Houston TX (SPX) Apr 14, 2010 The third STS-131 spacewalk ended at 8:38 a.m. EDT, a six-hour, 24-minute outing for Mission Specialists Rick Mastracchio and Clayton Anderson. The spacewalkers fell behind the timeline when an alignment issue delayed the stowage of the depleted Ammonia Tank Assembly on a carrier in space shuttle Discovery's cargo bay. Some planned tasks had to be deferred. Before wrapping up, the spacewalkers 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. This was the final STS-131 spacewalk, the 236th conducted by U.S. astronauts, and the sixth for both Mastracchio and Anderson. It was the 143rd in support of International Space Station assembly and maintenance, totaling 893 hours, 33 minutes. It was the 115th spacewalk based out of the space station, totaling 706 hours, 18 minutes. Mastracchio's six spacewalks total 38 hours, 30 minutes and Anderson's six spacewalks total 38 hours, 28 minutes. The pair now ranks 21st and 22nd on the list of cumulative spacewalk time. Final Spacewalk for STS-131 Completed, Cargo Transfers Continue Spacewalkers Rick Mastracchio and Clayton Anderson completed the third and final spacewalk of the STS-131 mission at 8:38 a.m. EDT. They finished the installation of a new ammonia tank for the International Space Station's cooling systems during the 6-hour, 24-minute excursion. The spacewalk was replanned because of some difficulties bolting down the new ammonia tank on Sunday. Mastracchio wore a suit with red stripes around the legs and Anderson wore an unmarked suit. Mission Specialist Dorothy Metcalf-Lindenburger coordinated the spacewalk from inside the complex. Transfer activities resumed inside the station. With about three-quarters of the science rack, equipment, food and supply moves complete, the shuttle and station crews are working to get all the items into their final locations.
