With Commander Alan G. Poindexter and Pilot James P. Dutton Jr. at the controls, space shuttle Discovery descended to a smooth landing at Kennedy Space Center in Florida. The STS-131 crew members concluded their successful mission to the International Space Station when the shuttle touched down at 9:08 a.m. EDT.

Discovery arrived at the station April 7, delivering more than seven tons of equipment and supplies. During the 10-day stay, Mission Specialists Rick Mastracchio and Clayton Anderson conducted three spacewalks to install a 1,700-pound ammonia tank assembly on the station's exterior to replace a depleted predecessor. They also replaced a rate gyro assembly, retrieved a Japanese experiment and two debris shields.
