NASA has spent $450 million designing and building a first-of-its-kind robot to drive into eternally dark craters at the Moon’s south pole, but the agency announced Wednesday it will cancel the rover due to delays and cost overruns.

“NASA intends to discontinue the VIPER mission,” said Nicky Fox, head of the agency’s science mission directorate. “Decisions like this are never easy, and we haven’t made this one, in any way, lightly. In this case, the projected remaining expenses for VIPER would have resulted in either having to cancel or disrupt many other missions in our Commercial Lunar Payload Services (CLPS) line.”

NASA has terminated science missions after development delays and cost overruns before, but it’s rare to cancel a mission with a spacecraft that is already built.

The Volatiles Investigating Polar Exploration Rover (VIPER) mission was supposed to be a robotic scout for NASA’s Artemis program, which aims to return astronauts to the lunar surface in the next few years. VIPER was originally planned to launch in late 2023 and was slated to fly to the Moon aboard a commercial lander provided by Pittsburgh-based Astrobotic, which won a contract from NASA in 2020 to deliver the VIPER rover to the lunar surface. Astrobotic is one of 14 companies in the pool of contractors for NASA’s CLPS program, with the goal of transporting government-sponsored science payloads to the Moon.

But VIPER has been delayed at least two years—the most recent schedule projected a launch in September 2025—causing its cost to grow from $433 million to more than $609 million. The ballooning costs automatically triggered a NASA review to determine whether to proceed with the mission or cancel it. Ultimately, officials said they determined NASA couldn’t pay the extra costs for VIPER without affecting other Moon missions.

“Therefore, we’ve made the decision to forego this particular mission, the VIPER mission, in order to be able to sustain the entire program,” Fox said.

“We’re disappointed,” said John Thornton, CEO of Astrobotic. “It’s certainly difficult news… VIPER has been a great team to work with, and we’re disappointed we won’t get the chance to fly them to the Moon.”

NASA said it will consider “expressions of interest” submitted by US industry and international partners by August 1 for use of the existing VIPER rover at no cost to the government. If NASA can’t find anyone to take over VIPER who can pay to get it to the Moon, the agency plans to disassemble the rover and harvest instruments and components for future lunar missions.

Scientists were dismayed by VIPER’s cancellation.

“It’s absurd, to be honest with you,” said Clive Neal, a planetary geologist at the University of Notre Dame. “It made no sense to me in terms of the economics. You’re canceling a mission that is complete, built, ready to go. It’s in the middle of testing.”

“This is a bad mistake,” wrote Phil Metzger, a planetary physicist at the University of Central Florida, in a post on X. “This was the premier mission to measure lateral and vertical variations of lunar ice in the soil. It would have been revolutionary. Other missions don’t replace what is lost here.”

Built with nowhere to go

Engineers at NASA’s Johnson Space Center in Houston finished assembling the VIPER rover last month, and managers gave approval to put the craft through environmental testing to make sure VIPER could withstand the acoustics and vibrations of launch and the extreme temperature swings it would encounter in space.

Instead, NASA has canceled the mission after spending $450 million to get it to this point. “This is a very tough decision, but it is a decision based on budgetary concerns in a very constrained budget environment,” Fox told reporters Wednesday.

VIPER is about the size of a golf cart, with four wheels, headlights, a drill, and three science instruments to search for water ice in depressions near the Moon’s south pole that have been shaded from sunlight for billions of years. This has allowed these so-called permanently shadowed regions to become cold traps, allowing water ice to accumulate at or near the surface, where it could be accessible for future astronauts to use as drinking water or an oxygen source or to convert into electricity and rocket fuel.

But first, scientists need to know exactly where the water is located and how easy it is to reach. VIPER was supposed to be the next step in mapping resources on the Moon, providing ground truth measurements to corroborate remote sensing data from satellites in lunar orbit.

But late parts deliveries delayed construction of the VIPER rover, and in 2022, NASA ordered additional testing of Astrobotic’s Griffin lunar lander to improve the chances of a successful landing with VIPER. This delayed VIPER’s launch from late 2023 until late 2024, and at the beginning of this year, more supply chain issues with the VIPER rover and the Griffin lander pushed back the launch until September 2025.

This most recent delay raised the projected cost of VIPER more than 30 percent over the original cost of the mission, prompting a NASA termination review. While the rover is now fully assembled, NASA still needed to put it through a lengthy series of tests, complete development of the ground systems to control VIPER on the Moon, and deliver the craft to Astrobotic for integration onto the Griffin lander.

The remaining work to complete VIPER and operate it for 100 days on the lunar surface would have cost around $84 million, according to Kearns.

SpaceX’s unmatched streak of perfection with the Falcon 9 rocket is over

SpaceX

A SpaceX Falcon 9 rocket suffered an upper stage engine failure and deployed a batch of Starlink Internet satellites into a perilously low orbit after launch from California Thursday night, the first blemish on the workhorse launcher’s record in more than 300 missions since 2016.

Elon Musk, SpaceX’s founder and CEO, posted on X that the rocket’s upper stage engine failed when it attempted to reignite nearly an hour after the Falcon 9 lifted off from Vandenberg Space Force Base, California, at 7: 35 pm PDT (02: 35 UTC).

Frosty evidence

After departing Vandenberg to begin SpaceX’s Starlink 9-3 mission, the rocket’s reusable first stage booster propelled the Starlink satellites into the upper atmosphere, then returned to Earth for an on-target landing on a recovery ship parked in the Pacific Ocean. A single Merlin Vacuum engine on the rocket’s second stage fired for about six minutes to reach a preliminary orbit.

A few minutes after liftoff of SpaceX’s Starlink 9-3 mission, veteran observers of SpaceX launches noticed an unusual build-up of ice around the top of the Merlin Vacuum engine, which consumes a propellant mixture of super-chilled kerosene and cryogenic liquid oxygen. The liquid oxygen is stored at a temperature of several hundred degrees below zero.

Numerous chunks of ice fell away from the rocket as the upper stage engine powered into orbit, but the Merlin Vacuum, or M-Vac, engine appeared to complete its first burn as planned. A leak in the oxidizer system or a problem with insulation could lead to ice accumulation, although the exact cause, and its possible link to the engine malfunction later in flight, will be the focus of SpaceX’s investigation into the failure.

A second burn with the upper stage engine was supposed to raise the perigee, or low point, of the rocket’s orbit well above the atmosphere before releasing 20 Starlink satellites to continue climbing to their operational altitude with their own propulsion.

