 The satellites are to be launched together on a CZ-11 rocket from China`s Xichang space center in December 2020.
 
 GECAM fast-tracked selection and development to take advantage of a new scientific opportunity, which Xiong Shaolin, an astrophysicist at CAS`s Institute of High Energy Physics in Beijing, and his colleagues identified a month after the U.S. Laser Interferometer Gravitational-Wave Observatory announced its historic detection of gravitational waves in February 2016 Nyckelord :  #Raket,  #Satellit,  #Sond,  RYMDREVYN : 07 - 2021 Senast ändrad: 20/07/2021 @ 17h18
