[Nuriho 4th Launch] Fourth Rocket Begins Transfer to Launch Pad... Full-Scale Erection and Umbilical Connection Underway

The fourth Nuri, a Korean launch vehicle, began full-scale launch preparations on the morning of November 25 by being moved to the launch pad at Naro Space Center in Goheung, Jeollanam-do. The Korea Aerospace Administration and the Korea Aerospace Research Institute announced that the transfer of Nuriho began at 9 a.m. that day.

The originally scheduled transfer time to the launch pad was 7:40 a.m., but as rain was forecasted around 8 a.m., the launch preparation committee reviewed the weather information again and delayed the transfer by about one hour and twenty minutes. After a meeting at 8:30 a.m., the final decision was made to begin the transfer at 9 a.m.

Nuriho is loaded onto an unmanned special transporter and slowly moves from the main assembly building to the second launch pad, a process that takes about one hour and ten minutes. After arriving at the launch pad, preparations for erecting the rocket will take place, followed by the process of raising it to a vertical position.

In the afternoon, key preparations will be carried out, including connecting the umbilical for power supply and propellant (fuel and oxidizer) loading, as well as various airtightness checks. The Korea Aerospace Research Institute stated, "If there are no issues during the transfer, erection, and umbilical connection processes, installation work on the launch pad is expected to continue until late tonight," adding, "The schedule may be adjusted depending on weather conditions."

If all work is not completed on the same day, additional tasks will be carried out the following morning to ensure that the launch operation schedule is not affected. Since the launch is scheduled for the early morning of the 27th, there is sufficient time in the schedule.

The Korea Aerospace Administration will convene the 'Nuriho Launch Management Committee' on the afternoon of the 26th to give final approval for propellant loading. In addition, the committee will comprehensively review the technical readiness, launch window, weather conditions, and the possibility of collision with space objects to determine the final launch time.
