CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, STS-134 Mission Specialists Michael Fincke, Andrew Fuestel, Pilot Gregory C. Johnson, Commander Mark Kelly and Mission Specialist Greg Chamitoff (in blue flight suits) join the Air Force C-5M flight crew that delivered the Alpha Magnetic Spectrometer, or AMS, to the Shuttle Landing Facility, in a group photo opportunity. AMS, a state-of-the-art particle physics detector, is designed to operate as an external module on the International Space Station. It will use the unique environment of space to study the universe and its origin by searching for dark matter. AMS will fly to the International Space Station aboard space shuttle Endeavour's STS-134 mission, targeted to launch Feb. 26, 2011. Photo credit: NASA/Jack Pfaller
