Who: DAMPE Satellite
What: Launched by China
When: 17 December 2015
Why: To shed light on mysterious dark matter
China on 17 December 2015 launched the Dark Matter Particle Explorer (DAMPE) Satellite to shed light on mysterious dark matter.
It was the country’s first space telescope and launched on a Long March 2-D rocket from the Jiuquan Satellite Launch Center.
The purpose of the satellite is to search for smoking-gun signals of dark matter, invisible material that scientists say makes up most of the universe’s mass.
The satellite will be place in a sun-synchronous orbit at a height of 500 kilometers to observe the direction, energy and electric charge of high-energy particles in space.
The satellite was nicknamed “Wukong” after the Monkey King with penetrating eyes in the Chinese classical fiction Journey to the West.
