CAPE CANAVERAL, Fla. - Space shuttle Discovery nears touchdown on Runway 33 at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. Landing was at 9:08 a.m. EDT, completing the 15-day STS-131 mission to the International Space Station. Main gear touchdown was at 9:08:35 a.m. EDT followed by nose gear touchdown at 9:08:47 a.m. and wheelstop at 9:09:33 a.m. Aboard are Commander Alan Poindexter; Pilot James P. Dutton Jr.; and Mission Specialists Rick Mastracchio, Clayton Anderson, Dorothy Metcalf-Lindenburger, Stephanie Wilson and Naoko Yamazaki of the Japan Aerospace Exploration Agency. The seven-member STS-131 crew carried the multi-purpose logistics module Leonardo, filled with supplies, a new crew sleeping quarters and science racks that were transferred to the International Space Station's laboratories. The crew also switched out a gyroscope on the station’s truss, installed a spare ammonia storage tank and retrieved a Japanese experiment from the station’s exterior. STS-131 is the 33rd shuttle mission to the station and the 131st shuttle mission overall.

CAPE CANAVERAL, Fla. - The cloudy weather over Florida's spaceport relented, providing a beautiful night for the return of space shuttle Endeavour. Endeavour's landing on Runway 15 at NASA Kennedy Space Center's Shuttle Landing Facility followed 14 days in space, completing the 5.7-million-mile STS-130 mission on orbit 217. Main gear touchdown was at 10:20:31 p.m. EST followed by nose gear touchdown at 10:20:39 p.m. and wheels stop at 10:22:10 p.m. It was the 23rd night landing in shuttle history and the 17th at Kennedy. Aboard are Commander George Zamka; Pilot Terry Virts; and Mission Specialists Robert Behnken, Nicholas Patrick, Kathryn Hire and Stephen Robinson. During Endeavour's STS-130 mission, astronauts installed the Tranquility node, a module that provides additional room for crew members and many of the station's life support and environmental control systems. Attached to Tranquility is a cupola with seven windows that provide a panoramic view of Earth, celestial objects and visiting spacecraft. The module was built in Turin, Italy, by Thales Alenia Space for the European Space Agency. The orbiting laboratory is approximately 90 percent complete now in terms of mass. STS-130 was the 24th flight for Endeavour, the 32nd shuttle mission devoted to ISS assembly and maintenance, and the 130th shuttle mission to date.

CAPE CANAVERAL, Fla. - Touchdown is apparent by the streams of smoke trailing space shuttle Endeavour as its main landing gear tires contact Runway 15 at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida. After 14 days in space, Endeavour's 5.7-million-mile STS-130 mission is completed on orbit 217. Main gear touchdown was at 10:20:31 p.m. EST followed by nose gear touchdown at 10:20:39 p.m. and wheels stop at 10:22:10 p.m. It was the 23rd night landing in shuttle history and the 17th at Kennedy.