“Upper stage restart to raise perigee resulted in an engine RUD for reasons currently unknown,” Musk wrote in an update two hours after the launch. RUD (rapid unscheduled disassembly) is a term of art in rocketry that usually signifies a catastrophic or explosive failure.

“Team is reviewing data tonight to understand root cause,” Musk continued. “Starlink satellites were deployed, but the perigee may be too low for them to raise orbit. Will know more in a few hours.”

Telemetry from the Falcon 9 rocket indicated it released the Starlink satellites into an orbit with a perigee just 86 miles (138 kilometers) above Earth, roughly 100 miles (150 kilometers) lower than expected, according to Jonathan McDowell, an astrophysicist and trusted tracker of spaceflight activity. Detailed orbital data from the US Space Force was not immediately available.

Ripple effects

While ground controllers scramble to salvage the 20 Starlink satellites, SpaceX engineers began probing what went wrong with the second stage’s M-Vac engine. For SpaceX and its customers, the investigation into the rocket malfunction is likely the more pressing matter.

SpaceX could absorb the loss of 20 Starlink satellites relatively easily. The company’s satellite assembly line can produce 20 Starlink spacecraft in a few days. But the Falcon 9 rocket’s dependability and high flight rate have made it a workhorse for NASA, the US military, and the wider space industry. An investigation will probably delay several upcoming SpaceX flights.

The first in-flight failure for SpaceX’s Falcon rocket family since June 2015, a streak of 344 consecutive successful launches until tonight.

Depending on the cause of the problem and what SpaceX must do to fix it, it’s possible the company can recover from the upper stage failure and resume launching Starlink satellites soon. Most of SpaceX’s launches aren’t for external customers, but deploy satellites for the company’s own Starlink network. This gives SpaceX a unique flexibility to quickly return to flight with the Falcon 9 without needing to satisfy customer concerns.

The Federal Aviation Administration, which licenses all commercial space launches in the United States, will require SpaceX to conduct a mishap investigation before resuming Falcon 9 flights.

“The FAA will be involved in every step of the investigation process and must approve SpaceX’s final report, including any corrective actions,” an FAA spokesperson said. “A return to flight is based on the FAA determining that any system, process, or procedure related to the mishap does not affect public safety.”

Two crew missions are supposed to launch on SpaceX’s human-rated Falcon 9 rocket in the next six weeks, but those launch dates are now in doubt.

The all-private Polaris Dawn mission, commanded by billionaire Jared Isaacman, is scheduled to launch on a Falcon 9 rocket on July 31 from NASA’s Kennedy Space Center in Florida. Isaacman and three commercial astronaut crewmates will spend five days in orbit on a mission that will include the first commercial spacewalk outside their Crew Dragon capsule, using new pressure suits designed and built by SpaceX.

NASA’s next crew mission with SpaceX is slated to launch from Florida aboard a Falcon 9 rocket around August 19. This team of four astronauts will replace a crew of four who have been on the International Space Station since March.

Some customers, especially NASA’s commercial crew program, will likely want to see the results of an in-depth inquiry and require SpaceX to string together a series of successful Falcon 9 flights with Starlink satellites before clearing their own missions for launch. SpaceX has already launched 70 flights with its Falcon family of rockets since January 1, an average cadence of one launch every 2.7 days, more than the combined number of orbital launches by all other nations this year.

With this rapid-fire launch cadence, SpaceX could quickly demonstrate the fitness of any fixes engineers recommend to resolve the problem that caused Thursday night’s failure. But investigations into rocket failures often take weeks or months. It was too soon, early on Friday, to know the true impact of the upper stage malfunction on SpaceX’s launch schedule.

Welcome to Edition 7.01 of the Rocket Report! We’re compiling this week’s report a day later than usual due to the Independence Day holiday. Ars is beginning its seventh year publishing this weekly roundup of rocket news, and there’s a lot of it this week despite the holiday here in the United States. Worldwide, there were 122 launches that flew into Earth orbit or beyond in the first half of 2024, up from 91 in the same period last year.

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

Firefly launches its fifth Alpha flight. Firefly Aerospace placed eight CubeSats into orbit on a mission funded by NASA on the first flight of the company’s Alpha rocket since an upper stage malfunction more than half a year ago, Space News reports. The two-stage Alpha rocket lifted off from Vandenberg Space Force Base in California late Wednesday, two days after an issue with ground equipment aborted liftoff just before engine ignition. The eight CubeSats come from NASA centers and universities for a range of educational, research, and technology demonstration missions. This was the fifth flight of Firefly’s Alpha rocket, capable of placing about a metric ton of payload into low-Earth orbit.

Anomaly resolution … This was the fifth flight of an Alpha rocket since 2021 and the fourth Alpha flight to achieve orbit. But the last Alpha launch in December failed to place its Lockheed Martin payload into the proper orbit due to a problem during the relighting of its second-stage engine. On this week’s launch, Alpha deployed its NASA-sponsored payloads after a single burn of the second stage, then completed a successful restart of the engine for a plane change maneuver. Engineers traced the problem on the last Alpha flight to a software error. (submitted by Ken the Bin)

Two companies added to DoD’s launch pool. Blue Origin and Stoke Space Technologies — neither of which has yet reached orbit — have been approved by the US Space Force to compete for future launches of small payloads, Breaking Defense reports. Blue Origin and Stoke Space join a roster of launch companies eligible to compete for launch task orders the Space Force puts up for bid through the Orbital Services Program-4 (OSP-4) contract. Under this contract, Space Systems Command buys launch services for payloads 400 pounds (180 kilograms) or greater, enabling launch from 12 to 24 months of the award of a task order. The OSP-4 contract has an “emphasis on small orbital launch capabilities and launch solutions for Tactically Responsive Space mission needs,” said Lt. Col. Steve Hendershot, chief of Space Systems Command’s small launch and targets division.

An even dozen … Blue Origin aims to launch its orbital-class New Glenn rocket for the first time as soon as late September, while Stoke Space aims to fly its Nova rocket on an orbital test flight next year. The addition of these two companies means there are 12 providers eligible to bid on OSP-4 task orders. The other companies are ABL Space Systems, Aevum, Astra, Firefly Aerospace, Northrop Grumman, Relativity Space, Rocket Lab, SpaceX, United Launch Alliance, and X-Bow.

