ESA astronaut Thomas Reiter, Expedition 13 Flight Engineer 2, works on a cooling line on the S1 truss of the International Space Station during a 5 hour 54 minute spacewalk on 3 August 2006.
Thomas’ spacewalk was part of his Astrolab mission, ESA’s first long-duration mission to the Station. He spent 166 days on the orbital outpost as part of Expeditions 13 and 14. After 171 days in space, Reiter returned to Earth on Space Shuttle STS-116.
