CAPE CANAVERAL, Fla. -- Before the arrival of the Alpha Magnetic Spectrometer, or AMS, to the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, European Space Agency Director of Human Spaceflight, Simonetta Di Pippo addresses the media. 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
