China launches science satellite duo
(10 Dec 2020) Rocket: Chang Zheng 11; Payload: two GECAM astronomy satellites; Date: 9 December 2020, 2014 UTC; Launch site: Xichang Satellite Launch Center, China. The satellites were deployed into 587 km x 605 km x 29.00 degrees orbits.
The Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (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.
In addition, they will also detect high-energy radiation phenomena in space, such as solar flares, Earth gamma flashes and Earth electron beams, providing observation data for scientists.
The GECAM project is carried out by the Chinese Academy of Sciences. The Chang Zheng-11 rocket is developed by the China Aerospace Science and Technology Corporation.
