388:. It achieved first light on 17 October 2019 and completed its first all-sky survey on 11 June 2020. In the summer of 2021 the first eROSITA X-ray data release to the public was announced. The operations of eROSITA were suspended on 26 February 2022 after the Russian attack into Ukraine. The science operations of the instrument were paused, but the analysis of the data already received in Germany continued. At the time, eROSITA had completed four of its planned eight full-sky surveys. In June 2022, Roscosmos announced its intent to restore the operation of eROSITA unilaterally, which was criticized by experts for its potential to damage the telescope.
