"NASA's 30-year Space Transportation System (STS) program came to an end on 21st July 2011. The Space Shuttle fleet delivered the Hubble Space Telescope, the International Space Station, and dozens of satellites, space probes, crew and supplies. Two Shuttles were lost: Challenger in 1986 and Columbia in 2003. The touchdown of Atlantis at Kennedy Space Center marked the end of an era, after 135 missions. This video shows all of them in chronological order. http://www.nature.com/spaceshuttle"
