The Spektr-RG astrophysical observatory was developed by Roscosmos with participation from Germany led by the German Aerospace Center (DLR), and is currently operating in a halo orbit around a special point in space called the L2 Lagrange point, some 1.5 million km from Earth. From here, its goal is to map the entire sky in X-rays and identify new X-ray sources, such as supermassive black holes, in the Universe.
