  The Alpha Magnetic Spectrometer (AMS) is a cosmic ray (CR) experiment that
will operate on the International Space Station for three years, measuring the
particle spectra in the rigidity range from 0.2 GV to 2 TV. The AMS-02 detector
will provide measurements with unprecedented statistics of the hadronic and
leptonic cosmic rays, allowing for a better study of the Earth magnetosphere
through the secondaries produced by CR interactions in the atmosphere; of the
solar system environment through the measurement of the solar modulation over a
long period; of the solar system neighborhood through the measurement of the
ratio between unstable isotopes and stable elements; of the interstellar medium
of our Galaxy through the ratio between secondary and primary isotopes and the
measurement of proton and helium spectra.
