Soyuz 12 . This particular spacecraft was further specially modified to carry aOrion 2 Space Observatory (seeOrion 1 and Orion 2 Space Observatories );Orion 1 Space Observatory was installed onboard space stationSalyut 1 .Crew

The Orion 2 Space Observatory also designed by
Grigor Gurzadyan was operated by crew memberValentin Lebedev .Ultraviolet spectrograms of thousands of stars to as faint as 13th magnitude were obtained by a wide-angle meniscus telescope of the Cassegrain system, with an aperture diameter of 240 mm, an equivalent focal length of 1,000 mm, and a 4-gradequartz prism objective . The dispersion of the spectrograph was 17, 28 and 55 nm/mm, at wavelengths of 200, 250 and 300 nm respectively. The first satellite UV spectrogram of aplanetary nebula (IC 2149 in Auriga) was obtained, revealing lines ofaluminium andtitanium - elements not previously observed in objects of that type. Two-photon emission in that planetary nebula and a remarkablestar cluster in Auriga were also discovered.Once again, the new Soyuz variant performed extremely well when on-board systems were tested.
The landing was in a snow storm.
