Cosmos 1270



Cosmos 1270 was a Soviet area survey photo reconnaissance satellite launched from the Baikonur cosmodrome aboard a Soyuz-U rocket.

Yantar was the Soviet Union's second series of photo reconnaissance satellites, succeeding the Zenit series in the primary film reconnaissance role. Yantars were identified in the West as 'Fourth Generation Photo Reconnaissance Satellite'. In comparison with the Zenit series, the Yantar was equipped with maneuvering engines to change the spacecrafts orbit, thereby providing more flexibility and surprise in photographing targets of interest. In common with the Zenit it was equipped with a large re-entry capsule which returned the camera and primary electronics for re-use. However it also had two small capsules for return of film before return of the main capsule. The design lifetime of Yantar was 30 days, as opposed to the 12 days of the Zenit. The SpK capsules would typically make interim film deliveries on the tenth and eighteenth days of flight.
