Decayed: 13 October 1989
Mission: Built by the University of Surrey, UO-9 was UoSAT's first experimental satellite. It was a scientific and educational low-Earth orbit satellite containing many experiments and beacons but no amateur transponders. UO-9 was the first amateur satellite to carry an S-Band beacon. UoSAT 1 weight 52 kg and was box-shaped (740 x 420 x 420 mm) with a deployable gravity gradient boom. It was fully operational until it re-entered after nine years of service.
