The launch management committee is scheduled to be held on the evening of the previous day and in the afternoon of the same day before the launch on the 21st.
Additional experiments are planned in the future to determine the cause of the part abnormality found on the 15th
(Naro Space Center[고흥]·Seoul) Reporters Dayoung Moon and Gyujin Oh = Preparations on the eve of the launch of the Nuri, scheduled to be launched on the 21st, were completed smoothly as scheduled.
The Ministry of Science and ICT (Ministry of Science and Technology) and the Korea Aerospace Research Institute (Aviation Research Institute) announced on the 20th, “The installation of the Nuri launch pad was completed around 6:37 pm.”
Earlier, Oh Seung-hyeop, head of the projectile propulsion engine development department of the Korea Air Defense Association, held a briefing on the preparation status of the Nuri at the Naro Space Center at 3:30 pm on the same day.
According to Director Oh, the Nuri departed from the launch vehicle assembly building in the Naro Space Center in Goheung-gun, Jeollanam-do at 7:20 am on the same day and arrived at the launch pad at 8:40 am.
After preparation work before standing up, Naro started to stand at 9:56 a.m. and was completely fixed to the launch pad at 11:10 a.m.
The anti-accidental agency conducted an electrical inspection of the projectile from 12:22 to 56 pm.
Director Oh said, “(Last 15th), except for the level sensor part (of the first stage oxidizer tank) that was problematic, all parts (checks) were performed normally.”
From 2:45 p.m., the anti-accidental engineering team began to connect the hydraulic and pneumatic umbilicals.
After that, the technical team finished all the work that had to be done that day, the Ministry of Science and ICT said, after completing the confidentiality check, which is a task to determine if there is a possibility of clogging or leaking while charging fuel or oxidizer.
Whether to continue preparatory work on the morning of the 21st, the scheduled launch date, will be decided at a meeting of the Nuri launch management committee chaired by Oh Tae-seok, 1st Vice Minister of Science, Technology and Information and Communication (Ministry of Science and Technology) on the evening of the 20th.
If the work goes as scheduled on the 21st, the process of re-checking the already connected umbilical facilities and injecting helium gas from 10 am will continue.
The Ministry of Science and ICT will hold the launch management committee again on the afternoon of the 21st to comprehensively review the technical preparation status, weather conditions, and the possibility of colliding with space objects to determine the launch time of the Nuri.
Currently, the most likely launch time is at 4 pm on the 21st, said Director Oh.
Director Oh said that he plans to reveal the reason for the problem through additional tests on the abnormality of the first stage oxidizer tank level sensor discovered on the 15th.
He said, “Since Nuri has independently designed, manufactured, and tested all the systems for the 1st, 2nd, and 3rd stages, even if there is a problem, we know who is in charge of how to solve it,” he said. revealed
Regarding the level sensor problem, he said, “It is predicted to be an error that occurs frequently in the process of commercial operation and launch in advanced countries. said
Director Oh concluded the briefing on the afternoon of the 20th, vowing, “Until the end, the tension is not good and the launch of the Nuri will be successful, and the Republic of Korea will open the way to space.”
