Most satellites are limited to kilowatt-scale solar power, constraining high-power applications in orbit. The unlimited vacuum in space allows a dipole magnetic confinement device to form the large plasma confinement regions fusion requires without bulky reactor hardware. With HTS magnets and declining launch costs, compact megawatt-class fusion in orbit is now within reach, unlocking an industrial space economy.
