The study of dark matter is the current active subject of science research. There are three kinds of methods to detect dark matter particles which are direct detection, indirect detection and collider detection. The indirect detection of dark matter (DM) particles search the signals produced by DM annihilation or decay which are all kinds of excesses in the energy spectrum of CRs. The dark matter particle explorer (DAMPE) has already launched to space at December 27, 2015. It is the first science satellite in china and it has three advantages: large energy range, high energy revolution and strong background distinction. The mean scientific goals are dark matter indirect detection, cosmic ray physics and gamma ray astronomy. In this paper, we will introduce the structure of DAMPE, the advantage of DAMPE and the scientific goals of DAMPE.