Italian startup test-fires small rocket. Italian rocket builder Sidereus Space Dynamics has completed the first integrated system test of its EOS rocket, European Spaceflight reports. This test occurred Sunday, culminating in a firing of the rocket’s kerosene/liquid oxygen MR-5 main engine for approximately 11 seconds. The EOS rocket is a novel design, utilizing a single-stage-to-orbit architecture, with the reusable booster returning to Earth from orbit for recovery under a parafoil. The rocket stands less than 14 feet (4.2 meters) tall and will be capable of delivering about 29 pounds (13 kilograms) of payload to low-Earth orbit.

A lean operation … After it completes integrated testing on the ground, the company will conduct the first low-altitude EOS test flights. Founded in 2019, Sidereus has raised 6.6 million euros ($7.1 million) to fund the development of the EOS rocket. While this is a fraction of the funding other European launch startups like Isar Aerospace, MaiaSpace, and Orbex have attracted, the Sidereus’s CEO, Mattia Barbarossa, has previously stated that the company intends to “reshape spaceflight in a fraction of the time and with limited resources.” (submitted by EllPeaTea and Ken the Bin)

NASA (labels by Ars Technica)

United Launch Alliance and Blue Origin are worried about SpaceX’s plans to launch its enormous Starship rocket from Florida.

In documents submitted to the Federal Aviation Administration last month, ULA and Blue Origin raised concerns about the impact of Starship launch operations on their own activities on Florida’s Space Coast. Blue Origin, Jeff Bezos’ space company, urged the federal government to consider capping the number of Starship launches and landings, test-firings, and other operations, and limiting SpaceX’s activities to particular times.

Elon Musk, founder and CEO of SpaceX, called Blue Origin’s filing with the FAA “an obviously disingenuous response. Not cool of them to try (for the third time) to impede SpaceX’s progress by lawfare.” We’ll get to that in a moment.

The FAA and SpaceX are preparing an environmental impact statement for launches and landings of the Super Heavy booster and Starship rocket at Launch Complex 39A at NASA’s Kennedy Space Center (KSC), while the US Space Force is working with SpaceX on a similar environmental review for Starship flights from Space Launch Complex 37 at nearby Cape Canaveral Space Force Station (CCSFS).

These reviews likely won’t be complete until late 2025, at the earliest, and only then will SpaceX be cleared to launch Starship from Florida. SpaceX also must construct launch infrastructure at both sites, which could take a couple of years. This is already underway at Launch Complex 39A.

Big rocket with a big footprint

During the environmental review process, the FAA should weigh how regular flights of the reusable Starship—as many as 120 launches per year, according to TechCrunch—will affect other launch providers operating at Cape Canaveral, ULA and Blue Origin said. SpaceX’s final proposed launch cadence from each site will be part of draft environmental assessments released for public comment as soon as the end of this year.

SpaceX plans to launch Starlink satellites, customer payloads, and missions to support NASA’s Artemis lunar landings from the launch pads in Florida. Getting a launch pad up and running in Florida is one of several schedule hurdles facing SpaceX’s program to develop a human-rated lunar lander version of Starship, alongside demonstrating orbital refueling.

Starship-Super Heavy launches and landings “are expected to have a greater environmental impact than any other launch system currently operating at KSC or CCSFS,” Blue Origin wrote. In its current configuration, Starship is the most powerful rocket in history, and SpaceX is developing a larger version standing 492 feet (150 meters) tall with nearly 15 million pounds (6,700 metric tons) of propellant. This larger variant is the one that will fly from Cape Canaveral.

“It’s a very, very large rocket, and getting bigger,” wrote Tory Bruno, ULA’s CEO, in a post on X. “That quantity of propellant requires an evacuation zone whenever fueled that includes other people’s facilities. A (weekly) launch has injurious sound levels all the way into town. The Cape isn’t meant for a monopoly.”

Enlarge / SpaceX’s Starship rocket launches from Starbase during its second test flight in Boca Chica, Texas, on November 18, 2023.

At SpaceX’s privately owned Starbase launch site in South Texas, the evacuation zone is set at 1.5 miles (2.5 kilometers) when Starship and Super Heavy are filled with methane and liquid oxygen propellants. During an actual launch, the checkpoint is farther back at more than 3 miles (5 kilometers) from the pad.

“The total launch capacity of the Cape will go down if other providers are forced to evacuate their facilities whenever a vehicle is fueled,” Bruno wrote.

We don’t yet know the radius of the keep-out zones for Starship operations in Florida, but Blue Origin wrote that the impact of Starship activities in Florida “may be even greater than at Starbase,” presumably due to the larger rocket SpaceX plans to launch from Cape Canaveral. If this is the case, neighboring launch pads would need to be evacuated during Starship operations.

Purely based on the geography of Cape Canaveral, ULA seems to have the bigger worry. Its launch pad for the Vulcan and Atlas V rocket is located less than 2.2 miles (3.5 kilometers) from Launch Complex 39A (LC-39A). SpaceX’s proposal for up to 44 launches from LC-39A “will result in significant airspace and ground closures, result in acoustic impacts felt at nearby operations, and potentially produce debris, particulates, and property damage,” ULA said.

ULA said these hazards could prevent it from fulfilling its contracts to launch critical national security satellites for the US military.

“As the largest rocket in existence, an accident would inflict serious or even catastrophic damage, while normal launch operations would have a cumulative impact on structures, launch vehicle hardware, and other critical launch support equipment,” ULA said.

SpaceX is about to launch Starship again—the FAA will be more forgiving this time

SpaceX

The Federal Aviation Administration approved the commercial launch license for the fourth test flight of SpaceX’s Starship rocket Tuesday, with liftoff from South Texas targeted for just after sunrise Thursday.

“The FAA has approved a license authorization for SpaceX Starship Flight 4,” the agency said in a statement. “SpaceX met all safety and other licensing requirements for this test flight.”

Shortly after the FAA announced the launch license, SpaceX confirmed plans to launch the fourth test flight of the world’s largest rocket at 7: 00 am CDT (12: 00 UTC) Thursday. The launch window runs for two hours.

This flight follows three prior demonstration missions, each progressively more successful, of SpaceX’s privately developed mega-rocket. The last time Starship flew—on March 14—it completed an eight-and-a-half minute climb into space, but the ship was unable to maneuver itself as it coasted nearly 150 miles (250 km) above Earth. This controllability problem caused the rocket to break apart during reentry.

