South Korea Prepares Nuri Rocket for Fifth Flight Carrying Record 15 Satellites

Liftoff Scheduled Within Midday Window

South Korea’s homegrown Nuri space launch vehicle is positioned for its fifth flight on October 7, 2026, carrying a record payload of 15 satellites from the Naro Space Center in Goheung, South Jeolla Province.

According to the Korea AeroSpace Administration (KASA), a launch management committee is scheduled to convene to review technical readiness, meteorological conditions, and space debris collision risks before giving final clearance for propellant loading and confirming the exact liftoff time. The provisional launch window is set between 12:23 p.m. and 1:23 p.m. Korea Standard Time.

The 47.2-meter rocket was transported to the second launch pad on October 6 using an unmanned special transport vehicle, completing the 1.8-kilometer journey from the assembly complex in roughly 90 minutes. Ground teams subsequently raised the vehicle into a vertical position, secured it to the pad, and completed umbilical connections and leakage inspections.

Payload Details and Mission Objectives

The fifth flight features the heaviest total payload mass for the Nuri vehicle to date, weighing approximately 1,071 kilograms and targeting a sun-synchronous orbit at an altitude of roughly 570 kilometers. The manifest includes:

Five NEONSAT Microsatellites: Built by Satrec Initiative under the oversight of KAIST’s Satellite Technology Research Center, these Earth-observation spacecraft represent the second through sixth units of a planned 10-satellite constellation intended for disaster response and national security monitoring.
Ten CubeSats: Developed by domestic companies, universities, and research organizations to test experimental technologies, including low-cost commercial electronics protection in low Earth orbit.

This mission marks the first time Nuri will sequentially deploy multiple primary satellites supporting the same constellation program. The primary microsatellites are scheduled to separate at intervals of 35 to 40 seconds utilizing a newly introduced low-shock separation system, followed by the secondary CubeSats deployed in pairs.

Private Sector Integration

The launch represents a significant operational transition for South Korea's aerospace sector. While the Korea Aerospace Research Institute (KARI) previously managed hands-on console operations directly through past missions, Hanwha Aerospace—acting as the system integration partner—has assumed a leading role for the fifth flight. Private-sector personnel are operating the majority of the launch control consoles as part of a phased plan to transfer complete launch vehicle assembly and execution capabilities to private industry.

Developed entirely with domestic technology, the three-stage Nuri rocket previously achieved successful back-to-back orbital insertions following its initial test flight in 2021, establishing South Korea's independent access to space.
