Catch First Spacewalk of STS-133 Today
Watch STS-133 Mission Specialists Alvin Drew and Steve Bowen perform the mission’s first spacewalk. The spacewalk is scheduled to begin at 10:18 a.m. but will likely begin early, as the crew is 45 minutes ahead of schedule. Watch on NASA TV or on the web:

During their 6 1/2-hour spacewalk, Drew and Bowen will install a power extension cable between the Unity and Tranquility nodes to provide a contingency power source. They will then move a failed ammonia pump module that was replaced in August 2010 from an attachment bracket to a stowage platform adjacent to the Quest airlock. The pump will be returned to Earth at a later date. Drew and Bowen will also install hardware under a camera on the truss that will tilt the camera to provide clearance for a spare part to be installed on a future mission and replace a guide for the rail cart system used for moving cargo along the truss. The final task will be to “fill” a special bottle with space for a Japanese education payload. The bottle will be part of a museum exhibit for public viewing.

Drew and Bowen will perform their second spacewalk on Wednesday, March, 2 beginning at 9:18 a.m.
