Ten days ago, in a moment of very high drama in orbit, NASA directed its astronauts living on the International Space Station to briefly seek emergency refuge in a Crew Dragon spacecraft.

Since then, neither the US space agency nor Roscosmos has provided additional public information about the situation in orbit. But according to sources who spoke to Ars, following the spectacle in space, the problem has been successfully fixed.

At issue were persistent cracks in a small area of the International Space Station attached to the Russian Zvezda service module, known as the PrK module. The problem has been ongoing since 2019, and Russian astronauts have been attempting various fixes, often using a sealant called Germetall-1.

Space Exploration Technologies, better known simply as SpaceX, became a publicly traded company on Friday nearly a quarter of a century after it was founded.

The company began trading on the NASDAQ exchange in New York City at $135 a share, valuing SpaceX at nearly $1.8 trillion. By the end of the trading day the company's shares were selling at $160.95, a respectable increase of more than 19 percent.

On paper, SpaceX founder Elon Musk became the world's first trillionaire, with his personal stake in the company valued at more than $700 billion. Because of the company's stock options plan, thousands of current and former employees became overnight millionaires. Employees at SpaceX have worked remarkably hard over the last 24 years, and now they will be richly compensated for having done so.

Welcome to Edition 8.45 of the Rocket Report! Even though we are now two weeks removed from the catastrophic loss of the New Glenn rocket and its LC-36A launch pad, it continues to dominate discussion in the space community. This week, NASA said it nominally plans to fly Blue Origin's test lander on New Glenn for the Artemis III mission, but officials quietly acknowledged that other launch vehicles, including Vulcan and the Falcon Heavy, could also get the job done. We'll obviously be watching closely.

On Tuesday, NASA announced the crew for the Artemis III mission, which is scheduled to be flown no earlier than summer 2027. As part of the announcement, space agency officials also discussed plans for the crew to dock with both a Blue Origin lander and a SpaceX Starship lander during the spaceflight in low-Earth orbit.

The presentation, although informative, still left open key questions about the landers' readiness and what exactly they'll look like. After the crew announcement, Ars sat down with Jeremy Parsons, NASA's Artemis program manager, to answer some of these questions.

This interview, conducted at NASA's Johnson Space Center, has been lightly edited for clarity.

The US space agency unveiled the crew for its Artemis III mission on Tuesday during an enthusiastic event at Johnson Space Center in Houston.

For this spaceflight into low-Earth orbit, which will see the Orion spacecraft rendezvous and dock with lunar lander prototypes, NASA chose an experienced, all-male crew with military backgrounds. They were revealed inside a darkened Teague Auditorium where hundreds of friends, family members, and NASA employees cheered enthusiastically.

The four crew members are:

A little more than five years ago, a shiny white Falcon 9 rocket made its debut flight, boosting a Cargo Dragon spacecraft to the International Space Station. Over the next year, it would launch a pair of astronaut missions and a handful of commercial spacecraft.

But since then, this first stage booster, designated B 1067, has mostly flown Starlink missions. It has launched them one after another, always returning safely to a drone ship before undergoing refurbishment and flying again. Sometimes it has flown twice in a single month.

On Monday morning, B 1067 once again took to the skies, launching 29 Starlink Internet satellites into low-Earth orbit from Florida. Upon landing on the A Shortfall of Gravitas drone ship in the Atlantic Ocean, the vehicle completed its 35th mission overall, retaining its title as fleet leader for SpaceX.

A former NASA engineer named John Muratore sat on console as launch director in early September 2016 as propellant flowed onto a Falcon 9 rocket in Florida. Ahead of a planned launch two days later, SpaceX was preparing for a static fire test of the vehicle.

Then, all of a sudden, the rocket exploded. "It came out of nowhere, and it was really violent," Muratore said. This fireball resulted in the destruction of the rocket, much of its launch site, and the AMOS-6 satellite already attached to the vehicle.

