Astron was a Soviet space telescope launched on 23 March 1983 at 12:45:06 UTC, using the Proton-K rocket.[1] Based on the 4MV spacecraft design and operational for six years, Astron was the largest ultraviolet space telescope of its time.

The project was headed by Alexandr Boyarchuk.Template:R The spacecraft was designed and constructed by the Crimean Astrophysical Observatory and NPO Lavochkin. A group of scientists from these institutions was awarded the USSR State Prize for their work.[2]

The payload consisted of an 80 cm ultraviolet telescope, which was jointly designed by the USSR and France, and an X-ray spectroscope.[3] It could take UV spectra 150-350 nm.[4]

Placed into an orbit with an apogee of Template:Convert, Astron was capable of making observations outside the Earth's umbra and radiation belt.

Among the most important observations made by Astron were those of SN 1987A supernova from March 4 to March 12, 1987,[5] and of Halley's Comet in December 1985, the latter of which enabled a group of Soviet scientists to develop a model of the comet's coma.[4]

Operation of the observatory ended on 23 March 1991.[6]
