SpaceX reveals why the last two Starships failed as another launch draws near

Engineers recreated the diffuser failure on the ground during the investigation, and then redesigned the part to better direct pressurized gas into the main fuel tank. This will also “substantially decrease” strain on the diffuser structure, SpaceX said.

The FAA, charged with ensuring commercial rocket launches don’t endanger public safety, signed off on the investigation and gave the green light for SpaceX to fly Starship again when it is ready.

“SpaceX can now proceed with Starship Flight 10 launch operations under its current license,” the FAA said.

“The upcoming flight will continue to expand the operating envelope on the Super Heavy booster, with multiple landing burn tests planned,” SpaceX said in an update posted to its website Friday. “It will also target similar objectives as previous missions, including Starship’s first payload deployment and multiple reentry experiments geared towards returning the upper stage to the launch site for catch.”

In the aftermath of the test flight in May, SpaceX hoped to fly Starship again by late June or early July. But another accident June 18, this time on the ground, delayed the program another couple of months. The Starship vehicle SpaceX assigned to the next flight, designated Ship 36, exploded on a test stand in Texas as teams filled it with cryogenic propellants for an engine test-firing.

The accident destroyed the ship and damaged the test site, prompting SpaceX to retrofit the sole active Starship launch pad to support testing of the next ship in line—Ship 37. Those tests included a brief firing of all six of the ship’s Raptor engines August 1.

After Ship 37’s final spin prime test Wednesday, workers transported the rocket back to a hangar for evaluation, and crews immediately got to work transitioning the launch pad back to its normal configuration to host a full Super Heavy/Starship stack.

SpaceX said the explosion on the test stand in June was likely caused by damage to a high-pressure nitrogen storage tank inside Starship’s payload bay section. This tank, called a composite overwrapped pressure vessel, or COPV, violently ruptured and led to the ship’s fiery demise. SpaceX said COPVs on upcoming flights will operate at lower pressures, and managers ordered additional inspections on COPVs to look for damage, more proof testing, more stringent acceptance criteria, and a hardware change to address the problem.

NASA’s acting chief calls for the end of Earth science at the space agency

Sean Duffy, the acting administrator of NASA for a little more than a month, has vowed to make the United States great in space.

With a background as a US Congressman, reality TV star, and television commentator, Duffy did not come to the position with a deep well of knowledge about spaceflight. He also already had a lot on his plate, serving as the secretary of transportation, a Cabinet-level position that oversees 55,000 employees across 13 agencies.

Nevertheless, Duffy is putting his imprint on the space agency, seeking to emphasize the agency’s human exploration plans, including the development of a lunar base, and ending NASA’s efforts to study planet Earth and its changing climate.

Duffy has not spoken much with reporters who cover the space industry, but he has been a frequent presence on Fox News networks, where he previously worked as a host. On Thursday, he made an 11-minute appearance on “Mornings with Maria,” a FOX Business show hosted by Maria Bartiromo to discuss NASA.

NASA should explore, he says

During this appearance, Duffy talked up NASA’s plans to establish a permanent presence on the Moon and his push to develop a nuclear reactor that could provide power there. He also emphasized his desire to end NASA’s focus on studying the Earth and understanding how the planet’s surface and atmosphere are changing. This shift has been a priority of the Trump Administration at other federal agencies.

“All the climate science, and all of the other priorities that the last administration had at NASA, we’re going to move aside, and all of the science that we do is going to be directed towards exploration, which is the mission of NASA,” Duffy said during the appearance. “That’s why we have NASA, to explore, not to do all of these Earth sciences.”

Portugal green-lights Azores spaceport. The Portuguese government has granted the Atlantic Spaceport Consortium a license to build and operate a rocket launch facility on the island of Santa Maria in the Azores, European Spaceflight reports. The Atlantic Spaceport Consortium (ASC) was founded in 2019 with the goal of developing a commercial spaceport on Santa Maria, 1,500 kilometers off the Portuguese mainland. In September 2024, the company showcased the island’s suitability as a launch site by launching two small solid-fuel amateur-class rockets that it developed in-house.

