The first Long March 12A rocket, roughly the same height and diameter of SpaceX's workhorse Falcon 9, lifted off from the Jiuquan Satellite Launch Center at 9:00 pm EST Monday (02:00 UTC Tuesday).

Less than 10 minutes later, rocket's methane-fueled first stage booster hurtled through the atmosphere at supersonic speed, impacting in a remote region about 200 miles downrange from the Jiuquan spaceport in northwestern China. The booster failed to complete a braking burn to slow down for landing at a prepared location near the edge of the Gobi Desert.

The news of Bruno's sudden resignation was unexpected. His tenure was marked by a decline in ULA's market share as rival SpaceX competed for and won ever-larger US government launch contracts. More recently, Bruno oversaw the successful debut of ULA's Vulcan rocket, followed by struggles to ramp up the new rocket's launch cadence.

Bruno had a 30-year career as an engineer and general manager for Lockheed Martin's ballistic missile programs before taking over as president and CEO of United Launch Alliance in August 2014. He arrived as SpaceX started making inroads with its partially reusable Falcon 9 rocket, and ULA's leading position in the US launch market looked to be in doubt.

Safety panel says NASA should have taken Starliner incident more seriously https://arstechnica.com/space/2025/12/safety-panel-says-nasa-should-have-taken-starliner-incident-more-seriously/ https://arstechnica.com/space/2025/12/safety-panel-says-nasa-should-have-taken-starliner-incident-more-seriously/#comments Mon, 22 Dec 2025 21:11:11 +0000 https://arstechnica.com/space/2025/12/safety-panel-says-nasa-should-have-taken-starliner-incident-more-seriously/ For the better part of two months last year, most of us had no idea how serious the problems were with Boeing's Starliner spacecraft docked at the International Space Station. A safety advisory panel found this uncertainty also filtered through NASA's workforce.

On its first Crew Test Flight, Boeing's Starliner delivered NASA astronauts Butch Wilmore and Suni Williams to the space station in June 2024. They were the first people to fly to space on a Starliner spacecraft after more than a decade of development and setbacks. The astronauts expected to stay at the ISS for one or two weeks, but ended up remaining in orbit for nine months after NASA officials determined it was too risky to return them to Earth in the Boeing-built crew capsule. Wilmore and Williams flew back to Earth last March on a SpaceX Dragon spacecraft.

The Starliner capsule was beset by problems with its maneuvering thrusters and pernicious helium leaks on its 27-hour trip from the launch pad to the ISS. For a short time, Starliner commander Wilmore lost his ability to control the movements of his spacecraft as it moved in for docking at the station in June 2024. Engineers determined that some of the thrusters were overheating and eventually recovered most of their function, allowing Starliner to dock with the ISS.

The first elements of ROS were to launch in 2027 so it would be ready for human habitation in 2028. Upon completion in the mid-2030s, the station would encompass seven shiny new modules, potentially including a private habitat for space tourists. It would be so sophisticated that the station could fly autonomously for months if needed.

Importantly, the Russian station was also to fly in a polar orbit at about 400 km. This would allow the station to fly over the entirety of Russia, observing the whole country. It would be important for national pride because cosmonauts would not need to launch from Kazakhstan anymore. Rather, rockets launching from the country's new spaceport in eastern Russia, the Vostochny Cosmodrome, would easily reach the ROS in its polar orbit.

Several new rockets made their first flights this year. Blue Origin's New Glenn was the most notable debut, with a successful inaugural launch in January followed by an impressive second flight in November, culminating in the booster's first landing on an offshore platform. Second on the list is China's Zhuque-3, a partially reusable methane-fueled rocket developed by the quasi-commercial launch company LandSpace. The medium-lift Zhuque-3 successfully reached orbit on its first flight earlier this month, and its booster narrowly missed landing downrange. We could add China's Long March 12A to the list if it flies before the end of the year. This will be the final Rocket Report of 2025, but we'll be back in January with all the news that's fit to lift.

Rocket Lab delivers for Space Force and NASA. Four small satellites rode a Rocket Lab Electron launch vehicle into orbit from Virginia early Thursday, beginning a government-funded technology demonstration mission to test the performance of a new spacecraft design, Ars reports. The satellites were nestled inside a cylindrical dispenser on top of the 59-foot-tall (18-meter) Electron rocket when it lifted off from NASA’s Wallops Flight Facility. A little more than an hour later, the rocket’s upper stage released the satellites one at a time at an altitude of about 340 miles (550 kilometers). The launch was the starting gun for a proof-of-concept mission to test the viability of a new kind of satellite called DiskSats, designed by the Aerospace Corporation.

