eROSITA (extended ROentgen Survey with an Imaging Telescope Array) will be the core instrument on the Russian Spektrum-Roentgen-Gamma (SRG) mission which is scheduled for launch in 2012. eROSITA is completely approved and funded by the German Space Agency DLR. The design driving science is the detection of 100 thousands Clusters of Galaxies up to redshifts z > 1 in order to study the large scale structure in the Universe and test cosmological models including the Dark Energy. This will be accomplished by an all-sky survey lasting for four years plus a phase of pointed observations on selected objects. eROSITA consists of seven Wolter-I telescope modules, each equipped with 54 Wolter-I shells having an outer diameter of 360 mm. In the focus of each mirror module, a framestore pn-CCD provides a field of view of 1° in diameter.
eROSITA is fully approved and funded by the German Space Agency DLR and Max-Planck-Society. As a recent major milestone, a "Detailed Agreement” between DLR and Roskosmos was signed on August 18, 2009. The instrument is in part (e.g., the mirror production) in phase C/D.
