Space Shuttle Discovery Mission To International Space Station

IN SPACE - OCTOBER 28: In this handout provided by NASA, Astronaut Scott Parazynski, STS-120 mission specialist, participates in the second of five scheduled sessions of extravehicular activity (EVA) as construction continues on the International Space Station October 28, 2007. During the 6-hour, 33-minute spacewalk Parazynski and astronaut Daniel Tani (out of frame), Expedition 16 flight engineer, worked in tandem to disconnect cables from the P6 truss, allowing it to be removed from the Z1 truss. Tani also visually inspected the station's starboard Solar Alpha Rotary Joint (SARJ) and gathered samples of "shavings" he found under the joint's multi-layer insulation covers. Also the spacewalkers outfitted the Harmony module, mated the power and data grapple fixture and reconfigured connectors on the starboard 1 (S1) truss that will allow the radiator on S1 to be deployed from the ground later.
