Context : Spektr-RG is a Russian–German high-energy astrophysics space observatory launched recently. It follows on from the Spektr-R satellite telescope launched in 2011. About Spektr- RG: The Spektrum-Röntgen-Gamma mission , also known as Spektr-RG , is a joint project between the Russian space agency, Roscosmos, and the German space agency, DLR . Position : Spektr-RG will be placed in a stable orbit in space called a Lagrange point (specifically, L2) , where the gravitational forces of two large objects — in this case, the sun and the Earth — balance each other out. This location will allow Spektr-RG to perform its observations while using a minimal amount of fuel. Objectives : The spacecraft is expected to detect 100,000 galaxy clusters, 3 million supermassive black holes, tens of thousands of star-forming galaxies, the presence of plasma (superheated gas) and many more types of obje...
