Ocean Surveillance initiative, European Spaceflight reports. The satellites are scheduled to launch on Isar’s Spectrum rocket from Andøya Spaceport in Norway by 2028.

First launch pending … These recent contract wins are a promising sign for Isar Aerospace, which is also vying for contracts to launch small payloads for the European Space Agency. The Spectrum rocket could launch on its inaugural flight within a matter of weeks, and if successful, it could mark a transformative moment for the European space industry, which has long been limited to a single launch provider: the French company Arianespace.

Mother Nature holds up Oz launch. The first launch by Gilmour Space has been postponed again due to a tropical cyclone that brought severe weather to Australia’s Gold Coast region earlier this month, InnovationAus.com reports. Tropical Cyclone Alfred didn’t significantly impact Gilmour’s launch site, but the storm did cause the company to suspend work at its corporate headquarters in Southeast Queensland. With the storm now over, Gilmour is reassessing when it might be ready to launch its Eris rocket. Reportedly, the delay could be as long as two weeks or more.

A regulatory storm … Gilmour aims to become the first Australian company to launch a rocket into orbit. Last month, Gilmour announced the launch date for the Eris rocket was set for no earlier than March 15, but Tropical Cyclone Alfred threw this schedule out the window. Gilmour said it received a launch license from the Australian Space Agency in November and last month secured approvals to clear airspace around the launch site. But there’s still a hitch. The license is conditional on final documentation for the launch being filed and agreed with the space agency, and this process is stretching longer than anticipated. (submitted by ZygP)

What is going on at SpaceX? As we mention in the introduction to this week’s Rocket Report, it has been an uncharacteristically messy eight months for SpaceX. These speed bumps include issues with the Falcon 9 rocket’s upper stage on three missions, two lost Falcon 9 boosters, and consecutive failures of SpaceX’s massive Starship rocket on its first two test flights of the year. So what’s behind SpaceX’s bumpy ride? Ars wrote about the pressures facing SpaceX employees as Elon Musk pushes his workforce ever-harder to accelerate toward what Musk might call a multi-planetary future.

Headwinds or tailwinds? … No country or private company ever launched as many times as SpaceX flew its fleet of Falcon 9 rockets in 2024. At the same time, the company has been attempting to move its talented engineering team off the Falcon 9 and Dragon programs and onto Starship to keep that ambitious program moving forward. This is all happening as Musk has taken on significant roles in the Trump administration, stirring controversy and raising questions about his motives and potential conflicts of interest. However, it may be not so much Musk’s absence from SpaceX that is causing these issues but more the company’s relentless culture. As my colleague Eric Berger suggested in his piece, it seems possible that, at least for now, SpaceX has reached the speed limit for commercial spaceflight.

A titan of Silicon Valley enters the rocket business. Former Google chief executive Eric Schmidt has taken a controlling interest in the Long Beach, California-based Relativity Space, Ars reports. Schmidt’s involvement with Relativity has been quietly discussed among space industry insiders for a few months. Multiple sources told Ars that he has largely been bankrolling the company since the end of October, when the company’s previous fundraising dried up. Now, Schmidt is Relativity’s CEO.

Unclear motives … It is not immediately clear why Schmidt is taking a hands-on approach at Relativity. However, it is one of the few US-based companies with a credible path toward developing a medium-lift rocket that could potentially challenge the dominance of SpaceX and its Falcon 9 rocket. If the Terran R booster becomes commercially successful, it could play a big role in launching megaconstellations. Schmidt’s ascension also means that Tim Ellis, the company’s co-founder, chief executive, and almost sole public persona for nearly a decade, is now out of a leadership position.

Falcon 9 deploys NASA’s newest space telescope. Satellites come in all shapes and sizes, but there aren’t any that look quite like SPHEREx, an infrared observatory NASA launched Tuesday night in search of answers to simmering questions about how the Universe, and ultimately life, came to be, Ars reports. The SPHEREx satellite rocketed into orbit from California aboard a SpaceX Falcon 9 rocket, beginning a two-year mission surveying the sky in search of clues about the earliest periods of cosmic history, when the Universe rapidly expanded and the first galaxies formed. SPHEREx will also scan for pockets of water ice within our own galaxy, where clouds of gas and dust coalesce to form stars and planets.

Excess capacity … SPHEREx has lofty goals, but it’s modest in size, weighing just a little more than a half-ton at launch. This meant the Falcon 9 rocket had plenty of extra room for four other small satellites that will fly in formation to image the solar wind as it travels from the Sun into the Solar System. The four satellites are part of NASA’s PUNCH mission. SPHEREx and PUNCH are part of NASA’s Explorers program, a series of cost-capped science missions with a lineage going back to the dawn of the Space Age. SPHEREx and PUNCH have a combined cost of about $638 million. (submitted by EllPeaTea)

China has launched another batch of Internet satellites. A new group of 18 satellites entered orbit Tuesday for the Thousand Sails constellation with the first launch from a new commercial launch pad, Space News reports. The satellites launched on top of a Long March 8 rocket from Hainan Commercial Launch Site near Wenchang on Hainan Island. The commercial launch site has two pads, the first of which entered service with a launch last year. This mission was the first to launch from the other pad at the commercial spaceport, which is gearing up for an uptick in Chinese launch activity to continue deploying satellites for the Thousand Sails network and other megaconstellations.

Sailing on … The Thousand Sails constellation, also known as Qianfan, or G60 Starlink, is a broadband satellite constellation spearheaded by Shanghai Spacecom Satellite Technology (SSST), also known as Spacesail, Space News reported. The project, which aims to deploy 14,000 satellites, seeks to compete in the global satellite Internet market. Spacesail has now launched 90 satellites into near-polar orbits, and the operator previously stated it aims to have 648 satellites in orbit by the end of 2025. If Spacesail continues launching 18 satellites per rocket, this goal would require 31 more launches this year. (submitted by EllPeaTea)

NASA, SpaceX call off astronaut launch. With the countdown within 45 minutes of launch, NASA called off an attempt to send the next crew to the International Space Station Wednesday evening to allow more time to troubleshoot a ground system hydraulics issue, CBS News reports. During the countdown Wednesday, SpaceX engineers were troubleshooting a problem with one of two clamp arms that hold the Falcon 9 rocket to its strongback support gantry. Hydraulics are used to retract the two clamps prior to launch.

Back on track … NASA confirmed Thursday SpaceX ground teams completed inspections of the hydraulics system used for the clamp arm supporting the Falcon 9 rocket and successfully flushed a suspected pocket of trapped air in the system, clearing the way for another launch attempt Friday evening. This mission, known as Crew-10, will ferry two NASA astronauts, a Japanese mission specialist, and a Russian cosmonaut to the space station. They will replace a four-person crew currently at the ISS, including Butch Wilmore and Suni Williams, who have been in orbit since last June after flying to space on Boeing’s Starliner capsule. Starliner returned to Earth without its crew due to a problem with overheating thrusters, leaving Wilmore and Williams behind to wait for a ride home with SpaceX.

SpaceX’s woes reach Poland’s space agency. The president of the Polish Space Agency, Grzegorz Wrochna, has been dismissed following a botched response to the uncontrolled reentry of a Falcon 9 second stage that scattered debris across multiple locations in Poland, European Spaceflight reports. The Falcon 9’s upper stage was supposed to steer itself toward a controlled reentry last month after deploying a set of Starlink satellites, but a propellant leak prevented it from doing so. Instead, the stage remained in orbit for nearly three weeks before falling back into the atmosphere February 19, scattering debris fragments at several locations in Poland.

A failure to communicate … In the aftermath of the Falcon 9’s uncontrolled reentry, the Polish Space Agency (POLSA) claimed it sent warnings of the threat of falling space debris to multiple departments of the Polish government. One Polish ministry disputed this claim, saying it was not adequately warned about the uncontrolled reentry. POLSA later confirmed it sent information regarding the reentry to a wrong email address. Making matters worse, the Polish Space Agency reported it was hacked on March 2. The Polish government apparently had enough and fired the head of the space agency March 11.

