Flight

Launch from the Baikonur Cosmodrome; landing 200 km southwest of Karaganda.

Soyuz 13 performed a unique test flight of the 7K-T/AF modification of the Soyuz spacecraft.

On board was the large Orion 2 astrophysical camera. The crew performed astrophysical observations of stars in the ultraviolet range with this camera.

The Orion 2 Space Observatory, 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 17, 28 and 55 nm/mm, at wavelengths of 200, 250 and 300 nm respectively. The first satellite UV spectrogram of a planetary nebula (IC 2149 in Auriga) was obtained, revealing lines of aluminium 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. Additionally, comet Kohoutek was observed.

Spectrozonal Earth photography, testing of on-board systems and biological explorations (OASE 2) in view of later planned long termed missions were other experiments. Some of this experiment should have been done on the Saylut 2 station, but the station failed in orbit.

The recovery of the capsule was problematic because of a snowstorm.
