About WSO-UV

The World Space Observatory - Ultraviolet (WSO-UV) is an international space telescope that will be launched in 2023 to guarantee observational access in the ultraviolet (UV) range to astronomers after the end of the Hubble Space Telescope (HST) mission.

The mission is run by an international consortium led by Russia and also involving Spain. This is the web page of the Spanish team. Visit here the Russian site.

WSO-UV (Spectrum-UF) is part of the scientific program of the Russian Space Agency, ROSCOSMOS. The aim of the “WSO-UV” project is the creation of a space observatory destined for an operation in UV area which is inaccessible for an earth-based observation. Access to the ultraviolet (UV) range of the electromagnetic spectrum is fundamental for astrophysics, from the study of life emergence environments to the understanding of chemical evolution and mixing for the last 10,000 million years of the Universe, about 80% of the Universe life. For this reason, there has always been an UV telescope in orbit, currently the Hubble Space Telescope (HST).

The World Space Observatory-Ultraviolet (WSO-UV) mission will cover the gap between the end of HST and the advenment of future, currently under study, large 10-m primary space projects such as LUVOIR.

WSO-UV is a 170 cm primary space telescope, equipped with instrumentation for imaging and ultraviolet spectroscopy; in spite its collecting area being a factor of 2 smaller than HST, it is foreseen to be more sensitive than HST because it will make use of new "state of the art" detectors. WSO-UV will become the first ultraviolet observatory unaffected by the light pollution from the Earth geocorona.

The WSO-UV premises at the Universidad Complutense of Madrid are provided by the Joint Center for Ultraviolet Astronomy (JCUVA).

The Spanish participation is funded by the Ministry of Industry, Energy and Tourism (industrial activities) and the Ministry of Economy and Competitiveness (scientific activities). The Universidad Complutense de Madrid (UCM)is the scientific responsible for Spain.
