Mission Highlights:
Canadian communications satellite TELESAT-H (ANIK), attached to Payload Assist Module-D (PAM-D), deployed into geosynchronous orbit on flight day two. On third day, defense communications satellite SYNCOM IV-I (also known as LEASAT-1) deployed. Allen and Gardner, wearing jet-propelled manned maneuvering units, retrieved two malfunctioning satellites: PALAPA-B2 and WESTAR-VI, both deployed on Mission 41-B. Fisher operated remote manipulator system, grappling satellites and depositing them in payload bay. Middeck payloads: Diffusive Mixing of Organic Solutions (DMOS), and Radiation Monitoring Equipment (RME).
