(Seoul = Yonhap News) Reporter Dayoung Moon = The Korea Aerospace Research Institute (KAI) announced on the 19th that it would transfer the Korean launch vehicle Nuri (KSLV-II) to the launch pad on the 20th.

The anti-accidental technical team held a flight test committee on the afternoon of the 19th to discuss the possibility of rolling out the Nuri (the process in which the projectile comes out of the assembly building) and made this decision.

Accordingly, the Nuri will depart from the projectile assembly building at 7:20 am on the 20th and move to the launch pad.

So far, no weather conditions have been found to affect launch preparations.

According to an official from the Korea Meteorological Administration, on the 20th, the ground wind at the Naro Space Center in Goheung-gun, Jeollanam-do was expected to be 1-3 m/s, and no precipitation was predicted.

It is expected that winds of 5 m/s will blow at the altitude where the 47.2 m long Nuriho is erected and fixed to the 48 m high umbilical tower.

Previously, the Ministry of Science and ICT (Ministry of Science and ICT) and the Korea Air Force postponed all launch preparation schedules by one day, judging that it was difficult to secure the safety of the technicians due to strong winds on the 14th, one day before the scheduled launch date.

As a result, the Ministry of Science and ICT and Korea Institute of Science and Technology, who postponed the launch date to the 16th, completed the transfer of the Nuri to the launch pad on the 15th, but found a problem with the level sensor signal in the first stage oxidizer tank. and replacement of parts.

The new scheduled launch date is the 21st, and the launch time is likely to be 4:00 pm, but it is flexible.

This is the second attempt to launch the Nuri. The first launch on October 21 last year succeeded in reaching an altitude of 700 km, but the third stage engine burned prematurely, and the final goal of placing a 1.5 t mass satellite in the target orbit was not achieved.
