STS-133Earth is reflected in the helmet visor of NASA astronaut Alvin Drew, STS-133 mission specialist, as he participates in the mission’s first session of extravehicular activity, as construction and maintenance continue on the International Space Station.

During the six-hour, 34-minute spacewalk, Drew and fellow NASA astronaut Steve Bowen installed the J612 power extension cable, move a failed ammonia pump module to the External Stowage Platform 2 on the Quest Airlock for return to Earth at a later date, installed a camera wedge on the right hand truss segment, installed extensions to the mobile transporter rail and exposed the Japanese ‘Message in a Bottle’ experiment to space.

STS-133Robonaut 2, better known as R2, will have to wait until May before being unpacked and tested as a potential astronaut helper. The space station residents are swamped with other chores during this week’s visit by Discovery, and Endeavour will be along in April, meaning the robot will stay put for a couple more months. “So far, space is great ? but I suspect it will be even better once I’m out of my box!” R2 said in a Twitter update. The world’s first humanoid in space cannot speak and certainly can’t write or post tweets.

As part of the survey and part of every mission’s activities, Discovery performed a back-flip for the rendezvous pitch manouevre.
