International Space Station – October 26, 2007 – Mission Specialists Scott Parazynski and Doug Wheelock wrapped up STS-120’s first spacewalk at 12:16 p.m. EDT. During the 6-hour, 14-minute excursion, the STS-120 and Expedition 16 crews successfully installed the Harmony module in a temporary location on the International Space Station and prepared the P6 truss for its relocation.
Parazynski and Wheelock removed and stowed the S-band Antenna Structural Assembly which is being returned to Earth on Discovery. Next, they secured a Payload and Data Grapple Fixture onto Harmony that could not be in place during launch, removed contamination covers and disconnected the power cables linking Harmony to Discovery.
When the spacewalkers’ preparations were complete, the station robotic arm operators removed Harmony from the payload bay and moved it to its position on Unity. Meanwhile, the spacewalkers prepared the P6 truss for its relocation.
The first spacewalk of STS-120 began at 6:02 a.m. Mission Specialist Paolo Nespoli coordinated spacewalk activities. Mission Specialists Stephanie Wilson and Clay Anderson and Expedition 16 Flight Engineer Dan Tani were at the controls of the station’s Canadian-built robotic arm. Four more spacewalks are scheduled during the STS-120 mission.