What’s on deck? … The spaceport license granted by Portugal’s regulatory authorities does not cover individual launches themselves. Those must be approved in a separate licensing process. It’s likely that the launch site on Santa Maria Island will initially host suborbital launches, including flights by the Polish rocket company SpaceForest. The European Space Agency has also selected Santa Maria as the landing site for the first flight of the Space Rider lifting body vehicle after it launches into orbit, perhaps in 2027.

Why is Jeff Bezos buying launches from Elon Musk? Early Monday morning, a Falcon 9 rocket lifted off from its original launch site in Florida. Remarkably, it was SpaceX’s 100th launch of the year. Perhaps even more notable was the rocket’s payload: two-dozen Project Kuiper satellites, which were dispensed into low-Earth orbit on target, Ars reports. This was SpaceX’s second launch of satellites for Amazon, which is developing a constellation to deliver low-latency broadband Internet around the world. SpaceX, then, just launched a direct competitor to its Starlink network into orbit. And it was for the founder of Amazon, Jeff Bezos, who owns a rocket company of his own in Blue Origin.

Several answers … So how did it come to this—Bezos and Elon Musk, competitors in so many ways, working together in space? There are several answers. Most obviously, launching payloads for customers is one of SpaceX’s two core business areas, alongside Starlink. SpaceX sells launch services to all comers and typically offers the lowest price per kilogram to orbit. There’s immediate revenue to be made if a company with deep pockets like Amazon is willing to pay SpaceX. Second, the other options to get Kuiper satellites into orbit just aren’t available at the volume Amazon needs. Amazon has reserved the lion’s share of its Kuiper launches with SpaceX’s competitors: United Launch Alliance, Arianespace, and Jeff Bezos’ own space company Blue Origin. Lastly, SpaceX could gain some leverage by providing launch services to Amazon. In return for a launch, SpaceX has asked other companies with telecom satellites, such as OneWeb and Kepler Communications, to share spectrum rights to enable Starlink to expand into new markets.

Trump orders cull of regulations governing commercial rocket launches

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

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

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

Deregulation time

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

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

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

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

After first operational launch, here’s the next big test for ULA’s Vulcan rocket

United Launch Alliance delivered multiple US military satellites into a high-altitude orbit after a prime-time launch Tuesday night, marking an important transition from development to operations for the company’s new Vulcan rocket.

This mission, officially designated USSF-106 by the US Space Force, was the first flight of ULA’s Vulcan rocket to carry national security payloads. Two test flights of the Vulcan rocket last year gave military officials enough confidence to certify it for launching the Pentagon’s medium-to-large space missions.

United Launch Alliance’s third 202-foot-tall (61.6-meter) Vulcan rocket lifted off from Cape Canaveral Space Force Station, Florida, at 8:56 pm EDT Tuesday (00:56 UTC Wednesday). Two methane-burning BE-4 main engines, supplied by Jeff Bezos’ space company Blue Origin, and four solid-fueled boosters from Northrop Grumman powered the rocket off the launch pad with nearly 3 million pounds of thrust.

The rocket steered east from Florida’s Space Coast and climbed through the atmosphere, shedding its four strap-on boosters, core stage, and payload fairing to fall into the Atlantic Ocean. Vulcan’s Centaur upper stage ignited its RL10 engines several times to maneuver into a near-circular geosynchronous orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.

These maneuvers took approximately seven hours to complete before the Centaur upper stage released its payloads to begin their missions. One of the satellites is an experimental platform to test next-generation technologies that may improve GPS navigation. There was at least one additional satellite—and perhaps more—aboard the rocket that the Space Force declined to discuss publicly.

