NEWS ROOM: - Come to the International Space Station, which was held yesterday the first extravehicular activity (EVA-1) provided for the mission of Space Shuttle Discovery STS-133 , the 154 is dedicated to the ISS.
EVA-1 began at 16:46 (eng) and lasted 6 hours and 34 minutes. The two protagonists were astronauts Alvin Drew, in his first EVA, and Steve Bowen, a veteran at its 6th "space walk".
The first task undertaken was to install an extension a power cable (J612), which goes from node 1 to the Quest Airlock Unity and provides backup power to the node 3 Tranquillity. The extension was necessary because of the upcoming installation of the PMM Permanent Multipurpose Module (MPLM Leonardo ex) that would make it impossible to access the cable.
Assisted by the station's robotic arm (SSRMS) the two EVA astronauts then installed a new pump for the ammonia the External Stowage Platform 2, outside the Quest airlock. The old pump (not working from 2010) will be recovered later. It 'was then installed a security system in case of need excretes ammonia remaining in the space (the pump).
Still, Bowen and Alvin have installed a wedge into the right side of the truss by removing a camera from the Express Logistics Carrier-4 to make room for subsequent installations.
Alvin Bowen and then added two extensions to the Mobile Transporter rails, so that it can move along the length of the truss and reach all relevant sites with the CETA (Crew Equipment Translation Aid).
The last activity was the opening and filling a metal cylinder "with the vacuum of space" as part of an initiative Space Agency Japanese JAXA called "Message in a Bottle." The cylinder will be returned to Earth and is exposed to the public.
