Spacecraft
Space Shuttle Discovery (OV-103)
Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, gathering more spaceflights than any other spacecraft to date. Discovery became the third operational orbiter to enter service, preceded by Columbia and Challenger. It embarked on its last mission, STS-133, on February 24, 2011 and touched down for the final time at Kennedy Space Center on March 9, having spent a cumulative total of almost a full year in space. Discovery performed both research and International Space Station (ISS) assembly missions. It also carried the Hubble Space Telescope into orbit. Discovery was the first operational shuttle to be retired, followed by Endeavour and then Atlantis.
- Destination: International Space Station
- Mission length: 15 days

About this launch
STS-131 was an ISS assembly flight with the primary payload being a loaded Multi-Purpose Logistics Module - Leonardo. The mission began on April 5th 2010 at 1021:22 UTC launching Commander Alan Poindexter, Pilot James Dutton, Mission Specialist 1 Richard Mastracchio, Mission Specialist 2 Dorothy M. Metcalf-Lindenburger, Mission Specialist 3 Stephanie Wilson, Mission Specialist 4 Naoko Yamazaki & Mission Specialist 5 Clayton Anderson to orbit. They docked with the ISS 2 days after launch. The mission was the final Space Shuttle launch with a seven person crew and was the longest flight for Discovery. STS-131 also marked the first time 4 women have been in space at once. During the mission 3 spacewalks were conducted to replace an ammonia tank and to retrieve a seed experiment from outside the Japanese laboratory. The mission concluded after 15 days & 2 hours on April 20th 2010 at 1308:35 UTC after 2 waved off landing opportunities on the 19th at the Kennedy Space Center.