Taking a bite of the apple

ULA and Space Force officials declared success early Wednesday, celebrating the Vulcan rocket’s entry into service as ULA begins the challenging task of working through a firm backlog of more than 70 Vulcan launches on contract. Nearly all of the Vulcan launches have been booked by the Space Force’s National Security Space Launch (NSSL) program and by Amazon for its Kuiper satellite broadband network.

Col. Jim Horne, USSF-106 mission director, said in a statement, “It’s an exciting day for us as we launched the first NSSL flight of Vulcan, an outstanding achievement for United Launch Alliance and the nation’s strategic space lift capability. This is an important milestone for the Space Force and all involved.” He added, “After years of development, technical collaboration, and dedication by all involved, including our government mission partners and the entire ULA team, I’m proud to say the first Vulcan NSSL mission delivered its payloads safely into space.”

Space Force officials take secrecy to new heights ahead of key rocket launch

The Vulcan rocket checks off several important boxes for the Space Force. First, it relies entirely on US-made rocket engines. The Atlas V rocket it is replacing uses Russian-built main engines, and given the chilled relations between the two powers, US officials have long desired to stop using Russian engines to power the Pentagon’s satellites into orbit. Second, ULA says the Vulcan rocket will eventually provide a heavy-lift launch capability at a lower cost than the company’s now-retired Delta IV Heavy rocket.

Third, Vulcan provides the Space Force with an alternative to SpaceX’s Falcon 9 and Falcon Heavy, which have been the only rockets in their class available to the military since the last national security mission was launched on an Atlas V rocket one year ago.

Col. Jim Horne, mission director for the USSF-106 launch, said this flight marks a “pretty historic point in our program’s history. We officially end our reliance on Russian-made main engines with this launch, and we continue to maintain our assured access to space with at least two independent rocket service companies that we can leverage to get our capabilities on orbit.”

What’s onboard?

The Space Force has only acknowledged one of the satellites aboard the USSF-106 mission, but there are more payloads cocooned inside the Vulcan rocket’s fairing.

The $250 million mission that officials are willing to talk about is named Navigation Technology Satellite-3, or NTS-3. This experimental spacecraft will test new satellite navigation technologies that may eventually find their way on next-generation GPS satellites. A key focus for engineers who designed and will operate the NTS-3 satellite is to look at ways of overcoming GPS jamming and spoofing, which can degrade satellite navigation signals used by military forces, commercial airliners, and civilian drivers.

“We’re going to be doing, we anticipate, over 100 different experiments,” said Joanna Hinks, senior research aerospace engineer at the Air Force Research Laboratory’s space vehicles directorate, which manages the NTS-3 mission. “Some of the major areas we’re looking at—we have an electronically steerable phased array antenna so that we can deliver higher power to get through interference to the location that it’s needed.”

GPS jamming is especially a problem in and near war zones. Investigators probing the crash of Azerbaijan Airlines Flight 8243 last December determined GPS jamming, likely by Russian military forces attempting to counter a Ukrainian drone strike, interfered with the aircraft’s navigation as it approached its destination in the Russian republic of Chechnya. Azerbaijani government officials blamed a Russian surface-to-air missile for damaging the aircraft, ultimately leading to a crash in nearby Kazakhstan that killed 38 people.

“We have a number of different advanced signals that we’ve designed,” Hinks said. “One of those is the Chimera anti-spoofing signal… to protect civil users from spoofing that’s affecting so many aircraft worldwide today, as well as ships.”

The NTS-3 spacecraft, developed by L3Harris and Northrop Grumman, only takes up a fraction of the Vulcan rocket’s capacity. The satellite weighs less than 3,000 pounds (about 1,250 kilograms), about a quarter of what this version of the Vulcan rocket can deliver to geosynchronous orbit.

Why does Jeff Bezos keep buying launches from Elon Musk?

Early Monday morning, a Falcon 9 rocket lifted off from its original launch site in Florida. Remarkably, it was SpaceX’s 100th launch of the year.

