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,[1] but the current launch date estimate is 2023.[2]

The observatory

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.

History

In October 2012, tests of antennas of space telescope were completed.[3]

Participating nations

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.
