Cosmos 805



Cosmos 805 was a Soviet surveillance satellite launched from the Plesetsk Cosmodrome aboard a Soyuz rocket. It was the 4th Yantar-2K and the first with 2 SpK small film recovery capsules, and the first flight of the completely equipped satellite. The main reentry capsule and its film cargo were returned successfully. Both SpK capsules successfully separated from the Yantar in the course of the flight, but neither was recovered. The parachutes of the first did not deploy and the capsule crashed into the ground. The solid motor of the second capsule did not fire as programmed and the capsule did not deorbit at the expected time.
