World Space Observatory: ultraviolet mission: status 2022

Abstract

The World Space Observatory–Ultraviolet mission (Spektr-UF, WSO-UV) is an efficient multipurpose orbital observatory for high- and low-resolution spectroscopy, high sensitivity imaging and slitless spectroscopy in the ultraviolet wavelength range. It will open new opportunities in (exo)planetary science, extragalactic astronomy, stellar astrophysics and cosmology. The observatory is based on a complex of scientific instruments including the T-170M telescope (aperture 170 cm), spectrographs and imagers. The payload should be ready in 2025. We briefly describe the current status of the mission.