Vulcan booster anomaly blamed on “manufacturing defect.” The loss of a solid rocket motor nozzle on the second flight of United Launch Alliance’s Vulcan Centaur last October was caused by a manufacturing defect, Space News reports. In a roundtable with reporters Wednesday, ULA chief executive Tory Bruno said the problem has been corrected as the company awaits certification of the Vulcan rocket by the Space Force. The nozzle fell off the bottom of one of the Vulcan launcher’s twin solid rocket boosters about a half-minute into its second test flight last year. The rocket continued its climb into space, but ULA and Northrop Grumman, which supplies solid rocket motors for Vulcan, set up an investigation to find the cause of the nozzle malfunction.

All the trimmings … Bruno said the anomaly was traced to a “manufacturing defect” in one of the internal parts of the nozzle, an insulator. Specific details, he said, remained proprietary, according to Space News. “We have isolated the root cause and made appropriate corrective actions,” he said, which were confirmed in a static-fire test of a motor at a Northrop test site in Utah in February. “So we are back continuing to fabricate hardware and, at least initially, screening for what that root cause was.” Bruno said the investigation was aided by recovery of hardware that fell off the motor while in flight and landed near the launch pad in Florida, as well as “trimmings” of material left over from the manufacturing process. ULA also recovered both boosters from the ocean so engineers could compare the one that lost its nozzle to the one that performed normally. The defective hardware “just stood out night and day,” Bruno said. “It was pretty clear that that was an outlier, far out of family.” Meanwhile, ULA has trimmed its launch forecast for this year, from a projection of up to 20 launches down to a dozen.

ULA’s Vulcan rocket still doesn’t have the Space Force’s seal of approval

Amazon, kuiper, launch, military space, Science, Space, space force, united launch alliance, vulcan / Mike M. / February 12, 2025

ULA crews at Cape Canaveral have already stacked the next Vulcan rocket on its mobile launch platform in anticipation of launching the USSF-106 mission. But with the Space Force’s Space Systems Command still withholding certification, there’s no confirmed launch date for USSF-106.

So ULA is pivoting to another customer on its launch manifest.

Amazon’s first group of production satellites for the company’s Kuiper Internet network is now first in line on ULA’s schedule. Amazon confirmed last month that it would ship Kuiper satellites to Cape Canaveral from its factory in Kirkland, Washington. Like ULA, Amazon has run into its own delays with manufacturing Kuiper satellites.

“These satellites, built to withstand the harsh conditions of space and the journey there, will be processed upon arrival to get them ready for launch,” Amazon posted on X. “These satellites will bring fast, reliable Internet to customers even in remote areas. Stay tuned for our first launch this year.”

Amazon and the Space Force take up nearly all of ULA’s launch backlog. Amazon has eight flights reserved on Atlas V rockets and 38 missions booked on the Vulcan launcher to deploy about half of its 3,232 satellites to compete with SpaceX’s Starlink network. Amazon also has launch contracts with Blue Origin, which is owned by Amazon founder Jeff Bezos, along with Arianespace and SpaceX.

The good news is that United Launch Alliance has an inventory of rockets awaiting an opportunity to fly. The company plans to finish manufacturing its remaining 15 Atlas V rockets within a few months, allowing the factory in Decatur, Alabama, to focus solely on producing Vulcan launch vehicles. ULA has all the major parts for two Vulcan rockets in storage at Cape Canaveral.

“We have a stockpile of rockets, which is kind of unusual,” Bruno said. “Normally, you build it, you fly it, you build another one… I would certainly want anyone who’s ready to go to space able to go to space.”

Space Force officials now aim to finish the certification of the Vulcan rocket in late February or early March. This would clear the path for launching the USSF-106 mission after the next Atlas V. Once the Kuiper launch gets off the ground, teams will bring the Vulcan rocket’s components back to the hangar to be stacked again.

The Space Force has not set a launch date for USSF-106, but the service says liftoff is targeted for sometime between the beginning of April and the end of June, nearly five years after ULA won its lucrative contract.

Welcome to Edition 7.17 of the Rocket Report! Next week marks 10 years since one of the more spectacular launch failures of this century. On October 28, 2014, an Antares rocket, then operated by Orbital Sciences, suffered an engine failure six seconds after liftoff from Virginia and crashed back onto the pad in a fiery twilight explosion. I was there and won’t forget seeing the rocket falter just above the pad, being shaken by the deafening blast, and then running for cover. The Antares rocket is often an afterthought in the space industry, but it has an interesting backstory touching on international geopolitics, space history, and novel engineering. Now, Northrop Grumman and Firefly Aerospace are developing a new version of Antares.

Astra gets a lifeline from DOD. Astra, the launch startup that was taken private again earlier this year for a sliver of its former value, has landed a new contract with the Defense Innovation Unit (DIU) to support the development of a next-gen launch system for time-sensitive space missions, TechCrunch reports. The contract, which the DIU awarded under its Novel Responsive Space Delivery (NRSD) program, has a maximum value of $44 million. The money will go toward the continued development of Astra’s Launch System 2, designed to perform rapid, ultra-low-cost launches.

Guarantees? … It wasn’t clear from the initial reporting how much money DIU is actually committing to Astra, which said the contract will fund continued development of Launch System 2. Launch System 2 includes a small-class launch vehicle with a similarly basic name, Rocket 4, and mobile ground infrastructure designed to be rapidly set up at austere spaceports. Adam London, founder and chief technology officer at Astra, said the contract award is a “major vote of confidence” in the company. If Astra can capitalize on the opportunity, this would be quite a remarkable turnaround. After going public at an initial valuation of $2.1 billion, or $12.90 per share, Astra endured multiple launch failures with its previous rocket and risked bankruptcy before the company’s co-founders, Chris Kemp and Adam London, took the company private again this year at a price of just $0.50 per share.

Blue Origin debuts a new New Shepard. Jeff Bezos’ Blue Origin space venture successfully sent a brand-new New Shepard rocket ship on an uncrewed shakedown cruise Wednesday, with the aim of increasing the company’s capacity to take people on suborbital space trips, GeekWire reports. The capsule, dubbed RSS Karman Line, carried payloads instead of people when it lifted off from Blue Origin’s Launch Site One in West Texas. But if all the data collected during the 10-minute certification flight checks out, it won’t be long before crews climb aboard for similar flights.

Now there are two … With this week’s flight, Blue Origin now has two human-rated suborbital capsules in its fleet, along with two boosters. This should allow the company to ramp up the pace of its human missions, which have historically flown at a cadence of about one flight every two to three months. The new capsule, named for the internationally recognized boundary of space 62 miles (100 kilometers) above Earth, features upgrades to improve performance and ease reusability.

China has a new space tourism company. Chinese launch startup Deep Blue Aerospace targets providing suborbital tourism flights starting in 2027, Space News reports. The company was already developing a partially reusable orbital rocket named Nebula-1 for satellite launches and recently lost a reusable booster test vehicle during a low-altitude test flight. While Deep Blue moves forward with more Nebula-1 testing before its first orbital launch, the firm is now selling tickets for rides to suborbital space on a six-person capsule. The first two tickets were expected to be sold Thursday in a promotional livestream event.

Architectural considerations … Deep Blue has a shot at becoming China’s first space tourism company and one of only a handful in the world, joining US-based Blue Origin and Virgin Galactic in the market for suborbital flights. Deep Blue’s design will be a single-stage reusable rocket and crew capsule, similar to Blue Origin’s New Shepard, capable of flying above the Kármán line and providing up to 10 minutes of microgravity experience for its passengers before returning to the ground. A ticket, presumably for a round trip, will cost about $210,000. (submitted by Ken the Bin)

France’s space agency aims to launch a FROG. French space agency CNES will begin flight testing a small reusable rocket demonstrator called FROG-H in 2025, European Spaceflight reports. FROG is a French acronym that translates to Rocket for GNC demonstration, and its purpose is to test landing algorithms for reusable launch vehicles. CNES manages the program in partnership with French nonprofits and universities. At 11.8 feet (3.6 meters) tall, FROG is the smallest launch vehicle prototype at CNES, which says it will test concepts and technologies at small scale before incorporating them into Europe’s larger vertical takeoff/vertical landing test rockets like Callisto and Themis. Eventually, the idea is for all this work to lead to a reusable European orbital-class rocket.

