The Orion space telescopes were a series of two instruments flown aboard Soviet spacecraft during the 1970s to conduct ultraviolet spectroscopy of stars.

👉 Orion (space telescope) in the context of Salyut 1
Salyut 1 (Russian: Салют-1, lit. 'Salute 1'), also known as DOS-1 (Durable Orbital Station 1), was the world's first space station. It was launched into low Earth orbit by the Soviet Union on April 19, 1971. The Salyut program subsequently achieved five more successful launches of seven additional stations. The program's final module, Zvezda (DOS-8), became the core of the Russian Orbital Segment of the International Space Station and remains in orbit today.
Salyut 1 was adapted from an Almaz airframe and comprised five components: a transfer compartment, a main compartment, two auxiliary compartments, and the Orion 1 Space Observatory. It was visited by the Soyuz 10 and Soyuz 11 missions. While the crew of Soyuz 10 was able to soft dock, the hard-docking failed, forcing the crew to abort their mission. The Soyuz 11 crew successfully docked, spending 23 days aboard Salyut 1 conducting experiments. The Soyuz 11 crew died of asphyxia caused by a valve failure just before reentry, making them the only humans to have died above the Kármán line.

Orion (space telescope) in the context of Space telescope
A space telescope (also known as space observatory) is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory, OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971. Space telescopes avoid several problems caused by the atmosphere, including the absorption or scattering of certain wavelengths of light, obstruction by clouds, and distortions due to atmospheric refraction such as twinkling. Space telescopes can also observe dim objects during the daytime, and they avoid light pollution which ground-based observatories encounter. They are divided into two types: Satellites which map the entire sky (astronomical survey), and satellites which focus on selected astronomical objects or parts of the sky and beyond. Space telescopes are distinct from Earth imaging satellites, which point toward Earth for satellite imaging, applied for weather analysis, espionage, and other types of information gathering.
