– Final Pre-Launch Test Conducted for Nuri’s Fourth Launch Scheduled in November
– KASA Administrator Visits Naro Space Center in Goheung to Encourage Luanch Staff
On September 16 (Tuesday), Yoon Youngbin, Administrator of the Korea AeroSpace Administration (KASA), visited the Naro Space Center in Goheung, Jeollanam-do to inspect preparations for the fourth launch of the Nuri rocket. The visit was intended to check the final pre-launch test, known as the Wet Dress Rehearsal (WDR), and to encourage researchers from the Korea Aerospace Research Institute (KARI) and industry partners.
The WDR is a critical test in which the launch vehicle is erected on the launch pad, the connections between the vehicle and the pad are verified, and liquid oxidizer is loaded at cryogenic temperatures of -183℃ following the actual launch sequence. The purpose is to confirm the readiness and integrity of the launch vehicle prior to launch.
The WDR schedule began on September 16 with the erection of the rocket, followed by oxidizer loading and unloading on the 17th, and transfer of the vehicle back to the assembly building from the launch pad on the 18th. Analyzing the WDR results will take about a week, and if no issues are found, satellite integration will proceed, with the launch targeted for November.
During the visit, Administrator Yoon received a briefing on Nuri’s fourth launch preparations, observed the rocket erection and connection process at the pad, and encouraged researchers and staff on site.
Administrator Yoon emphasized, “This launch marks the first jointly conducted by KARI and Hanwha Aerospace, and it represents the first step toward a transition to private-sector leadership.” He added, “I thank all those who are working tirelessly for the success of Nuri’s fourth launch. Through this test, I urge you to thoroughly verify launch readiness and ensure flawless preparation in the time remaining.” He further stated, “KASA will continue to secure sustainable space transportation capabilities and provide support so that companies can take the lead in building an industrial ecosystem.”
