A Day's Work
April 13, 2010
During the second spacewalk of the STS-131 mission, NASA astronauts Rick Mastracchio and Clayton Anderson (out of frame) unhooked and removed the depleted ammonia tank and installed a 1,700-pound replacement on the station's Starboard 1 truss. This was the second of three spacewalks in the coolant tank replacement process.
