## Why It Matters
Cosmos 1758 serves as a specific historical data point within the extensive Soviet "Cosmos" program, which utilized a generic naming convention to classify a wide array of military and scientific satellites. As a Tselina-D satellite, its primary significance lies in its role within Soviet signals intelligence (SIGINT) operations during the Cold War era. These satellites were designed to detect and locate radio emissions, contributing to the electronic order of battle.

The launch of Cosmos 1758 also highlights the operational reliance on the Tsyklon-3 launch vehicle during the mid-1980s. By documenting specific launch details—such as the exact UTC time and the specific site (Plesetsk Site 32)—this entry contributes to the broader historical record of spaceflight logistics and the deployment of space-based surveillance assets. Its inclusion in databases with a specific Wolfram Language entity code further underscores its relevance in astrometric tracking and space history documentation.

## Notable For
- **Signals Intelligence:** Being a specific unit of the Tselina-D class, dedicated to Soviet electronic surveillance.
- **Launch Precision:** Having a recorded launch time精确 to the second (04:43:00 UTC).
- **Launch Infrastructure:** Utilizing Plesetsk Cosmodrome Site 32, a key Soviet launch complex.
- **Nomenclature:** Serving as an example of the Soviet practice of designating diverse military satellites under the anonymous "Cosmos" label.
