Space shuttle Discovery roared into space on April 5 on mission STS-131 to the International Space Station.
Commanded by Alan Poindexter, the STS-131 crew also included James P. Dutton Jr., who served as the pilot; mission specialists Rick Mastracchio, Clayton Anderson, Dorothy Metcalf-Lindenburger, Stephanie Wilson and Japan Aerospace Exploration Agency astronaut Naoko Yamazaki.
Discovery delivered a multi-purpose logistics module filled with science racks that were transferred to laboratories on the International Space Station.
The mission featured three spacewalks performed by Mastracchio and Anderson. They replaced an ammonia tank assembly, retrieved a Japanese experiment from the station’s exterior and swapped a “rate gyro assembly” on the S0 element of the station’s truss.
STS-131 was the 33rd shuttle mission to the station.
