The International Space Station Expedition 28 crew and the mission STS-135 Atlantis crew members pose for a photo

This NASA image taken on July 15, 2011 shows the International Space Station Expedition 28 crew and the mission STS-135 Atlantis astronauts as they form a circle for a portrait aboard the orbiting complex's Kibo laboratory of the Japan Aerospace Exploration Agency. The STS-135 crew consists of NASA astronauts Chris Ferguson, Doug Hurley, Sandy Magnus and Rex Walheim; the Expedition 28 crewmembers are JAXA astronaut Satoshi Furukawa, NASA astronauts Ron Garan and Mike Fossum, and Russian cosmonauts Andrey Borisenko, Alexander Samokutyaev and Sergei Volkov. Shuttle and station commanders Ferguson and Borisenko are in the 12 o'clock and six o'clock positions, respectively, on the circle. The U.S. flag pictured was flown on the first space shuttle mission, STS-1, and flew on this mission to be presented to the space station crew. It will remain onboard until the next crew launched from the U.S. will retrieve it for return to Earth. It will fly from Earth again, with the crew that launches from the U.S. on a journey of exploration beyond Earth orbit. Atlantis is at the Space Station for the final mission of NASA's space shuttle progra. UPI/NASA.
