On February 12, 2010 American astronauts Nicholas Patrick and Robert Behnken performed a 6 hours and 32 minutes EVA.
The new Tranquility module became a part of the International Space Station, giving the orbiting outpost a new utility room and gym with a grand window on the world. The spacewalkers prepped the module for removal from the shuttle payload bay and then worked to install umbilicals after it was attached to the station. Attachments: |