Building on experience … CNES flew a jet-powered demonstrator named FROG-T on five test flights beginning in May 2019, reaching a maximum altitude of about 100 feet (30 meters). FROG-H will be powered by a hydrogen peroxide rocket engine developed by the Łukasiewicz Institute of Aviation in Poland under a European Space Agency contract. The first flights of FROG-H are scheduled for early 2025. The structure of the FROG project seeks to “break free from traditional development methods” by turning to “teams of enthusiasts” to rapidly develop and test solutions through an experimental approach, CNES says on its website.

Falcon 9 sweeps NSSL awards. The US Space Force’s Space Systems Command announced on October 18 it has ordered nine launches from SpaceX in the first batch of dozens of missions the military will buy in a new phase of competition for lucrative national security launch contracts, Ars reports. The parameters of the competition limited the bidders to SpaceX and United Launch Alliance (ULA). SpaceX won both task orders for a combined value of $733.5 million, or roughly $81.5 million per mission. Six of the nine missions will launch from Vandenberg Space Force Base, California, beginning as soon as late 2025. The other three will launch from Cape Canaveral Space Force Station, Florida.

Head-to-head … This was the first set of contract awards by the Space Force’s National Security Space Launch (NSSL) Phase 3 procurement round and represents one of the first head-to-head competitions between SpaceX’s Falcon 9 and ULA’s Vulcan rocket. The nine launches were divided into two separate orders, and SpaceX won both. The missions will deploy payloads for the National Reconnaissance Office and the Space Development Agency.

SpaceX continues deploying NRO megaconstellation. SpaceX launched more surveillance satellites for the National Reconnaissance Office Thursday aboard a Falcon 9 rocket, Spaceflight Now reports. While the secretive spy satellite agency did not identify the number or exact purpose of the satellites, the Falcon 9 likely deployed around 20 spacecraft believed to be based on SpaceX’s Starshield satellite bus, a derivative of the Starlink spacecraft platform, with participation from Northrop Grumman. These satellites host classified sensors for the NRO. This is the fourth SpaceX launch for the NRO’s new satellite fleet, which seeks to augment the agency’s bespoke multibillion-dollar spy satellites with a network of smaller, cheaper, more agile platforms in low-Earth orbit.

The century mark … This mission, officially designated NROL-167, was the 100th flight of a Falcon 9 rocket this year and the 105th SpaceX launch overall in 2024. The NRO has not said how many satellites will make up its fleet when completed, but the intelligence agency says it will be the US government’s largest satellite constellation in history. By the end of the year, the NRO expects to have 100 or more of these satellites in orbit, allowing the agency to transition from a demonstration mode to an operational mode to deliver intelligence data to military and government users. Many more launches are expected through 2028. (submitted by Ken the Bin)

ULA is stacking its third Vulcan rocket. United Launch Alliance has started assembling its next Vulcan rocket—the first destined to launch a US military payload—as the Space Force prepares to certify it to loft the Pentagon’s most precious national security satellites, Ars reports. Space Force officials expect to approve ULA’s Vulcan rocket for military missions without requiring another test flight, despite an unusual problem on the rocket’s second demonstration flight earlier this month, when one of Vulcan’s two strap-on solid-fueled boosters lost its nozzle shortly after liftoff.

Pending certification … Despite the nozzle failure, the Vulcan rocket continued climbing into space and eventually reached its planned injection orbit, and the Space Force and ULA declared the test flight a success. Still, engineers want to understand what caused the nozzle to break apart and decide on corrective actions before the Space Force clears the Vulcan rocket to launch a critical national security payload. This could take a little longer than expected due to the booster problem, but Space Force officials still hope to certify the Vulcan rocket in time to support a national security launch by the end of the year.

Blue Origin’s first New Glenn has all its engines. Blue Origin published a photo Thursday on X showing all seven first-stage BE-4 engines installed on the base of the company’s first New Glenn rocket. This is a notable milestone as Blue Origin proceeds toward the first launch of the heavy-lifter, possibly before the end of the year. But there’s a lot of work for Blue Origin to accomplish before then. These steps include rolling the rocket to the launch pad, running through propellant loading tests and practice countdowns, and then test-firing all seven BE-4 engines on the pad at Cape Canaveral Space Force Station, Florida.

Seven for seven … The BE-4 engines will consume methane fuel mixed with liquid oxygen for the first few minutes of the New Glenn flight, generating more than 3.8 million pounds of combined thrust. The seven BE-4s on New Glenn are similar to the BE-4 engines that fly two at a time on ULA’s Vulcan rocket. Dave Limp, Blue Origin’s CEO, said three of the seven engines on the New Glenn first stage have thrust vector control capability to provide steering during launch, reentry, and landing on the company’s offshore recovery vessel. “That gimbal capability, along with the landing gear and Reaction Control System thrusters, are key to making our booster fully reusable,” Limp wrote on X. “Fun fact: The vehicle’s max design gimbal condition is during ascent when it has to fight high-altitude winds.”

Next Super Heavy booster test-fired in Texas. SpaceX fired up the Raptor engines on its next Super Heavy booster, numbered Booster 13, Thursday evening at the company’s launch site in South Texas. This happened just 11 days after SpaceX launched and caught the Super Heavy booster on the previous Starship test flight and signals SpaceX could be ready for the next Starship test flight sometime in November. SpaceX has already test-fired the Starship upper stage for the next flight.

Great expectations … We expect the next Starship flight, which will be program’s sixth full-scale demo mission, will include another booster catch back at the launch tower at Starbase, Texas. SpaceX may also attempt to reignite a Raptor engine on the Starship upper stage while it is in space, demonstrating the capability to steer itself back into the atmosphere on future flights. So far, SpaceX has only launched Starships on long, arcing suborbital trajectories that carry the vehicle halfway around the world before reentry. In order to actually launch a Starship into a stable orbit around Earth, SpaceX will want to show it can bring the vehicle back so it doesn’t reenter the atmosphere in an uncontrolled manner. An uncontrolled reentry of a large spacecraft like Starship could pose a public safety risk.

ULA’s second Vulcan rocket lost part of its booster and kept going

launch, military space, Science, Space, united launch alliance, vulcan / Kelly Newman / October 4, 2024

The US Space Force says this test flight was critical for certifying Vulcan for military missions.

United Launch Alliance’s Vulcan rocket, under contract for dozens of flights for the US military and Amazon’s Kuiper broadband network, lifted off from Florida on its second test flight Friday, suffered an anomaly with one of its strap-on boosters, and still achieved a successful mission, the company said in a statement.

This test flight, known as Cert-2, is the second certification mission for the new Vulcan rocket, a milestone that paves the way for the Space Force to clear ULA’s new rocket to begin launching national security satellites in the coming months.

While ULA said the Vulcan rocket continued to hit its marks during the climb into orbit Friday, engineers are investigating what happened with one of its solid rocket boosters shortly after liftoff.

After a last-minute aborted countdown earlier in the morning, the 202-foot-tall (61.6-meter) Vulcan rocket lit its twin methane-fueled BE-4 engines and two side-mounted solid rocket boosters to climb away from Cape Canaveral Space Force Station, Florida, at 7: 25 am EDT (11: 25 UTC) Friday.

A little tilt

As the rocket arced east from Cape Canaveral, a shower of sparks suddenly appeared at the base of the Vulcan rocket around 37 seconds into the mission. The exhaust plume from one of the strap-on boosters, made by Northrop Grumman, changed significantly, and the rocket slightly tilted on its axis before the guidance system and main engines made a steering correction.

Videos from the launch show the booster’s nozzle, the bell-shaped exhaust exit cone at the bottom of the booster, fall away from the rocket.

“It looks dramatic, like all things on a rocket,” Bruno wrote on X. “But it’s just the release of the nozzle. No explosions occurred.”

During the ascent of the Vulcan rocket on the #Cert2 mission, there appeared to be an issue with the solid rocket booster on the right side of the vehicle as seen from the KSC Press Site. However, the Centaur was able to reach orbit.https://t.co/3iwWLVWZHp

— Spaceflight Now (@SpaceflightNow) October 4, 2024

The Federal Aviation Administration, which licenses commercial space launches in the United States, said in a statement that it assessed the booster anomaly and “determined no investigation is warranted at this time.” The FAA is not responsible for regulating launch vehicle anomalies unless they impact public safety.

