In a briefing on the 29th, Lee Chang-yoon, the Ministry of Science, ICT and ICT, announced the details confirmed by the 18th National Space Commission. Korean pitcher ‘Nuri’ will be released for the first time in October next year, which is delayed eight months from the plan.

The native launch vehicle ‘Nuri’, which is being developed with Korea’s own technology, will be launched for the first time in October next year, eight months behind the original plan. The ‘Cheonrian 3’, a satellite in geostationary orbit that will monitor disasters, will begin development next year and will be launched in 2027. The Ministry of Science and ICT held the XVIII National Space Committee and confirmed the details. The National Space Commission was held in writing on the 22nd and 28th of this month.
The first launch of the Nuri was planned to be launched in February next year and the second launch in October, but according to the opinions of experts that more time is required to verify the technology of the complicated launch vehicle, the first launch will be in October next year and the second release will be Each postponed to May 2022.
As a result of a thorough inspection of the development situation of Lake Nuri for approximately 3 months starting in September, Nuriho’s assessment team, consisting of 15 experts from industry, academia and research centers, joined four engines 75t class for the first stage of the Nouriho to produce 300t (ton) of thrust. Four months were delayed in the grouping work and two more months were determined since the delivery of spare parts for the first stage was delayed.
In addition, it was decided to load and discharge oxidizing agent (liquid oxygen) to the projectile before launching the Nuri, and to carry out the final ground test (WDR), which finally confirms the stability of the projectile, adding two months, requiring a total of eight months for launch. Completed.
Jeong-hwan Jeong, director of the Korea Aerospace Research Institute, director of the Korea Aerospace Research Institute, which oversees the development of the Nuri, “The first stage of the Nuri contains four engines and consequently took longer to assemble and disassemble. in the process of connecting more than 1,000 pipes “. Explained.
The three-stage Nuri completed production of a three-stage flight model equipped with a 7t-class engine in November this year, and is currently in the process of assembling the first and second-stage flight models. In January next year, it plans to conduct a comprehensive combustion test with four grouped 75t-class engines using a certified model.
Lee Chang-yoon, Ministry of Science and ICT, said: “The Nuri has been developing independently for the first time in Korea since 2010, and many researchers have solved the technical difficulties. The government will actively support the development of the Nuri.” said.
On the other hand, the ‘Cheonrian 3’ public geostationary orbit multi-communications satellite, which will monitor disasters, will be launched in 2027 after investing 41.82 billion won over 7 years starting next year. The Cheonrian 3 serves as a test bed for future satellite communications technology by providing satellite positioning system (GPS) position correction signals, as well as flood disaster monitoring, support for maritime activities and emergency communications in disaster areas.
To this end, Cheonrian No. 3 carries the electric propulsion system and high-performance satellite navigation system (GNSS) receiver of Cheonrian No. 2A and 2B, and three types of communication vehicles are also charged as communication broadband, information gathering and correction of satellite navigation.
