|Fig. 1. AMS, far left, was installed by NASA on the International Space Station on 19 May 2011, where it is the only major physical science experiment. It will operate there for the station’s lifetime of approximately 20 years.

AMS-02 is a large particle detector by space standards and built using the concepts and technologies developed for experiments at particle accelerators but adapted to the extremely hostile environment of space. Measuring 5 × 4 × 3 m3, it weighs 7.5 tonnes. Reliability, performance and redundancy are the key features for the safe and successful operation of this instrument in space (CERN Courier July/August 2011 p18 and p23). See: AMS-02 provides a precise measure of cosmic rays
It’s important I think to see the context of particle reductionism in the proper light as we examine what goes on in LHC. Doing AMSII work on space station at the same time, we see from space those energies which help us to understand the naturalness of the work being done.
