The Spektrum-Röntgen-Gamma (Spektr-RG / SRG) spacecraft will be carrying the German ‘extended ROentgen Survey with an Imaging Telescope Array’ (eROSITA) X-ray telescope and its Russian ART-XC partner instrument. A Proton rocket will carry the spacecraft from the Baikonur Cosmodrome towards its destination – the second Lagrange point of the Sun-Earth system, L2, which is 1.5 million kilometres from Earth. In orbit around this equilibrium point, eROSITA will embark upon the largest ever survey of the hot Universe.
