Mission Summary:

Sally K. Ride became the first American woman to fly in space. Two communications satellites were deployed. The ANIK C-2 was deployed for TELESAT Canada and the PALAPA-B1 was deployed for the government of Indonesia. Both satellites were attached to PAM-D solid rocket motors.

Seven GAS canisters were flown, one of which included a study on the effects of microgravity on an ant colony. Ten experiments were mounted on the Shuttle Pallet Satellite (SPAS-01), including the testing of metal alloy formation and use of a remote sensing scanner.

Challenger’s remote manipulator arm grasped SPAS-01 while the Shuttle’s control rockets fired to test the movement of the pallet while attached to the arm.

Experiments on space sickness were performed. Other payloads included Office of Space and Terrestrial Applications-2 (OSTA-2), Continuous Flow Electrophoresis System (CFES), Monodisperse Latex Reactor (MLR) and one SSIP experiment.
