AI data centers in space sound great, but practically speaking, they may be next to impossible.
For tech bros, it sounds great. Two of the buzziest tech giants, SpaceX and NVIDIA, are partnering together to bring AI data centers into space using the just-announced Starmind AI1 satellite.
These 30-meter-tall satellites with a 75-meter solar-array wingspan will contain the latest NVIDIA Vera CPUs and Rubin GPUs. These will live in a Low Earth Orbit (LEO) of about 600 kilometers. For networking, it will use Starlink’s laser links. SpaceX says the first AI1 spacecraft will perform localized AI computing in orbit and relay results to Earth via Starlink.
According to SpaceX, AI1 is designed around a compute payload drawing up to 250 kW at peak and 175 kW on average. It will be solar-powered, unlike its Earth-bound competitors, which frequently require the construction of new power plants.

Starmind is not simply a conventional NVIDIA AI cluster launched into orbit. The effort hinges on integrating high-density accelerator hardware with a spacecraft platform capable of generating power, rejecting waste heat, surviving radiation, maintaining laser communications, and being produced in large quantities. None of that is easy.
Once in orbit, which will require SpaceX’s still-not-ready-for-prime-time Starship rockets to launch the estimated 2.3-metric-ton satellites, the satellites will work together.
Eventually, to reach SpaceX’s goal of a million (that’s not a typo, that’s a million) Starmind satellites, the two companies will need to design a standard …
