The second launch of the Korean projectile Nuri (KSLV-II) was postponed for one day on the 16th.
At the flight test committee meeting held at 6 am on the 14th, it was judged that the local weather conditions such as lightning strikes and rain were not good, and such a decision was made.
The Ministry of Science and ICT and the Korea Aerospace Research Institute (Korea Aerospace Research Institute) said this morning, “A strong wind is blowing at the Naro Space Center and it may become stronger in the future. I decided that it could be difficult. ” “We have decided to postpone the transfer and launch of the Nuri by one day from the original plan, transfer it on the 15th, and launch it on the 16th,” he explained.
Kouken initially planned to make a decision on the evening of the 13th whether to transfer the Nuri, which is about to be launched for the second time on the 15th, to the launch pad on the 14th as planned, but it is uncertain on the morning of the 14th. The decision was postponed due to the persistent weather conditions.
Prior to this, Kouken engineers will hold a flight test committee from around 5:30 pm on the 13th to decide whether to roll out the Nuri as scheduled on the 14th (move the projectile to the assembly building). Discussed.
The work to transfer the Nuri from the assembly building to the launch pad was planned from 7:20 am to 8:30 am on the 14th, but it was postponed to the same time on the 15th.
According to Kouken, in the case of ground wind, the average wind speed at launch is 15 meters per second, the maximum instantaneous wind speed is 21 meters or less per second, there should be no thunderstorm within a radius of 20 kilometers, and the temperature is 10 to 35 degrees below freezing. Must be between degrees.
The Kouken engineers said that the day before, it would rain in the Goheung area of Jeollanam-do and strong winds would be forecast, which could cause safety problems when fixing the Nuri to the umbilical tower. It was reported that he pointed out.
The umbilical tower plays the role of connecting propellants to the Nuri, but because of its height, it is dangerous for workers to climb up and perform the necessary work if strong winds blow.
