On August 07, 2010 American astronauts completed the first of two planned spacewalks to fix a failed cooling pump on the International Space Station (ISS).
It was conducted by Expedition 24 flight engineers Tracy Caldwell Dyson and Douglas Wheelock.
The spacewalk, which lasted for eight hours and three minutes, became the longest ever conducted from the ISS and the sixth longest in human spaceflight history.
One of two cooling systems serving the ISS broke down late on July 31, and the crew had shut down several pieces of equipment, including two of the station's four gyroscopes, to cut the heat generated on board. Attachments: |