In January, a small spacecraft built by a California-based company called Impulse Space launched along with a stack of other satellites on a Falcon 9 rocket. Upon reaching orbit, the rocket's upper stage sent the satellites zipping off on their various missions.

And so it went with the Mira spacecraft built by Impulse, which is known as an orbital transfer vehicle. Mira dropped off several small CubeSats and then performed a number of high-thrust maneuvers to demonstrate its capabilities. This was the second flight by a Mira spacecraft, so Impulse Space was eager to continue testing the vehicle in flight.

The executive order, titled "Ensuring American Space Superiority," states that the country must "pursue a space policy that will extend the reach of human discovery, secure the nation's vital economic and security interests, unleash commercial development, and lay the foundation for a new space age."

White House sets priorities

There is nothing Earth-shattering in the new executive order, as much of it builds on previously announced policies that span multiple administrations. There are some notable points in the document that clearly reflect the White House's priorities, though, and Isaacman's leadership of NASA.

NASA will soon find out if the Perseverance rover can really persevere on Mars https://arstechnica.com/space/2025/12/nasa-will-soon-find-out-if-the-perseverance-rover-can-really-persevere-on-mars/ https://arstechnica.com/space/2025/12/nasa-will-soon-find-out-if-the-perseverance-rover-can-really-persevere-on-mars/#comments Thu, 18 Dec 2025 18:12:18 +0000 https://arstechnica.com/space/2025/12/nasa-will-soon-find-out-if-the-perseverance-rover-can-really-persevere-on-mars/ When the Perseverance rover arrived on Mars nearly five years ago, NASA officials thought the next American lander to take aim on the red planet would be taking shape by now.

At the time, the leaders of the space agency expected this next lander could be ready for launch as soon as 2026—or more likely in 2028. Its mission would have been to retrieve Martian rock specimens collected by the Perseverance rover, then billed as the first leg of a multilaunch, multibillion-dollar Mars Sample Return campaign.

Here we are on the verge of 2026, and there's no sample retrieval mission nearing the launch pad. In fact, no one is building such a lander at all. NASA's strategy for a Mars Sample Return, or MSR, mission remains undecided after the projected cost of the original plan ballooned to $11 billion. If MSR happens at all, it's now unlikely to launch until the 2030s.

That night, just days before Christmas, the company successfully landed the first stage for the first time. The story behind this remarkable achievement is nowhere more fully told than in the book Reentry, authored by Ars Technica Senior Space Editor Eric Berger and published in 2024. To mark the tenth anniversary, Ars is reprinting a slightly condensed chapter from the book that tells the inside story of this landing. The chapter begins in June 2015 with a tragedy, the disintegration of a Falcon 9 rocket carrying the CRS-7 cargo supply mission for NASA. It was the first time a Falcon 9 had been lost in flight.

Seconds after the Dragon-bearing Falcon 9 rocket broke apart over the Atlantic Ocean, David Giger shouted into his headset, "Dragon is alive!"

In the decade since he joined the company straight out of graduate school, Giger had taken on management of the entire Dragon program, reporting directly to Elon Musk. He watched the CRS-7 launch from mission control in Hawthorne not with a particular role, but rather providing a leadership presence. Giger could sense the Dragon mission team, mostly younger engineers, freeze up as video showed debris from the rocket showering back to Earth. A lot of the people involved in the hairy early flights of Dragon, including the C2 mission in 2012, had moved on to other positions at SpaceX or departed.

Parts of this new observatory, named for NASA's first chief astronomer, recently completed a spate of tests to ensure it can survive the shaking and intense sound of a rocket launch. Engineers placed the core of the telescope inside a thermal vacuum chamber, where it withstood the airless conditions and extreme temperature swings it will see in space.

Then, on November 25, teams at NASA's Goddard Space Flight Center in Greenbelt, Maryland, joined the inner and outer portions of the Roman Space Telescope. With this milestone, NASA declared the observatory complete and on track for launch as soon as fall 2026.

For a long time, the majority of these companies revealed designs that looked a lot like SpaceX's Falcon 9 rocket.

The first of these copy cats, the medium-lift Zhuque-3 rocket built by LandSpace, launched earlier this month. Its primary mission was nominal, but the Zhuque-3 rocket failed its landing attempt, which is understandable for a first flight. Doubtless there will be more Chinese Falcon 9-like rockets making their debut in the near future.

