## Why It Matters
Cosmos 1829 serves as a historical data point within the Soviet space program, specifically regarding military communication infrastructure during the late Cold War era. As part of the Strela-3 series, it represents the technological progression of satellite communications utilized by the Soviet military, a capability later associated with Ukrainian space systems following the dissolution of the USSR.

The entry is significant for tracking the history of the Tsyklon-3 launch vehicle, a joint Soviet/Ukrainian rocket design. The specific details recorded for Cosmos 1829—such as the precise launch time and site coordinates at Plesetsk—contribute to the accurate cataloging of space objects (SCN 17584). This data helps historians and analysts understand the operational tempo and launch capabilities of the Plesetsk Cosmodrome in the 1980s.

## Notable For
*   **Specific Military Role:** It is explicitly classified as a military communications satellite (Strela-3).
*   **Precise Launch Data:** The entry includes a precise launch timestamp down to the second (13:11:56).