The Vulcan rocket comes in several configurations, with zero, two, four, or six solid-fueled boosters clustered around the liquid-fueled core stage. ULA can tailor the configuration based on the parameters of each mission, such as payload mass and target orbit.

The boosters, which Northrop Grumman calls graphite epoxy motors, are 63 inches (1.6 meters) in diameter and 72 feet (22 meters) long. Their nozzles are made of a composite heat-resistant carbon-phenolic material.

Bruno added that the rest of the damaged booster’s composite casing held up fine during its roughly 90-second burn, but the anomaly caused “reduced, asymmetric thrust” that the rocket compensated for during the rest of its ascent into space.

The Federal Aviation Administration, which regulates commercial space launches, is not immediately requiring an investigation into the booster anomaly. The FAA said it is “assessing the operation and will issue an updated statement if the agency determines an investigation is warranted.”

Remarkably, the Vulcan rocket soldiered on and jettisoned both strap-on boosters to fall into the Atlantic Ocean. They’re not designed for recovery, so ULA and Northrop Grumman engineers will have to piece together what happened from imagery and performance data beamed down from the rocket in flight.

The BE-4 main engines, supplied by Jeff Bezos’ space company Blue Origin, appeared to work flawlessly for the first five minutes of the flight. The core stage shut down its engines and separated from Vulcan’s Centaur upper stage, which ignited two Aerojet Rocketdyne RL10 engines to propel the rocket into orbit.

Live data displayed on ULA’s webcast of the launch suggested the RL10 engines fired for approximately 20 seconds longer than planned, apparently to compensate for the lower thrust from the damaged booster during the first phase of the flight. The Centaur upper stage completed a second burn about a half-hour into the mission.

The rocket did not carry a real satellite. Earlier this year, ULA decided to launch a dummy payload to simulate the mass of a spacecraft, when it became clear the original payload for Vulcan’s second flight—Sierra Space’s first Dream Chaser spaceplane—would not be ready to fly this fall. ULA says it self-funded most of the cost of the Cert-2 test flight, which Bruno suggested was somewhere below $100 million.

Bullseye insertion

“Orbital insertion was perfect,” Bruno wrote on X.

The Centaur engines were supposed to fire a third time later Friday to send the rocket on a trajectory to escape Earth orbit and head into the Solar System. ULA also planned to perform experiments with the Centaur upper stage to demonstrate technologies and capabilities for longer-duration missions that could eventually last days, weeks, or months. The company did not provide an update on the results of these experiments.

Friday morning’s launch follows the debut test flight of the Vulcan rocket on January 8, which sent a commercial lunar lander from Astrobotic on a trajectory toward the Moon. The launch in January was nearly perfect.

ULA is a 50-50 joint venture between Boeing and Lockheed Martin, which merged their rocket divisions to form a single company in 2006. SpaceX, with its Falcon 9 and Falcon Heavy rockets, is ULA’s main competitor in the market for launching large US military satellites into orbit.

In 2020, the Pentagon awarded ULA and SpaceX multibillion-dollar “Phase 2” contracts to share responsibilities for launching dozens of national security space missions through 2027. Defense officials selected ULA’s Vulcan rocket to launch 25 national security missions, the majority of the launches up for competition. The rest went to SpaceX’s Falcon 9 and Falcon Heavy, which started delivering on its Phase 2 contract in January 2023.

Later this year, the Space Force is expected to select up to three companies—almost certainly ULA, SpaceX, and perhaps Blue Origin with its soon-to-debut New Glenn rocket—in a fresh competition to be eligible for contracts to launch the military’s largest spacecraft through 2029.

The Space Force required ULA to complete two successful Vulcan test flights before clearing the new rocket for launching military satellites. Despite the booster malfunction, ULA officials clearly believe the Vulcan rocket did enough Friday for the Space Force to certify it.

“The success of Vulcan’s second certification flight heralds a new age of forward-looking technology committed to meeting the ever-growing requirements of space launch and supporting our nation’s assured access to space,” Bruno said in a statement. “We had an observation on one of our solid rocket boosters (SRBs) that we are reviewing, but we are overall pleased with the rocket’s performance and had a bullseye insertion.”

In a press release after Friday’s launch, the Space Force hailed the test flight as a “certification milestone.”

“This is a significant achievement for both ULA and an important milestone for the nation’s strategic space lift capability,” said Brig. Gen. Kristin Panzenhagen, Space Systems Command’s program executive officer for assured access to space. “The Space Force’s partnership with launch companies, such as ULA, are absolutely critical in deploying on-orbit capabilities that protect our national interests.

“We are already starting to review the performance data from this launch, and we look forward to Vulcan meeting the certification requirements for a range of national security space missions,” Panzenhagen said in a statement.

The Space Force is eager for Vulcan to become operational. Some of the military’s most critical reconnaissance, communications, and missile warning satellites are slated to fly on Vulcan rockets.

Ramping up

Going into Friday’s test flight, ULA and the Space Force hoped to launch one or two more Vulcan rockets by the end of the year, both with US Space Force payloads. The timing of the next Vulcan launch, assuming the Space Force certifies the new rocket, will likely hinge on the outcome of the investigation into the booster anomaly.

ULA has already transported all major components of the next Vulcan rocket from its factory in Alabama to Cape Canaveral for final launch preparations. The company has a backlog of 69 Vulcan flights, counting missions for the Space Force, the National Reconnaissance Office, Amazon’s Kuiper network, and Sierra Space’s Dream Chaser spaceplane to resupply the International Space Station.

In a prelaunch briefing with reporters, Bruno said ULA aims to launch up to 20 times next year. Roughly half of that number will be Vulcan flights, and the rest will be Atlas V rockets, which ULA is retiring in favor of Vulcan.

There are 15 Atlas V rockets left to fly, primarily for Amazon and Boeing’s Starliner crew capsule. The nozzle failure Friday may also affect the schedule for Atlas V launches because the soon-to-retire rocket uses a similar booster design from Northrop Grumman.

ULA eventually wants to launch up to 25 Vulcan rockets per year from its launch pads at Cape Canaveral and at Vandenberg Space Force Base, California. The launch provider is outfitting a second assembly building in Florida to stack Vulcan rockets, a capability that will shorten the time between liftoffs. ULA is modifying its Atlas V launch pad in California to support Vulcan flights there next year.

ULA announced the Vulcan rocket in 2015 to replace the Atlas V and Delta IV rockets, which had stellar success records but were not cost-competitive with SpaceX’s partially reusable Falcon 9. The Atlas V also uses a Russian main engine, a situation that became politically untenable after Russia’s annexation of Crimea in 2014, and more so after the Russian invasion of Ukraine in 2022. The final Russian engines for the Atlas V arrived in the United States in 2021.

The Vulcan rocket is somewhat less expensive than the Atlas V, and significantly cheaper than the Delta IV, but still more costly than SpaceX’s Falcon 9. There is a closer price parity between Vulcan and SpaceX’s Falcon Heavy rocket.

Bruno hinted at the cost of developing the rocket in his roundtable discussion with reporters earlier this week.

“Developing a rocket, and then the infrastructure to develop a new space launch vehicle, the rule of thumb is it costs you somewhere between $5 billion and $7 billion,” Bruno said. “Vulcan is not outside the rule of thumb.”

The second flight of United Launch Alliance’s Vulcan rocket, planned for Friday morning, has a primary goal of validating the launcher’s reliability for delivering critical US military satellites to orbit.

Tory Bruno, ULA’s chief executive, told reporters Wednesday that he is “supremely confident” the Vulcan rocket will succeed in accomplishing that objective. The Vulcan’s second test flight, known as Cert-2, follows a near-flawless debut launch of ULA’s new rocket on January 8.

“As I come up on Cert-2, I’m pretty darn confident I’m going to have a good day on Friday, knock on wood,” Bruno said. “These are very powerful, complicated machines.”

