context_page_description: STS-131 was a NASA Space Shuttle mission to the International Space Station. Space Shuttle Discovery launched on 5 April 2010 at 6:21 am from LC-39A, and landed at 9:08 am on 20 April 2010 on runway 33 at the Kennedy Space Center's Shuttle Landing Facility. The mission marked the longest flight for Space Shuttle Discovery.
  The primary payload was a Multi-Purpose Logistics Module loaded with supplies and equipment for the International Space Station. The mission also removed and replaced an ammonia tank assembly outside the station on the S1 truss. STS-131 furthermore carried several on-board payloads; this mission had the most payloads since STS-107. It is also the last shuttle mission with a crew of 7.
