Brokkr-1
A small cubesat AstroForge sent to low Earth orbit in 2023 to test a metal-refining process in space. Problems communicating with the satellite kept the refining test from running.
Why it matters
Refining metal in space is a step AstroForge's asteroid-mining plan depends on. Brokkr-1 was its first attempt to test that step, on a small satellite.
How the technology works
Brokkr-1 was a cubesat launched into low Earth orbit in 2023 carrying a refinery test payload. Problems communicating with the spacecraft kept AstroForge from running the refinery demonstration, according to SpaceNews.
