Elon Musk recently provided a more detailed look at the initial design for SpaceX's planned AI data center satellites, offering fresh insights into the ambitious project that is a key driver behind the company's highly anticipated public listing.
In a 30-minute video posted on his social media platform, X, the SpaceX CEO outlined future plans, including continued development of the Starship rocket and a joint venture with Tesla Motors (TSLA) to build a "Terafab" facility aimed at manufacturing computer chips in the United States.
Musk also shared a rendering and specifications for what SpaceX calls the "AI1" satellite, the first version in a planned network of approximately one million satellites designed to provide advanced computing power for artificial intelligence from Earth's orbit.
Musk noted that this early-version satellite, equipped with massive solar panels spanning 230 feet (70 meters), would support an average computational load of 120 kilowatts, with a peak capacity of 150 kilowatts.
In a separate interview, SpaceX Chief Financial Officer Bret Johnsen stated that the initial AI satellites would utilize chips from Nvidia.
Drawing on SpaceX's experience building the Starlink system, Musk claimed that constructing data center satellites is simpler than manufacturing those for satellite internet services.
"An AI satellite is essentially a bunch of solar panels, a heat sink, and you still need some laser links, but you don't need the incredibly complex antenna arrays that Starlink satellites have," Musk said in the video. "The AI satellite is an easier design problem."
Musk added that data center satellites would need to be built larger than Starlink satellites.
He also showcased extensive expansion plans for SpaceX's facility in Bastrop, Texas, where the company currently manufactures user terminals for the Starlink system.
A slide presented named the facility "Gigasat," which would occupy over 11 million square feet across more than 1,000 acres of land.
Gigasat would consist of multiple warehouses for producing the large solar panels required for the data center satellites.
Despite its massive scale, the Gigasat expansion pales in comparison to the planned Terafab facility.
Musk stated in the video that the proposed Terafab would cover 100 million square feet, roughly ten times the size of Tesla's Austin Gigafactory.
A Wyoming-based limited liability company linked to Musk has been acquiring significant land in Grimes County, Texas, in preparation for the expected Terafab.
The push to build AI data center satellites is adding momentum to SpaceX's plans for an initial public offering, which has the potential to be the largest in history.
While SpaceX's newly acquired AI division has lagged behind competitors in developing chatbots, Musk has chosen to shift focus to infrastructure—namely the chips and data centers that power such systems.
SpaceX has recently reached agreements with Anthropic PBC and Alphabet (GOOGL) to sell them access to data centers and chips, resources that Musk's AI division is not yet fully utilizing.
Johnsen clarified that SpaceX is not abandoning its internal services, such as the Grok chatbot, but aims to monetize its spare computing capacity by leasing it out.
SpaceX has also entered into a potential acquisition agreement with AI startup Cursor through xAI, with plans to collaborate on code writing and computing power.
"Elon believes the future bottlenecks will be compute and power," Johnsen said in an interview with Musk ally Gavin Baker, discussing constraints on AI development. "We're already starting to see that."
