Spektr-RG (Russian for Spectrum + Röntgen + Gamma; also called Spectrum-X-Gamma, SRG, SXG) is a Russian/German high-energy astrophysics space observatory planned to launch in June 2019. It will follow on from the Spektr-R satellite telescope launched in 2011.

Overview[edit]

The primary instrument of the mission is eROSITA, built by the Max Planck Institute for Extraterrestrial Physics (MPE) in Germany. It is designed to be used to conduct a 4-year X-ray survey, the first in a medium X-ray band up to 10 keV energies. This survey should detect many new clusters of galaxies and active galactic nuclei. The second instrument, ART-XC, is a Russian high-energy X-ray telescope. This instrument and spacecraft are being built under the leadership of the Russian Space Research Institute (IKI).

Spacecraft[edit]

The Spektr-RG programme was revived in 2005,[clarification needed][5] by 2016 construction was finished, and by mid-2018 it was under integration and testing. It is scheduled to be launched in March 2019.[4][1] The observatory is being integrated to a "Navigator" satellite bus.[6]
