Workers packed the special suits aboard Discovery at Launch Pad 39A at NASA’s Kennedy Space Center in Florida as part of the continuing preparations for Monday’s liftoff. The spacewalking suits are the familiar white versions that carry an astronaut’s power and life support systems. In that sense, each spacesuit is basically a small spacecraft for an astronaut outside the safety of the shuttle or the International Space Station. Mission Specialists Alvin Drew and Tim Kopra will don the suits for two spacewalks on the outside of the station. Spacewalking suits are considerably stronger than the orange partial pressure suits the whole crew wears for launch and landing.
Technicians also are continuing closeout work today on Discovery’s aft compartment and preparations are under way to pressurize the main propulsion systems.
The STS-133 crew meets with its lead flight directors today at NASA’s Johnson Space Center in Houston and will conduct a conference with the Expedition 25 crew on board the space station. Discovery’s six-person crew will fly to Kennedy on Thursday afternoon for the countdown and launch Monday at 4:40 pm. EDT.
