English: S83-35803 (22 June 1983) --- The Earth-orbiting space shuttle Challenger against the blackness of space was captured by a 70mm camera onboard the temporarily free-flying Shuttle Pallet Satellite (SPAS-01) during a busy Day 5 on the STS-7 mission. Visible in the cargo bay are the protective cradles for the now vacated Telesat Anik C2 and Palapa B communications satellites, the pallet for the NASA Office of Space and Terrestrial Applications (OSTA-2); the Remote Manipulator System (RMS) and the KU-Band antenna. The STS-7 astronaut crew with the RMS arm later retrieved the SPAS and returned it to a stowed position in the cargo bay for the return to Earth.