On Thursday’s flight, SpaceX officials will expect the ascent portion of the test flight to be similarly successful to the launch in March. The objectives this time will be to demonstrate Starship’s ability to survive the most extreme heating of reentry, when temperatures peak at 2,600° Fahrenheit (1,430° Celsius) as the vehicle plunges into the atmosphere at more than 20 times the speed of sound.

SpaceX officials also hope to see the Super Heavy booster guide itself toward a soft splashdown in the Gulf of Mexico just offshore from the company’s launch site, known as Starbase, in Cameron County, Texas.

“The fourth flight test turns our focus from achieving orbit to demonstrating the ability to return and reuse Starship and Super Heavy,” SpaceX wrote in an overview of the mission.

Last month, SpaceX completed a “wet dress rehearsal” at Starbase, where the launch team fully loaded the rocket with cryogenic methane and liquid oxygen propellants. Before the practice countdown, SpaceX test-fired the booster and ship at the launch site. More recently, technicians installed components of the rocket’s self-destruct system, which would activate to blow up the rocket if it flies off course.

Then, on Tuesday, SpaceX lowered the Starship upper stage from the top of the Super Heavy booster, presumably to perform final touch-ups to the ship’s heat shield, composed of 18,000 hexagonal ceramic tiles to protect its stainless-steel structure during reentry. Ground teams were expected to raise the ship, or upper stage, back on top of the booster sometime Wednesday, returning the rocket to its full height of 397 feet (121 meters) ahead of Thursday morning’s launch window.

The tick-tock of Starship’s fourth flight

If all goes according to plan, SpaceX’s launch team will start loading 10 million pounds of super-cold propellants into the rocket around 49 minutes before liftoff Thursday. The methane and liquid oxygen will first flow into the smaller tanks on the ship, then into the larger tanks on the booster.

The rocket should be fully loaded about three minutes prior to launch, and, following a sequence of automated checks, the computer controlling the countdown will give the command to light the booster’s 33 Raptor engines. Three seconds later, the rocket will begin its vertical climb off the launch mount, with its engines capable of producing more than 16 million pounds of thrust at full power.

Heading east from the Texas Gulf Coast, the rocket will exceed the speed of sound in about a minute, then begin shutting down its 33 main engines around 2 minutes and 41 seconds after liftoff. Then, just as the Super Heavy booster jettisons to begin a descent back to Earth, Starship’s six Raptor engines will ignite to continue pushing the upper portion of the rocket into space. Starship’s engines are expected to burn until T+ 8 minutes, 23 seconds, accelerating the rocket to near-orbital velocity with enough energy to fly an arcing trajectory halfway around the world to the Indian Ocean.

All of this will be similar to the events of the last Starship launch in March. What differs in the flight plan this time involves the attempts to steer the booster and ship back to Earth. This is important to lay the groundwork for future flights, when SpaceX wants to bring the Super Heavy booster—the size of the fuselage of a Boeing 747 jumbo jet—to a landing back at its launch pad. Eventually, SpaceX also intends to recover reusable Starships back at Starbase or other spaceports.

This infographic released by SpaceX shows the flight profile for SpaceX's fourth Starship launch.

SpaceX

Based on the results of the March test flight, SpaceX still has a lot to prove in these areas. On that flight, the engines on the Super Heavy booster could not complete all the burns required to guide the rocket toward the splashdown zone in the Gulf of Mexico. The booster lost control as it plummeted toward the ocean.

Engineers traced the failure to blockage in a filter where liquid oxygen flows into the Raptor engines. Notably, a similar problem occurred on the second Starship test flight last November. The Super Heavy booster awaiting launch Thursday has additional hardware to improve propellant filtration capabilities, according to SpaceX. The company also implemented “operational changes” on the booster for the upcoming test flight, including to jettison the Super Heavy’s staging ring, which sits between the booster and ship during launch, to reduce the rocket’s mass during descent.

SpaceX has a lot of experience bringing back its fleet of Falcon 9 boosters. The company now boasts a streak of more than 240 successful rocket landings in a row, so it’s reasonable to expect SpaceX will overcome the challenge of recovering the larger Super Heavy booster.

Welcome to Edition 6.46 of the Rocket Report!

All of this is happening as SpaceX keeps up its cadence of flying multiple Starlink missions per week.

Another North Korean launch failure. North Korea’s latest attempt to launch a rocket with a military reconnaissance satellite ended in failure due to the midair explosion of the rocket during the first-stage flight this week, South Korea’s Yonhap News Agency reports. Video captured by the Japanese news organization NHK appears to show the North Korean rocket disappearing in a fireball shortly after liftoff Monday night from a launch pad on the country’s northwest coast. North Korean officials acknowledged the launch failure and said the rocket was carrying a small reconnaissance satellite named Malligyong-1-1.

Russia’s role? … Experts initially thought the pending North Korean launch, which was known ahead of time from international airspace warning notices, would use the same Chŏllima 1 rocket used on three flights last year. But North Korean statements following the launch Monday indicated the rocket used a new propulsion system burning a petroleum-based fuel, presumably kerosene, with liquid oxygen as the oxidizer. The Chŏllima 1 rocket design used a toxic mixture of hypergolic hydrazine and nitrogen tetroxide as propellants. If North Korea’s statement is true, this would be a notable leap in the country’s rocket technology and begs the question of whether Russia played a significant role in the launch. Last year, Russian President Vladimir Putin pledged more Russian support for North Korea’s rocket program in a meeting with North Korean leader Kim Jong Un. (submitted by Ken the Bin and Jay500001)

Rocket Lab deploys small NASA climate satellite. Rocket Lab is in the midst of back-to-back launches for NASA, carrying identical climate research satellites into different orbits to study heat loss to space in Earth’s polar regions. The Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) satellites are each about the size of a shoebox, and NASA says data from PREFIRE will improve computer models that researchers use to predict how Earth’s ice, seas, and weather will change in a warming world. “The difference between the amount of heat Earth absorbs at the tropics and that radiated out from the Arctic and Antarctic is a key influence on the planet’s temperature, helping to drive dynamic systems of climate and weather,” NASA said in a statement.

