Spektr-RG (Russian for Spectrum + Röntgen + Gamma; also called Spectrum-X-Gamma, SRG, SXG) is an international high-energy astrophysics observatory, which is being built under the leadership of the Russian Space Research Institute (IKI). Spektr-RG instrumentation includes 5 telescopes spanning the energy range from the far ultraviolet to the hard X-ray, plus an all-sky monitor.
Development of an early version with the same name was canceled in 2002.[3]

Development of an early version of Spektr-RG was started in mid-'90s and was finally canceled in 2002.[3] Initial launch date was set to 1995,[7] but later postponed as far as 2008, until it was finally cancelled in 2002.[3] However, some of the instruments have been completed, e.g., an X-ray telescope by Leicester University (JET-X)[8] and an ultraviolet telescope by Tel-Aviv University (TAUVEX).
[edit] Current Spektr-RG
The successor of the early Spektr-RG was initiated in 2005[2] and is currently in development and scheduled for launch in Q1 2013.[1] The observatory is intended to study interplanetary magnetic field, galaxies, black holes.[9]