Perhaps even more notable was the rocket’s payload: two-dozen Project Kuiper satellites, which were dispensed into low-Earth orbit on target. This was SpaceX’s second launch of satellites for Amazon, which is developing a constellation to deliver low-latency broadband Internet around the world. SpaceX, then, just launched a direct competitor to its Starlink network into orbit. And it was for the founder of Amazon, Jeff Bezos, who owns a rocket company of his own in Blue Origin.

So how did it come to this—Bezos and Elon Musk, competitors in so many ways, working together in space?

Most obvious answer: SpaceX is a launch business

First and foremost, one of SpaceX’s two core businesses is launching rockets. (The other is its Starlink Internet service). SpaceX sells launch services to all comers and typically offers the lowest price per kilogram to orbit.

By reusing the first stage of the Falcon 9, SpaceX has cracked the code on rapid, reliable launch service. Launch used to be expensive and rare, and it would take years to get manifested onto a rocket. Because the Falcon 9 now flies so frequently, it provides a relatively fast way to get a payload into space.

SpaceX also has proven that it is willing to launch competitors. Between December 2022 and October 2024, SpaceX launched four batches of satellites for OneWeb, another broadband Internet competitor. AST SpaceMobile has purchased multiple launches from SpaceX for its direct-to-device satellites. The Falcon 9 rocket has also launched two Cygnus spacecraft to the International Space Station for Northrop Grumman, a direct competitor to its Cargo Dragon vehicle.

James Lovell, the steady astronaut who brought Apollo 13 home safely, has died

After the Apollo 13 mission, Lovell was named the deputy director of science and applications at NASA’s Manned Spacecraft Center (today, Johnson Space Center) before retiring from both the space agency and Navy on March 1, 1973. Lovell became chief executive officer of Bay-Houston Towing Company in 1975 and then president of Fisk Telephone Systems in 1977.

On January 1, 1981, Lovell joined Centel Corporation as group vice president for business communications systems and, 10 years later, retired as executive vice president and a member of the company’s board of directors.

For 11 years, from 1967 to 1978, Lovell served as a consultant and then chairman of the Physical Fitness Council (today, the President’s Council on Sports, Fitness and Nutrition). He was a member of the board for several organizations, including Federal Signal Corporation in Chicago from 1984 to 2003 and the Astronautics Corporation of America in Milwaukee from 1990 to 1999. He was also chairman of the Astronaut Scholarship Foundation from 1997 to 2005.

Appearances and awards

From 1999 to 2006, Lovell helped run “Lovell’s of Lake Forest,” a restaurant that he and his family opened in Illinois. (The restaurant was then sold to Jay, Lovell’s son, but ultimately closed in 2015.)

In 1994, Lovell worked with Jeffrey Kluger to publish Lost Moon: The Perilous Voyage of Apollo 13, which was later retitled Apollo 13 after serving as the basis for the Ron Howard movie.

In addition to being played by Hanks and having a cameo in Apollo 13, Lovell was also portrayed by Tim Daly in the 1998 HBO miniseries From the Earth to the Moon and Pablo Schreiber in the 2018 Neil Armstrong biopic First Man. Lovell also made a cameo appearance in the 1976 movie The Man Who Fell to Earth.

For his service to the US space program, Lovell was awarded the NASA Distinguished Service and Exceptional Service medals; the Congressional Space Medal of Honor, and Presidential Medal of Freedom. As a member of the Gemini 7, Gemini 12, and Apollo 8 crews, Lovell was bestowed the Harmon International Trophy three times and, with his Apollo 8 crewmates, the Robert J. Collier and Dr. Robert H. Goddard Memorial trophies and was named Time Magazine’s Man of the Year for 1968.

