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

1 August 2025 at 22:06

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

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

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

At $250 million, top AI salaries dwarf those of the Manhattan Project and the Space Race

1 August 2025 at 21:23

Silicon Valley's AI talent war just reached a compensation milestone that makes even the most legendary scientific achievements of the past look financially modest. When Meta recently offered AI researcher Matt Deitke $250 million over four years (an average of $62.5 million per year)—with potentially $100 million in the first year alone—it shattered every historical precedent for scientific and technical compensation we can find on record. That includes salaries during the development of major scientific milestones of the 20th century.

The New York Times reported that Deitke had cofounded a startup called Vercept and previously led the development of Molmo, a multimodal AI system, at the Allen Institute for Artificial Intelligence. His expertise in systems that juggle images, sounds, and text—exactly the kind of technology Meta wants to build—made him a prime target for recruitment. But he's not alone: Meta CEO Mark Zuckerberg reportedly also offered an unnamed AI engineer $1 billion in compensation to be paid out over several years. What's going on?

These astronomical sums reflect what tech companies believe is at stake: a race to create artificial general intelligence (AGI) or superintelligence—machines capable of performing intellectual tasks at or beyond the human level. Meta, Google, OpenAI, and others are betting that whoever achieves this breakthrough first could dominate markets worth trillions. Whether this vision is realistic or merely Silicon Valley hype, it's driving compensation to unprecedented levels.

The curious case of Russia’s charm offensive with NASA this week

1 August 2025 at 19:20

Although NASA and its counterpart in Russia, Roscosmos, continue to work together on a daily basis, the leaders of the two organizations have not held face-to-face meetings since the middle of the first Trump administration, back in October 2018.

A lot has changed in the nearly eight years since then, including the Russian invasion of Ukraine, the rocky departure of Roscosmos leader Dmitry Rogozin in 2022 who was subsequently dispatched to the front lines of the war, several changes in NASA leadership, and more.

This drought in high-level meetings was finally broken this week when the relatively new leader of Roscosmos, Roscosmos Director General Dmitry Bakanov, visited the United States to view the launch of the Crew-11 mission from Florida, which included cosmonaut Oleg Platonov. Bakanov has also met with some of NASA's human spaceflight leaders at Johnson Space Center in Houston.

India safely launches a $1.5 billion satellite for NASA

30 July 2025 at 17:18

After more than a decade of development, NASA's science leadership traveled to India this week for the launch of the world's most expensive Earth-observation satellite.

The $1.5 billion synthetic aperture radar imaging satellite, a joint project between NASA and the Indian space agency ISRO, successfully launched into orbit on Wednesday aboard that nation's Geosynchronous Satellite Launch Vehicle, a medium-lift rocket.

The mission, named NISAR (NASA-ISRO Synthetic Aperture Radar), was subsequently deployed into its intended orbit 464 miles (747 km) above the Earth's surface. From this Sun-synchronous orbit, it will collect data about the planet's land and ice surfaces two times every 12 days, including the infrequently visited polar regions in the Southern Hemisphere.

Lawmakers writing NASA’s budget want a cheaper upper stage for the SLS rocket

25 July 2025 at 11:30

Not surprisingly, Congress is pushing back against the Trump administration's proposal to cancel the Space Launch System, the behemoth rocket NASA has developed to propel astronauts back to the Moon.

Spending bills making their way through both houses of Congress reject the White House's plan to wind down the SLS rocket after two more launches, but the text of a draft budget recently released by the House Appropriations Committee suggests an openness to making some major changes to the program.

The next SLS flight, called Artemis II, is scheduled to lift off early next year to send a crew of four astronauts around the far side of the Moon. Artemis III will follow a few years later on a mission to attempt a crew lunar landing at the Moon's south pole. These missions follow Artemis I, a successful unpiloted test flight in 2022.

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

24 July 2025 at 12:12

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

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

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

As White House talks about impounding NASA funding, Congress takes the threat seriously

18 July 2025 at 20:54

This has been a good week for the US space agency in terms of the federal budget.

On Tuesday, a committee in the US House of Representatives passed a $24.8 billion budget bill for the coming fiscal year. Then, two days later a Senate committee passed a $24.9 billion budget for NASA. Both of these measures would keep funding more or less at the level of the current fiscal year and, for the most part, keep the space agency's programs going on their current trajectories.

These bills are not final. Both must move through the full House and Senate, and then be reconciled before going to President Trump for his signature. And time is running out, with fiscal year 2026 set to begin on October 1, just a little more than ten weeks from now.

After a partly successful test flight, European firm eyes space station mission

18 July 2025 at 16:00

Last month, the parachutes on Hélène Huby's small spacecraft failed to deploy, and the vehicle and its cargo crashed into the ocean on Earth.

It was both a success and a failure.

The success was that after Huby founded The Exploration Company in Europe, she managed to move nimbly with the "Mission Possible" spacecraft such that it cost less than $25 million to build and reached space in less than three years. The vehicle ticked off a number of successes in spaceflight before making a controlled descent through the atmosphere.

Congress moves to reject bulk of White House’s proposed NASA cuts

15 July 2025 at 22:05

A budget-writing panel in the House of Representatives passed a $24.8 billion NASA budget bill Tuesday, joining a similar subcommittee in the Senate in maintaining the space agency's funding after the White House proposed a nearly 25 percent cut.