Nearly a decade later, on May 28, Blue Origin conducted a static fire test of a new rocket, with its larger New Glenn vehicle a few miles down the Florida coast. The company had gotten further into its test, reaching engine ignition, before its rocket also exploded.

The chief executive of Blue Origin, whose large New Glenn rocket exploded spectacularly less than a week ago at the company's launch site in Florida, vowed Monday night that the company would launch again before the end of 2026.

Writing on the social media site X, Blue Origin's Dave Limp said the company had been able to complete a preliminary survey of the LC-36A launch site.

"Now that we’ve had access to the pad and integration facility, we can share a bit of good news," Limp said. "The propellant farm, oxygen, liquid hydrogen and LNG tanks are all in good shape. This is good luck because these are very long lead items. The water tower is also good."

Getting around space, as it turns out, is kind of a big deal.

On Tuesday, Impulse Space, a company dedicated to improving space mobility, announced it has raised $500 million in Series D funding. Since it was founded five years ago by SpaceX veteran Tom Mueller, the company has now raised more than $1 billion.

"Timing is everything," Mueller said in an interview about the new round of funding. By this, he means the company has found its way into a lot of markets.

Forty years ago, the future seemed just around the corner—and the vehicle that was going to take us there was NASA's Space Shuttle. Originally envisioned as part of a larger integrated space transportation system, the shuttle was billed as a fully reusable vehicle, totally unlike the one-and-done capsules of the fading Apollo era, capable of making monthly (and perhaps even weekly) ferry flights to low Earth orbit.

The shuttle, it was hoped, would transform human space flight from extraordinary to mundane. Brands like Coke and Pepsi were quick to hop aboard and expand the Cola Wars into space, and there were even plans to blast Sesame Street's Big Bird into orbit.

The loss of Challenger in January 1986—carrying educator Christa McAuliffe, who would have been the first private citizen in space—put the kibosh on all of that. The shuttle, while fantastically advanced, would never be the vehicle to help humankind slip all of our surly bonds, so to speak. Even operating at its most frantic peak in 1985 just before Challenger's loss, the shuttle hardware managed a maximum of nine flights in one calendar year; for most of the 1990s, it performed at five or six flights per year. Civilians in space—to say nothing of Big Bird—would have to wait.

Thursday night's detonation of Blue Origin's New Glenn rocket during a static-fire test produced a spectacular fireball over Florida, sending shards of the rocket flying far and wide, into the sea and across the coastal scrubland nearby.

With sunrise on Friday teams from Blue Origin, the US Space Force, and NASA will be able to begin more thoroughly assessing the damage to Blue Origin's facilities and begin picking up pieces of the rocket.

On Thursday evening, Blue Origin attempted to test fire its massive New Glenn rocket at its Florida launch site, but something went very wrong after engine ignition. The super heavy lift rocket exploded in spectacular and disastrous fashion.

The static fire test was being filmed by NASASpaceflight.com on its Space Coast Live feed, which captured video of the conflagration that followed the destruction of the booster. The first stage of New Glenn, fueled with methane, produced a massive fireball above the launch site along the Florida coast, LC-36A. It is possibly the most dramatic and powerful rocket explosion since the Soviet Union's N1 rocket was destroyed during a launch attempt in 1969.

NASA officials announced contract awards for the initial elements of a lunar base on Tuesday, including two rovers that will provide mobility to astronauts.

With the series of announcements, NASA Administrator Jared Isaacman sought to maintain momentum around a Moon Base initiative revealed two months ago as part of the space agency's return to the Moon. "For those waiting patiently, the grand return is close at hand, and we will not slow down," he said.

The manager for the lunar base, Carlos Garcia-Galan, said the space agency had selected two companies, Astrolab and Lunar Outpost, to build approximately 1-ton rovers that would be ready for delivery to the Moon in 2028. Astrolab will receive $219 million for its "CLV-1" rover, and Lunar Outpost $220 million for its "Pegasus" rover, building upon initial contracts awarded two years ago. Each rover is expected to have a range of 200 km and be capable of driving autonomously, with guidance from operators on Earth, in addition to being driven by astronauts.

