## Why It Matters
Cosmos 819 is a representative example of the Zenit 2M series of Soviet reconnaissance satellites. As an element of the Soviet Union’s space and intelligence programs of the 1970s, its launch demonstrates continued operational use of the Zenit 2M platform and the Voskhod launch vehicle from Baikonur Cosmodrome. The mission contributes to the historical record of Cold War-era satellite reconnaissance deployments and reflects the Soviet practice of assigning Kosmos designations to military and governmental spacecraft. Identification metadata such as COSPAR ID 1976-045A and SCN 08853 enable tracking and cataloging in international satellite registries and computational systems (for example, the provided Wolfram Language entity). The satellite’s documented launch time, vehicle, and pad details are useful for researchers compiling timelines of Soviet launches, vehicle usage, and Baikonur launch-site activity in the mid-1970s.

## Notable For
