The Dark Matter Particle Explorer, or DAMPE, is a Chinese Academy of Sciences (CAS) satellite which was launched on 17 December 2015 at 00:12 UTC. The satellite was launched on a Long March 2D rocket from Launch Pad 603 at the LC-43 complex, also known as the South Launch Site, at the Jiuquan Satellite Launch Center. It is China's first ever space observatory.
DAMPE is a space telescope used for the detection of high energy gamma rays, electrons and cosmic ray ions, to aid in the search for dark matter. The project is the result of a collaboration among universities in Italy, Switzerland, and the Chinese Academy of Sciences.
It is nicknamed Wukong (Chinese: 悟空) after the Monkey King, who is the hero in the classic Chinese tale Journey to the West. Literally, "wu"(悟) means comprehension or understanding and "kong"（空）means void, so this name could also be understood as "understanding the void", relating to the undiscovered nature of dark matter.
DAMPE has been realized through a collaboration between China, Italy and Switzerland. The institutes that have been part of the collaboration are: IHEP (Institute of High Energy Physics), CAS (Chinese Academy of Sciences), Beijing, China; IMO (Institute of Modern Physics), CAS (Chinese Academy of Sciences), Lanzhou, China; NSSC (National Space Science Center), CAS (Chinese Academy of Sciences), Beijing, China; PMO (Purple Mountain Observatory), CAS (Chinese Academy of Sciences), Nanjing, China; USTC (University of Science and Technology of China), Hefei, China; INFN (Istituto Nazionale di Fisica Nucleare) and University of Perugia, Italy; INFN (Istituto Nazionale di Fisica Nucleare) and University of Bari, Italy; INFN (Istituto Nazionale di Fisica Nucleare) and University of Lecce, Italy; DPNC (Département de physique nucléaire et corpusculaire), University of Geneva, Switzerland.
The scientific objectives of the mission are:
- the search and study of dark matter particles by conducting high-resolution observations of high-energy electrons and gamma rays.
- the study of the origin of cosmic rays by observing high energy electrons and heavy nuclei in the TeV energy range.
- the study of the propagation and acceleration mechanisms of cosmic rays through the observation of high-energy gamma rays.
