SpaceX is targeting late 2027 for its first demonstrations of orbital AI computing, accelerating a timeline that its own S-1 filing had pegged for 2028. The company filed with the FCC in January 2026 for a constellation of up to 1 million orbital data center satellites.
What SpaceX is actually building
The orbital data center satellites are designed to sit in low-Earth orbit, delivering hundreds of gigawatts of AI computing power. They’d run on solar energy with advanced thermal management systems to handle the brutal temperature swings of space.
In February 2026, SpaceX integrated xAI into its operations. The merger was an acknowledgment that Earth-based data centers are hitting hard limits on power consumption and cooling capacity. Once Starship reaches full operational scale, SpaceX anticipates it could facilitate 100 gigawatts of annual orbital compute additions.
