## Why It Matters
Cosmos 1890 represents a specific data point within the extensive Soviet "Cosmos" program, which served as the blanket designation for a wide variety of Soviet military and scientific satellites during the Cold War. Launched in the late 1980s, this mission illustrates the operational tempo of the Soviet space program during that era.

The mission is significant for its utilization of the Tsyklon-2 launch vehicle, a robust rocket system known for its role in deploying military payloads. By recording the specific launch site (Baikonur Cosmodrome Site 90) and precise timing, this entry contributes to the historical record of spaceflight activities. While the specific instrumentation of Cosmos 1890 remains classified or general in this context, its classification as a military satellite highlights the continued prioritization of defense-related space assets by the Soviet Union in 1987.

## Notable For
*   **Military Application:** Distinguished as an asset used for military purposes rather than civilian or scientific research.
*   **Launch Vehicle:** Utilized the Tsyklon-2, a notable Soviet/Ukrainian expendable launch system.
*   **Precise Tracking:** Recorded with high specificity, including exact launch time (21:48:30) and Site 90 location.
*   **1987 Mission:** Serves as a historical record of space activity occurring in late 1987.
