eROSITA and Dark Energy

Spectrum-Roentgen-Gamma (SRG) is a bilateral space mission of Russia and Germany with the German contribution of the primary payload, the X-ray telescope eROSITA. eROSITA will systematically scan the entire sky for four years with unprecedented sensitivity. The primary science goal is the determination of the large scale structure of the universe and how these structures evolved over cosmic times. This could aid to unlock the secrets of the enigmatic Dark Energy which drives the universe apart. The first scientific results confirm our confidence to reach the mission goals.