Twice in a week… NASA selected Rocket Lab’s Electron launch vehicle to deliver the two PREFIRE satellites into orbit on two dedicated rides rather than launching at a lower cost on a rideshare mission. This is because scientists want the satellites flying at the proper alignment to ensure they fly over the poles several hours apart, providing the data needed to measure how the rate at which heat radiates from the polar regions changes over time. The first PREFIRE launch occurred on May 25, and the next one is slated for May 31. Both launches will take off from Rocket Lab’s base in New Zealand. (submitted by Ken the Bin)

A rocket launch comes to Rizhao. China has diversified its launch sector over the last decade to include new families of small satellite launchers and new spaceports. One of these relatively new small rockets, the solid-fueled Ceres 1, took off Wednesday from a floating launch pad positioned about 2 miles (3 km) off the coast of Rizhao, a city of roughly 3 million people in China’s Shandong province. The Ceres 1 rocket, developed by a quasi-commercial company called Galactic Energy, has previously flown from land-based launch pads and a sea-borne platform, but this mission originated from a location remarkably close to shore, with the skyline of a major metropolitan area as a backdrop.

Range safety … There’s no obvious orbital mechanics reason to position the rocket’s floating launch platform so near a major Chinese city, other than perhaps to gain a logistical advantage by launching close to port. The Ceres 1 rocket has a fairly good reliability record—11 successes in 12 flights—but for safety reasons, there’s no Western spaceport that would allow members of the public (not to mention a few million) to get so close to a rocket launch. For decades, Chinese rockets have routinely dropped rocket boosters containing toxic propellant on farms and villages downrange from the country’s inland spaceports.

“I lied” —

More than 60 years after he was denied an opportunity to become America’s first Black astronaut, Ed Dwight finally traveled into space Sunday with five other passengers on a 10-minute flight inside a Blue Origin capsule.

Dwight, a retired Air Force captain and test pilot, had a chance to become the first African American astronaut. He was one of 26 pilots the Air Force recommended to NASA for the third class of astronauts in 1963, but the agency didn’t select him. It took another 20 years for America’s first Black astronaut, Guion Bluford, to fly in space in 1983.

“Everything they did, I did, and I did it well,” Dwight said in a video released by Blue Origin. “If politics had changed, I would have gone to space in some kind of capacity.”

At the age of 90, Dwight finally entered the record books Sunday, becoming the oldest person to reach space, displacing the previous record-holder, actor William Shatner, who flew on a similar Blue Origin launch to the edge of space in 2021.

“I thought I didn’t need it in my life,” Dwight said after Sunday’s fight. “But I lied!”

Since retiring from the Air Force, Dwight became an accomplished sculptor. His works, which focus on Black history, are installed at memorials and monuments across the country.

“The transitions, the separations and stuff were a little bit more dynamic than I thought,” Dwight said in remarks after Sunday’s flight. “But that’s how it’s supposed to be. It makes your mind wonder, ‘Is something wrong?’ But no, it was absolutely terrific and the view … absolutely fantastic. This was a life-changing experience. Everybody needs to do this.”

Dwight and his five co-passengers lifted off from Blue Origin’s remote launch site in West Texas at 9: 35 am CDT (14: 35 UTC). Strapped into reclining seats inside a pressurized capsule, the passengers rode Blue Origin’s New Shepard rocket into the uppermost layers of the atmosphere. After burning its main engine more than two minutes, the rocket released the crew capsule and continued coasting upward to an apogee, or high point, of nearly 66 miles (107 kilometers), just above the internationally recognized boundary of space.

This was the seventh time Blue Origin, the space company owned by billionaire Jeff Bezos, has flown people to suborbital space, and the 25th flight overall of the company’s fleet of New Shepard rockets. It was the first time Blue Origin has launched people in nearly two years, resuming suborbital service after a rocket failure on an uncrewed research flight in September 2022. In December, Blue Origin launched another uncrewed suborbital research mission to set the stage for the resumption of human missions Sunday.

Joining Dwight on Blue Origin’s capsule were investor Mason Angel, French businessman Sylvain Chiron, software engineer Kenneth Hess, adventurer Carol Schaller, and Gopi Thotakura, an Indian pilot and entrepreneur. Dwight’s ticket with Blue Origin was sponsored by Space for Humanity, a nonprofit that seeks to expand access to space for all people, and the other five participants were paying passengers.

After cutoff of the New Shepard rocket engine, the passengers had a few minutes to unfasten their seatbelts and float around the cabin while taking in the view of Earth. They returned to their seats as the capsule descended back into the atmosphere. The reusable New Shepard booster reignited its main engine for a propulsive landing back in Texas, while the crew capsule deployed parachutes to slow for touchdown a few miles away.

Two of three

However, one of the three main parachutes did not fully unfurl as the capsule drifted back to the ground. The capsule is designed to safely land with two chutes, a capability Blue Origin demonstrated on a test flight in 2016.

“It looks like we do have two parachutes that have full inflation, the third is not quite fully inflated,” said Ariane Cornell, a Blue Origin official hosting the company’s live webcast Sunday. “Landing with two parachutes is perfectly OK for this system.”

Family members and Blue Origin personnel greeted the passengers as they exited the capsule. All six appeared to be in good spirits and good health.

Although it had no obvious ill effects on the crew or the spacecraft, Blue Origin engineers will investigate the malfunction to determine what went wrong. The capsule’s three main parachutes were supplied to Blue Origin by Airborne Systems, which manufactures parachutes for every US human-rated spacecraft.

Airborne also provides parachutes for SpaceX’s Dragon spacecraft, Boeing’s Starliner, and NASA’s Orion capsule. Those parachutes have different designs and sizes than the chutes used on Blue Origin’s capsule, but it wasn’t immediately clear if there might be any crossover concerns on other programs stemming from the malfunction on Sunday’s flight.

The Federal Aviation Administration, the regulatory agency that oversees US commercial space missions, said in a statement it did not consider the parachute issue a mishap. This statement suggests the incident will not trigger a mishap investigation that would require FAA oversight.

Before the 2022 launch failure, Blue Origin’s New Shepard program achieved a cadence, on average, of roughly one flight every two months. Virgin Galactic, the space tourism company founded by Richard Branson, ramped up the flight rate of its suborbital SpaceShipTwo spaceplane over the last year as Blue Origin’s rocket remained grounded.

But Virgin Galactic is about to halt operations of its own spaceship following one more flight with passengers next month. The company says it decided to suspend flights of the VSS Unity rocket plane to focus its resources on developing a fleet of larger air-launched spaceships that are easier to reuse.

This means Blue Origin, assuming it can regain or build on the cadence it demonstrated in 2021 and 2022, will be the only company serving the suborbital space tourism and research market for at least the next couple of years.

We take a stab at decoding SpaceX’s ever-changing plans for Starship in Florida

Enlarge / SpaceX’s Starship tower (left) at Launch Complex 39A dwarfs the launch pad for the Falcon 9 rocket (right).

