![]() The loss was not unexpected because of the station’s skewed asymmetry as the 17.8 ton, bus-sized S3/S4 truss was being moved toward the S1 truss. The spacewalk was delayed for about an hour after the station temporarily lost attitude control when the station’s control moment gyroscopes went offline due to the mass of the new truss segment in the final stage of its attachment. Mission Specialists Jim Reilly and Danny Olivas focused on the final attachment of bolts, cables and connectors to begin the activation of the S3/S4 truss segment and ready it for deployment of its solar arrays. At a distance of 46 miles from the station, the shuttle robot arm and orbiter boom sensor system were used to inspect the thermal protection system on both wings and the orbiter’s nose cap. A flyaround provided a good look at the reconfigured spacecraft. Atlantis undocked from the station June 19, leaving behind 19 tons of food, water and equipment. solar array wings tracking the sun during orbit of the station. On June 18, the Russians were able to demonstrate the station’s ability to maintain attitude control, enabling the shuttle’s departure.Īctivation of the rotary joint provided use of four U.S. They repeated the modification on the last two channels. ![]() The shuttle’s propulsion provided backup.īy June 15, Yurchikhin and Kotov got two of three lanes in both computers running after bypassing with external cabling what appeared to be a faulty power switch. teams, troubleshooting and restoring computer capabilities. On June 9, Pilot Lee Archambault and Mission Specialists Patrick Forrester and Steve Swanson used the shuttle’s robotic arm and an extension boom-mounted sensor system to inspect the heat shield on Atlantis’ wing leading edges and nose cap.Ĭlay Anderson was transferred to the International Space Station as an official station crewmember of Expedition 15 and Flight Engineer Suni Williams swapped places to join the Atlantis crew.Īn issue surfaced during the mission with the Russian segment computers that provide backup attitude control and orbital altitude adjustments. On June 8, the crew used the robotic arm to take a closer look at an area of an insulation blanket on the port orbital maneuvering system pod that was seen to be pulled away from adjacent thermal tiles.
