EVA 3

S124-E-007263 (8 June 2008) --- Astronaut Ron Garan, STS-124 mission specialist, participates in the mission's third scheduled session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 33-minute spacewalk, Garan and astronaut Mike Fossum (out of frame), mission specialist, exchanged a depleted Nitrogen Tank Assembly for a new one, removed thermal covers and launch locks from the Kibo laboratory, reinstalled a repaired television camera onto the space station's left P1 truss, and retrieved samples of a dust-like substance from the left Solar Alpha Rotary Joint for analysis by experts on the ground. The Columbus laboratory is visible in the foreground. The blackness of space and Earth's horizon provide the backdrop for the scene.
