A Russian government-operated Proton-M rocket with Block DM-03 upper stage will launch the Spektr-RG space telescope setting out to enter a halo orbit around the Sun-Earth Lagrange Point 2. The Russian-German observatory-class mission will study the interplanetary magnetic field, galaxies and black holes via a complement of five telescopes covering a broad energy range from the far ultraviolet to the hard X-ray spectrum. The spacecraft hosts the eROSITA and ART-XC instrument that are expected to operate for 7.5 years to complete a four-year all-sky survey followed by 3.5 years of pointed observations.
