A first on-orbit fuel depot has been deployed. Orbit Fab’s 35kg Tanker-001 Tenzing was one of the many spacecraft aboard Transporter-2. Deployed by Spaceflight’s Sherpa tug, the mini-tanker carries high-test peroxide (HTP), a green alternative to hydrazine, long-used for orbital station-keeping. Orbit Fab and its first orbital refueling spacecraft are at the heart of a small web of space startups that will test the long imagined promise of on-orbit satellite refueling.