There are a couple of ways to read the announcement from the Federal Aviation Administration that it’s kicking off a new environmental review of SpaceX’s plan to launch the most powerful rocket in the world from Florida.

The FAA said on May 10 that it plans to develop an Environmental Impact Statement (EIS) for SpaceX’s proposal to launch Starships from NASA’s Kennedy Space Center in Florida. The FAA ordered this review after SpaceX updated the regulatory agency on the projected Starship launch rate and the design of the ground infrastructure needed at Launch Complex 39A (LC-39A), the historic launch pad once used for Apollo and Space Shuttle missions.

Dual environmental reviews

At the same time, the US Space Force is overseeing a similar EIS for SpaceX’s proposal to take over a launch pad at Cape Canaveral Space Force Station, a few miles south of LC-39A. This launch pad, designated Space Launch Complex 37 (SLC-37), is available for use after United Launch Alliance’s last Delta rocket lifted off there in April.

On the one hand, these environmental reviews often take a while and could cloud Elon Musk’s goal of having Starship launch sites in Florida ready for service by the end of 2025. “A couple of years would not be a surprise,” said George Nield, an aerospace industry consultant and former head of the FAA’s Office of Commercial Space Transportation.

Another way to look at the recent FAA and Space Force announcements of pending environmental reviews is that SpaceX finally appears to be cementing its plans to launch Starship from Florida. These plans have changed quite a bit in the last five years.

The environmental reviews will culminate in a decision on whether to approve SpaceX’s proposals for Starship launches at LC-39A and SLC-37. The FAA will then go through a separate licensing process, similar to the framework used to license the first three Starship test launches from South Texas.

NASA has contracts with SpaceX worth more than $4 billion to develop a human-rated version of Starship to land astronauts on the Moon on the first two Artemis lunar landing flights later this decade. To do that, SpaceX must stage a fuel depot in low-Earth orbit to refuel the Starship lunar lander before it heads for the Moon. It will take a series of Starship tanker flights—perhaps 10 to 15—to fill the depot with cryogenic propellants.

Launching that many Starships over the course of a month or two will require SpaceX to alternate between at least two launch pads. NASA and SpaceX officials say the best way to do this is by launching Starships from one pad in Texas and another in Florida.

Earlier this week, Ars spoke with Lisa Watson-Morgan, who manages NASA’s human-rated lunar lander program. She was at Kennedy Space Center this week for briefings on the Starship lander and a competing lander from Blue Origin. One of the topics, she said, was the FAA’s new environmental review before Starship can launch from LC-39A.

“I would say we’re doing all we can to pull the schedule to where it needs to be, and we are working with SpaceX to make sure that their timeline, the EIS timeline, and NASA’s all work in parallel as much as we can to achieve our objectives,” she said. “When you’re writing it down on paper just as it is, it looks like there could be some tight areas, but I would say we’re collectively working through it.”

Officially, SpaceX plans to perform a dress rehearsal for the Starship lunar landing in late 2025. This will be a full demonstration, with refueling missions, an uncrewed landing of Starship on the lunar surface, then a takeoff from the Moon, before NASA commits to putting people on Starship on the Artemis III mission, currently slated for September 2026.

So you can see that schedules are already tight for the Starship lunar landing demonstration if SpaceX activates launch pads in Florida late next year.

Welcome to Edition 6.44 of the Rocket Report! Kathy Lueders, general manager of SpaceX’s Starbase launch facility, says the company expects to receive an FAA launch license for the next Starship test flight shortly after Memorial Day. It looks like this rocket could fly in late May or early June, about two-and-a-half months after the previous Starship test flight. This is an improvement over the previous intervals of seven months and four months between Starship flights.

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.

Blue Origin launch on tap this weekend. Blue Origin plans to launch its first human spaceflight mission in nearly two years on Sunday. This flight will launch six passengers on a flight to suborbital space more than 60 miles (100 km) over West Texas. Blue Origin, Jeff Bezos’s space company, has not flown people to space since a New Shepard rocket failure on an uncrewed research flight in September 2022. The company successfully launched New Shepard on another uncrewed suborbital mission in December.

Historic flight … This will be the 25th flight of Blue Origin’s New Shepard rocket, and the seventh human spaceflight mission on New Shepard. Before Blue Origin’s rocket failure in 2022, the company was reaching a flight cadence of about one launch every two months, on average. The flight rate has diminished since then. Sunday’s flight is important not only because it marks the resumption of launches for Blue Origin’s suborbital human spaceflight business, but also because its six-person crew includes an aviation pioneer. Ed Dwight, 90, almost became the first Black astronaut in 1963. Dwight, a retired Air Force captain, piloted military fighter jets and graduated test pilot school, following a familiar career track as many of the early astronauts. He was on a short list of astronaut candidates the Air Force provided NASA, but the space agency didn’t include him. Dwight will become the oldest person to ever fly in space.

Spaceport Camden is officially no more. With the stroke of a pen, Georgia Governor Brian Kemp signed a bill that dissolved the Camden County Spaceport Authority, Action News Jax reported. This news follows a referendum in March 2022 where more than 70 percent of voters rejected a plan to buy land for the spaceport on the Georgia coastline between Savannah and Jacksonville, Florida. County officials still tried to move forward with the spaceport initiative after the failed referendum, but Georgia’s Supreme Court ruled in February that the county had to abide by the voters’ wishes.

$12 million for what?… The government of Camden County, with a population of about 55,000 people spent $12 million on the Spaceport Camden concept over the course of a decade. The goal of the spaceport authority was to lure small launch companies to the region, but no major launches ever took place from Camden County. State Rep. Steven Sainz, who sponsored the bill eliminating the spaceport authority, said in a statement that the legislation “reflects the community’s choice and opens a path for future collaborations in economic initiatives that are more aligned with local needs.” (submitted by zapman987)

Polaris Spaceplanes moves on to bigger things. German startup Polaris Spaceplanes says it is progressing with construction of its MIRA II and MIRA III spaceplane prototypes after MIRA, a subscale test vehicle, was damaged earlier this year, European Spaceflight reports. The MIRA demonstration vehicle crash-landed on a test flight in February. The incident occurred on takeoff at an airfield in Germany before the vehicle could ignite its linear aerospace engine in flight. The remote-controlled MIRA prototype measured about 4.25 meters long. Polaris announced on April 30 that will not repair MIRA and will instead move forward with the construction of a pair of larger vehicles.

