Spektr-UV

The Spektr-UV, also known as World Space Observatory-Ultraviolet (WSO-UV), is a proposed ultraviolet space telescope intended for work in the 115 nm to 315 nm wavelength range.[3] Launch had initially been planned for 2007, but has since been continually delayed;[4] as of March 2020, the launch is planned for October 2025[1][5] atop an Angara A5 rocket from Vostochny Cosmodrome.[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 for the space telescope were completed.[6]

In July 2019, INASAN selected the first seven experiments to be performed by the observatory.[7]

Participating nations

Spektr-UV is an 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 are also participants in the project.
