S117-E-07902 (18 June 2007) --- Astronaut Rick Sturckow, commander, pauses for a crewmate to take his picture during one of the rare moments of leisure during the STS-117 mission, following the crew's return to the Space Shuttle Atlantis. In chorus with the cosmonauts and astronauts on the International Space Station, Sturckow's crew earlier had successfully carried off four sessions of extravehicular activity to perform important work on the ISS. Crews aboard the space shuttle Atlantis and the space station bid farewell to one another and closed the hatches between their spacecraft at 5:51 p.m. on this day in preparation for the shuttle's departure the following morning at 9:42 a.m. The hatch closing wrapped up eight days of docked operations.
