Mission highlights

TELESAT-l (ANIK C-1) communications satellite deployed, attached to Payload Assist Module (PAM-D) motor. SYNCOM
Syncom

Syncom started as a 1961 NASA program for active geosynchronous communication satellites, all of which were developed and manufactured by Boeing Satellite Systems....
 IV-3 (also known as LEASAT-3) deployed, but the spacecraft sequencer failed to initiate antenna deployment, spin-up, and ignite the perigee kick motor. Mission extended two days to make certain sequencer start lever in proper position. Griggs and Hoffman performed space walk to attach Flyswatter devices to remote manipulator system. Seddon engaged LEASAT lever using remote manipulator system but post deployment sequence did not begin. Other payloads: Continuous Flow Electrophoresis System (CFES) III, flying for sixth time; two Shuttle Student Involvement Program (SSIP) experiments; American Flight Echocardiograph (AFE); two Getaway Specials; Phase Partitioning Experiments (PPE); astronomy Photography verification test; medical experiments and "toys in space," an informal study of the behavior of simple toys in weightless environment, with results to be made available to school students. Extensive brake damage and blown tire during landing prompted landing of future flights at Edwards Air Force Base until implementation of nose wheel steering.
