## Why It Matters
Cosmos 1825 was part of the Soviet Union's extensive Tselina-D satellite program, which played a crucial role in electronic intelligence gathering. The Tselina-D satellites were designed to intercept and relay signals from foreign communications systems, providing the USSR with valuable strategic intelligence. Launched in 1987, Cosmos 1825 contributed to the Soviet Union's signals intelligence capabilities, supporting its Cold War-era surveillance efforts. While the satellite's specific mission details remain classified, its inclusion in the Tselina-D series highlights the Soviet Union's advanced space-based intelligence infrastructure. The launch of Cosmos 1825, along with other Tselina-D satellites, underscores the Soviet Union's commitment to maintaining a robust signals intelligence network during the Cold War.

## Notable For
- **Part of the Tselina-D series**: One of the Soviet Union's most advanced signals intelligence satellites.
- **Launched by Tsyklon-3**: Used a reliable Soviet-era launch vehicle for deployment.
- **Operated during the Cold War**: Contributed to the USSR's electronic intelligence capabilities.
- **Limited public documentation**: Few details are publicly available due to its classified nature.

## Body
### Satellite Classification
Cosmos 1825 was classified as a Tselina-D satellite, a model of Soviet signals intelligence satellite. The Tselina-D series was part of the larger Tselina program, which included both civilian and military satellites. These satellites were designed to intercept and relay electronic signals, providing the Soviet Union with critical intelligence data.

### Launch Details
The satellite was launched on March 3, 1987, at 15:03:00 UTC from the Plesetsk Cosmodrome Site 32. The launch vehicle used was the Tsyklon-3, a Soviet expendable rocket known for its reliability in deploying military and intelligence satellites. The Tsyklon-3 was developed in collaboration with Ukraine and was a key component of the Soviet space program.

### COSPAR Identification
Cosmos 1825 is officially identified by the COSPAR ID 1987-024A, which is used to track and catalog satellites. This ID helps in distinguishing the satellite from others in the Cosmos series and provides a reference for its orbital and operational details.

### Wikipedia Availability
While Cosmos 1825 is not widely documented in English-language sources, it has Wikipedia pages in Macedonian, Serbo-Croatian, and Serbian. These pages provide additional context and details about the satellite's role and significance in the Soviet space program.

### Significance in Soviet Intelligence
The Tselina-D series, including Cosmos 1825, was a critical part of the Soviet Union's signals intelligence network.
