Yantar-related Missions

Some of the 1972-1975 Zenit-2M missions were used to evaluate and test equipment intended for Yantar - the Zenit replacement.

The main mission of the spacecraft as a reconnaissance satellite was not affected in any way. Test equipment for the Yantar electronics, navigation and computing systems were housed in Nauka autonomous modules. Tests of the Yantar film-carrying re-entry modules probably involved the capsule being on a structure fitted in the space normally occupied by the Nauka.

Cosmos 525 (Zenit-2M 11Ф690, Gektor)       1972-083A       6248
Nauka/Yantar:  16КС №1
1972 Oct 18, 11:59 UTC
Plesetsk Cosmodrome
Voskhod 11A57
1972 Oct 19:  207 x 269 km,  65.4 deg,  89.3 min
Photo-reconnaissance satellite - recovered after 12 days. Carried Nauka autonomous module that tested components of the Condor control unit for the upcoming Yantar series - it was separated about day 9 of the flight.

1973 Mar 22:  203 x 311 km,  72.9 deg,  89.7 min
Photo-reconnaissance satellite - recovered after 12 days. Carried Nauka autonomous module that tested components of the Condor control unit for the upcoming Yantar series - it was separated about day 4 of the flight.

Voskhod 11A57
1973 Oct 03:  206 x 287 km,  65.5 deg,  89.5 min
Photo-reconnaissance satellite - recovered after 6 days. Also carried a test re-entry capsule for Yantar. Separation of the Yantar capsule's re-entry aeroshell failed and prevented deployment of the parachute. The capsule was subsequently destroyed on impact.
