S135-E-007483 (12 July 2011) --- NASA astronaut Doug Hurley temporarily visits the middeck of the space shuttle Atlantis during spacewalk day on the International Space Station, July 12, 2011. The STS-135 pilot did not go outside the orbiting joint complex of shuttle and station, but he remained in the shirt-sleeved environment to provide important support to the two spacewalkers.
