First

NASA astronauts Steve Bowen and Alvin Drew are shown performing the STS-133 mission's first spacewalk as construction and maintenance continue on the International Space Station. During the six-hour, 34-minute spacewalk, Bowen and Drew 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.
