NASA STS-133 Report #20 Sunday, March 6, 2011 – 2:30 a.m. CST

Mission Control Center, Houston, Texas

HOUSTON – With all the work that they’ve accomplished over their past several days in space, the space shuttle Discovery crew members have just a few more tasks left to complete before they say goodbye to their International Space Station colleagues.

The crews’ last day together started at 2:23 a.m., with the wakeup song, “Spaceship Superstar” by Prism. It was chosen for all Discovery crew members by the team of flight controllers who have been supporting them overnight throughout the mission.

The space shuttle and space station crews are scheduled to say their goodbyes and close hatches on their respective vehicles at 2:33 p.m. To prepare for that, Mission Specialists Alvin Drew and Steve Bowen will move the suits and tools they used during the mission’s two spacewalks back over to Discovery.

Commander Steve Lindsey, Pilot Eric Boe and Mission Specialists Nicole Stott and Michael Barratt will finish up the last of the transfer work for the mission, bringing the few remaining items on the transfer list over to Discovery for return to Earth. Bowen and Barratt will also perform a checkout of some of the systems and tools that will be used during Discovery’s undocking from the station on Monday.

Meanwhile, station Commander Scott Kelly will wrap up the repair work he started yesterday on the station’s Oxygen Generation System, and Flight Engineer Cady Coleman will work on an experiment that measures how astronauts’ heights change during visits to space.

Most of that will take place in the crew’s morning, leaving them several hours of off-duty time in their afternoon to enjoy before they say their farewells.

The next status report will be issued at the end of the crew’s day or early if warranted. Discovery’s crew is scheduled to begin its sleep period at 6:23 p.m.
