Space-Based Power
Generating power in space and beaming it where it is needed — from the arrays that power a station to the concept of space solar-power satellites that would collect sunlight in orbit and send it to Earth.
In brief
Generating and distributing power in space.
In this domain
- Solar Power SatelliteInfrastructureConcept
A large satellite that collects sunlight in orbit — where the Sun always shines — and beams the energy to receivers on the ground as microwaves. Small-scale power-beaming has been demonstrated; a full system remains a concept.
- Surface Fission PowerInfrastructureIn development
Compact nuclear reactors to power a Moon or Mars base through the long lunar night and the dim Martian winter, when solar power is not enough. NASA's KRUSTY test demonstrated the underlying Kilopower reactor technology on the ground.
