Landing:
November 16, 1984, 6:59:56 a.m. EST, Runway 15, Kennedy Space Center, Fla. Rollout distance: 9,461 feet Rollout time: 58 seconds. Landing Weight: 207,505 lbs.

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).

    "For a Few Dollars More" Bob Springer told the crew,"It's a tribute to the day's activities" Springer referred to the fact that originally one group of insurance companies had agreed to pay NASA $4.8 million to retrieve only the Palapa payload. But two months ago, another group of underwriters signed up for the Westar salvage and NASA said it would do both jobs for a total of $5.5 million. Chicago Tribune 11/15/84 CAPCOM: Bob Springer