The Vulcan launcher, a replacement for ULA’s Atlas V and Delta IV rockets, is on contract to haul the majority of the US military’s most expensive national security satellites into orbit over the next several years. The Space Force is eager to certify Vulcan to launch these payloads, but military officials want to see two successful test flights before committing one of its satellites to flying on the new rocket.

If Friday’s test flight goes well, ULA is on track to launch at least one—and perhaps two—operational missions for the Space Force by the end of this year. The Space Force has already booked 25 launches on ULA’s Vulcan rocket for military payloads and spy satellites for the National Reconnaissance Office. Including the launch Friday, ULA has 70 Vulcan rockets in its backlog, mostly for the Space Force, the NRO, and Amazon’s Kuiper satellite broadband network.

The Vulcan rocket is powered by two methane-fueled BE-4 engines produced by Jeff Bezos’ space company Blue Origin, and ULA can mount zero, two, four, or six strap-on solid rocket boosters from Northrop Grumman around the Vulcan’s first stage to propel heavier payloads to space. The rocket’s Centaur V upper stage is fitted with a pair of hydrogen-burning RL10 engines from Aerojet Rocketdyne.

The second Vulcan rocket will fly in the same configuration as the first launch earlier this year, with two strap-on solid-fueled boosters. The only noticeable modification to the rocket is the addition of some spray-on foam insulation around the outside of the first stage methane tank, which will keep the cryogenic fuel at the proper temperature as Vulcan encounters aerodynamic heating on its ascent through the atmosphere.

“This will give us just over one second more usable propellant,” Bruno wrote on X.

There is one more change from Vulcan’s first launch, which boosted a commercial lunar lander for Astrobotic on a trajectory toward the Moon. This time, there are no real spacecraft on the Vulcan rocket. Instead, ULA mounted a dummy payload to the Centaur V upper stage to simulate the mass of a functioning satellite.

ULA originally planned to launch Sierra Space’s first Dream Chaser spaceplane on the second Vulcan rocket. But the Dream Chaser won’t be ready to fly its first mission to resupply the International Space Station until next year. Under pressure from the Pentagon, ULA decided to move ahead with the second Vulcan launch without a payload at the company’s own expense, which Bruno tallied in the “high tens of millions of dollars.”

Heliocentricity

The test flight will begin with liftoff from Cape Canaveral Space Force Station, Florida, during a three-hour launch window opening at 6 am EDT (10: 00 UTC). The 202-foot-tall (61.6-meter) Vulcan rocket will head east over the Atlantic Ocean, shedding its boosters, first stage, and payload fairing in the first few minutes of flight.

The Centaur upper stage will fire its RL10 engines two times, completing the primary mission within about 35 minutes of launch. The rocket will then continue on for a series of technical demonstrations before ending up on an Earth escape trajectory into a heliocentric orbit around the Sun.

“We have a number of experiments that we’re conducting that are really technology demonstrations and measurements that are associated with our high-performance, longer-duration version of Centaur V that we’ll be introducing in the future,” Bruno said. “And these will help us go a little bit faster on that development. And, of course, because we don’t have an active spacecraft as a payload, we also have more instrumentation that we’re able to use for just characterizing the vehicle.”

ULA engineers have worked on the design of a long-lived upper stage for more than a decade. Their vision was to develop an upper stage fed by super-efficient cryogenic liquid hydrogen and liquid oxygen propellants that could generate its own power and operate in space for days, weeks, or longer rather than an upper stage’s usual endurance limit of several hours. This would allow the rocket to not only deliver satellites into bespoke high-altitude orbits but also continue on to release more payloads at different altitudes or provide longer-term propulsion in support of other missions.

The concept was called the Advanced Cryogenic Evolved Stage (ACES). ULA’s corporate owners, Boeing and Lockheed Martin, never authorized the full development of ACES, and the company said in 2020 that it was no longer pursuing the ACES concept.

The Centaur V upper stage currently used on the Vulcan rocket is a larger version of the thin-walled, pressure-stabilized Centaur upper stage that has been flying since the 1960s. Bruno said the Centaur V design, as it is today, offers as much as 12 hours of operating life in space. This is longer than any other existing rocket using cryogenic propellants, which can boil off over time.

ULA’s chief executive still harbors an ambition for regaining some of the same capabilities promised by ACES.

“What we are looking to do is to extend that by orders of magnitude,” Bruno said. “And what that would allow us to do is have a in-space transportation capability for in-space mobility and servicing and things like that.”

Space Force leaders have voiced a desire for future spacecraft to freely maneuver between different orbits, a concept the military calls “dynamic space operations.” This would untether spacecraft operations from fuel limitations and eventually require the development of in-orbit refueling, propellant depots, or novel propulsion technologies.

No one has tried to store large amounts of super-cold propellants in space for weeks or longer. Accomplishing this is a non-trivial thermal problem, requiring insulation to keep heat from the Sun from reaching the liquid cryogenic propellant, stored at temperatures of several hundred degrees below zero.

Bruno hesitated to share details of the experiments ULA plans for the Centaur V upper stage on Friday’s test flight, citing proprietary concerns. He said the experiments will confirm analytical models about how the upper stage performs in space.

“Some of these are devices, some of these are maneuvers because maneuvers make a difference, and some are related to performance in a way,” he said. “In some cases, those maneuvers are helping us with the thermal load that tries to come in and boil off the propellants.”

Eventually, ULA would like to eliminate hydrazine attitude control fuel and battery power from the Centaur V upper stage, Bruno said Wednesday. This sounds a lot like what ULA wanted to do with ACES, which would have used an internal combustion engine called Integrated Vehicle Fluids (IVF) to recycle gasified waste propellants to pressurize its propellant tanks, generate electrical power, and feed thrusters for attitude control. This would mean the upper stage wouldn’t need to rely on hydrazine, helium, or batteries.

ULA hasn’t talked much about the IVF system in recent years, but Bruno said the company is still developing it. “It’s part of all of this, but that’s all I will say, or I’ll start revealing what all the gadgets are.”

George Sowers, former vice president and chief scientist at ULA, was one of the company’s main advocates for extending the lifetime of upper stages and developing technologies for refueling and propellant depot. He retired from ULA in 2017 and is now a professor at the Colorado School of Mines and an independent aerospace industry consultant.

In an interview with Ars earlier this year, Sowers said ULA solved many of the problems with keeping cryogenic propellants at the right temperature in space.

“We had a lot of data on boil-off, just from flying Centaurs all the way to geosynchronous orbit, which doesn’t involve weeks, but it involves maybe half a day or so, which is plenty of time to get all the temperatures to stabilize at deep space levels,” Sowers said. “So you have to understand the heat transfer very well. Good models are very important.”

ULA experimented with different types of insulation and vapor cooling, which involves taking cold gas that boiled off of cryogenic fuel and blowing it on heat penetration points into the tanks.

“There are tricks to managing boil-off,” he said. “One of the tricks is that you never want to boil oxygen. You always want to boil hydrogen. So you size your propellant tanks and your propellant loads, assuming you’re going to have that extra hydrogen boil-off. Then what you can do is use the hydrogen to keep the oxygen cold to keep it from boiling.

“The amount of heat that you can reject by boiling off one kilogram of hydrogen is about five times what you would reject by boiling off one kilogram of oxygen. So those are some of the thermodynamic tricks,” Sowers said. “The way ULA accomplished that is by having a common bulkhead, so the hydrogen tank and the oxygen tank are in thermal contact. So hydrogen keeps the oxygen cold.”

ULA’s experiments showed it could get the hydrogen boil-off rate down to about 10 percent per year, based on thermodynamic models calibrated by data from flying older versions of the Centaur upper stage on Atlas V rockets, according to Sowers.

“In my mind, that kind of cemented the idea that distribution depots and things like that are very well in hand without having to have exotic cryocoolers, which tend to use a lot of power,” Sowers said. “It’s about efficiency. If you can do it passively, you don’t have to expend energy on cryocoolers.”

“We’re going to go to days, and then we’re going to go to weeks, and then we think it’s possible to take us to months,” Bruno said. “That’s a game changer.”

