Original Title: One Arrow, Double Star, China Successfully Launched “Jimu” Space Science Satellite
China News Service, Beijing, December 10 (Reporter Sun Zifa) At 4:14 am on December 10 Beijing time, the “Gravitational Wave Storm High-energy Electromagnetic Correspondence All-Sky Monitor ( GECAM) “of China nicknamed” Jimu “A space science satellite was successfully launched into space by the Long March 11 solid carrier rocket at the Xichang Satellite Launch Center in the shape of an arrow and two stars, and the satellite entered successfully in the predetermined orbit.

Its two small satellites adopt a conjugate orbit constellation design, which will provide high-energy radiation for fast radio and gravitational wave gamma-wave bursts. Special gamma-ray and magnetar bursts and other high-energy celestial explosion phenomena are monitored in the whole sky to promote the solution of the formation and evolution of compact celestial bodies such as black holes and neutron stars, as well as the mystery of compact double star merging. In addition, the whole-sky monitor for high-energy electromagnetic homologous gravitational wave storms will also detect solar flares, terrestrial gamma rays and terrestrial electron beams and other solar-terrestrial space high-energy radiation phenomena, and provide data from scientific observation for a more detailed study of its physical mechanisms.
As the first scientific satellite launched after the launch of the Beijing Huairou National Comprehensive Science Center Space Science Laboratory, the Chinese Academy of Sciences and the Beijing Municipal Government have jointly appointed the space science satellite to monitor the entire sky of the high-energy electromagnetic counterpart gravitational wave storm “Huairou No. 1”. At the same time, to promote scientific popularization, the satellite is nicknamed “Jimu”, whose two satellites, “small pole” and “small eye”, are distributed on both sides of the earth forming two “poles”. Observe the violent explosion phenomena of extreme celestial bodies such as black holes and neutron stars, download and issue observation warnings quickly, and guide Chinese and foreign scientists to use various telescopes for follow-up observations.

The National Center for Space Sciences of the Chinese Academy of Sciences is responsible for the development and construction of the general ground support and engineering system. The Microsatellite Innovation Institute of the Chinese Academy of Sciences is responsible for the development of satellite systems. The Institute is the unit that proposes the scientific objectives of the mission and is responsible for the development and construction of satellite payloads and scientific application systems. The Aerospace Information Innovation Institute of the Chinese Academy of Sciences is responsible for the terrestrial reception of scientific data.
The project’s mission measurement and control system is run by the Xi’an Satellite Measurement and Control Center. The launch vehicle used for this launch mission was developed and produced by the First Research Institute of China Aerospace Science and Technology Corporation (China Academy of Launch Vehicle Technology). This mission is the eleventh launch of the Long March 11 solid launch vehicle and also the Long March of China Space Flight 355 of a series of carrier rockets.
According to the Chinese Academy of Sciences, the space science science and technology strategic pilot project is an important part of the “first action” plan of the Chinese Academy of Sciences. As a historic achievement in creating a technological powerhouse, the first phase of the special project “Wukong”, “Mozi” and “Wise Eye” Scientific satellites such as “Shijian 10” has been successfully deployed and launched. At the end of August 2019, the first technical verification satellite of the second phase of the special project, the “Taiji-1” microgravity technology experimental satellite, was successfully launched, marking the first step in the detection of space gravitational waves. from China.
