STS-135 Wheels Stop Event

NASA employees and contractors crowd together to get a glimpse of space shuttle Atlantis (STS-135) as it rolls toward the Orbiter Processing Facility (OPF) at a wheels stop event, Thursday, July 21, 2011, at NASA's Kennedy Space Center in Cape Canaveral, Fla. Atlantis returned to Kennedy early Thursday following a 13-day mission to the International Space Station (ISS) and marking the end of the 30-year Space Shuttle Program. Overall, Atlantis spent 307 days in space and traveled nearly 126 million miles during its 33 flights. Atlantis, the fourth orbiter built, launched on its first mission on Oct. 3, 1985.