Nearly 16 months without a launch … The MIRA II and MIRA III vehicles will be 5 meters long and will be powered by Polaris’s AS-1 aerospike engines, along with jet engines to power the craft before and after in-flight tests of the rocket engine. Aerospike engines are rocket engines that are designed to operate efficiently at all altitudes. The MIRA test vehicles are precursors to AURORA, a multipurpose spaceplane and hypersonic transporter Polaris says will be capable of delivering up to 1,000 kilograms of payload to low-Earth orbit.

Two giants in the satellite telecom industry join forces to counter Starlink

M&A —

SES is buying Intelsat, the world’s first commercial satellite operator, for $3.1 billion.

Facing competition from Starlink and other emerging satellite broadband networks, the two companies that own most of the traditional commercial communications spacecraft in geostationary orbit announced plans to join forces Tuesday.

SES, based in Luxembourg, will buy Intelsat for $3.1 billion. The acquisition will create a combined company boasting a fleet of some 100 multi-ton satellites in geostationary orbit, a ring of spacecraft located more than 22,000 miles (nearly 36,000 kilometers) over the equator. This will be more than twice the size of the fleet of the next-largest commercial geostationary satellite operator.

The problem is that demand is waning for communication services through large geostationary (GEO) satellites. There are some large entrenched customers, like video media companies and the military, that will continue to buy telecom capacity on geostationary satellites. But there’s a growing demand among consumers, and some segments of the corporate and government markets, for the types of services offered by constellations of smaller satellites flying closer to Earth.

The biggest of these constellations, by far, is SpaceX’s Starlink network, with more than 5,800 active satellites in its low-Earth orbit fleet a few hundred miles above Earth. Each of the Starlink satellites is smaller than a conventional geostationary platform, but linked together with laser communication terminals, thousands of these spacecraft pack enough punch to eclipse the capacity of internet networks anchored by geostationary satellites. Starlink now has more than 2.6 million subscribers, according to SpaceX.

Satellites in low-Earth orbit (LEO) offer some advantages over geostationary satellites. Because they are closer to users on the ground, low-Earth orbit satellites provide signals with lower latency. The satellites for these constellations can be mass-produced at relatively low cost, compared to a single geostationary satellite, which often costs $250 million or more to build and launch.

“In a fast-moving and competitive satellite communication industry, this transaction expands our multi-orbit space network, spectrum portfolio, ground infrastructure around the world, go-to-market capabilities, managed service solutions, and financial profile,” said Adel Al-Saleh, CEO of SES, in a statement announcing the acquisition of Intelsat.

A trend of consolidation

Some of the largest legacy operators in geostationary orbit have made moves over the last decade to respond to the new competition.

The only operational low-Earth orbit internet constellation besides Starlink was launched by OneWeb, which primarily sells capacity to existing internet providers, who then distribute services to individual consumers. This is in contrast to SpaceX’s approach with Starlink providing services direct to homes and businesses.

Eutelsat, the third-largest operator of geostationary satellites, merged with OneWeb last year, creating a company with a blended offering of GEO and LEO services. Viasat, a pioneer in satellite internet services using dedicated spacecraft in geostationary orbit, last year purchased Inmarsat, which specialized in providing connectivity to airplanes and ships.

SES’s acquisition of Intelsat stands apart due to the size of their satellite fleets. Founded in 1985, SES currently operates 43 geostationary satellites, plus 26 broadband spacecraft in medium-Earth orbit (MEO) a few thousand miles above Earth. These MEO satellites operate in a kind of middle ground between LEO and GEO satellites, offering lower-latency than geostationary networks, while still flying high enough to not require hundreds or thousands of spacecraft to blanket the globe.

Intelsat has 57 geostationary satellites, primarily for television and video relay services. Al-Saleh said the combined company will offer coverage over 99 percent of the world, and provide services through a range of communication bands. For now, LEO broadband satellites in the Starlink and OneWeb networks beam signals to user terminals in Ku-band.

Al-Saleh said the combined networks of SES and Intelsat will span Ka-band, Ku-band, X-band, C-band, UHF, and secure bands tailored for military use. “That gives us a unique position in the market place to be able to deliver to our clients,” he said.

SES and Intelsat have 13 new satellites on order, including six GEO spacecraft and seven broadband MEO satellites. Intelsat also brings to the table access to OneWeb’s LEO constellation. Earlier this year, Intelsat announced it reserved $250 million of capacity on OneWeb’s network over the next six years, with an option to purchase double that amount.

This illustration shows the relative locations of satellites in geostationary orbit, medium-Earth orbit, and low-Earth orbit.

“We will create a stronger expanded network capabilities that are multi-orbit,” Al-Saleh said in an earnings call Tuesday. “We are not just a GEO player. We are an all-orbit player.”

Internet signals coming from a GEO satellite, like a Viasat spacecraft, typically have a latency of about 600 milliseconds. Al-Saleh said SES’s O3b network in medium-Earth orbit provides signals with a latency of about 120 milliseconds. According to SpaceX, Starlink latency ranges between 25 and 60 milliseconds.

A satellite pioneer

Intelsat has a storied history. Founded in 1964 as an intergovernmental organization, Intelsat operated the first commercial communications satellite in geostationary orbit. It became a private company in 2001, then went public in 2013 before filing for bankruptcy in 2020. Intelsat emerged from bankruptcy proceedings as a private company in 2022.

“Over the past two years, the Intelsat team has executed a remarkable strategic reset,” said David Wajsgras, CEO of Intelsat, in a statement. “We have reversed a 10-year negative trend to return to growth, established a new and game-changing technology roadmap, and focused on productivity and execution to deliver competitive capabilities.”

SES and Intelsat expect the acquisition to close in the second half of 2025, pending regulatory approvals. The boards of both companies unanimously approved the transaction.

Both companies maintain hundreds of millions of dollars of business with the US government each year, and the military’s appetite for commercial satellite communications is going up. “I think many of the satellite players are seeing the benefit of that, not just us,” Al-Saleh said. “You can look at our competitors. You can look at Starlink. You can look at others. We’re all seeing an uptick in demand.”

Al-Saleh said he doesn’t foresee any roadblocks from the Pentagon or any government regulators before closing the transaction next year.

SES and Intelsat revealed last year there were in talks to combine. According to Al-Saleh, SES looked at multiple opportunities for mergers or acquisitions to make use of a multibillion-dollar windfall from the Federal Communications Commission tied to the auction of C-band satellite spectrum for cellular networks.

