To detect dark matter and answer other fundamental questions about our universe, engineers and scientists from all over the world built the Alpha Magnetic Spectrometer ( AMS ), which NASA compares to the Hubble space telescope, and says could not be accommodated on a free flying satellite platform partly because of its power requirements and data bandwidth needs.

And frankly, it boils down to a moral issue . . . . Would you have a bilateral program with Stalin ? " This prohibition resulted in Chinese journalists being denied access to the launching of Space Shuttle Endeavour on the mission STS-134, that was carrying the Alpha Magnetic Spectrometer which was built in part by Chinese scientists.

Preliminary results from the presently operating Alpha Magnetic Spectrometer ( " AMS-02 " ) on board the International Space Station show that positrons in the cosmic rays arrive with no directionality, and with energies that range from 10 GeV to 250 GeV . In September, 2014, new results with almost twice as much data were presented in a talk at CERN and published in Physical Review Letters.
