|Start of mission|
|Launch date||2023 (proposed)|
|Wavelengths||115 to 315 nm|
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. Launch had been planned for 2007 or earlier, but the current launch date estimate is 2023.
The main instrument of the observatory is a 1.7-metre Ritchey–Chrétien telescope. The telescope will be equipped with 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.

In October 2012, tests of antennas of space telescope were completed.
This international project is led by Russia (Roscosmos). At present the international cooperation includes three basic participants: Russia (will provide the telescope, spacecraft, launch facilities, ground segment); Spain (ISSIS, ground segment); Germany (spectrographs). Ukraine and Kazakhstan also participate in the project.
