Each satellite must carry 72 Rubin GPUs and 36 Vera processors under 250 kW of peak power. The prototype is expected in early 2027, with a constellation of one million computing nodes on the horizon.
SpaceX and Nvidia announced in early August the joint development of Starmind AI1, a satellite designed as an orbital computing node. The spacecraft is to carry a space-adapted version of Nvidia's NVL72 system, i.e. 72 Rubin graphics processors and 36 Vera processors in a rack-scale architecture, the same one that equips the most recent terrestrial data centers.
To power this package, SpaceX says it has increased the satellite's peak power by about 67%, down to some 250 kW. Elon Musk confirmed during an earnings presentation that the company is sticking exclusively to Nvidia for this architecture.
The announced schedule calls for prototype testing in early 2027 and mass production later in the year. The stated long-term goal is the measure of the bet: a constellation of up to one million satellites, each operating as an independent computing unit, to form a planetary distributed supercomputer in low Earth orbit.
