SpaceX has asked to operate up to one million AI satellites, but their direct waste heat would barely affect global temperature; the larger climate question is what launches and mass re-entry would put into the upper atmosphere

If the full Starmind system ever existed, its direct waste heat would be too small to become a major global climate driver. The filing seeks authority for a non-geostationary system of up to one million satellites between 500 and 2,000 kilometers altitude. The computers’ direct heat is not the main climate problemComputers turn almost all the electricity they use into heat. Starmind would use different spacecraft, potentially different launch vehicles and an unknown deployment cadence. A fleet approaching one million satellites would turn an emerging source of upper-atmosphere pollution into a planetary experiment without a validated model of the outcome.
