May 7, 1992, 7:40 p.m. EDT. First flight of orbiter Endeavour. Launch originally scheduled for May 4 at 8:34 p.m. EDT, but was moved to May 7 for an earlier launch window opening at 7:O6 p.m. EDT which provided better lighting conditions for photographic documentation of vehicle behavior during the launch phase. Launch delayed 34 minutes due to TAL site weather conditions. Launch Weight: 256,597 lbs.

Inclination: 28.35 degrees
Orbits: 141
Duration: 8 days, 21 hours, 17 minutes, 38 seconds.

May 16, 1992, 6:57:38 p.m. EDT, Runway 22, EAFB, CA. Rollout distance 9,49O feet, no braking. First use of a drag chute during landing. Orbiter returned to KSC on May 30, 1992. Landing Weight: 201,649 lbs.

Mission Highlights:

INTELSAT VI (F-3) satellite, stranded in an unusable orbit since launch aboard a Titan vehicle in March 199O, was captured by crewmembers 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. An ASEM structure was erected in the cargo bay by the crew to serve as a platform to aid in the hand capture and subsequent attachment of the capture bar.

A planned EVA also was performed by astronauts Kathryn C. Thornton and Thomas D. Akers as part of the Assembly of Station by EVA Methods (ASEM) experiment to demonstrate and verify maintenance and assembly capabilities for Space Station Freedom. The ASEM space walk, originally scheduled for two successive days, was cut to one day because of the lengthy INTELSAT retrieval operation.

Other "payloads of opportunity" experiments conducted included: Commercial Protein Crystal Growth (CPCG), Ultraviolet Plume Imager (UVPI) and the Air Force Maui Optical Station (AMOS) investigation. Mission was extended two days to complete objectives.

The following records were set during the STS-49 mission:
* First EVA involving three astronauts.
* First and second longest EVA to date: 8 hours and 29
minutes and 7 hours and 45 minutes.
* First Shuttle mission to feature four EVAs.
* EVA time for a single Shuttle mission: 25 hours and
27 minutes, or 59:23 person hours.
* First Shuttle mission requiring three rendezvous with an
orbiting spacecraft. attached a live rocket motor to an
orbiting satellite.
* First use of a-drag chute during a Shuttle landing.
