Astronaut Ron Garan took this image during the spacewalk conducted on Tues., July 12, 2011. It shows the International Space Station with Space Shuttle Atlantis docked on the right and a Russian Soyuz on the far left. In the foreground is the Alpha Magnetic Spectrometer (AMS) experiment installed during the STS-134 mission. AMS is a state-of-the-art particle physics detector designed to use the unique environment of space to advance knowledge of the universe and lead to the understanding of the universe's origin by searching for antimatter and dark matter, and measuring cosmic rays.

Besides the shuttle, there are currently two Soyuz and two Progress vehicles docked. The vehicle nose-down in this photo is Soyuz TMA-21 which brought three Expedition 28 crew members to the ISS. It will depart in September. At the extreme left of the station, you can see a solar panel and the tail end of Progress M-11M (Progress 43 to NASA).
