World Space Observatory
Ukraine
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. 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; as of January 2026, the launch is expected to take place no earlier than 2031 atop an Angara A5M rocket from Vostochny Cosmodrome.
