Stampede is a satellite constellation running on-orbit GPU data centers powered by solar energy in low Earth orbit.

Cowboy Space develops orbital AI data centers powered by solar energy in low Earth orbit.
Cowboy Space Corporation is developing an integrated system of satellites and rockets to run high-performance AI compute in low Earth orbit, where abundant solar power and radiative cooling bypass terrestrial grid and cooling constraints. Its Stampede constellation of satellites harnesses solar power to run on-orbit GPU data centers, and its launch-vehicle upper stage is designed to become a one-megawatt data center in orbit.
The company was founded in 2024 by Baiju Bhatt, co-founder and former co-CEO of Robinhood, originally as Aetherflux to develop space-based solar power before expanding into orbital compute and launch infrastructure. It targets AI hyperscalers and national-security customers facing multi-year terrestrial grid connection lead times.
