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][4] It is an international project led by Russia (Roscosmos), with participation from Spain and Japan. The launch had initially been planned for 2007, but has since been continually delayed;[5] as of December 2023[update], the launch is expected to take place no earlier than 2030[1] atop an Angara A5M rocket from Vostochny Cosmodrome.[2]

The main instrument of the observatory is a 1.7-metre Ritchey–Chrétien telescope. The telescope will be equipped with the following instruments:
The WUVS spectrographs assembly consists of four channels:
The FCU has two channels, each fed by an independent pick off mirror:
In October 2012, tests of antennas for the space telescope were completed.[8]
In July 2019, INASAN selected the first seven experiments to be performed by the observatory.[9]
Spektr-UV is an international project led by Russia (Roscosmos). At present the international cooperation includes three basic participants: Russia (will provide the telescope, spacecraft, launch facilities, ground segment); Spain (FCU detectors, ground segment); Japan (UVSPEX).
