Elon Musk lays out a new vision as SpaceX acquires xAI

SpaceX CEO Elon Musk says he’s making space-based artificial intelligence the “immediate focus” of a newly expanded company that not only builds rockets and satellites, but also controls xAI’s generative-AI software and the X social-media platform.

That’s the upshot of today’s announcement that SpaceX has acquired xAI. The Information quoted unnamed sources as saying that xAI was valued at $250 billion, while SpaceX’s value was set at a trillion dollars. That would make SpaceX the most valuable private company in the world — but because Musk held a controlling interest in both companies, those valuations may be somewhat subjective.

Ross Gerber, an investment adviser who tracks Musk’s business dealings, quipped on X that the world’s richest person decided to go ahead with the acquisition after “a short negotiation with himself.”

Musk said the combination of SpaceX and xAI would facilitate the creation of a new constellation of orbital data centers. SpaceX is already seeking approval from the Federal Communications Commission to put up to a million satellites in low Earth orbit for such a constellation.

SpaceX wants to launch a million data center satellites

SpaceX founder Elon Musk wasn’t kidding about his plans to go big with orbital data centers: The company is asking the Federal Communications Commission to approve a plan to put up to a million satellites in orbit to process data for artificial intelligence applications.

“Launching a constellation of a million satellites that operate as orbital data centers is a first step towards becoming a Kardashev II-level civilization — one that can harness the sun’s full power — while supporting AI-driven applications for billions of people today and ensuring humanity’s multiplanetary future amongst the stars,” SpaceX said in an application filed with the FCC on Friday.

If realized, the plan could pose a challenge to AI titans including Microsoft, Amazon, Google and OpenAI — and to Seattle-area space companies such as Starcloud, Sophia Space and Jeff Bezos’ Blue Origin space venture, all of which are aiming to serve the emerging market for AI data centers.

On the other hand, it could be a boon for SpaceX’s manufacturing facility in Redmond, Wash., which produces the satellites for SpaceX’s Starlink broadband constellation; and for Musk’s xAI company, which has been the focus of merger talks as SpaceX considers an initial public offering. The Wall Street Journal quoted unidentified sources as saying that Musk decided to take SpaceX public in part to raise more capital to build orbital data centers and to help xAI.

Amazon asks FCC for more time to launch Leo satellites

Amazon says it’s been harder than expected to secure rides for its Amazon Leo broadband internet satellites, and now it’s asking the Federal Communications Commission for more time.

The request for an extension, filed today, asks the FCC to give Amazon until July 30, 2028, to deploy half of its 3,232 satellites in low Earth orbit. The current deadline is July 30, 2026.

Amazon said it’s spent more than $10 billion on its Leo constellation and has reserved more than 100 launches to get the satellites in their proper orbits. But it acknowledged that it’ll miss the original deadline, which was set in 2020 when the FCC gave the initial go-ahead for what was then known as Project Kuiper.

“Despite a historic reserve of launch capacity and deep investments in launch infrastructure, Amazon Leo has faced a shortage in the near-term availability of launches,” the company said. “This shortage has been driven by manufacturing disruptions, the failure and grounding of new launch vehicles, and limitations in spaceport capacity.”

Citing the launch availability gap, Amazon said it has had to reduce the production rate at its satellite manufacturing facility in Kirkland, Wash. “Amazon Leo is capable of consistently manufacturing 30 satellites per week — or over 1,500 satellites per year,” the company said. “To date, Amazon Leo has produced hundreds of flight-qualified satellites, and could readily have produced a multiple of this amount but for adjustments to its production schedule made in response to the delays in its launch manifest.”

Why NASA is going nuclear for a power play on the moon

Almost 60 years after America won the first space race, the moon is once again the focus of a competition between superpowers: Who’ll be the first to put a nuclear-powered base on the lunar surface?

