NASA astronauts Rick Mastracchio (left) and Clayton Anderson, both STS-131 mission specialists, participate in the mission's second session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the seven-hour, 26-minute spacewalk, Mastracchio and Anderson unhooked and removed the depleted ammonia tank and installed a 1,700-pound ammonia tank on the station's Starboard 1 truss, completing the second of a three-spacewalk coolant tank replacement process.
