Week in Space Data, every Friday.
Aetherflux, operating under the legal name Cowboy Space Corp, is building a LEO constellation of solar-powered satellites that beam energy to ground receivers via infrared lasers.
ACTIVE(formerly Aetherflux) Aetherflux is building a constellation of solar-powered satellites in LEO that beam energy to ground receivers using infrared lasers, providing on-demand power anywhere on Earth.
Aetherflux is a space energy startup developing a constellation of satellites in low Earth orbit that collect solar energy and beam it to ground-based receivers using shortwave infrared lasers. Unlike GEO-based space solar concepts, their LEO approach enables smaller, less expensive satellites and more focused energy delivery. The system is designed to provide power on demand to remote locations, disaster zones, military forward operating bases, and off-grid installations where traditional power infrastructure is unavailable or impractical.
