After the arrival of the Alpha Magnetic Spectrometer, or AMS, at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, Professor Sam Ting, AMS Principal Investigator from the Massachusetts Institute of Technology speaks with the media while STS-134 Commander Mark Kelly, Mission Specialists Michael Fincke and Greg Chamitoff look on.

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/Kim Shiflett
