The Dark Matter Particle Explorer, or DAMPE, also known as Wukong (Chinese: 悟空), is a Chinese Academy of Sciences (CAS) satellite which launched on 17 December 2015.[4] 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.[4] It is China's first 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.[4][6] It was designed to look for the indirect decay signal of a hypothetical dark matter candidate called weakly interacting massive particles (WIMPs).[7]
The project is the result of a collaboration among research institutions and universities in Italy, Switzerland and China under the leadership of the Purple Mountain Observatory (PMO) of the Chinese Academy of Sciences (CAS).
