ISS023-E-022227 (13 April 2010) --- NASA astronaut Rick Mastracchio, STS-131 mission specialist, works near the Quest airlock during the mission's third and final session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 24-minute spacewalk, Mastracchio and astronaut Clayton Anderson (out of frame), mission specialist, hooked up fluid lines of the new 1,700-pound tank, retrieved some micrometeoroid shields from the Quest airlock’s exterior, relocated a portable foot restraint and prepared cables on the Zenith 1 truss for a spare Space to Ground Ku-Band antenna, two chores required before space shuttle Atlantis' STS-132/ULF-4 mission in May.
