Final STS-131 Spacewalk Complete

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.
