South Koreas largest satellite launched on Nuri rocket in ambitious space mission

In a significant leap for its space program, South Korea successfully launched its largest satellite to date aboard the domestically developed Nuri rocket early Thursday morning. This marks the fourth of six planned launches scheduled through 2027. The three-stage Nuri rocket took off from the nation’s spaceport located on an island in the southwestern region of Goheung. Aerospace officials reported that the rocket successfully deployed a 516-kilogram science satellite along with 12 microsatellites into an orbit approximately 600 kilometers above Earth. The Korea Aerospace Administration is expected to confirm shortly whether the satellites are transmitting signals as intended. The primary satellite is fitted with a wide-range airglow camera, designed to monitor auroral activities, alongside various systems for measuring plasma and magnetic fields. Additionally, it will facilitate life-science experiments in the unique environment of space. The smaller cube satellites, developed by university teams and research institutions, are equipped with GPS technology for atmospheric studies, infrared cameras to monitor oceanic plastic, and systems aimed at testing solar cells and communication devices. This launch is particularly noteworthy as it is the first Nuri rocket mission since May 2023, when the vehicle successfully put a 180-kilogram observation satellite into orbit. Overall, this marks the fourth launch since the initial attempt in October 2021, which ended in failure when a dummy payload could not be delivered. Looking ahead, additional launches are slated for 2026 and 2027, part of a broader initiative to enhance South Korea's space capabilities and reduce its technological gap with leading Asian nations in space exploration, including China, Japan, and India. The Nuri rocket, powered by five 75-ton-class engines in its first two stages and a 7-ton-class engine in its final stage, operates primarily using domestic technology—a pivotal development for a country that has historically depended on foreign assistance for its satellite launches since the 1990s. The Naro Space Center, South Korea's sole spaceport, experienced its first successful launch in 2013 with a two-stage rocket that utilized Russian technology, following years of setbacks and failures. Notably, the rocket reached its intended altitude during a test flight in 2009 but was unable to deploy a satellite, and it exploded shortly after liftoff during a subsequent test in 2010.
