The First Korean-Type Launch Vehicle 'Nuriho' Stands on the Launch Pad for Final Inspection

[Asia Economy Reporter Kim Bong-su] The first Korean launch vehicle, Nuriho, scheduled to be launched into space on October 21, has been erected on the launch pad for final inspection.

The Ministry of Science and ICT announced on the afternoon of the 26th that the flight vehicle to be used for the actual launch was transported and erected on the launch pad for the final pre-launch inspection, the oxidizer loading and unloading test (WDR, Wet Dress Rehearsal).

WDR is the final inspection process of the launch vehicle before launch. It involves erecting the launch vehicle on the launch pad and charging and discharging the oxidizer at minus 183°C in an ultra-low temperature environment to verify the normal operation of the launch vehicle. To this end, the Korea Aerospace Research Institute transported and erected the flight model on the launch pad (Umbilical Tower) on this day. Afterwards, the system linkage status between the launch vehicle and the launch pad will be checked, and especially on the 27th, the oxidizer (liquid oxygen) at an ultra-low temperature of minus 183°C will be injected and discharged to check for any abnormalities. The analysis of the WDR results will be conducted for about one week, and if there are any corrective measures based on the analysis results, they will be addressed before proceeding with the launch procedure.
