Two satellites for the detection of gravitational waves are launched by a Long March-11 carrier rocket from the Xichang Satellite Launch Centre in southwest China's Sichuan Province on 10 December 2020 at 4:14 BJT. Both satellites are for the detection of gravitational waves, composing the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission. The GECAM satellites will be used to monitor high-energy celestial phenomena such as gravitational wave gamma-ray bursts, high-energy radiation of fast radio bursts, special gamma-ray bursts and magnetar bursts, and to study neutron stars, black holes and other compact objects and their merger processes.
