THE SPEKTRUM-RÖNTGEN-GAMMA
(Spektr-RG) satellite, a long-delayed and much-modified X-ray astronomy package, launched successfully from the Baikonur Cosmodrome in Kazakhstan on July 13.
Once Spektr-RG reaches a stable solar orbit 1.5 million kilometres from Earth, , two telescopes aboard will commence mapping the X-ray sky. The first is the German space agency’s Extended Röntgen Survey with an Imaging Telescope Array (EROSITA); the second is the Russian-built Astronomical Röntgen Telescope – X-ray Concentrator (ART-XC).
