Flight Evidence

Prove Once, Deploy Everywhere: Flight Evidence Is Becoming Space's New Currency

Four 17-kilogram satellites are quietly rewriting what counts as proof in this industry. Aerospace Corporation’s DiskSat mission, launched on a Rocket Lab Electron in December, has spent the months since descending toward very low Earth orbit (VLEO) at roughly 2 kilometers a month, while engineers commission Enpulsion electric-propulsion systems meant to hold the four vehicles below 300 kilometers once they get there, according to the mission’s flight log as reported by SpaceNews . It is a slow, unglamorous process. Power management, communications, attitude control, thermal design, dispensing and ground operations are all being worked out in real time, on orbit, under real conditions. That is the point. Nobody buys VLEO capability off a spec sheet anymore. They buy flight evidence: proof, generated in orbit, that it actually works.