And just as President John F. Kennedy set a goal of landing astronauts on the moon and bringing them back safely “before the decade is out,” NASA and the Department of Energy have set another end-of-decade deadline for developing a nuclear reactor for use on the moon. The current plan calls for demonstrating a 40-kilowatt power plant by 2030.

Why 2030? Roger Myers, an aerospace consultant who has been in the business of developing in-space power and propulsion systems for decades at NASA and Aerojet Rocketdyne, says the timing is tied to China’s ambition to set up its own moon base by 2035.

“China has announced many times in the last few years that they plan to land their astronauts, their taikonauts, on the surface of the moon by 2030, and they want to have a sustained presence on the surface of the moon by 2035,” he says in the latest episode of the Fiction Science podcast. “The United States has a decision to make: Do we want every human on the planet to look up every night and see just a Chinese flag? Or do we want them to see a Chinese and an American flag?”

Seattle-based Interlune is raising additional investment to support its campaign to identify and extract resources on the moon that can be brought back to Earth, starting with helium-3.

The fundraising effort came to light in a document filed with the Securities and Exchange Commission this week. The $5 million offering takes the form of a Simple Agreement for Future Equity, or SAFE, a contractual arrangement in which investors have the right to receive equity in the company at a later time.

In its initial filing on Jan. 28, Interlune reported that $500,000 of the offering had been sold to a set of six investors. The filing didn’t identify the investors.

In an emailed statement, Interlune CEO Rob Meyerson said the SAFE funding would help support the company’s preparations for the lunar missions ahead.

“Interlune has elected to raise $5 million on a Simple Agreement for Future Equity from existing and new investors to advance key technical milestones ahead of its next priced round,” Meyerson said. “We have several significant projects in the works, which we’re excited to announce shortly.”

Flight log: Blue Origin team leader flies standby to space

Jeff Bezos’ Blue Origin space venture sent six more people on a brief suborbital space trip today — including the director of Blue Origin’s New Shepard launch operations and training team.

The flight, known as NS-38, was Blue Origin’s 38th New Shepard mission overall, and the 17th mission that carried people.

Laura Stiles, who joined Blue Origin in 2013, was a late addition to the NS-36 crew. She filled a seat that was left open when one of the would-be spacefliers, Andrew Yaffe, had to bow out due to illness. Blue Origin said Yaffe will fly on a future New Shepard mission.

This was Stiles’ first trip to space, but she’s taken on several other roles associated with the New Shepard suborbital space program, including serving as a flight controller, a crew communicator and a trainer.

Stiles laughed for joy as she emerged from the New Shepard crew capsule at the end of the ride.

“There are so many people who have worked so hard for so many years with all their heart, all their soul, and I got to be there for everybody today,” she said. “The ride is incredible … We taught this training so many times, and it was so like … oh my God! The g’s, and the movement, and going through the clouds, and the Earth against the blackness. … We saw the moon, and things you can’t have pictured or imagined what it would be like to be up there.”

Today’s 10-minute flight was conducted at Blue Origin’s Launch Site One in West Texas. It followed Blue Origin’s standard procedure, with liftoff coming at 10:25 a.m. CT (8:25 a.m. PT). The reusable New Shepard booster sent the crew capsule to a height of 346,722 feet (65.7 miles or 105.7 kilometers) and then flew itself back to a landing pad.

Meanwhile, the crew got out of their seats to float in zero gravity and look out the windows at the black sky of space and the Earth below. They got back in their seats for a parachute-aided descent that ended with touchdown at 10:36 a.m. CT (8:36 a.m. PT).

Blue Origin plans ultra-fast satellite data network

Jeff Bezos’ Blue Origin space venture says it’ll be ramping up an ultra-high-speed satellite data network called TeraWave, which will compete with SpaceX’s Starlink network for business from data centers, large-scale enterprises and government customers.

