In the Training Auditorium at NASA's Kennedy Space Center in Florida, Professor Sam Ting talks to employees about the Alpha Magnetic Spectrometer-2 (AMS). Ting is the particle physics detector's principal investigator at the Massachusetts Institute of Technology.
AMS 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-2 will fly to the station aboard space shuttle Endeavour's STS-134 mission targeted to launch Feb. 27, 2011. Photo credit: NASA/Jim Grossmann
