At a post-landing news conference, Assistant Administrator for NASA Public Affairs David Mould (left) introduces NASA Associate Administrator for Space Operations William Gerstenmaier and Shuttle Launch Director Mike Leinbach. They concurred they were happy with the performance of space shuttle Atlantis on the STS-122 mission and looking forward to the next mission, STS-123 in March. After a round trip of nearly 5.3 million miles, space shuttle Atlantis and crew returned to Earth with a landing at 9:07 a.m. EST. The shuttle landed on orbit 202 to complete the 13-day STS-122 mission. Main gear touchdown was 9:07:10 a.m. Nose gear touchdown was 9:07:20 a.m. Wheel stop was at 9:08:08 a.m. Mission elapsed time was 12 days, 18 hours, 21 minutes and 44 seconds. During the mission, Atlantis' crew installed the new Columbus laboratory, leaving a larger space station and one with increased science capabilities. The Columbus Research Module adds nearly 1,000 cubic feet of habitable volume and affords room for 10 experiment racks, each an independent science lab. Photo credit: NASA/Jim Grossmann
