![]() ![]() This time, astronaut Akers joined astronauts Thuot and Hieb. Satellite ground controllers were again able to stabilize the satellite, and a third spacewalk was conducted on May 13, 1992. The second spacewalk lasted 5 hours, 30 minutes. Again, the satellite began to wobble, and attempts to capture the satellite were abandoned after five unsuccessful tries. Satellite ground controllers were able to dampen the wobbling of the satellite, and a second spacewalk by astronauts Thuot and Hieb was conducted on May 11, 1992. After trying three times, additional attempts to capture the satellite were abandoned, and the spacewalk lasted 3 hours, 43 minutes. The primary task during this spacewalk was to have been the capture of the INTELSAT VI (F3) satellite, left in a useless orbit following a Commercial Titan III rocket failure on March 14, 1990.ĭuring the first spacewalk, the astronauts were unable to successfully attach a capture bar device to the satellite because the satellite began to wobble. In addition, astronauts attached a live rocket motor to an orbiting satellite for the first time.Īstronauts Thuot and Hieb conducted the first spacewalk of the mission on May 10, 1992. Also for the first time, three astronauts participated in a single spacewalk. For the first time, four spacewalks were conducted during a Space Shuttle mission. In addition to being the first flight of Endeavour, other important “firsts” occurred during the mission. Landing occurred during the 141st orbit.įor the first time in the Space Shuttle program, a drag chute was deployed during landing operations, although it was deployed after nosegear touchdown for test purposes. ![]() Mission duration was 8 days, 21 hours, 17 minutes, 38 seconds. PDT at Runway 22, Edwards Air Force Base, California. May 7 launch was delayed 34 minutes due to poor transoceanic abort site weather and a technical glitch with an orbiter master events controller. Launch was originally scheduled for but was bumped to to employ an earlier launch window with better daylight conditions in which to photograph orbiter behavior during its maiden launch. This operation did not impact Endeavour’s launch date. Following the Flight Readiness Firing of Endeavour’s three main engines on April 6, 1992, Shuttle managers decided to replace all three main engines due to irregularities detected in two high pressure main engine oxidizer turbopumps. Rollout to Launch Pad 39B – March 13, 1992 Rollover to Vehicle Assembly Building – March 7, 1992 Rollover to Orbiter Processing Facility (STS-49 Flow) – July 25, 1991 Tow to Vehicle Assembly Building (For Manufacturing) – May 8, 1991 ![]()