The budget bills making their way through the House and Senate don't specify funding levels for individual programs, but the topline numbers—$24.8 billion in the House version and $24.9 billion the Senate bill—represent welcome news for scientists, industry, and space enthusiasts bracing for severe cuts requested by the Trump administration.

The spending plan passed Tuesday by the House Appropriations Committee's Subcommittee on Commerce, Justice, Science, and Related Agencies covers NASA and numerous other federal agencies. The $24.8 billion budget the House seeks for NASA is $6 billion more than the Trump administration's budget proposal, and keeps NASA's funding next year the same as this year.

We saw the heart of Pluto 10 years ago—it’ll be a long wait to see the rest

15 July 2025 at 11:15

NASA's New Horizons spacecraft got a fleeting glimpse of Pluto 10 years ago, revealing a distant world with a picturesque landscape that, paradoxically, appears to be refreshing itself in the cold depths of our Solar System.

The mission answered numerous questions about Pluto that have lingered since its discovery by astronomer Clyde Tombaugh in 1930. As is often the case with planetary exploration, the results from New Horizons' flyby of Pluto on July 14, 2015, posed countless more questions. First and foremost, how did such a dynamic world come to be so far from the Sun?

For at least the next few decades, the only resources available for scientists to try to answer these questions will be either the New Horizons mission's archive of more than 50 gigabits of data recorded during the flyby, or observations from billions of miles away with powerful telescopes on the ground or space-based observatories like Hubble and James Webb.

“It’s a heist”: Senator calls out Texas for trying to steal shuttle from Smithsonian

11 July 2025 at 00:05

A political effort to remove space shuttle Discovery from the Smithsonian and place it on display in Texas encountered some pushback on Thursday, as a US senator questioned the expense of carrying out what he described as a theft.

"This is not a transfer. It's a heist," said Sen. Dick Durbin (D-Ill.) during a budget markup hearing before the Senate Appropriations Committee. "A heist by Texas because they lost a competition 12 years ago."

In April, Republican Sens. John Cornyn and Ted Cruz, both representing Texas, introduced the "Bring the Space Shuttle Home Act" that called for Discovery to be relocated from the National Air and Space Museum's Steven F. Udvar-Hazy Center in northern Virginia and displayed at Space Center Houston. They then inserted a provision into the Senate version of the "One Big Beautiful Bill," which, to comply with Senate rules, was more vaguely worded but was meant to achieve the same goal.

RFK Jr.’s health department calls Nature “junk science,” cancels subscriptions

1 July 2025 at 22:21

Scientists at several federal agencies are losing access to scientific literature published by Springer Nature, which produces the prestigious journal Nature among many other high-profile titles.

That's according to a report Monday by Nature's news team, which is also published by Springer Nature, but is editorially independent.

According to the news outlet, spokespeople for NASA and the US Department of Agriculture (USDA) confirmed that agency scientists would no longer have access to Springer Nature journals. A USDA spokesperson said that it "has cancelled all contracts and subscriptions to Springer Nature. The journal [sic] is exorbitantly expensive and is not a good use of taxpayer funds." A government spending database also shows the Department of Energy (DOE) has dropped contracts with the publisher.

Ars reflects on Apollo 13 turning 30

29 June 2025 at 14:05

This year marks the 30th anniversary of the 1995 Oscar-winning film, Apollo 13, director Ron Howard's masterful love letter to NASA's Apollo program in general and the eponymous space mission in particular. So we're taking the opportunity to revisit this riveting homage to American science, ingenuity, and daring.

(Spoilers below.)

Apollo 13 is a fictional retelling of the aborted 1970 lunar mission that became a "successful failure" for NASA because all three astronauts made it back to Earth alive against some pretty steep odds. The film opens with astronaut Jim Lovell (Tom Hanks) hosting a watch party in July 1969 for Neil Armstrong's historic first walk on the Moon. He is slated to command the Apollo 14 mission, and is ecstatic when he and his crew—Ken Mattingly (Gary Sinise) and Fred Haise (Bill Paxton)—are bumped to Apollo 13 instead. His wife, Marilyn (Kathleen Quinlan) is more superstitious and hence less thrilled: "It had to be 13." To which her pragmatic husband replies, "It comes after 12."

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

27 June 2025 at 13:00

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

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

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

NASA tested a new SLS booster that may never fly, and the end of it blew off

26 June 2025 at 22:36

NASA's Space Launch System appears to have a finite shelf life. The Trump administration wants to cancel it after just three launches, while the preliminary text of a bill making its way through Congress would extend it to five flights.

But chances are low the Space Launch System will make it to nine flights, and if it does, it's questionable that it would reach that point before 2040. The SLS rocket is a core piece of NASA's plan to return US astronauts to the Moon under the Artemis program, but the White House seeks to cancel the program in favor of cheaper commercial alternatives.

For the second time in less than a week, NASA test-fired new propulsion hardware Thursday that the agency would need to keep SLS alive. Last Friday, a new liquid-fueled RS-25 engine ignited on a test stand at NASA's Stennis Space Center in Mississippi. The hydrogen-fueled engine is the first of its kind to be manufactured since the end of the Space Shuttle program. This particular RS-25 engine is assigned to power the fifth flight of the SLS rocket, a mission known as Artemis V.
