S83-35782 (18 June 1983) --- An Orbital Maneuvering System (OMS) engine firing caused this bright glow at the aft end of the Earth-orbiting space shuttle Challenger on June 18, 1983. Also visible in the 70mm exposure are parts of the Shuttle Pallet Satellite (SPAS-01). The experiment package for NASA's Office of Space and Terrestrial Applications (OSTA-2), the protective cradles for the Indonesian Palapa-B and Telesat Canada Anik C2 satellites, some getaway special (GAS) canisters and the Canadian-built Remote Manipulator System (RMS). The firing took place less than an hour after deployment of Anik. Photo credit: NASA
