The DArk Matter Particle Explorer(DAMPE)is a space high-energy particle and γ-ray detector whose major scientific goals are the indirect detection of dark matter particles,the origin of cosmic rays and high-energy γ-ray astronomy.Since its successful launch in December 2015,the DAMPE has been operated smoothly in orbit for more than 8 years.The direct measurements of the boron-to-carbon and boron-to-oxygen flux ratios,and the proton+Helium spectrum up to 316 TeV have been obtained,revealing new spectral features with very high significances.The search results of y-ray spectral line and fractionally charged particles indicate a good potential of DAMPE for indirect dark matter detection and new physical discovery in space.The DAMPE measurements are expected to significantly advance our understanding of the fundamental problems in astroparticle physics.
