First flight of the Space Shuttle Endeavour: "The INTELSAT VI (F-3) satellite, stranded in an unusable orbit since its launch aboard a Titan vehicle in March 1990, was captured by crew members during an EVA (extravehicular activity) and equipped with a new perigee kick motor. The satellite was subsequently released into orbit and the new motor fired to put the spacecraft into a geosynchronous orbit for operational use...

The capture required three EVAs: a planned one by astronaut Pierre J. Thuot and Richard J. Hieb who were unable to attach a capture bar to the satellite from a position on the RMS; a second unscheduled but identical attempt the following day; and finally an unscheduled but successful hand capture by Pierre J. Thuot and fellow crewmen Richard J. Hieb and Thomas D. Akers as Commander Daniel C. Brandenstein delicately maneuvered the orbiter to within a few feet of the 4.5 ton communications satellite.

STS-49 Post Flight Press Conference Film:

from the STS-49 Mission Report:

"...The first flight of the Orbiter vehicle Endeavour (OV-105). In addition to the Endeavour vehicle, the flight vehicle consisted of an ET designated as ET-43 (LWT-36); three SSME's which were serial numbers 2030, 2015, and 2017 in positions I, 2, and 3, respectively; and two SRB'sdesignatedas BI-050....

The crew for this forty-seventh Space Shuttle flight was Daniel C. Brandenstein, Capt., USN, Commander; Kevin P. Chilton, Lt. Col., USAF, Pilot; Richard J. Hieb, Mission Specialist I; Bruce E. Melnick, Cmdr., USCG, Mission Specialist 2; Pierre J. Thuot, Cmdr., USN, Mission Specialist 3; Kathryn C. Thorton, Ph.D, Mission Specialist 4; and Thomas D. Akers, Lt. Col., USAF, Mission Specialist 5...

The STS-49 mission was launched from Kennedy Space Center launch complex 39B at 128:23:40:00.019 G.m.t. (7:40:00 p.m.e.d.t.) on May 7, 1992, on an inclination of 28.35degrees. The launch phase was satisfactory in all respects...

The first EVA was performed on flight day 4... Numerous attempts were made by the EV1 crew person to engage the INTELSAT satellite with the capture bar. The unsuccessful attempts resulted in the satellite being pushed away and wobbling... The second EVA, performed on flight day 5... Numerous capture attempts were again made,all of which were unsuccessful...

The third EVA, the first EVA ever performed with three EVA crew members, was performed on flight day 7 beginning with hatch opening at 134:21:06GMT (05:21:26MET), and lasting for 8 hours 32 minutes. Manual INTELSAT satellite capture was completed at 134:23:55GMT (06:00:15MET). The capture bar was attached and nominal satellite berthing activities began. The perigee kick motor was successfully attached and the satellite was deployed at 135:04:53GMT (06:05:13MET)...

The deorbit maneuver was performed at 137:19:55:14.9 GMT (08:20:15:14.9 MET). The maneuver was approximately 167.5 seconds in duration and resulted in a differential velocity of 314.3 ft/sec. Entry interface occurred at 137:20:27:03GMT. (08:20:47:03MET). Main landing gear touchdown occurred at Edwards Air Force Base.CA, on concrete runway 22 at 137:20:57:38GMT (08:21:17:38 MET) on May 16, 1992."
