Dark Matter Particle Explorer

Astronomy
  • A Chinese Academy of Sciences satellite, with Swiss and Italian collaboration, launched in 2015 December to detect high-energy particles for signs of dark matter in the Universe. From a Sun-synchronous orbit it measures the energy, direction, and charge of incoming gamma rays and cosmic rays, some of which might result from the collision and annihilation of particles of dark matter. DAMPE’s instruments detect electrons and photons with energies from 5 GeV to 10 TeV and cosmic rays from 100 GeV to 100 TeV.

  • A Chinese space mission to detect electrons and photons in the range of 5 GeV–10 TeV at a resolution of 1.5% at 100 GeV in order to identify possible dark matter signatures. The satellite was launched on 17 December 2015, from Jiuquan Satellite Launch Centre, China, into a Sun-synchronous orbit at 500 km altitude.
