## Why It Matters
Cosmos 758 serves as a specific historical data point within the extensive Soviet "Cosmos" program, which designated a vast array of military and scientific satellites. As a Yantar-2K satellite, it represents the technological progression of Soviet reconnaissance capabilities during the Cold War. The Yantar-2K series was a crucial component of space-based intelligence gathering, and the launch of Cosmos 758 contributed to the operational tempo of these surveillance efforts.

Furthermore, the mission highlights the reliance on the Soyuz-U launch vehicle, a workhorse of the Soviet space fleet described as the "Universal" variant. By documenting specific missions like Cosmos 758, including precise timestamps and launch facilities like Plesetsk Cosmodrome Site 43, researchers can better understand the deployment patterns and logistical scale of Soviet space operations in the mid-1970s.

## Notable For
*   Being a specific deployment of the **Yantar-2K** Soviet spy satellite platform.
*   Utilizing the **Soyuz-U** rocket, a standard launch vehicle for Soviet missions.
*   Launching from the **Plesetsk Cosmodrome**, a primary site for military space launches.
*   Maintaining a precise launch record down to the second (**14:49:59**).
*   Being tracked under the specific **Satellite Catalog Number 08191**.
