On July 20, the shuttle undocked from the station for the final time and began preparations to return home. During their 13 days in space, the shuttle astronauts supplied the International Space Station with a new logistics module, tested tools, technologies, and techniques to refuel satellites in space, and collected old equipment from the space station.

Atlantis landed at Kennedy Space Center July 21, concluding NASA’s 30-year space shuttle program. In addition to the science the shuttle and earlier programs enabled, human space flight has given us a unique view of planet Earth, which includes the now iconic spectacle of Earth rising over the Moon taken during the first lunar landing on July 20, 1969, and the photographs taken from Atlantis during its last full day in space on July 20, 2011. In fact every flight is a mission to planet Earth, as described in the Earth Observatory’s tribute to the shuttle program.