However, over the last year, there has been a distinct change in announcements from China when it comes to new launch technology. Just as SpaceX is seeking to transition from its workhorse Falcon 9 rocket—which has now been flying for a decade and a half—to the fully reusable Starship design, so too are Chinese companies modifying their visions.

The company, named K2, announced the cash infusion on Thursday. K2's Series C fundraising round was led by Redpoint Ventures, with additional funding from investment firms in the United States, the United Kingdom, and Germany. K2 has now raised more than $400 million since its founding in 2022 and is on track to launch its first major demonstration mission next year, officials said.

K2 aims to take advantage of a coming abundance of heavy- and super-heavy-lift launch capacity, with SpaceX's Starship expected to begin deploying satellites as soon as next year. Blue Origin's New Glenn rocket launched twice this year and will fly more in 2026 while engineers develop an even larger New Glenn with additional engines and more lift capability.

Meanwhile, a second Mars orbiter is perilously close to running out of fuel, and the third mission is running well past its warranty.

Ground teams last heard from the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft on Saturday, December 6. "Telemetry from MAVEN had showed all subsystems working normally before it orbited behind the red planet," NASA said in a short statement. "After the spacecraft emerged from behind Mars, NASA's Deep Space Network did not observe a signal."

NASA said mission controllers are "investigating the anomaly to address the situation. More information will be shared once it becomes available."

This represents a major change in thinking from the world's leading space company and its founder, Elon Musk.

The Wall Street Journal and The Information first reported about a possible IPO last Friday, and Bloomberg followed that up on Tuesday evening with a report suggesting the company would target a $1.5 trillion valuation. This would allow SpaceX to raise in excess of $30 billion.

This is an enormous amount of funding. The largest IPO in history occurred in 2019, when the state-owned Saudi Arabian oil company began public trading as Aramco and raised $29 billion. In terms of revenue, Aramco is a top-five company in the world.

After key Russian launch site is damaged, NASA accelerates Dragon supply missions https://arstechnica.com/space/2025/12/after-key-russian-launch-site-is-damaged-nasa-accelerates-dragon-supply-missions/ https://arstechnica.com/space/2025/12/after-key-russian-launch-site-is-damaged-nasa-accelerates-dragon-supply-missions/#comments Wed, 10 Dec 2025 18:13:52 +0000 https://arstechnica.com/space/2025/12/after-key-russian-launch-site-is-damaged-nasa-accelerates-dragon-supply-missions/ With a key Russian launch pad out of service, NASA is accelerating the launch of two Cargo Dragon spaceships in order to ensure that astronauts on board the International Space Station have all the supplies they need next year.

According to the space agency's internal schedule, the next Dragon supply mission, CRS-34, is moving forward one month from June 2026 to May. And the next Dragon supply mission after this, CRS-35, has been advanced three months from November to August.

A source indicated that the changing schedules are a "direct result" of a launch pad incident on Thanksgiving Day at the Russian spaceport in Baikonur, Kazakhstan.

NASA astronauts will have their own droid when they go back to the Moon https://arstechnica.com/space/2025/12/lunar-outpost-rover-to-study-lunar-dust-alongside-artemis-astronauts-on-moon/ https://arstechnica.com/space/2025/12/lunar-outpost-rover-to-study-lunar-dust-alongside-artemis-astronauts-on-moon/#comments Tue, 09 Dec 2025 18:09:05 +0000 https://arstechnica.com/space/2025/12/lunar-outpost-rover-to-study-lunar-dust-alongside-artemis-astronauts-on-moon/ B-9 had Will Robinson. Twiki had Buck Rogers. And, of course, C-3PO and R2-D2 had Luke Skywalker. Now, in a scenario straight out of science fiction, MAPP will have whoever NASA names to the crew of the second Artemis mission to land on the moon.

The space agency has selected Lunar Outpost's Mobile Autonomous Prospecting Platform, or MAPP, to become the first robotic rover to operate on the moon alongside astronauts. Although its tasks will be far simpler than those of the robots seen on TV and in the movies, the autonomous four-wheeled MAPP will help scientists learn more about the crew's surroundings. Science instruments on the rover will characterize the surface plasma and behavior of the dust in the lunar environment.

"The Apollo era taught us that the further humanity is from Earth, the more dependent we are on science to protect and sustain human life on other planets," said Nicky Fox, NASA's associate administrator for science, in a statement. "By deploying these... science instruments on the lunar surface, our proving ground, NASA is leading the world in the creation of humanity's interplanetary survival guide to ensure the health and safety of our spacecraft and human explorers as we begin our epic journey back to the Moon."
