The Alpha Magnetic Spectrometer (AMS-02) is a state-of-the-art particle physics detector 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 antimatter and dark matter while performing precision measurements of cosmic rays composition and flux. The AMS-02 observations will help answering fundamental questions, such as “What makes up the universe’s invisible mass?” or “What did happen to the primordial antimatter?”