However, ULA’s corporate owners haven’t yet fully bought into this vision. Bruno said the Vulcan rocket and its supporting manufacturing and launch infrastructure cost between $5 billion and $7 billion to develop. ULA also plans to eventually recover and reuse BE-4 main engines from the Vulcan rocket, but that is still at least several years away.

But ULA is reportedly up for sale, and a well-capitalized buyer might find the company’s long-duration cryogenic upper stage more attractive and worth the investment.

“There’s a whole lot of missions that enables,” Bruno said. “So that’s a big step in capability, both for the United States and also commercially.”

NASA is ready to start buying Vulcan rockets from United Launch Alliance

Full stack —

The second test flight of the Vulcan rocket is scheduled for liftoff on October 4.

Stephen Clark – Sep 24, 2024 5: 14 pm UTC

The first stage of ULA's second Vulcan rocket was raised onto its launch platform August 11 at Cape Canaveral Space Force Station, Florida. — Enlarge / The first stage of ULA’s second Vulcan rocket was raised onto its launch platform August 11 at Cape Canaveral Space Force Station, Florida.

United Launch Alliance is free to compete for NASA contracts with its new Vulcan rocket after a successful test flight earlier this year, ending a period where SpaceX was the only company competing for rights to launch the agency’s large science missions.

For several years, ULA was unable to bid for NASA launch contracts after the company sold all of its remaining Atlas V rockets to other customers, primarily for Amazon’s Project Kuiper Internet network. ULA could not submit its new Vulcan rocket, which will replace the Atlas V, for NASA to consider in future launch contracts until the Vulcan completed at least one successful flight, according to Tim Dunn, senior launch director at NASA’s Launch Services Program.

The Vulcan rocket’s first certification flight on January 8, called Cert-1, was nearly flawless, demonstrating the launcher’s methane-fueled BE-4 engines built by Blue Origin and an uprated twin-engine Centaur upper stage. A second test flight, known as Cert-2, is scheduled to lift off no earlier than October 4 from Cape Canaveral Space Force Station, Florida. Assuming the upcoming launch is as successful as the first one, the US Space Force aims to launch its first mission on a Vulcan rocket by the end of the year.

The Space Force has already booked 25 launches on ULA’s Vulcan rocket for military payloads and spy satellites for the National Reconnaissance Office. But these missions won’t launch until Vulcan completes its second test flight, clearing the way for the Space Force to certify ULA’s new rocket for national security missions.

Back in the game

NASA’s Launch Services Program (LSP) is responsible for selecting and overseeing launch providers for the agency’s robotic science missions. NASA’s near-term options for launching large missions include SpaceX’s Falcon 9 and Falcon Heavy rockets, ULA’s Vulcan, and Blue Origin’s New Glenn launcher.

However, only SpaceX’s rockets have been available for NASA bids since 2021, when ULA sold all of its remaining Atlas V rockets to Amazon. For example, ULA did not submit proposals for the launch of a GOES weather satellite or NASA’s Roman Space Telescope, two of the more lucrative launch contracts the agency has awarded in the last couple of years. NASA selected SpaceX’s Falcon Heavy, the only eligible rocket, for both missions.

This is a notable role reversal for SpaceX and ULA, a 50-50 joint venture between Boeing and Lockheed Martin that was the sole launch provider for large NASA science missions and military satellites for nearly a decade. SpaceX launched its first mission for NASA’s Launch Services Program in January 2016.

The situation changed with the first flight of the Vulcan rocket in January.

“They certainly demonstrated a huge success earlier this year flying Cert-1,” Dunn told Ars in an interview. “They needed a successful flight to then bid for future missions, so that allowed them to be in a position to bid on our missions.”

NASA has not yet formally certified the Vulcan rocket to launch one of the agency’s science missions, but that would not stop NASA from selecting Vulcan for a contract. Some of NASA’s next big science missions up for launch contract awards include the nuclear-powered Dragonfly mission to explore Saturn’s moon Titan and an asteroid-hunting telescope named NEO Surveyor.

The second Vulcan flight next month will move ULA’s rocket toward certification by the Space Force and NASA.

“A second Cert flight that will then demonstrate a few other capabilities of the rocket allows more data for our certification team that is working in concert with the US Space Force’s certification team,” Dunn said. “We’re doing a lot of shared, intergovernmental collaborations in the certification work, so it allows us all more data, more confidence in that launch vehicle to meet all the needs that we believe we will have in the coming decade-plus.”

Blue Origin’s New Glenn could also compete for contracts to launch NASA’s larger, more expensive missions after it completes at least one successful flight. Blue Origin is currently eligible for bids to launch NASA’s smaller missions, such as the ESCAPADE mission to Mars already assigned to New Glenn. NASA is willing to accept more risk for launching these types of lower-cost missions.

ULA capped off the assembly of its second Vulcan rocket at Cape Canaveral on Saturday when technicians lifted the launcher’s payload fairing atop Vulcan’s first-stage booster and Centaur upper stage. For its second launch, Vulcan will carry a dummy payload instead of a real satellite. The second Vulcan flight was initially supposed to launch Sierra Space’s first Dream Chaser spaceplane to the International Space Station, but Dream Chaser isn’t ready, and the Space Force is eager for ULA to get moving and finish the certification process.

The head of Space Systems Command, Lt. Gen. Philip Garrant, told Ars last week that he is “optimistic” ULA will be in a position to launch its first Space Force missions with the Vulcan rocket by the end of this year. ULA has already delivered Vulcan rocket parts for the next two missions to Cape Canaveral, but the Cert-2 launch needs to go off without a hitch.

“We’re working very closely with ULA on that, as well as the manifest for the following missions,” Garrant said. “All of the rocket parts are at the launch locations, ready to go, but clearly the priority is the certification flight and making sure that the launch vehicle is certified. But we are optimistic that we’re going to get those launches off.”

Rocket Report: ULA is losing engineers; SpaceX is launching every two days

Every other day —

The first missions of Stoke Space’s reusable Nova rocket will fly in expendable mode.

Stephen Clark – Aug 16, 2024 11: 00 am UTC

Enlarge / A Falcon 9 booster returns to landing at Cape Canaveral Space Force Station following a launch Thursday with two WorldView Earth observation satellites for Maxar.

Welcome to Edition 7.07 of the Rocket Report! SpaceX has not missed a beat since the Federal Aviation Administration gave the company a green light to resume Falcon 9 launches after a failure last month. In 19 days, SpaceX has launched 10 flights of the Falcon 9 rocket, taking advantage of all three of its Falcon 9 launch pads. This is a remarkable cadence in its own right, but even though it’s a small sample size, it is especially impressive right out of the gate after the rocket’s grounding.

A quick turnaround for Rocket Lab. Rocket Lab launched its 52nd Electron rocket on August 11 from its private spaceport on Mahia Peninsula in New Zealand, Space News reports. The company’s light-class Electron rocket deployed a small radar imaging satellite into a mid-inclination orbit for Capella Space. This was the shortest turnaround between two Rocket Lab missions from its primary launch base in New Zealand, coming less than nine days after an Electron rocket took off from the same pad with a radar imaging satellite for the Japanese company Synspective. Capella’s Acadia 3 satellite was originally supposed to launch in July, but Capella requested a delay to perform more testing of its spacecraft. Rocket Lab swapped its place in the Electron launch sequence and launched the Synspective mission first.

Now, silence at the launch pad … Rocket Lab hailed the swap as an example of the flexibility provided by Electron, as well as the ability to deliver payloads to specific orbits that are not feasible with rideshare missions, according to Space News. For this tailored launch service, Rocket Lab charges a premium launch price over the price of launching a small payload on a SpaceX rideshare mission. However, SpaceX’s rideshare launches gobble up the lion’s share of small satellites within Rocket Lab’s addressable market. On Friday, a Falcon 9 rocket is slated to launch 116 small payloads into polar orbit. Rocket Lab, meanwhile, projects just one more launch before the end of September and expects to perform 15 to 18 Electron launches this year, a record for the company but well short of the 22 it forecasted earlier in the year. Rocket Lab says customer readiness is the reason it will be far short of projections.

