EVA-32 Completed on ISS

Two American astronauts worked outside the International Space Station last week, performing maintenance and preparations for upcoming missions to the station.

Astronauts Scott Kelly (commander of current Expedition 45) and Kjell Lundgren stayed on EVA-32 for a seven-hour session, completing many needed maintenance objectives. Firs, they uncovered a thermal protective cover from the Main Bus Switching Unit that had failed earlier in 2012 and was being stored outside the station on the main truss.  By removing the cover, they have prepared the switching unit for later being grappled by the robotic arm and then being moved into the station for delicate repair work. Next, they installed a thermal cover on the Alpha Magnetic Spectrometer experiment, which will extend the lifetime of the coolant pumps on the AMS.

One important item completed during the walk was the lubrication of the grapple end of the robotic arm. Following that, the pair of spacewalkers continued to move cables and wiring on the Node 1 port to the Node 2 port. This effort was in support of making changes to the station to allow for the future busy docking schedules for new spacecraft from SpaceX and Boeing, as well as the eventual use of the Orion spacecraft being developed by NASA.

On October 16, Kelly broke the record for the longest number of flight days in space for American astronauts. The previous record was held by astronaut Mike Fincke, at 382 days.
