Elon Musk revealed the AI1 satellite, a 70 m wingspan spacecraft carrying a 120 kW average (150 kW peak) AI compute payload powered by solar panels at 600 km orbit. It uses 110 m² of deployable radiators and interchangeable chip modules to run AI workloads off-grid.
- SpaceX's AI1 satellite has a 70m wingspan and delivers 120 kW average (150 kW peak) compute power using interchangeable chips from any vendor.
- Cooling requires 110 m² of radiators, far more efficient than the ISS's 422 m² for only 70 kW—though critics note Starlink's heat-rejection track record (1-3 kW per satellite) doesn't prove this scales.
- The reveal comes right before SpaceX's IPO targeting a $1.75 trillion valuation, alongside a $920 million-per-month deal with Google and FCC approval for up to a million such satellites.
- Skeptics like Sam Altman call the concept "ridiculous," citing launch costs, unfixable maintenance in orbit, and dependence on Starship becoming fully operational.
