Russia wants to restart Germany’s black-hole searching space telescope


Russia wants to restart a German black-hole searching telescope that went to space aboard a Russian satellite in 2019. Germany ordered the telescope mothballed in early March in response to Russia’s February invasion of Ukraine. 

The telescope, called eROSITA and mounted on the Russian Spektr-RG spacecraft, scans the sky for sources of X-ray radiation (black holes and neutron stars) and works in tandem with Russia’s ART-X instrument that searches for supermassive black holes.
