During the 6-hour, 33-minute spacewalk Tani and astronaut Scott Parazynski (out of frame), STS-120 mission specialist, 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.
