Almost exactly two years ago, as it prepared for the next generation of human spaceflight, NASA chose a pair of private companies to design and develop new spacesuits. These were to be new spacesuits that would allow astronauts to both perform spacewalks outside the International Space Station as well as walk on the Moon as part of the Artemis program.

Now, that plan appears to be in trouble, with one of the spacesuit providers—Collins Aerospace—expected to back out, Ars has learned. It's a blow for NASA, because the space agency really needs modern spacesuits.

NASA's Apollo-era suits have long been retired. The current suits used for spacewalks in low-Earth orbit are four decades old. "These new capabilities will allow us to continue on the ISS and allows us to do the Artemis program and continue on to Mars," said the director of Johnson Space Center, Vanessa Wyche, during a celebratory news conference in Houston two years ago.

A small spacecraft landed in Inner Mongolia on Tuesday, bringing samples from the far side of the Moon back to Earth.

This was not China's first robotic mission to return a few pounds of dust and pebbles from the lunar surface—that came with the Chang'e 5 mission in December 2020. However, this was the first time any space program in the world returned material from the Moon's far side.

The successful conclusion of this mission, which launched from Earth nearly two months ago, marked another significant achievement for China's space program as the country sets its sights on landing humans on the Moon by the year 2030.

Peter Beck has been having a pretty great June. Earlier this month, he was made a Knight Companion of the New Zealand Order of Merit. Then, Sir Peter Beck presided as Rocket Lab launched its 50th Electron rocket, becoming the fastest company to launch its 50th privately developed booster.

Finally, last week, Rocket Lab revealed that it had signed its largest launch contract ever: 10 flights for the Japanese Earth-observation company Synspective. Ars caught up with Beck while he was in Tokyo for the announcement. What follows is a lightly edited transcript of our conversation, which touches on a variety of launch-related issues.

Ars Technica: Hi Pete. We've talked about competition in small launch for years. But when I tally up the record of some of your US competitors—Firefly, Astra, Relativity Space, Virgin Orbit, and ABL—they're 7-for-21 on launch attempts. And if you remove the now-retired rockets, it's 1-for-6. Some of these competitors have, or did, exist for a decade. What does this say about the launch business?

In an update released late Friday evening, NASA said it was "adjusting" the date of the Starliner spacecraft's return to Earth from June 26 to an unspecified time in July.

The announcement followed two days of long meetings to review the readiness of the spacecraft, developed by Boeing, to fly NASA astronauts Butch Wilmore and Suni Williams to Earth. According to sources, these meetings included high-level participation from senior leaders at the agency, including Associate Administrator Jim Free.

This "Crew Flight Test," which launched on June 5 atop an Atlas V rocket, was originally due to undock and return to Earth on June 14. However, as engineers from NASA and Boeing studied data from the vehicle's problematic flight to the International Space Station, they have waved off several return opportunities.

The owner of a home in southwestern Florida has formally submitted a claim to NASA for damages caused by a chunk of space debris that fell through his roof in March.

The legal case is unprecedented—no one has evidently made such a claim against NASA before. How the space agency responds will set a precedent, and that may be important in a world where there is ever more activity in orbit, with space debris and vehicles increasingly making uncontrolled reentries through Earth's atmosphere.

Alejandro Otero, owner of the Naples, Florida, home struck by the debris, was not home when part of a battery pack from the International Space Station crashed through his home on March 8. His son Daniel, 19, was home but escaped injury. NASA has confirmed the 1.6-pound object, made of the metal alloy Inconel, was part of a battery pack jettisoned from the space station in 2021.

Welcome to Edition 6.49 of the Rocket Report! I want to open this week's report with a hearty congratulations to Rocket Lab for the company's 50th launch since Electron's debut in 2017. This is a fine achievement for a company founded in New Zealand, a country with virtually no space program.

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).

Electron celebrates its 50th. On Thursday, Rocket Lab launched its 50th Electron mission, "No Time Toulouse."  The mission successfully deployed five Internet-of-Things satellites for the French company Kinéis. This is a nice milestone for the company founded by Peter Beck in New Zealand. With this mission, Rocket Lab becomes the fastest company to go from one launch to 50 launches of a privately developed rocket, surpassing even SpaceX. The company's first Electron mission came about seven years ago.

Last week, during our inaugural Ars Live event, Quilty Space director of research Caleb Henry joined Ars space editor Eric Berger for a discussion of SpaceX's Starlink and other satellite internet systems. We discussed Starlink's rapid road to profitability—it took just five years from the first launch of operational satellites—and the future of the technology.

One of the keys to Starlink's success is its vertical integration as a core business at SpaceX, which operates the world's only reusable rocket, the Falcon 9. This has allowed the company not just to launch a constellation of 6,000 satellites—but to do so at relatively low cost.

"At one point, SpaceX had publicly said that it was $28 million," Henry said of the company's target for a Falcon 9 launch cost. "We believe today that they are below $20 million per launch and actually lower than that... I would put it in the mid teens for how much it costs them internally. And that's going down as they increase the reuse of the vehicle. Recently, they've launched their 20th, maybe 21st, use of a first-stage rocket. And as they can amortize the cost of the booster over a greater number of missions, that only helps them with their business case."

NASA and Boeing will take an additional four days to review all available data about the performance of the Starliner spacecraft before clearing the vehicle to return to Earth, officials said Tuesday.