Up until a decade ago, China had never launched as many as 20 orbital rockets a year. But beginning in 2022, the Asian country launched 64 rockets and last year reached a record total of 93, marking it as the second-most productive space power in the world.

Further growth is anticipated from both the company's state-owned enterprises as well as a rapidly expanding number of private launch companies. There is nothing wrong with this, as China's rapid growth in launch has been mirrored by the United States and, in particular, SpaceX.

However there is an issue with these launches, as China appears to be ignoring long-established norms about disposing of the upper stages of rockets. These are the parts of the vehicle that separate from the first stage of a rocket and push a satellite or spacecraft into orbit.

NASA Administrator Jared Isaacman sent a long email to employees on Friday morning outlining several structural changes that are intended to make the sprawling agency more efficient and allow it to better accomplish major goals, such as returning to the Moon and building a base there.

"I believe it is imperative to concentrate resources towards the highest priority objectives in the National Space Policy and liberate the best and brightest from needless bureaucracy and obstacles that impede progress," Isaacman wrote in his 3,000-word letter.

Isaacman's message stressed that no one at NASA will lose their jobs, and no field centers will be closed as part of these changes. Rather, the overall intent is to improve operational efficiency and focus on the agency's core missions. Isaacman laid these out as: execute on the Artemis Program to return humans to the Moon; build an enduring Moon Base; develop a "Space Reactor Office" to get America underway on nuclear power in space; ignite an economy in low-Earth orbit; and build more X-planes and launch more science missions.

Welcome to Edition 8.42 of the Rocket Report! SpaceX nearly launched its Starship rocket on Thursday amid much pomp and circumstance in South Texas, only to be foiled by a ground system issue. Such delays are to be expected, with almost entirely new hardware on both the rocket and the ground side of things. The company will try again as soon as Friday evening, and as we discuss in this week's report, the stakes are quite high for SpaceX and much of the rest of the US spaceflight enterprise.

NASA confirmed Thursday that the Russian segment of the International Space Station has begun leaking atmosphere into space again. It's an old problem that NASA recently hoped was resolved.

For more than half a decade, engineers from Roscosmos and NASA have been tracking the leak rate from a small Russian module attached to the space station that leads to a docking port. The source of these leaks, microscopic structural cracks, have been difficult to find and address.

In January, NASA said that after multiple inspections and sealant applications, the pressure inside this segment, known as the PrK module, had reached a "stable configuration." The PrK module is essentially a transfer tunnel attached to the Zvezda Service Module on the Russian segment of the space station.

After nearly a quarter of a century operating as a private company, with its financial accounts a closely guarded secret, SpaceX on Wednesday afternoon released a detailed accounting of its business in a nearly 400-page S-1 filing with the US Securities and Exchange Commission.

SpaceX, founded in 2002 and still led by Elon Musk, submitted the filing in anticipation of an initial public offering of its stock as soon as June 12.

The document revealed no major surprises about the company's space operations, but there was a trove of details about its sprawling operations, which now encompass launch, spaceflight, space-based Internet, and, thanks to its recent acquisition of Musk's xAI, social media and AI.

It's difficult to know the true state of the Russian economy, both because the country's financial reporting is sparse and because official figures are unreliable. But things probably aren't great.

This week, Sweden's minister of foreign affairs, Maria Malmer Stenergard, shared her country's assessment that the Russian economy has likely contracted over the last five years amid the war in Ukraine. Inflation is also high, and international sanctions have cost Russia $450 billion since the onset of the war in February 2022. Russia's economy is currently smaller than that of Texas, Stenergard said.

By most measures, then, the economy is not in tip-top shape. Moreover, the war is draining a large amount of the country's financial resources, with defense spending reaching a post-Soviet record of about 7 percent of government spending.
