China News Service, Beijing, December 10 (Reporter Sun Zifa) At 4:14 am on December 10th, Beijing time, China's "Gravitational Wave Storm High Energy Electromagnetic Correspondence All-Sky Monitor (GECAM)" 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 form of one arrow and two stars, and the satellite successfully entered the predetermined orbit.
The all-sky monitor for gravitational wave bursts high-energy electromagnetic counterparts was specially deployed by the Chinese Academy of Sciences (Phase II) pilot project. Its two small satellites adopt a conjugate orbit constellation layout, which will provide high-energy radiation for gravitational wave gamma bursts and fast radio bursts. , Special gamma bursts and magnetar bursts and other high-energy celestial explosion phenomena are monitored throughout the 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 the merger of double compact stars.
In addition, the all-sky monitor for gravitational wave storms high-energy electromagnetic counterparts will also detect solar flares, earth gamma flashes and earth electron beams and other solar-terrestrial space high-energy radiation phenomena, and provide scientific observation data for further study of their physical mechanisms.
As the first scientific satellite launched after the launch of the Beijing Huairou Comprehensive National Science Center Space Science Laboratory, the Chinese Academy of Sciences and the Beijing Municipal Government have jointly named the space science satellite for the all-sky monitor of the gravitational wave storm high-energy electromagnetic counterpart "Huairou No. 1".
At the same time, in order to promote scientific dissemination, the satellite is nicknamed "Jimu". Its two satellites, "little 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, quickly download and issue observation warnings, and guide Chinese and foreign scientists to use various telescopes to make follow-up observations.
The Chinese Academy of Sciences is responsible for the organization and implementation of the all-sky monitor for the gravitational wave storm high-energy electromagnetic counterpart. The National Space Science Center of the Chinese Academy of Sciences is responsible for the development and construction of the overall engineering and ground support system. The Institute of Microsatellite Innovation of the Chinese Academy of Sciences is responsible for the development of satellite systems. The Institute is the unit that proposes mission science goals and is responsible for the development and construction of satellite payloads and scientific application systems. The Institute of Aerospace Information Innovation of the Chinese Academy of Sciences is responsible for the ground reception of scientific data.
The project mission measurement and control system is in charge of 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 11th launch of the Long March 11 solid launch vehicle, which is also the Long March of China. The 355th space flight of a series of carrier rockets.
According to the Chinese Academy of Sciences, the space science strategic pilot science and technology project is an important part of the Chinese Academy of Sciences’ "first action" plan. As a landmark achievement of building a technological power, the first phase of the special project has been deployed and successfully launched "Wukong", "Mozi" and "Wise Eyes" Scientific satellites such as "Shijian 10".
At the end of August 2019, the first technical verification satellite of the second phase of the special project, the microgravity technology experimental satellite "Taiji-1", was successfully launched, marking the first step in China's space gravitational wave detection.
In addition to the "Taiji-1" and the successful launch of the "Jimu" double star, the second phase of the Chinese Academy of Sciences Space Science Strategic Pilot Technology Special Project also deployed the Advanced Space-Based Solar Observatory (ASO-S) and the Einstein Probe (EP). ) And the solar wind-magnetospheric interaction panoramic imaging satellite (SMILE) and other space science satellite programs, which will be launched in the next 3 to 4 years, and are expected to achieve major original results in solar eruptive activities, time domain astronomy, and solar-terrestrial relations. .
