Spektr RG
Spektrum-Röntgen-Gamma
Spektr RG is a joint Russian-German project intended to chart a detailed map of
the sky in the X-ray band. The space observatory will be scanning the sky in a
broad energy band with high sensitivity and angular resolution.
The Spektr-RG orbit observatory carries two payloads: Russian-made Astronomical
Roentgen Telescope - X-ray Concentrator (ART-XC) and German-made Extended
Roentgen Survey with an Imaging Telescope Array (eROSITA). The German payload
was shutdown in Feb 2022 by the Ukrain war sanctions.
The telescope's research mission is set to last for six-and-a-half years
including a four-year scan of the heavens and the remainder spent observing
objects in space, Roskosmos said.
