Why AI’s environmental footprint won’t disappear into orbit

AI companies like SpaceX, Amazon, and Google are pitching data centers in orbit, powered by endless solar energy. But according to The Conversation, the environmental case doesn't hold up once you factor in the full lifecycle. Each Starship launch burns over one thousand tonnes of liquid methane, releasing roughly eighty thousand tonnes of carbon dioxide—what twenty thousand cars emit in a year. Space-based systems demand massive cooling radiators, since orbital vacuum traps heat; satellites degrade rapidly there; and a single collision between the million-plus planned satellites could trigger cascading debris that would cripple orbital operations for decades. These proposals will have implications nobody yet understands.
