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.[5] 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.[5] 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 rays, to aid in the search for dark matter.[5][6] The project is the result of a collaboration among universities in Italy, Switzerland, and the Chinese Academy of Sciences.[7][8]
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 its name could also be understood as "understand the void", relates to the undiscovered dark matter.[9]
Objectives
The scientific objectives of the mission are: [3]
- the search and study of dark matter particles by conducting high-resolution observation of high-energy electrons and gamma rays.
- the study the origin of cosmic rays by observing the high energy electron and heavy nuclei above TeV.
- the study of the propagation and acceleration mechanism of cosmic rays by observing high-energy gamma rays.
