In Space

NASA

The Alpha Magnetic Spectrometer-2 (AMS) is seen in space shuttle Endeavour's payload bay after the shuttle reached orbit. Shortly after this image was taken, the AMS was moved from the payload bay to the station's starboard truss on May 19, 2011 (Flight Day 4).

AMS in the Clean Room

AMS-02 Collaboration

The Alpha Magnetic Spectrometer, a $2 billion experiment to hunt for cosmic rays in space, stands in the clean room at the European physics lab CERN before it is shipped to NASA to be launched on a space shuttle.

Technicians examine the $2 billion Alpha Magnetic Spectrometer instrument in a work stand ahead of its planned launch on NASA's space shuttle Endeavour. The AMS instrument will search for cosmic rays from the International Space Station.

Movin' Out

U.S. Mission Geneva/Eric Bridiers

Back on August 25, 2010, workers loaded the AMS (inside the metal box at right) aboard a giant U.S. Air Force Galaxy jet for a flight from Geneva International Airport to the Kennedy Space Center in Florida.