Defense contractors teaming up on solid rockets. Lockheed Martin and General Dynamics are joining forces to kickstart solid rocket motor production, announcing a strategic teaming agreement today that could see new motors roll off the line as early as 2025, Breaking Defense reports. The new agreement could position a third vendor to enter into the ailing solid rocket motor industrial base, which currently only includes L3Harris subsidiary Aerojet Rocketdyne and Northrop Grumman in the United States. Both companies have struggled to meet demands from weapons makers like Lockheed and RTX, which are in desperate need of solid rocket motors for products such as Javelin or the PAC-3 missiles used by the Patriot missile defense system.

Pressure from startups … Demand for solid rocket motors has skyrocketed since Russia’s invasion of Ukraine as the United States and its partners sought to backfill stocks of weapons like Javelin and Stinger, as well as provide motors to meet growing needs in the space domain. Although General Dynamics has kept its interest in the solid rocket motor market quiet until now, several defense tech startups, such as Ursa Major Technologies, Anduril, and X-Bow Systems, have announced plans to enter the market.

Going polar with crew. SpaceX will fly the first human spaceflight over the Earth’s poles, possibly before the end of this year, Ars reports. The private Crew Dragon mission will be led by a Chinese-born cryptocurrency entrepreneur named Chun Wang, and he will be joined by a polar explorer, a roboticist, and a filmmaker whom he has befriended in recent years. The “Fram2” mission, named after the Norwegian research ship Fram, will launch into a polar corridor from SpaceX’s launch facilities in Florida and fly directly over the north and south poles. The three- to five-day mission is being timed to fly over Antarctica near the summer solstice in the Southern Hemisphere, to afford maximum lighting.

Wang’s inclination is Wang’s prerogative … Wang told Ars he wanted to try something new, and flying a polar mission aligned with his interests in cold places on Earth. He’s paying the way on a commercial basis, and SpaceX in recent years has demonstrated it can launch satellites into polar orbit from Cape Canaveral, Florida, something no one had done in more than 50 years. The highest-inclination flight ever by a human spacecraft was the Soviet Vostok 6 mission in 1963 when Valentina Tereshkova’s spacecraft reached 65.1 degrees. Now, Fram2 will fly repeatedly and directly over the poles.

Starship down under —

Elon Musk doesn’t expect the next Starship test flight to occur before late August.

Stephen Clark – Aug 2, 2024 12: 39 pm UTC

Welcome to Edition 7.05 of the Rocket Report! The Federal Aviation Administration grounded SpaceX’s Falcon 9 rocket for 15 days after a rare failure of its upper stage earlier this month. The FAA gave the green light for Falcon 9 to return to flight July 25, and within a couple of days, SpaceX successfully launched three missions from three launch pads. There’s a lot on Falcon 9’s to-do list, so we expect SpaceX to quickly return to form with several flights per week.

Big delay for a reusable rocket testbed. The French space agency, CNES, has revealed that the inaugural test flight of its Callisto reusable rocket demonstrator will not take place until late 2025 or early 2026, European Spaceflight reports. CNES unveiled an updated website for the Callisto rocket program earlier this month, showing the test rocket has been delayed from a debut launch later this year to until late 2025 or early 2026. The Callisto rocket is designed to test techniques and technologies required for reusable rockets, such as vertical takeoff and vertical landing, with suborbital flights from the Guiana Space Center in South America.

Cooperative action … Callisto, which stands for Cooperative Action Leading to Launcher Innovation in Stage Toss-back Operations, is a joint project between CNES, German space agency DLR, and JAXA, the Japanese space agency. It will stand 14 meters (46 feet) tall and weigh about 4 metric tons (8,800 pounds), with an engine supplied by Japan. Callisto is one of several test projects in Europe aiming to pave the way for a future reusable rocket. (submitted by EllPeaTea and Ken the Bin)

Small step for Themis. Another European project established to demonstrate reusable rocket tech is making slow progress toward a first flight. The Themis project, funded by the European Space Agency, is similar in purpose to the Callisto testbed discussed above. This week, the German aerospace manufacturing company MT Aerospace announced it has begun testing a demonstrator of the landing legs that will be used aboard the Themis reusable booster, European Spaceflight reports. The landing legs for Themis are made of carbon ﬁber-reinforced plastic composites, and the initial test demonstrated good deployment and showed it would withstand the impact energy of landing.

Also delayed … Like Callisto, Themis is facing delays in getting to the launch pad. ArianeGroup, the ESA-selected Themis prime contractor, had been expected to conduct an initial hop test of the demonstrator before the end of 2024. However, officials have announced the initial hop tests won’t happen until sometime next year. The Themis booster is intended to eventually become the first stage booster for an orbital-class partially reusable rocket being developed by MaiaSpace, a subsidiary of ArianeGroup.

Falcon 9 is flying again. A SpaceX Falcon 9 rocket returned to flight on July 27, barely two weeks after an upper stage failure ended a streak of more than 300 consecutive successful launches, Ars reports. By some measures this was an extremely routine mission—it was, after all, SpaceX’s 73rd launch of this calendar year. And like many other Falcon 9 launches this year, the “Starlink 10-9” mission carried 23 of the broadband Internet satellites into orbit. However, after a rare failure earlier this month, this particular Falcon 9 rocket was making a return-to-flight for the company and attempting to get the world’s most active booster back into service.

Best part is no part … The Falcon 9 successfully deployed its payload of Starlink satellites about an hour after lifting off from NASA’s Kennedy Space Center in Florida. Later in the weekend, SpaceX launched two more Starlink missions on Falcon 9 rockets from Florida and California, notching three flights in less than 28 hours. The launch failure on the previous Falcon 9 launch was caused by a liquid oxygen leak on the upper stage, which led to a “hard start” on the upper stage engine when it attempted to reignite in flight. Engineers and technicians were quickly able to pinpoint the cause of the leak, a crack in a “sense line” for a pressure sensor attached to the vehicle’s liquid oxygen system.

Atlas V’s NSSL era is over. United Launch Alliance delivered a classified US military payload to orbit Tuesday for the last time with an Atlas V rocket, ending the Pentagon’s use of Russian rocket engines as national security missions transition to all-American launchers, Ars reports. This was the 101st launch of an Atlas V rocket since its debut in 2002, and the 58th and final Atlas V mission with a US national security payload since 2007. The Atlas V is powered by an RD-180 main engine made in Russia, and with a little prodding from SpaceX (via a lawsuit) and Congress, the Pentagon started making moves to end its reliance on the RD-180 a decade ago.

Other options available … The RD-180 never failed on a National Security Space Launch (NSSL) mission using the Atlas V rocket, but its use became politically untenable after Russia’s annexation of Crimea in 2014, which predated Russia’s full-scale invasion of Ukraine eight years later. SpaceX began launching US military missions in 2018, and ULA debuted its new Vulcan rocket in January. Assuming a successful second test flight of Vulcan in September, ULA’s next-generation rocket has a good shot at launching its first national security mission by the end of the year. The Space Force’s policy is to maintain at least two independent launch vehicles capable of flying military payloads into orbit. Vulcan and SpaceX’s Falcon rocket family fulfill that requirement, so the military no longer needs the Atlas V. However, 15 more Atlas V rockets remain in ULA’s inventory for future commercial flights.

Crackdown at the Cape. While this week’s landmark launch of the Atlas V rocket is worthy of celebration, there’s a new ULA policy that deserves ridicule, Ars reports. Many of the spectacular photos of rocket launches shared on social media come from independent photographers, who often make little to no money working for an established media organization. Instead, they rely on sales of prints to recoup at least some of their expenses for gas, food, and camera equipment needed to capture these images, which often serve as free publicity for launch providers like ULA. Last month, ULA announced it will no longer permit these photographers to set up remote cameras at their launch pads if they sell their images independently. This new policy was in place for the Atlas V launch from Cape Canaveral, Florida, on Tuesday morning.

But why? … “ULA will periodically confirm editorial publication for media participating in remote camera placement,” ULA stated in an email distributed to photographers last month. “If publication does not occur, or photos are sold outside of editorial purposes, privileges to place remote cameras may be revoked.” To the photographers who spend many hours preparing their equipment, waiting to set up and remove cameras, and persevering through scrubs and more, it seemed like a harsh judgment. And nobody knows why it happened. ULA has offered no public comment about the new policy, and the company did not respond to questions from Ars about the agreement.

