The Alpha Magnetic Spectrometer was photographed during a spacewalk in January 2017. NASA astronauts Shane Kimbrough and Peggy Whitson successfully installed three new adapter plates and hooked up electrical connections for three of the six new lithium-ion batteries on the International Space Station. They also accomplished several get-ahead tasks, including a photo survey of the Alpha Magnetic Spectrometer.

KENNEDY SPACE CENTER, FLA. - An employee at the Space Station Processing Facility monitors engineering certification testing of the Alpha Magnetic spectrometer (AMS). The AMS is a superconducting magnet that will be used in an experiment from the International Space Station (ISS) to search for antimatter and dark matter in space. The testing is being performed to ensure that data flow from the external payload AMS and the internal AMS crew operation post can be successfully routed through the ISS systems.

STS091-367-033 (2-12 June 1998) --- This photo of the Space Shuttle Discovery's aft section features the Alpha Magnetic Spectrometer (AMS), as seen from Russia's Mir space station, docked with Discovery at the time. AMS is the first large-magnet experiment ever placed in Earth orbit. The scientific goal of this high-energy physics experiment is to increase our understanding of the composition and origin of the universe. It is designed to search for and measure charged particles, including antimatter, outside Earth's atmosphere. The charge of such particles can be identified only by their trajectories in a magnetic field.
