Following the fifth flight of the Nuri (KSLV-II) launch vehicle, the Korea Aerospace Administration (KASA) and the Korea Aerospace Research Institute (KARI) confirmed that nine of the ten secondary satellites successfully established communication with ground stations. While the Quaternion Purset-2 satellite failed to deploy from its launch container, the remaining nine satellites—including those from Spacelintech, KARI, the Unmanned Exploration Research Institute, and Space & Bin—achieved two-way communication on the day of the launch. Other payloads, such as Daejeon-Sat 1 and Chosun University’s space optical communication verification satellite, also confirmed successful deployment and data transmission. Officials noted that the time required to establish communication was “significantly shorter” than during the fourth launch, suggesting enhanced technical maturity in the Nuri launch vehicle regarding orbital injection and positioning accuracy. Further developments involve the New-space Earth Observation Satellite Constellation for National Safety (NEONSAT). A constellation of five microsatellites (Nos. 2 through 6) launched on October 7 aboard a Nuri rocket successfully captured and transmitted ~~its~~ their first Earth-observation images within 15 14 hours and 29 minutes of launch. KASA and the Korea Advanced Institute of Science and Technology (KAIST) confirmed that power generation, attitude control, and communications are operating normally. The ~~NEONSAT project is designed for national security~~ initial imagery includes 1m-resolution captures of locations in the United States, such as Cleveland, Ohio, and ~~disaster response, with plans to expand~~ Montgomery, Alabama. The rapid data acquisition was attributed to ~~10 satellites. An additional five satellites are scheduled for launch on~~ automated deployment concepts and expertise from previous missions. Over the ~~Nuri’s sixth flight next year.~~ coming months, agencies will perform image calibration and position the satellites into a constellation. Control is expected to transfer to the National Satellite Operation Center on Jeju Island in 2025. This progress aligns with South Korea’s goal to transition to a private-sector-led space ecosystem by 2029.
