## FAQs
### Q: What type of satellite was Cosmos 377?
A: Cosmos 377 was a Soviet Zenit 2M spy satellite. These satellites were part of the Soviet Union's reconnaissance program.

### Q: When and where was Cosmos 377 launched?
A: The satellite launched on November 11, 1970, at 09:20:01 UTC from the Baikonur Cosmodrome Site 31.

### Q: What rocket was used to launch Cosmos 377?
A: Cosmos 377 was launched using a Voskhod rocket, which was a Russian launch vehicle used for both crewed and uncrewed missions during the Soviet era.

## Why It Matters
Cosmos 377 serves as a specific historical data point within the extensive Soviet Cosmos program. Launched in 1970, it represents the ongoing operational tempo of Soviet military reconnaissance during the Cold War. The mission illustrates the Soviet reliance on the Zenit series for intelligence gathering, utilizing the specific "2M" variant which suggests an upgraded or modified configuration of the standard design.

Furthermore, the mission highlights the utility of the Voskhod launch vehicle. While the Voskhod program is historically famous for carrying the first multi-person crews and the first spacewalk, its use for Cosmos 377 demonstrates its dual-role capability as a reliable delivery system for military payloads like the Zenit satellite class. By verifying specific technical details—such as the precise launch time (09:20:01) and the specific launch pad (Site 31)—this entity provides granular accuracy for researchers modeling the history of spaceflight and orbital activities.

## Notable For
*   **Specific Reconnaissance Variant:** Being identified as a Zenit 2M, distinguishing it from earlier or standard models in the Zenit spy satellite family.
*   **Voskhod Launch Compatibility:** Representing a convergence of the Voskhod launch vehicle technology with military satellite deployment.
*   **Precise Tracking Data:** Having well-documented identifiers, including COSPAR ID 1970-096A and Satellite Catalog Number 04695, facilitating precise historical tracking.
*   **Launch Infrastructure:** Utilizing Baikonur Cosmodrome Site 31, a specific launch complex distinct from the more commonly cited Site 1.

## Body
### Mission Identity and Classification
Cosmos 377 is formally classified as a **Zenit 2M**, a type of Soviet spy satellite. In the context of international space tracking, it is identified by the **COSPAR ID 1970-096A** and the **Satellite Catalog Number (SCN) 04695**. The entity is also aliased as "Kosmos 377" and has been indexed in various knowledge bases, including the Google Knowledge Graph (ID: `/g/1218xl59`) and the Wolfram Language entity code `Entity["Satellite", "04695"]`.

### Launch Details
The satellite's deployment was a significant event recorded with high precision:
*   **Date:** November 11, 1970
*   **Time:** 09:20:01
*   **Location:** Baikonur Cosmodrome Site 31
*   **Vehicle:** Voskhod

The launch vehicle used was the **Voskhod**, a Russian launch vehicle derived from the R-7 Semyorka family. While the Voskhod class is historically noted for its role in the Soviet crewed spaceflight program, for this mission, it served as the delivery system for the uncrewed Zenit 2M reconnaissance payload.

### Related Entities
The technical ecosystem of Cosmos 377 involves distinct hardware classes:
*   **Zenit 2M:** The specific class of the satellite, defined as a Soviet spy satellite.
*   **Voskhod:** The launch vehicle class, associated with both Russian launch vehicles and the series of Soviet crewed spacecraft.
