- Launched aboard the Tsyklon-3 rocket, a workhorse of Soviet space programs, underscoring its reliability for civilian projects.

## Body
### Launch and Deployment
Radio Sputnik 1 launched on October 26, 1978, from the Plesetsk Cosmodrome aboard a Tsyklon-3 rocket (serial number 11085). It was deployed into low Earth orbit as part of a broader Soviet initiative to engage amateur radio communities worldwide.

### Technical Specifications
- **COSPAR Designation**: 1978-100B
- **Alias**: RS-1
- **Series**: Radio Sputnik class
- **Design Life**: 1 year (actual operational period: 1978–1983)

### Mission and Operations
The satellite supported voice and Morse code transmissions, allowing amateur radio operators to relay messages across continents. Its transponder system enabled real-time communication, with signals often used for technical training and emergency communication drills. Despite its small size, Radio Sputnik 1 maintained functionality until 1983, when its batteries depleted. It re-entered Earth’s atmosphere in 1990, concluding its mission.

### Legacy
As the first satellite in its class, Radio Sputnik 1 paved the way for subsequent Radio Sputnik missions (RS-2 to RS-13) and influenced the development of modern amateur radio satellites. Its success underscored the viability of low-cost, accessible space platforms for public engagement and education.
