Reaction Control System: 2,800 kg (6,100 lb). To reduce weight for ISS missions, most AFRSI insulation blankets on the upper surfaces of the orbiter were replaced with FRSI, lightweight crew seats were installed, the Extended Duration Mission provisions installed during OMDP-1 were removed, and numerous other smaller-scale changes aimed at reducing weight.Ĭrew Size: 8. Changes included installation of the final configuration ISS airlock and docking system. The work was shared between Palmdale and Kennedy. Updated avionics systems that included advanced general purpose computers, improved inertial measurement units and tactical air navigation systems, enhanced master events controllers and multiplexer-demultiplexers, a solid-state star tracker and improved nose wheel steering mechanisms.Īn improved version of the Auxiliary Power Units (APU's) that provided power to operate the Shuttle's hydraulic systems.Ġ2/15/82 Start structural assembly of Crew Module (as a structural spare)Ġ9/28/87 Start structural assembly of aft-fuselageġ2/22/87 Wings arrive at Palmdale from GrummanĠ5/07/91 Delivery to Kennedy Space CenterĮndeavour underwent its OMDP-1 overhaul from July 1996 to March 1997. Plumbing and electrical connections needed for Extended Duration Orbiter (EDO) modifications to allow up to 28-day missions. Endeavour's upgrades included:Ī 40-foot diameter drag chute that reduced the orbiter's rollout distance by 300 to 600 m. Most of this equipment would be incorporated into the other three orbiters during out-of-service major inspection and modification programs. Endeavour featured new hardware designed to improve and expand orbiter capabilities. These spares were later assembled into the orbiter Endeavour when the decision was made to build a replacement for Challenger. This contract was valued at $389 million and consisted of a spare aft-fuselage, mid-fuselage, forward fuselage halves, vertical tail and rudder, wings, elevons and a body flap. Span: 23.79 m (78.05 ft).Įmpty Weight was 68.574 kg at rollout and 78,000 kg with main engines installed.ĭuring the construction of Discovery and Atlantis, NASA opted to have the various contractors manufacture a set of 'structural spares' to facilitate the repair of an orbiter if one was damaged during an accident. Built as a replacement after the loss of the Challenger named after the first ship commanded by James Cook.ĪKA: OV-105.
