Crew: Klimuk, Lebedev. First Byelorussian astronaut. First space mission devoted to a single scientific instrument. A unique flight of the 7K-T/AF modification of the Soyuz spacecraft. The orbital module was dominated by the large Orion 2 astrophysical camera. Backup crew: Vorobyov, Yazdovsky.

A unique flight of the 7K-T/AF modification of the Soyuz spacecraft. The orbital module was dominated by the large Orion 2 astrophysical camera. The crew conducted astrophysical observations of stars in the ultraviolet range. Additional experiments included spectrozonal photography of specific areas of the earth's surface, and continued testing of space craft's on-board systems. Recovered December 26, 1973 8:50 GMT. Landed in snowstorm 200 km SW Karaganda.

After the Soyuz 11 disaster, the Soyuz underwent redesign for increased reliability. Two solo test flights of the new design were planned. The second mission would include installation of a large astrophyscial camera. Crews for the second mission, Soyuz-13, were first named in July 1973: Vorobyev/Yazdovskiy (Prime); Klimuk/Sevastyanov (Backup); Kovalenok/Ponomarev (Support). These assignments were changed a month later to: Vorobyev/Yazdovskiy(Prime); Klimuk/Ponomarev (Backup); Kovalenok/Sevastyanov (Support). They were again revised in September 1973 to Vorobyev/Yazdovskiy (Prime); Klimuk/Lebedev (Backup); Kovalenok/Ponomarev (Support). But just before launch Klimuk/Lebedev were named as the prime crew. Maneuver Summary:
189km X 247km orbit to 186km X 255km orbit. Delta V: 2 m/s
186km X 255km orbit to 223km X 256km orbit. Delta V: 10 m/s
Total Delta V: 12 m/s.

AKA: Kavkas (Caucasus ).

  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.