“It was clear to us that this particular transaction, if we’re able to successfully close it with the right type of value, is the most compelling proposition we had on the table,” he said.

SpaceX’s most-flown reusable rocket will go for its 20th launch tonight

For the first time, SpaceX will launch one of its reusable Falcon 9 boosters for a 20th time Friday night on a flight to deliver 23 more Starlink Internet satellites to orbit.

This milestone mission is scheduled to lift off at 9: 22 pm EDT Friday (01: 22 UTC Saturday) from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station, Florida. Forecasters from the US Space Force predict “excellent” weather for the primetime launch.

Falcon 9 will blaze a familiar trail into space, following the same profile as dozens of past Starlink missions.

The rocket’s first-stage booster will shut off its nine kerosene-fueled Merlin engines about two-and-a-half minutes into the flight, reaching a top speed of more than 5,000 mph (8,000 km per hour). The first stage will detach from the Falcon 9’s upper stage, which will continue firing into orbit. The 15-story-tall Falcon 9 booster, meanwhile, will follow an arcing trajectory before braking for a vertical landing on a drone ship floating in the Atlantic Ocean near the Bahamas.

The 23 flat-packed Starlink spacecraft will deploy from the upper stage a little more than an hour after liftoff, bringing the total number of Starlinks in low-Earth orbit to more than 5,800 spacecraft.

A hunger for launch

Pretty much every day, SpaceX is either launching a rocket or rolling one out of the hangar to the launch pad. At this pace, SpaceX is redefining what is routine in the space industry, but the rapid-fire launch rate also means the company is continually breaking records, mostly its own.

Friday night’s launch will break another one of those records. This first-stage booster, designated by the tail number B1062, has flown 19 times since its first flight in November 2020. The booster will now be the first in SpaceX’s inventory to go for a 20th flight, breaking a tie with three other rockets as the company’s fleet leader.

When SpaceX debuted the latest version of its Falcon 9 rocket, the Falcon 9 Block 5, officials said the reusable first stage could fly 10 times with minimal refurbishment and perhaps additional flights with a more extensive overhaul. Now, SpaceX is certifying Falcon 9 boosters for 40 flights.

This particular rocket has not undergone any extended maintenance or long-term grounding. It has flown an average of once every two months since debuting three-and-a-half years ago. So the 20-flight milestone SpaceX will achieve Friday night means this rocket has doubled its original design life and, at the same time, has reached the halfway point of its extended service life.

In its career, this booster has launched eight people and 530 spacecraft, mostly Starlinks. The rocket’s first two flights launched GPS navigation satellites for the US military, then it launched two commercial human spaceflight missions with Dragon crew capsules. These were the all-private Inspiration4 mission and Axiom Mission 1, the first fully commercial crew flight to the International Space Station.

Remarkably, this will be the sixth Falcon 9 launch in less than eight days, more flights than SpaceX’s main US rival, United Launch Alliance, has launched in 17 months.

It will be the 38th Falcon 9 launch of the year and the 111th flight of a Falcon 9 or Falcon Heavy rocket—the 114th launch by SpaceX overall—in the last 365 days. More than a third of SpaceX’s Falcon 9 or Falcon Heavy missions, a number that will stand at 332 after Friday night’s flight, have launched in the past year.

This month, for the first time, SpaceX demonstrated it could launch two Falcon 9 rockets in less than five days from the company’s launch pad at Vandenberg Space Force Base, California. SpaceX has also cut the turnaround time between Falcon 9 rockets at Launch Complex 39A at NASA’s Kennedy Space Center. The company’s most-used launch pad, SLC-40, can handle two Falcon 9 flights in less than four days.

It’s not just launch pad turnaround. SpaceX uses its drone ships—two based in Florida and one in California—for most Falcon 9 landings. In order to meet the appetite for Falcon 9 launches, SpaceX is getting rockets back to port and re-deploying drone ships back to sea at a faster rate.

The Space Force is planning what could be the first military exercise in orbit

The US Space Force announced Thursday it is partnering with two companies, Rocket Lab and True Anomaly, for a first-of-its-kind mission to demonstrate how the military might counter “on-orbit aggression.”

On this mission, a spacecraft built and launched by Rocket Lab will chase down another satellite made by True Anomaly, a Colorado-based startup. “The vendors will exercise a realistic threat response scenario in an on-orbit space domain awareness demonstration called Victus Haze,” the Space Force’s Space Systems Command said in a statement.

This threat scenario could involve a satellite performing maneuvers that approach a US spacecraft or a satellite doing something else unusual or unexpected. In such a scenario, the Space Force wants to have the capability to respond, either to deter an adversary from taking action or to defend a US satellite from an attack.

Going up to take a look

“When another nation puts an asset up into space and we don’t quite know what that asset is, we don’t know what its intent is, we don’t know what its capabilities are, we need the ability to go up there and figure out what this thing is,” said Gen. Michael Guetlein, the Space Force’s vice chief of space operations.

This is what the Space Force wants to demonstrate with Victus Haze. For this mission, True Anomaly’s spacecraft will launch first, posing as a satellite from a potential adversary, like China or Russia. Rocket Lab will have a satellite on standby to go up and inspect True Anomaly’s spacecraft and will launch it when the Space Force gives the launch order.

“Pretty sporty,” said Even Rogers, co-founder and CEO of True Anomaly.

Then, if all goes according to plan, the two spacecraft will switch roles, with True Anomaly’s Jackal satellite actively maneuvering around Rocket Lab’s satellite. According to the Space Force, True Anomaly and Rocket Lab will deliver their spacecraft no later than the fall of 2025.

“If a near-peer competitor makes a movement, we need to have it in our quiver to make a counter maneuver, whether that be go up and do a show of force or go up and do space domain awareness or understand the characterization of the environment—what’s going on?” Guetlein said.

Victus Haze is the next in a series of military missions dedicated to validating Tactically Responsive Space (TacRS) capabilities. With these efforts, the Space Force and its commercial partners have shown how they can compress the time it takes to prepare and launch a satellite.

Last year, the Space Force partnered with Firefly Aerospace and Millennium Space Systems on the Victus Nox mission. The Victus Nox satellite was built and tested in less than a year and then readied for launch in less than 60 hours. Firefly successfully launched the spacecraft on its Alpha rocket 27 hours after receiving launch orders from the Space Force, a remarkable achievement in an industry where satellites take years to build and launch campaigns typically last weeks or months.
