NASA STS-133 Report #12 5:30 a.m. Wednesdsay, March 2, 2011

Mission Control Center, Houston, Texas

HOUSTON – After a campout in the International Space Station’s Quest airlock, Mission Specialists Steve Bowen and Alvin Drew will suit up for the second spacewalk of the STS-133 mission. The spacewalk is scheduled to start at 9:18 a.m. CST.

With a call from Mission Control Houston, space shuttle Discovery’s crew was awakened at 4:23 a.m. by the song, “The Speed of Sound” by Coldplay. It was played for Pilot Eric Boe.

Mission Specialist Nicole Stott will choreograph the spacewalk as the intravechicular officer while Mission Specialist Mike Barratt and station Commander Scott Kelly operate the Canadarm2 from the robotic workstation in the station’s cupola.

The spacewalkers will perform several tasks during their excursion, including venting ammonia from the failed pump module they moved to a storage location on Monday’s spacewalk. They’ll also remove a lightweight adapter plate previously used to attach experiments to the exterior of the Columbus laboratory and remove insulation from the Tranquility node and the newly installed Express Logistics Carrier 4.

The spacewalkers also will install a light on one of the crew equipment and translation aid – or CETA – carts, install a light, pan and tilt assembly on Dextre, the space station’s Special Purpose Dexterous Manipulator, and troubleshoot a loose radiator grapple fixture stowage beam, which would be used if a radiator ever needed to be replaced.

The spacewalk is expected to last 6 hours and 30 minutes.

Meanwhile crew members inside the complex will continue transferring more cargo from Discovery and loading trash into the Japanese Kounotouri2 H-II Transfer Vehicle for eventual disposal.

The next status report will be issued at the end of the crew’s day or earlier if necessary. The crew’s sleep period is scheduled to begin just before 8 p.m.
