INTRO: As artificial intelligence drives the need for vastly more computing storage and processing power, interest in space-based data centers has spiked.

Although several startup companies, such as Starcloud, have begun to address this problem, the idea has also attracted the interest of tech barons. In May, it emerged that former Google chief executive Eric Schmidt acquired Relativity Space due to his interest in space-based data centers. Then, earlier this month, Amazon founder Jeff Bezos predicted that gigawatt-scale data centers will be built in space within the next 10 to 20 years.

Now, Elon Musk, whose SpaceX owns and operates significantly more space-based infrastructure than any other company or country in the world, has also expressed interest in the technology.

After Ars wrote a story on the potential of autonomous assembly to construct large data centers in space, Musk responded on X by saying that Starlink satellites could be used for this purpose. “Simply scaling up Starlink V3 satellites, which have high speed laser links would work,” he said on the social media site X. “SpaceX will be doing this.”

Musk’s interest in space-based data centers significantly raises the profile of the nascent industry. Proponents of the idea say the advantages are clear: free, limitless power from the Sun and none of the messy environmental costs of building these facilities on Earth (where opposition is starting to grow). Critics say it is economically impractical to build these facilities in space and that supporters underestimate the technology needed to make it work.

SpaceX’s Starlink constellation has already defied some of this conventional wisdom by delivering high-speed broadband to millions of customers around the world while making a profit. So if Musk believes the Starlink architecture can be applied to data centers, it will be difficult for the industry to ignore... (MORE - detail)

Elon posted about this today, in the course of a conversation with Cathie Wood of Ark-Invest:

"A major additional factor should be considered.

Satellites with localized AI compute, where just the results are beamed back from low-latency, sun-synchronous orbit, will be the lowest cost way to generate AI bitstreams in <3 years.

And by far the fastest way to scale within 4 years, because easy sources of electrical power are already hard to find on Earth. 1 megaton/year of satellites with 100kW per satellite yields 100GW of AI added per year with no operating or maintenance cost, connecting via high-bandwidth lasers to the Starlink constellation.

The level beyond that is constructing satellite factories on the Moon and using a mass driver (electromagnetic railgun) to accelerate AI satellites to lunar escape velocity without the need for rockets. That scales to >100TW/year of AI and enables non-trivial progress towards becoming a Kardashev II civilization."

Yep, Sabine's right. Elon's going crazy again!

Eric Berger just published an article that explains Elon's plans and tied them together with SpaceX going public. And Elon just wrote on X that Eric's article is accurate!

(Highlighting by me)

"The Wall Street Journal and The Information first reported about a possible IPO last Friday, and Bloomberg followed that up on Tuesday evening with a report suggesting the company would target a $1.5 trillion valuation.... for investors, space is the final frontier.

...The decision is surprising because Musk has, for so long, resisted going public with SpaceX...

A significant shift in recent years has been the rise of artificial intelligence, which Musk has been involved in since 2015, when he co-founded OpenAI...

How can SpaceX play in this space? In the near term, the company plans to develop a modified version of the Starlink satellite to serve as a foundation for building data centers in space...

...SpaceX is expected to have in the neighborhood of $22 to $24 billion in revenue next year. That is a lot of money—it’s on par with NASA’s annual budget, for example, and SpaceX can deploy its capital far, far more efficiently than the government can. So the company will be able to accomplish a lot. But with a large infusion of cash, SpaceX will be able to go much faster...

Abhi Tripathi, a long-time SpaceX employee who is now director of mission operations at the UC Berkeley Space Sciences Laboratory, believes that once Musk realized Starlink satellites could be architected into a distributed network of data centers, the writing was on the wall...

Musk also believes that a larger and more financially robust SpaceX is necessary to undertake the settling of Mars. He understands that NASA will not pay for this...

...Taking SpaceX public now is a bet that he can marshal the resources now, during his lifetime, to make Mars City One a reality....
