Mission Highlights

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