CAPE CANAVERAL, Fla. - The wheels on space shuttle Endeavour make contact with Runway 15 at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida after 14 days in space, completing the 5.7-million-mile STS-130 mission to the International Space Station 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.
