However, as a precaution, he returned to the Quest airlock while Anderson completed his final task. The hole was in the second of five layers and did not cause any leak or danger to Mastracchio. During the EVA, Mastracchio noted a hole on the thumb of his left glove. Pilot Charlie Hobaugh and station Flight Engineer Oleg Kotov moved two CETA cards, enabling future relocation of a solar array segment on mission STS-120. Mastracchio and Expedition 16 Flight Engineer Clay Anderson relocated the S-band antenna subassembly from P6 to P1, installed a new transponder on P1 and retrieved the P6 transponder. This was the 90th spacewalk devoted to station maintenance and construction. It will be returned to Earth on a future mission. 13: 6 hours, 28 minutes Williams and Mastracchio installed the 600- pound control moment gyroscope onto the Z1 segment of the station’s truss, storing the failed unit outside the station. They also retracted the forward heat-rejecting radiator from the P6 truss, which will be relocated to the end of the port truss during the STS 120 mission. Station flight controllers brought up the third computer later after determining an errant software command was the cause of the shutdown.įirst-time spacewalkers, Mission Specialists Rick Mastracchio and Dave Williams added the two-ton, 11-foot-long spacer, the Starboard 5 segment of the space station’s truss. The shutdown did not affect the spacewalk. The redundant system reacted as designed and the primary backup computer took over, and the third computer moved into the backup slot. Command and Control computer shut down unexpectedly at 2:52 p.m. On several occasions, Morgan and other astronauts answered questions from children from the Discovery Center in Boise, Idaho, the Challenger Center for Space Science Education in Alexandria, Va., and in Saskatchewan, Canada. The mission also included three educational events featuring teacher-turned-astronaut Morgan. During the spacewalks, astronauts installed the S5 truss, a gyroscope and external stowage platform 3. The stowage platform was attached to the P3 truss. Mission Specialists Tracy Caldwell and Morgan installed a 7,000-pound storage platform using only the station’s and shuttle’s robotic arms. Later, concern over Hurricane Dean’s movement toward Texas caused mission managers to end the mission one day early.Īstronauts participated in a first for the space station. The extension enabled a fourth spacewalk. Mission managers first extended the flight to 14 days after successfully drawing power from the station via the SSPTS. EDT while traveling 214 miles above the southern Pacific Ocean, northeast of Sydney, Australia. The shuttle and space station docked at 2:02 p.m. All members of the team believed that leaving the damaged tile “as is” did not pose a risk to the crew during re entry. After extensive engineering analyses and tests over several days, the mission management team decided not to direct a repair of the shuttle’s damaged tile before landing. The photography showed a 3-inch-round ding on the starboard underside and in-depth analysis showed damage occurred through the tile to the internal framework. 10, Commander Scott Kelly also performed a backflip with the orbiter so the International Space Station crew could take digital photos of the orbiter’s underside, checking the tiles for damage. They used the vehicle’s robotic arm and orbiter boom sensor system. 9, before docking on the space station, the crew took a close look at the heat shielding on Endeavour’s wing leading edges.
