With the success of the 3rd launch, it has not only secured reliability and safety in launch vehicle technology but also laid the foundation for a privately-led space ecosystem through the participation of a comprehensive system conglomerate. On the 25th, at 6:24 PMNuriho soared from the Naro Space Center in Goheung, Jeollanam-do, towards the target altitude of 550 km. After 123 seconds of launch, the first-stage engine was successfully separated at an altitude of 66 km. After 230 seconds of launch, Nuriho reached an altitude of 209 km and separated the fairing that protected the payload. Subsequently, at 267 seconds of launch, it completed the separation of the second-stage engine at an altitude of 263 km. After about 13 minutes of launch, Nuriho entered the target altitude of 550 km and sequentially performed the predetermined sequence by separating the primary payload (Next-Generation Small Satellite 2)followed by six CubeSats developed by private companies and four Dove satellites developed by the Korea Astronomy and Space Science Institute, with a 20-second interval between each separation. As a result of separation, both Next-Generation Small Satellite 2 and six CubeSats were successfully deployed. However, for one of the four Dove satellites, it will take some more time to confirm the deployment. The Korea Aerospace Research Institute considers the low possibility of any issues in the final deployment results, taking into account the confirmed successful deployment of the remaining Dove satellites. Next-Generation Small Satellite 2 confirmed the reception of beacon signals (unique identification signals periodically sent from the satellite to the ground) at the Antarctic Sejong Station at 7:07 PM on the same day. From 5 AM on the 26th, detailed confirmation of the satellite's condition will be carried out through bi-directional communication between the Ground Station of the Satellite Research Institute at the Korea Advanced Institute of Science and Technology (KAIST) and the satellite, which will be conducted four times in total.

Nuriho has officially succeeded in its 3rd launch, but it also faced a crisis leading up to the launch. On the original scheduled launch day of the 24th, anomalies occurred just two hours before the launch. As a result, the launch was urgently halted. Upon inspection, it was found that the command sequence was not being properly transmitted from the launch pad's helium storage tank to the ground equipment system's programmable logic controller (PLC). Immediate action was taken, and the 3rd launch was resumed just a day after the interruption. This event is regarded as an opportunity to enhance the ability to respond to technical errors that can occur during the launch process. This successful launch holds great significance as it marks the first instance of testing the practical purpose of Nuriho. In contrast to the 2nd launch last year, this time the launch vehicle successfully fulfilled its primary role of placing an actual satellite into the designated orbit, thus ensuring the reliability necessary to activate practical satellite integration and launch services in the future. The expansion of the government-led launch vehicle production and launch operation process into the private sector is also a significant achievement of the 3rd launch. In this 3rd launch, Hanwha Aerospace, the comprehensive system conglomerate for Nuriho's altitude increase project, participated in launch preparation and operations, acquiring the necessary technology to proceed with future Nuriho launches under private leadership. In the upcoming repeated launch processes, Hanwha Aerospace will continue to acquire launch operation-related technology. Starting from the 6th launch, Hanwha Aerospace will take the lead, excluding certain consoles such as the Launch Director (LD), Mission Director (MD), and Launch Control Center (LCC). The successful launch of Nuriho holds additional significance as it paves the way for validating domestic core technology capabilities through future space environment missions, including Next-Generation Small Satellite 2, in the target orbit. Minister Lee Jong-ho of the Ministry of Science, ICT, and Future Planning is conducting a briefing after the 3rd launch of Nuriho on the 25th. This recent success is expected to provide momentum for the development of the next-generation launch vehicle, aiming to dramatically enhance the nation's space transportation capabilities. The next-generation launch vehicle will incorporate reusable launch vehicle technology and feature a staged combustion cycle engine. The goal is to utilize the next-generation launch vehicle for national satellite and space exploration launch demands, with three launches planned by 2032. The 2nd and 3rd launches are scheduled to perform lunar lander launch missions. Minister Lee Jong-ho of the Ministry of Science and ICT stated, "By conducting three repeated launches of Nuriho by 2027 and concurrently pursuing the development of a next-generation launch vehicle with improved performance compared to Nuriho, we will secure international competitiveness. We will also establish a foundation to enable companies and research institutions to unfold new business models." 🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀 All right reserved : https://n.news.naver.com/article/030/0003102490?cds=news_media_pc&type=editn 누리호 3차 발사 최종 성공 ‘실용위성 발사체’ 입증한국형발사체 누리호가 실용위성 발사체로서 능력을 입증했다. 3차 발사 성공으로 발사체 기술에 대한 신뢰성과 안전성을 확보함은 물론 체계종합기업 첫 참여를 통해 민간이 주도하는 우주 생n.news.naver.com
