STS-131 EVA 3 PLB Setup and ATA LMC Install

S131-E-009456 (13 April 2010) --- NASA astronauts Rick Mastracchio (right) and Clayton Anderson, both STS-131 mission specialists, participate in 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 Anderson 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.
