SpaceX has provided some details about its AI1 satellite, which it calls an orbital data center.
Key facts
- The satellite is expected to have a wingspan of 70 meters, and a deployed height of 20 meters
- Founder and CEO Elon Musk added: “What they're showing here is kind of a draft version of Version One of the SpaceX AI satellite, AI1
- The assumptions here are 250W per sq m for the solar array, and about 1,400W per sqm for the radiators
- Over time, they think they can do about 250W and 1,400W, respectively
Summary
The company provided updates about the size and power capacity of the system, ahead of a much-anticipated IPO this Friday. "First, you've got to make something compelling, and we thought that the right place is around the 150kW peak power level," Ian Dahl, director of satellite engineering, said in a promotional video ahead of the IPO. "But as they start to look at workloads with their experience with xAI, they get to see that they can support 120kW of average compute.