The service appears to dovetail with Amazon Leo, the satellite-based broadband internet service that was Bezos’ brainchild while he served as Amazon’s CEO. Amazon Leo — previously known as Project Kuiper — promises downlink speeds of up to 1 gigabit per second (Gbps). In contrast, TeraWave is targeting higher-end data applications with symmetrical data speeds of up to 6 terabits per second (Tbps), a rate that’s 6,000 times faster.

In today’s announcement, Blue Origin said TeraWave’s constellation would consist of 5,408 laser-linked satellites in low Earth orbit (LEO) and medium Earth orbit (MEO). It plans to start deploying satellites in late 2027, presumably using the company’s New Glenn rockets.

Blue Origin’s plans are discussed in an application and technical annex filed today with the Federal Communications Commission. In its application, the company is seeking waivers from several regulatory requirements in order to get TeraWave off the ground quickly.

Starfish will set up disposal service for military satellites

Starfish Space has secured a $52.5 million contract from the U.S. Space Force’s Space Development Agency to dispose of military satellites at the end of their operational lives.

The Tukwila, Wash.-based startup says it’s the first commercial deal ever struck to provide “deorbit-as-a-service,” or DaaS, for a satellite constellation in low Earth orbit. In this case, the constellation is the Pentagon’s Proliferated Warfighter Space Architecture, which provides global communications access and encrypted connectivity for military missions. The contract calls for Starfish Space to launch the satellite disposal service in 2027.

“This is not research and development. This is an actual service, in a structure that allows that service to scale for this constellation, for an entire industry,” Starfish Space co-founder Trevor Bennett told me. He said the arrangement validates the Space Development Agency’s approach to building and maintaining its constellation, and also validates “the path that we can take with the industry at large.”

Starfish is developing a spacecraft called Otter that would be able to capture other satellites, maneuver them into different orbits, release them and then move on. In a deorbiting scenario, Otter would send the target satellite into a trajectory for atmospheric re-entry that wouldn’t pose a risk to other orbital assets.

NASA’s moon rocket makes the slow trip to its launch pad

NASA’s massive Space Launch System rocket crept toward its Florida launch pad today at a top speed of about 1 mph, marking the first step in a journey that will eventually send astronauts around the moon for the first time in more than 50 years.

The 4-mile trek to Launch Complex 39B at NASA’s Kennedy Space Center began at 7 a.m. ET (4 a.m. PT) and lasted until evening. Because the rocket with its mobile launcher stands more than 300 feet tall and weighs millions of pounds, the trip required the use of a crawler-transporter — the same vehicle used for the Apollo and space shuttle programs, now upgraded for NASA’s Artemis moon program.

Liftoff for the Artemis 2 mission could come as early as Feb. 6, but there’s lots to be done in the weeks ahead. After today’s rollout, the mission team will conduct a thorough checkout of the Space Launch System and its Orion crew spacecraft. Then there’ll be a “wet dress rehearsal,” during which the launch team will fuel the rocket and count down to T-minus 29 seconds.

“We have, I think, zero intention of communicating an actual launch date until we get through wet dress,” NASA Administrator Jared Isaacman told reporters.

Artemis 2 is slated to send three NASA astronauts and one Canadian astronaut on a 10-day journey tracing a figure-8 route around the moon. The trip will take them as far as 4,800 miles beyond the lunar far side — farther out than any human has gone before.

A decades-old rocket factory in Redmond, Wash., is due to be rebranded with a time-honored name: Rocketdyne.

If all goes according to plan, the facility will become part of a joint venture created under the terms of an $845 million deal involving L3Harris Technologies and AE Industrial Partners.

L3Harris took over the Redmond facility in 2023 when it acquired Aerojet Rocketdyne for $4.7 billion. Now L3Harris plans to sell a majority stake in its Space Propulsion and Power Systems business to AE Industrial, while retaining 40% ownership of the newly created Rocketdyne venture. The transaction is expected to close in the second half of 2026, subject to regulatory approvals and other conditions.
