A European rocket successfully launched South Korea’s advanced Earth-observation satellite, KOMPSAT-7, today, December 1, 2023. The launch took place from the European Spaceport in Kourou, French Guiana, at 12:21 p.m. EST (17:21 GMT; 14:21 local time). Operated by French aerospace company Arianespace, the event was streamed live, allowing global audiences to witness the mission.
The KOMPSAT-7 spacecraft, weighing approximately 1,810 kilograms (3,990 pounds), was developed by the Korea Aerospace Research Institute. It marks a significant advancement in satellite technology, serving as the successor to KOMPSAT-3A, which was launched in March 2015. According to Arianespace, KOMPSAT-7 is “one of the world’s most advanced ultra-high-resolution optical satellites.” The satellite is designed to enhance detailed observation of the Korean Peninsula and cater to the increasing demand for high-quality satellite imagery.
Key Features of KOMPSAT-7
KOMPSAT-7 incorporates optical data transmission technology, a first for a Korean satellite. This feature enables real-time processing of large volumes of Earth-observation imagery through advanced electro-optical modules and onboard storage systems. The satellite’s capabilities will significantly improve the quality and efficiency of data collection for various applications, including environmental monitoring and urban planning.
The launch, designated VV28, is the sixth mission for the Vega C rocket, which stands at 35 meters tall. Developed by the European Space Agency, the Vega C has successfully completed four out of its five previous launches, with its only failure occurring during its second mission in December 2022. If the launch proceeds as planned, KOMPSAT-7 will be deployed into a sun-synchronous orbit approximately 576 kilometers (about 358 miles) above Earth, ensuring consistent lighting conditions for its observational tasks.
Importance of Sun-Synchronous Orbit
Satellites in sun-synchronous orbits circle the Earth’s poles, allowing them to pass over specific areas at the same solar time each day. This characteristic is particularly advantageous for Earth-observing missions, as it provides uniform lighting for imaging and monitoring changes over time.
The successful deployment of KOMPSAT-7 represents a significant step forward in South Korea’s satellite capabilities, enhancing its ability to conduct critical Earth observation and respond to national needs for high-quality data. As the global demand for accurate and timely satellite imagery continues to grow, this mission underscores the importance of international collaboration in advancing space technology.
