At 8:48 p.m. EST, space shuttle Discovery astronauts Steve Bowen and Alvin Drew will “campout” in the Quest airlock, preparing for Monday’s spacewalk. The airlock’s atmospheric pressure will be lowered to help purge nitrogen from Bowen and Drew’s bloodstreams, protecting them from “the bends” when they leave the airlock for the vacuum of space. The space station crew goes to sleep at 9:53 p.m. EST followed by Discovery’s crew at 10:23 p.m.

Discovery’s Final Flip

STS133-flipped-521155main 1874 946-710

This view of the nose, the forward underside and crew cabin of the space shuttle Discovery was provided by an Expedition 26 crew member during a survey of the approaching STS-133 vehicle prior to docking with the International Space Station. As part of the survey and part of every mission’s activities, Discovery performed a back-flip for the rendezvous pitch maneuver (RPM). The image was photographed with a digital still camera, using a 400mm lens at a distance of about 600 feet.

Cargo Transfers and Spacewalk Preps for Shuttle Crew

STS117inspace

Sun, 27 Feb 2011 06:58:16 -0600

The combined crews of space shuttle Discovery and the International Space Station awoke at 7:23 a.m. EST to the song “Java Jive” by Manhattan Transfer, played for shuttle Commander Steve Lindsey.

The crew will spend much of the day transferring supplies from Discovery to the space station and preparing for Monday’s spacewalk. They also will move the Orbiter Boom Sensor System from the side of Discovery’s cargo bay to the end of the shuttle robotic arm, clearing a pathway to transport the Permanent Multipurpose Module from Discovery to the station later in the mission.

Cargo Carrier Attached to Starboard Truss

A complex robotics operation involving multiple handoffs between the station and shuttle robotics arms successfully moved Express Logistics Carrier-4 (ELC-4) from space shuttle Discovery’s cargo bay to the Earth-facing side of the station’s right hand truss, or backbone. ELC-4 was attached to its permanent location on the starboard 3 truss Saturday at 10:12 p.m. EST. There it will store spare parts, including a heat rejecting radiator it carried to space for possible future use to cool the station.

Because the work kept the crew members awake later than scheduled, Mission Control advised them they can sleep in 30 minutes late on Sunday, awakening at 7:23 a.m.
