In 2011, Russia plans to orbit a new astrophysical observatory as part of its Federal Space Program (2006-2015). The project, called Spektr Rentgen-Gamma (SRG), integrates a Russian X-ray observatory (ART) and two European programs. ART is a combination of X-ray telescopes with coded aperture and a gamma burst detector. It was conceived in the late 1980s but was never implemented because of lack of funding.