Rocket Report: Firefly lights the markets up; SpaceX starts selling trips to Mars

SpaceX begins offering Starship services to Mars. On Thursday, Gwynne Shotwell, the president and chief operating officer of SpaceX, announced that the company has begun selling rides to Mars. “Get on board! We are going to Mars! SpaceX is now offering Starship services to the red planet,” Shotwell said on X. As part of the announcement, Shotwell said SpaceX has signed a “first of its kind” agreement with the Italian Space Agency.

Racing the Giro d’Mars … The president of the Italian Space Agency, Teodoro Valente, confirmed the news, saying the first Starship flights to Mars (which will, of course, be uncrewed) will carry Italian experiments. “The payloads will gather scientific data during the missions. Italy continues to lead in space exploration!” Valente wrote on X. Left unsaid, of course, is when such flights will take place. It is difficult to see Starship now being ready for a late 2026 window, but early 2029 seems plausible.

ULA will eventually test reuse technology. On Thursday, ahead of the first Vulcan launch of a national security payload next week, United Launch Alliance chief executive Tory Bruno spoke with reporters about various topics, NASA Spaceflight reports. A highlight was ULA’s progress on SMART Reuse, a system aimed at recovering and reusing booster components to reduce costs. Bruno announced that the critical design review for key components is complete, paving the way for building flight-like hardware for certification.

Testing remains a ways away … As development progresses, ULA plans to relocate more components to the aft section of the booster for recovery. “By the time that path is finished, pretty much the only thing being discarded from the booster will be the fuel tanks,” he said. Experimental flights incorporating SMART Reuse could begin as early as 2026, or at least by 2027, but only when aligned with customer needs. One wonders when actual engine recovery and reuse might begin.

Next three launches

August 8: Falcon 9 | Project Kuiper KF-02 | Cape Canaveral Space Force Station, Florida | 13:40 UTC

August 8: Jielong 3 | Undeclared payload | Offshore site, Chinese coastal waters | 16:30 UTC

August 10: Falcon 9 | Starlink 17-4 | Vandenberg Space Force Base, Calif. | 03:43 UTC

Is the Dream Chaser space plane ever going to launch into orbit?

“We wanted to have a fuel system that was green instead of using hypergolics, so we could land it on a runway and we could walk up to the vehicle without being in hazmat suits,” Tom Vice, then Sierra’s chief executive, told Ars in late 2023. “That was hard, I have to say.”

Apparently it still is because, according to Weigel, the process to finish testing of the propulsion system and certify it for an uncrewed spaceflight remains ongoing.

“We still have some of our integrated safety reviews to do, and we’re in the process with updating both of our schedules to try to understand where does that really put us,” she said. “And so Sierra’s working on that, and so I need to wait and just get information back from them to see where they think some of that work lines out.”

First mission may not berth with ISS

According to one source, Sierra is considering a modification to its first mission to shorten the certification period.

The company had planned to fly the vehicle close enough to the space station such that it could be captured and berthed to the orbiting laboratory. One option now under consideration is a mission that would bring Dream Chaser close enough to the station to test key elements of the vehicle in flight but not have it berth.

This would increase confidence in the spacecraft’s propulsion system and provide the data NASA and partner space agencies need to clear the vehicle to approach and berth with the station on its second flight. However, this would require a modification of the company’s contract with NASA, and a final decision has not yet been reached on whether to perform a flyby mission before an actual berthing.

It appears highly unlikely that Dream Chaser will be ready for its debut spaceflight this year for these technical reasons. Another challenge is the availability of its Vulcan launch vehicle. After years of delays, Vulcan is finally due to make its first national security launch as early as this coming Sunday. Assuming this launch is successful, Vulcan has a busy manifest in the coming months for the US Space Force.

Given this, it is uncertain when a Vulcan launch vehicle will become available for Dream Chaser, which was initially designated to fly on Vulcan’s second flight. However, because Dream Chaser was not ready last fall, that rocket flew with a mass simulator on this second launch, back in October 2024.
