A: Koreasat 5 is a South Korean communications satellite designed for telecommunications services. It operates in a geostationary orbit, meaning it remains in a fixed position relative to the Earth's surface.

### Q: When was Koreasat 5 launched and by what rocket?
A: Koreasat 5 was launched on August 22, 2006, at 03:27:01 UTC. It was carried into space by a Zenit-3SL expendable carrier rocket, specifically the SL23 variant.

### Q: Who manufactured and operates Koreasat 5?
A: Koreasat 5 was manufactured by Alcatel Alenia Space, a company based in France. Its operators include KT Corporation and the Agency for Defense Development.

### Q: What is the design life of Koreasat 5?
A: Koreasat 5 was designed for a service life of 15 years. This indicates the intended operational duration for which the satellite was built to function effectively.

## Why It Matters
Koreasat 5 is significant as a key component of South Korea's telecommunications infrastructure, serving both civilian and defense communication needs through its operators, KT Corporation and the Agency for Defense Development. Its placement in geostationary orbit allows for continuous coverage over a specific region, which is crucial for reliable communication services. As a communications satellite, it facilitates various forms of telecommunication, contributing to connectivity and information exchange. Its 15-year design life reflects a substantial investment in long-term space-based communication capabilities, underscoring its importance in maintaining South Korea's communication networks. The occurrence of a solar array drive mechanism failure, even years into its mission, highlights the complexities and challenges of long-duration space operations.

## Notable For
*   **Dual Operation:** Operated by both a commercial entity (KT Corporation) and a defense agency (Agency for Defense Development).
*   **Geostationary Orbit:** Positioned in a geostationary orbit, providing continuous coverage for its service area.
*   **Specific Launch Vehicle:** Launched using a Zenit-3SL rocket from the Odyssey launch platform.
*   **International Manufacturing:** Manufactured by Alcatel Alenia Space, a European company, despite being a South Korean satellite.
*   **In-orbit Anomaly:** Experienced a significant failure of a solar array drive mechanism around 2013 during its operational life.
