New ‘space mirror' satellite aims to bring sunlight to Earth even during the night

Tech Interesting Engineering
Reflect Orbital is testing Eärendil-1, a satellite equipped with a 60-foot reflective mirror, aiming to provide on-demand sunlight to specific ground zones.
What: The company intends to build a constellation of 50,000 mirrors by 2035 to sell sunlight for commercial, agricultural, and emergency applications in five-to-six kilometer zones.
Why it matters: This is a radical attempt to commoditize planetary resources, moving from static energy infrastructure to dynamic, satellite-based resource distribution.

Eärendil-1 is a demonstration 'space mirror' satellite with a highly reflective 60-foot thin-film mirror. Built by Reflect Orbital, the satellite will validate technologies that will eventually be used to sell sunlight on demand. The technology is designed to illuminate five- to six-kilometer zones for authorized commercial, agricultural, or emergency use. Reflect Orbital is aiming for a constellation of up to 50,000 orbiting mirrors by 2035.
