Soyuz 13 was a second test flight of the redesigned Soyuz capsule that first flew as Soyuz 12. This particular spacecraft was further specially modified to carry a Orion 2 Space Observatory; Orion 1 Space Observatory was installed onboard space station Salyut 1.

[edit] Orion 2 Space Observatory
The Orion 2 Space Observatory also designed by Grigor Gurzadyan was operated by crew member Valentin 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-grade quartz prism objective. The dispersion of the spectrograph was 170, 280 and 550 Å mm-1, at wavelengths of 2,000, 2,500 and 3,000 Å, respectively. The first satellite UV spectrogram of a planetary nebula (IC 2149 in Auriga) was obtained, revealing lines of aluminum and titanium - elements not previously observed in objects of that type. Two-photon emission in that planetary nebula and a remarkable star cluster in Auriga were also discovered.
Once again, the new Soyuz variant performed extremely well when on-board systems were tested.
