eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the core instrument on the Russian Spektrum-Roentgen-Gamma (SRG) mission, which was successfully launched from Baikonur on July 13th 2019. As of spring 2023 eROSITA performed four and a half all-sky surveys, mapping the whole X-ray sky with an XMM-Newton type sensitivity. In the 0.2-2.4 keV band it is about 30 times more sensitive than ROSAT, while in the 2.0-8.0 keV band it provides the first ever true imaging survey of the sky. Its design driving science is the detection of large samples of galaxy clusters to redshifts z > 1 in order to study the large scale structure in the Universe and to test cosmological models including Dark Energy. Although considered to be "secondary science" the currently available data provide a world of exiting new results also for galactic sources, including Neutron Stars and Pulsars, X-ray binaries, active stars and diffuse emission from supernova remnants. In my talk I will report on the status of the eROSITA mission and its scientific prospects with the main focus on selected supernova remnants and compact objects.
