## Why It Matters
Cosmos 945 serves as a specific historical data point within the extensive Soviet "Kosmos" program, which encompassed a wide array of scientific and military satellites. As a Strela-1M satellite, it represents a continuation of the engineering and operational standards maintained by the Soviet Union during the Cold War space race. Its launch via the Kosmos-3M rocket from Plesetsk Cosmodrome highlights the heavy reliance on this specific launch site and vehicle for deploying satellite constellations during the late 1970s.

The detailed tracking of this object—cataloged as 1977-079G with a precise launch time of 18:20:00—illustrates the rigorous documentation standards applied to orbital assets. These records allow researchers and historians to reconstruct the timeline and scale of Soviet orbital activities, providing insight into the frequency and logistics of space missions conducted from the Plesetsk facility.

## Notable For
*   **Strela-1M Classification:** Identified as a specific instance of the Strela-1M satellite system.
*   **Precise Launch Chronology:** Recorded with a specific launch time of 18:20:00 on August 24, 1977.
*   **Site 132 Deployment:** Distinguished by its launch from Plesetsk Cosmodrome Site 132.
*   **Dual Identifiers:** Officially tracked via both COSPAR ID (1977-079G) and Satellite Catalog Number (10291).
*   **Wolfram Integration:** Recognized within the Wolfram Language dataset as `Entity["Satellite", "10291"]`.

## Body
### Designation and Classification
Cosmos 945 is officially classified as a **Strela-1M** satellite. The entity is aliased simply as "Kosmos 945" and is assigned the Satellite Catalog Number (SCN) **10291**. Its international designator under the Committee on Space Research (COSPAR) system is **1977-079G**. These identifiers distinguish it from other objects launched in 1977 and ensure unique tracking in orbital databases.

### Launch Logistics
The satellite's deployment was a "significant event" categorized as a rocket launch. This event took place on **August 24, 1977**. The launch originated from the **Plesetsk Cosmodrome Site 132**, a major spaceport located in Russia (then part of the Soviet Union). The specific time of the launch event was recorded at **18:20:00**.

### Launch Vehicle
The delivery system used for Cosmos 945 was the **Kosmos-3M**. This rocket is a two-stage launch vehicle of Russian origin. While the satellite and launch site were Soviet assets, the Kosmos-3M rocket is noted in records as a Russian rocket class utilized frequently for placing light-class payloads into Low Earth Orbit. The vehicle is linked to the Soviet Union in historical context but defined structurally by its Russian designation.
