The Spektr-UV, also known as World Space Observatory-Ultraviolet (WSO-UV), is a proposed space telescope intended for work in the 110 nm to 320 nm wavelength range. Initially, the launch was planned for 2017. Later, it was announced about possible 2021 launch.〔(На "русский Хаббл" не хватило денег )〕 == The observatory == The main instrument of the observatory is 1.7-metre Ritchey-Chretien telescope. The telescope will be equipped by the following instruments: * HIRDES (High-Resolution Double Echelle Spectrograph): R~55000 spectroscopy of point sources in the 102-320 nm range (Germany) * LSS: Long-slit low-resolution (R~2500) spectroscopy in the 102-320 nm range * ISSIS (Imaging and Slitless Spectroscopy Instrument for Surveys) being developed to carry out UV and optical diffraction limited imaging of astronomical objects. The ISSIS incorporates three channels:High Sensitivity Far-UV Channel: 120-200 nm; Channel for Surveys (FUV): 120-600 nm, optimized for 120-270 nm; Channel for Surveys (UVO): 120-600 nm, optimized for 270-600 nm.
