The Alpha Magnetic Spectrometer (AMS), on the International Space Station since May 2011,  has acquired the largest number of particles ever measured in space by a single experiment, performing the most precise measurement of galactic cosmic rays (GCR) to-date.  A series of very complicated EVAs (Extra Vehicular Activities a.k.a. "spacewalks") extended the lifetime of the instrument allowing data taking for the entire lifetime of the space station.

The primary goals of AMS are the study of Dark Matter, antimatter, and cosmic rays. The detailed time variation of multiple particle species of GCR fluxes, measured during solar cycle 24, will be presented together with results on short term solar activity, including Forbush decreases (FDs) and solar energetic particles (SEPs). These results provide an invaluable resource for understanding the space radiation environment for future manned missions to the Moon and Mars, and for improving space weather forecasting capabilities.
