Look, no one said building a large harvester to roam around the Moon and sift through hundreds of tons of regolith to retrieve small amounts of helium-3 would be easy. And that's to say nothing of the enormous challenge of processing and then launching any of this material from the lunar surface before finally landing it safely on Earth.

If we're being completely honest, doing all of this commercially is a pretty darn difficult row to hoe. Many commercial space experts dismiss it out of hand. So that's why it's gratifying to see that a company that is proposing to do this, Interlune, is taking some modest steps toward this goal.

Moreover, recent changes in the tides of space policy may also put some wind in the sails of Interlune and its considerable ambitions.

Axiom Space plans to launch its fourth mission on Tuesday, June 10 — a mission that CEO Tejpaul Bhatia described as “a little bit of a victory lap.”

A robotic lander developed by a Japanese company named ispace plummeted to the Moon's surface Thursday, destroying a small rover and several experiments intended to demonstrate how future missions could mine and harvest lunar resources.

Ground teams at ispace's mission control center in Tokyo lost contact with the Resilience lunar lander moments before it was supposed to touch down in a region called Mare Frigoris, or the Sea of Cold, a basaltic plain in the Moon's northern hemisphere.

A few hours later, ispace officials confirmed what many observers suspected. The mission was lost. It's the second time ispace has failed to land on the Moon in as many tries.

Negotiations over the US federal budget for fiscal year 2026 are in the beginning stages, but when it comes to space, the fault lines are already solidifying in the Senate.

The Trump White House released its budget request last Friday, and this included detailed information about its plans for NASA. On Thursday, just days later, the US Senate shot back with its own budget priorities for the space agency.

The US budget process is complicated and somewhat broken in recent years, as Congress has failed to pass a budget on time. So, we are probably at least several months away from seeing a final fiscal year 2026 budget from Congress. But we got our first glimpse of the Senate's thinking when the chair of the Committee on Commerce, Science, and Transportation, Sen. Ted Cruz (R-Texas) released his "legislative directives" for NASA on Thursday

A remarkable schoolyard brawl erupted online Thursday between President Donald Trump and his former "First Buddy" Elon Musk during which the pair traded insults and barbs. The war of words reached a crescendo during the afternoon when Trump threatened Musk's federal contracts.

"The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon's Governmental Subsidies and Contracts. I was always surprised that Biden didn't do it!" Trump wrote on his social media network, Truth Social, at 2:37 pm ET.

Anyone with a reasonable grasp of reality understood that the "bromance" between the president of the United States and the most wealthy person in the world was going to blow up at some point, but even so, the online brouhaha that has played out Thursday is spectacular—at one point Musk suggested that Trump was in the Epstein files, for goodness' sake.

In a revealing interview published by the All-In Podcast on Wednesday, the private astronaut nominated to lead NASA, Jared Isaacman, spoke at length on what he thought about the nomination process, how he would have led NASA, and the factors that led to the abrupt rescission of his nomination by President Trump.

"I got a call Friday, of last week, that the president has decided to go in a different direction," Isaacman said. "It was a real bummer."

It was a real bummer for most of the space community, myself included. To be clear, I am biased. I have gotten to know Isaacman over the last five years rather well, talking with him about his passion for spaceflight, what is working, and what is not. What I have discovered in Isaacman is a person who cares deeply about the future of US spaceflight and wants to make a meaningful contribution to its advancement. To see him done wrong like this, well, it's a very sordid affair.

Researchers estimate that MoM z14 was created 280 million years after the Big Bang, 10 million years earlier than the previous most primitive galaxy recorded.

I did not expect to feature NASA astronaut Nichole Ayers in the Tuesday Telescope so soon, but a recent photo she shared is just sublime. (In case you missed it, we wrote about her photo of lightning from space about a month ago.)

This week Ayers has a time-lapse sequence she captured from the Cupola as the International Space Station soared near Central and South America.

"Soooooo much going on in this picture," Ayers wrote on the social media site X. "You can see Nicaragua, Costa Rica, and Panama, with South America off in the distance."

The Trump administration has confirmed that it is pulling the nomination of private astronaut Jared Isaacman to lead NASA.

First reported by Semafor, the decision appears to have been made because Isaacman was not politically loyal enough to the Trump administration.

"The Administrator of NASA will help lead humanity into space and execute President Trump’s bold mission of planting the American flag on the planet Mars," Liz Huston, a White House Spokesperson, said in a statement released Saturday. "It's essential that the next leader of NASA is in complete alignment with President Trump’s America First agenda and a replacement will be announced directly by President Trump soon."

SpaceX made some progress on another test flight of the world's most powerful rocket Tuesday, finally overcoming technical problems that plagued the program's two previous launches.

But minutes into the mission, SpaceX's Starship lost control as it cruised through space, then tumbled back into the atmosphere somewhere over the Indian Ocean nearly an hour after taking off from Starbase, Texas, the company's privately owned spaceport near the US-Mexico border.

SpaceX's next-generation rocket is designed to eventually ferry cargo and private and government crews between the Earth, the Moon, and Mars. The rocket is complex and gargantuan, wider and longer than a Boeing 747 jumbo jet, and after nearly two years of steady progress since its first test flight in 2023, this has been a year of setbacks for Starship.

On Tuesday afternoon, just a few hours before a launch attempt of the ninth flight test of SpaceX's Starship vehicle, Elon Musk spoke with Ars Technica Senior Space Editor Eric Berger to talk about where his space company goes from here.

In recent weeks, Musk has dialed back his focus on politics and said he wants to devote the majority of his time to SpaceX and his other companies. So what does that mean?

The conversation came just ahead of the opening of Starship's launch window, at 6:30 pm CT (23:30 UTC) in South Texas. Here is a lightly edited transcript of the interview.

In recent written testimony to a US House of Representatives subcommittee that oversees the military, the senior official responsible for purchasing launches for national security missions blistered one of the country's two primary rocket providers.

The remarks from Major General Stephen G. Purdy, acting assistant secretary of the Air Force for Space Acquisition and Integration, concerned United Launch Alliance and its long-delayed development of the large Vulcan rocket.

"The ULA Vulcan program has performed unsatisfactorily this past year," Purdy said in written testimony during a May 14 hearing before the House Armed Services Committee's Subcommittee on Strategic Forces. This portion of his testimony did not come up during the hearing, and it has not been reported publicly to date.

The Federal Aviation Administration gave the green light Thursday for SpaceX to launch the next test flight of its Starship mega-rocket as soon as next week, following two consecutive failures earlier this year.

The failures set back SpaceX's Starship program by several months. The company aims to get the rocket's development back on track with the upcoming launch, Starship's ninth full-scale test flight since its debut in April 2023. Starship is central to SpaceX's long-held ambition to send humans to Mars and is the vehicle NASA has selected to land astronauts on the Moon under the umbrella of the government's Artemis program.

In a statement Thursday, the FAA said SpaceX is authorized to launch the next Starship test flight, known as Flight 9, after finding the company "meets all of the rigorous safety, environmental and other licensing requirements."

Rotating detonation rocket engine takes flight. On Wednesday, US-based propulsion company Venus Aerospace completed a short flight test of its rotating detonation rocket engine at Spaceport America in New Mexico, Ars reports. It is believed to be the first US-based flight test of an idea that has been discussed academically for decades. The concept has previously been tested in a handful of other countries, but never with a high-thrust engine.

When SpaceX first launched the Starship, it blew up soon after liftoff. Since then, the world’s most powerful rocket has flown seven more times, with each test flight showing huge improvements in some areas of the vehicle’s design, but issues in others. One of the major achievements so far has involved the launch tower catching […]
