At 5:46 a.m. EDT, the Alpha Magnetic Spectrometer-2 (AMS) was installed successfully on the outside of the International Space Station's right side. Mission Specialists Andrew Feustel and Roberto Vittori used the space shuttle’s robotic arm to extract it from Endeavour's payload bay. They handed it off to the space station’s Canadarm2, and Pilot Greg Johnson and Mission Specialist Greg Chamitoff then used the robotic arm to install AMS on the starboard side of the station’s truss.
The AMS team will monitor the experiment 24 hours a day, gathering data for as long as the space station is in orbit. Using a large magnet to create a magnetic field that will bend the path of the charged cosmic particles already traveling through space, eight different instruments will provide information on those particles as they make their way through the magnet.
Armed with that information, hundreds of scientists from 16 countries are hoping to determine what composes the universe and how it began, as the AMS searches for clues on the origin of dark matter and the existence of antimatter and other unusual matter. AMS also could provide information about pulsars, blazers, gamma ray bursts and any number of other cosmic phenomena.
