The Orion 1 space astrophysical observatory was installed in the orbital station Salyut 1. It was designed by Grigor Gurzadyan of Byurakan Observatory in Armenia. It was operated in June 1971 by crew member Viktor Patsayev, who thus became the first man to operate a telescope outside the Earth's atmosphere. Spectrograms of stars Vega and Beta Centauri between wavelengths 2000 and 3800 Å have been obtained.
