Station Spacewalks

November has certainly been spacewalk month! And it's not over yet.

Tuesday Nov. 20 4 a.m. to 10:30 a.m. CST, NASA TV will broadcast live coverage as ISS Commander Peggy Whitson and Dan Tani conduct a 6.5-hour spacewalk to hook up fluid, electrical and data lines for the relocated mating adapter and Harmony module.

Thanksgiving weekend, Saturday, Nov. 24 from 4 a.m. to 10:30 a.m. CST, NASA TV will broadcast live coverage of Whitson and Tani again. This spacewalk will complete the hook up of the mating adapter and Harmony module to the station and leave them ready for the docking of Atlantis and delivery of the Columbus module, set to launch Dec. 6.

The STS-122 flight in December will feature at least 3 spacewalks by the shuttle crew to install and hook up Columbus, replace some nitrogen tanks, deploy some new experiment packages, and return a failed control moment gyro (CMG). A fourth spacewalk is under discussion involving the solar alpha rotary joint (SARJ) that has filings floating inside it.
