AMS - Alpha Magnetic Spectrometer- is a payload that will be attached to the International Space Station with a unique task: search the unknown, look at dark matter, hunt antimatter, in brief discover the invisible: what we can't see but still represents 90% of the universe..

ESA is supporting this mission designed by Nobel laureate particle physicist Samuel Ting team with the participation of Institutes from 16 countries.

AMS, mostly made in Europe, assembled at CERN and tested at ESTEC, is planned to be sent to the ISS by the Space Shuttle early next year.
