Soyuz 13 is the mission name for the flight of a Soviet Soyuz spaceship that started on December 18, 1973 . It was the 24th flight in the Soviet Soyuz program. After Soyuz 12 , an unmanned test flight was carried out with Kosmos 613 .

Main crew

Substitute team

Vorobyov and Yazdovsky were originally intended to be the crew for this flight, but were replaced by Klimuk and Lebedev nine days before take-off. Allegedly, Yasdovsky had fallen out with Commander Vorobyov to such an extent that neither of them flew.

The second substitute team consisted of Vladimir Kowaljonok and Juri Ponomarjow .

Mission overview

The mission served the manned testing of the second generation of Soyuz spaceships. In addition to the technological review of all systems (manual and automatic control, autonomous navigation), a number of experiments were carried out that started in Salyut 1 :

  • Use of a larger astro camera with film recording "Orion 2": aperture 280 mm, focal length 1400 mm, Cassegrain system (different spectral ranges between 220 and 360 nm, i.e. also UV )
  • A lens telescope 70 mm × 450 mm ( field of view 9 degrees) was mounted in the same mount . It should be possible to align the complex with an accuracy of 10 arc seconds.
  • The devices were also used for earth surveys.
  • Biomedical experiments ("Oasis 2")

Since no coupling was provided for the spaceship, the camera was mounted in the modified orbital section in the place of the coupling socket. There were solar panels for the energy supply.

This flight took place parallel to the long-term test of the Soyuz spaceship with Kosmos 613.