Astroscale achieves a first in orbit. There are more than 2,000 mostly intact dead rockets circling the Earth, but until this year, no one ever launched a satellite to go see what one looked like after many years of tumbling around the planet, Ars reports. A Japanese company named Astroscale launched a small satellite in February to chase down the derelict upper stage from a Japanese H-IIA rocket. Astroscale’s ADRAS-J spacecraft arrived near the H-IIA upper stage in April, and the company announced this week that its satellite has now completed two 360-degree fly-arounds of the rocket. This is the first time a satellite has maneuvered around an actual piece of space junk, and it offers an unprecedented snapshot of how an abandoned rocket holds up to 15 years in the harsh environment of space.

Prepping for the future … Astroscale’s ADRAS-J mission is partially funded by the Japan Aerospace Exploration Agency (JAXA). Astroscale and JAXA also have a contract for a follow-up mission named ADRAS-J2, which will attempt to link up with the same H-IIA rocket and steer it on a trajectory to burn up in Earth’s atmosphere. This would be the first demonstration of active debris removal, a concept pursued by Astroscale and other companies to help clear space junk out of low-Earth orbit.

An update on Ariane 6. The European Space Agency has released its first update on the results from the first flight of the Ariane 6 rocket since its launch July 9. Europe’s new flagship rocket had a mostly successful inaugural test flight. Its first stage, solid rocket boosters, and upper stage performed as expected for the first phase of the flight, delivering eight small satellites into an on-target orbit. The launch pad at the Guiana Space Center in South America also held up to the violent environment of launch, ESA said.

Still investigating … However, the final phase of the mission didn’t go according to plan. The upper stage’s Vinci engine was supposed to reignite for a third time on the test flight to deorbit the rocket, which would have released two small reentry capsules on technology demonstration missions to test heat shield technologies. This didn’t happen. An Auxiliary Propulsion Unit, which is a small engine to provide additional bursts of thrust and pressurize the upper stage’s propellant tanks, shut down shortly after startup ahead of the third burn of the primary Vinci engine. “This meant the Vinci engine’s third boost could not take place,” ESA said. “Analysis of the APU’s behavior is ongoing and further information will be made available as soon as possible, while the next task force update is expected in September.” (submitted by Ken the Bin)

Room to grow at Starbase. SpaceX has since launched Starship four times from its launch site in South Texas, known as Starbase, and is planning a fifth launch within the next two months, Ars reports. However, as it continues to test Starship and make plans for regular flights, SpaceX will need a higher flight rate. This is especially true as the company is unlikely to activate additional launch pads for Starship in Florida until at least 2026. To that end, SpaceX has asked the FAA for permission for up to 25 flights a year from South Texas, as well as the capability to land both the Starship upper stage and Super Heavy booster stage back at the launch site.

The answer is probably yes … On Monday, the FAA signaled that it is inclined to grant this request. The agency released a draft assessment indicating that its extensive 2022 analysis of Starship launch activities on the environment, wildlife, local communities, and more was sufficient to account for SpaceX’s proposal for more launches. There is more to do for this conclusion to become official, including public meetings and a public comment period this month.

SpaceX eyes Australia. SpaceX is in talks with US and Australian officials to land and recover one of its Starship rockets off Australia’s coast, a possible first step toward a bigger presence for Elon Musk’s company in the region as the two countries bolster security ties, Reuters reports. At the end of SpaceX’s fourth Starship test flight in June, the rocket made a controlled splashdown in the Indian Ocean hundreds of miles off the northwest coast of Australia. The discussions now underway are focused on the possibility of towing a future Starship vehicle from its splashdown point in the ocean to a port in Australia, where SpaceX engineers could inspect it and learn more about how it performed.

Eventually, it’ll come back to land … On the next Starship flight, currently planned for no earlier than late August, SpaceX plans to attempt to recover Starship’s giant Super Heavy booster using catch arms on the launch pad tower in Texas. On Sunday, Elon Musk told SpaceX and Tesla enthusiasts at an event called the “X Takeover” that it will take a few more flights for engineers to get comfortable returning the Starship itself to a landing onshore. “We want to be really confident that the ship heat shield is super robust and lands at the exact right location,” he said. “So before we try to bring the ship back to the launch site, we probably want to have at least three successful landings of the ship [at sea].” (submitted by Ken the Bin)

United Launch Alliance delivered a classified US military payload to orbit Tuesday for the last time with an Atlas V rocket, ending the Pentagon’s use of Russian rocket engines as national security missions transition to all-American launchers.

The Atlas V rocket lifted off from Cape Canaveral Space Force Station in Florida at 6: 45 am EDT (10: 45 UTC) Tuesday, propelled by a Russian-made RD-180 engine and five strap-on solid-fueled boosters in its most powerful configuration. This was the 101st launch of an Atlas V rocket since its debut in 2002, and the 58th and final Atlas V mission with a US national security payload since 2007.

The US Space Force’s Space Systems Command confirmed a successful conclusion to the mission, code-named USSF-51, on Tuesday afternoon. The rocket’s Centaur upper stage released the top secret USSF-51 payload about seven hours after liftoff, likely in a high-altitude geostationary orbit over the equator. The military did not publicize the exact specifications of the rocket’s target orbit.

“What a fantastic launch and a fitting conclusion for our last national security space Atlas V (launch),” said Walt Lauderdale, USSF-51 mission director at Space Systems Command, in a post-launch press release. “When we look back at how well Atlas V met our needs since our first launch in 2007, it illustrates the hard work and dedication from our nation’s industrial base. Together, we made it happen, and because of teams like this, we have the most successful and thriving launch industry in the world, bar none.”

RD-180’s long goodbye

The launch Tuesday morning was the end of an era born in the 1990s when US government policy allowed Lockheed Martin, the original developer of the Atlas V, to use Russian rocket engines during its first stage. There was a widespread sentiment in the first decade after the fall of the Soviet Union that the United States and other Western nations should partner with Russia to keep the country’s aerospace workers employed and prevent “rogue states” like Iran or North Korea from hiring them.

At the time, the Pentagon was procuring new rockets to replace legacy versions of the Atlas, Delta, and Titan rocket families, which had been in service since the late 1950s or early 1960s.

Ultimately, the Air Force chose Lockheed Martin’s Atlas V and Boeing’s Delta IV rocket for development in 1998. The Atlas V, with its Russian main engine, was somewhat less expensive than the Delta IV and the more successful of the two designs. After Tuesday’s launch, 15 more Atlas V rockets are booked to fly payloads for commercial customers and NASA, mainly for Amazon’s Kuiper network and Boeing’s Starliner crew spacecraft. The 45th and final Delta IV launch occurred in April.

Boeing and Lockheed Martin merged their rocket divisions in 2006 to form a 50-50 joint venture named United Launch Alliance, which became the sole contractor certified to carry large US military satellites to orbit until SpaceX started launching national security missions in 2018.

SpaceX filed a lawsuit in 2014 to protest the Air Force’s decision to award ULA a multibillion-dollar sole-source contract for 36 Atlas V and Delta IV rocket booster cores. The litigation started soon after Russia’s military occupation and annexation of Crimea, which prompted US government sanctions on prominent Russian government officials, including Dmitry Rogozin, then Russia’s deputy prime minister and later the head of Russia’s space agency.

Rogozin, known for his bellicose but usually toothless rhetoric, threatened to halt exports of RD-180 engines for US military missions on the Atlas V. That didn’t happen until Russia finally stopped engine exports to the United States in 2022, following its full-scale invasion of Ukraine. At that point, ULA already had all the engines it needed to fly out all of its remaining Atlas V rockets. This export ban had a larger effect on Northrop Grumman’s Antares rocket, which also used Russian engines, forcing the development of a brand new first stage booster with US engines.

The SpaceX lawsuit, Russia’s initial military incursions into Ukraine in 2014, and the resulting sanctions marked the beginning of the end for the Atlas V rocket and ULA’s use of the Russian RD-180 engine. The dual-nozzle RD-180, made by a Russian company named NPO Energomash, consumes kerosene and liquid oxygen propellants and generates 860,000 pounds of thrust at full throttle.