Based on the new schedule, which remains pending ahead of final review meetings later this week, Starliner would undock at 10:10 pm ET on Tuesday, June 25, from the International Space Station (02:10 UTC on June 26). This would set up a landing at 4:51 ET on June 26 (08:51 UTC) at the White Sands Test Facility in New Mexico.

During a news conference on Tuesday, the program manager for NASA's Commercial Crew Program, Steve Stich, said the four-day delay in the spacecraft's return would "give our team a little bit more time to look at the data, do some analysis, and make sure we're really ready to come home."

Few people were happier with the successful outcome of last week's test flight of SpaceX's Starship launch system than a NASA engineer named Catherine Koerner.

In remarks after the spaceflight, Koerner praised the "incredible" video of the Starship rocket and its Super Heavy booster returning to Earth, with each making a soft landing. "That was very promising, and a very, very successful engineering test," she added, speaking at a meeting of the Space Studies Board.

A former flight director, Koerner now manages development of the "exploration systems" that will support the Artemis missions for NASA—a hugely influential position within the space agency. This includes the Space Launch System rocket, NASA's Orion spacecraft, spacesuits, and the Starship vehicle that will land on the Moon.

On Tuesday, Stoke Space announced the firing of its first stage rocket engine for the first time earlier this month, briefly igniting it for about two seconds. The company declared the June 5 test a success because the engine performed nominally and will be fired up again soon.

"Data point one is that the engine is still there," said Andy Lapsa, chief executive of the Washington-based launch company, in an interview with Ars.

The test took place at the company's facilities in Moses Lake, Washington. Seven of these methane-fueled engines, each intended to have a thrust of 100,000 pounds of force, will power the company's Nova rocket. This launch vehicle will have a lift capacity of about 5 metric tons to orbit. Lapsa declined to declare a target launch date, but based on historical developmental programs, if Stoke continues to move fast, it could fly Nova for the first time in 2026.

On Saturday, the VSS Unity space plane made its final flight, carrying four passengers to an altitude of 54.4 miles (87.5 km) above the New Mexico desert. The spacecraft will now be retired after just seven commercial space flights, all made within the last year.

Although the flight was characterized by its chief executive Michael Colglazier as a "celebratory moment" for Virgin Galactic, the company now finds itself at a crossroads.

After an impressive but brief flurry of spaceflight activity—seven human spaceflights in a year, even to suborbital space, is unprecedented for a private company—Virgin Galactic will now be grounded again for at least two years. That's because Colglazier and Virgin Galactic are betting it all on the development of a future "Delta class" of spaceships modeled on VSS Unity.

NASA and the Russian space agency, Roscosmos, still have not solved a long-running and worsening problem with leaks on the International Space Station.

The microscopic structural cracks are located inside the small PrK module on the Russian segment of the space station, which lies between a Progress spacecraft airlock and the Zvezda module. After the leak rate doubled early this year during a two-week period, the Russians experimented with keeping the hatch leading to the PrK module closed intermittently and performed other investigations. But none of these measures taken during the spring worked.

"Following leak troubleshooting activities in April of 2024, Roscosmos has elected to keep the hatch between Zvezda and Progress closed when it is not needed for cargo operations," a NASA spokesperson told Ars. "Roscosmos continues to limit operations in the area and, when required for use, implements measures to minimize the risk to the International Space Station."

Welcome to Edition 6.47 of the Rocket Report! The monumental news of late is that Boeing's Starliner spacecraft not only successfully launched on an Atlas V rocket, but then subsequently docked with the International Space Station. Congratulations to all involved. It's been a long road to get here.

Firefly lands massive launch contract. Firefly Aerospace announced Wednesday that it has signed a multi-launch agreement with Lockheed Martin for 25 launches on Firefly’s Alpha rocket through the end of this decade. This agreement commits Lockheed Martin to 15 launch reservations and 10 optional launches. Alpha will launch Lockheed Martin spacecraft into low-Earth orbit from Firefly’s facilities on the West and East Coast. The first mission will launch on Alpha flight 6, from Firefly’s SLC-2 launch site at the Vandenberg Space Force Base later this year.

A little more than a day after launching into space, Boeing's Starliner spacecraft flew up to the International Space Station and docked with the orbiting laboratory on Thursday.

The journey through space was not always easy. In the immediate hours after launch on Wednesday, the spacecraft was beset by two helium leaks in its propulsion system. Then, on Thursday, several of Starliner's spacecraft thrusters went offline for a time. Far more often than originally planned, spacecraft commander Butch Wilmore had to take manual control of Starliner while engineers on the ground worked on these and other issues.

However, at 1:34 pm ET on Thursday, Wilmore and the mission's other crew member, Suni Williams, successfully docked with the space station. A couple of hours later, they floated through the hatch, making a triumphant entry onto the station—and making history.

SpaceX began launching operational Starlink satellites five years ago this month. Since then, the company has been rapidly developing its constellation of broadband satellites in low-Earth orbit. SpaceX has now launched about 6,000 satellites with its Falcon 9 rocket and has delivered on its promise to provide fast Internet around the world. Today, the company is the largest satellite operator in the world by a factor of 10.

But is this massive enterprise to deliver Internet from space profitable?

According to a new report by Quilty Space, the answer is yes. Quilty built a model to assess Starlink's profitability. First, the researchers assessed revenue. The firm estimates this will grow to $6.6 billion in 2024, up from essentially zero just four years ago. In addition to rapidly growing its subscriber base of about 3 million, SpaceX has also managed to control costs. Based upon its model, therefore, Quilty estimates that Starlink's free cash flow from the business will be about $600 million this year.
