Nuri set to launch 15 satellites on the 7th, its most in one flight
In short
South Korea's Nuri launch vehicle is scheduled to fly for the fifth time on the 7th from the Naro Space Center in Goheung, South Jeolla Province, carrying 15 satellites — the most in a single Nuri launch. Five ultra-small cluster satellites, NEONSAT 2-6 developed under KAIST's Satellite Research Institute, are to be released at intervals of about 35 to 40 seconds, followed by 10 cube satellites launched in pairs. The five cluster satellites are expected to take about two to three months to settle into a formation spaced roughly 71 degrees apart in the same orbital plane.
Why it matters
The flight tests whether Nuri can deliver many satellites to their target orbits in sequence, an ability the Korea AeroSpace Administration said would raise the vehicle's mission capability by a step. Asia Economy reported that private-sector involvement in the launch has grown and that launch safety standards have become tighter, while Newsis framed the mission as a testbed for a private rocket.
Key facts
- Nuri's fifth flight is to carry 15 satellites, the most in a single launch for the vehicle, with lift-off set for the 7th from the Naro Space Center in Goheung, South Jeolla Province. [ 1 , 2 , 3 , 4 ]
- The main payload is five ultra-small cluster satellites, NEONSAT 2-6, developed under the direction of KAIST's Satellite Research Institute. [ 1 ]
- Ten cube satellites will also be aboard, including the domestically produced component and parts space-verification platform E3 Tester-2. [ 1 ]
- The five NEONSAT satellites are to be separated one at a time at intervals of about 35 to 40 seconds, after which the 10 cube satellites will be ejected in pairs at 10-second intervals and the third stage will perform an avoidance manoeuvre. [ 1 , 4 ]
- Chosun Ilbo reported the satellites are to be inserted at an altitude of about 575 km. [ 4 ]
- KAIST project head Lee Sang-hyun said the five cluster satellites would use thrusters and relative velocity to widen their spacing and match altitudes, taking about two to three months to form a formation spaced roughly 71 degrees apart in the same orbital plane. [ 1 ]
- Asia Economy reported that NEONSAT uses a mass-production approach, cutting production time per satellite from two to three years to about two months. [ 1 ]
- KARI said it developed a low-impact satellite separation device for the cluster satellites and applied a new lower ring to carry sub-payload satellites. [ 1 ]
Confirmed by several sources
- The fifth Nuri flight is to carry 15 satellites. [ 1 , 2 , 3 , 4 ]
- Five ultra-small cluster satellites are to be released at intervals of about 35 to 40 seconds. [ 1 , 4 ]
- The launch is scheduled for the 7th. [ 2 , 4 ]
- The launch site is the Naro Space Center in Goheung, South Jeolla Province. [ 1 , 4 ]
- Coverage describes the flight as involving a larger private-sector role and stricter launch safety standards. [ 2 , 3 ]
Still unclear
- Whether the launch falls in October or November 2026. An Asia Economy piece published on 4 October referred to the launch as being on 'next month's' 7th, while a follow-up piece from the same outlet and Chosun Ilbo, both published on 5 October, called it 'the coming 7th'; the documents do not resolve the discrepancy.
- The time of day of the launch. The documents give the date but no lift-off time.
- What the expanded private-sector role consists of. Asia Economy and Newsis say the private role has grown and that the flight is a testbed for a 'private rocket', but neither identifies the company involved or which parts of the launch are private.
- The full remarks of Korea AeroSpace Administration chief Oh Tae-seok on launching various satellites to various altitudes. The available article text is cut off mid-sentence, so his comments at the 30th debate cannot be reported in full.
What local media are saying
Business mediaThe business outlets treat the launch as a technical and industrial milestone: Asia Economy runs a three-part series detailing the 35-40 second separation intervals, the low-impact separation device, the two-to-three-month formation process, mass production of the satellites and a more crowded orbital environment; Chosun Ilbo highlights the record 15 satellites and the precise orbital insertion at about 575 km; Newsis frames the flight as a testbed for a private rocket. All emphasise the difficulty of releasing many satellites without collisions and the KASA expectation that the mission raises Nuri's capability.

Timeline, local time
- 4 October: Asia Economy publishes the second part of its Nuri series, describing the plan to release 15 satellites one by one at set intervals and the new separation hardware. [ 1 ]
- 5 October: Asia Economy's third part reports that near-Earth space is becoming crowded, so launches must take orbital 'traffic' into account, and that private-sector involvement and safety standards have grown; Newsis publishes the first part of its series, calling the flight a testbed for a private rocket. [ 2 , 3 ]
- 5 October: Chosun Ilbo reports that the launch is scheduled for the 7th from the Naro Space Center in Goheung, with the five cluster satellites to be released at 35-40 second intervals after the rocket reaches about 575 km. [ 4 ]
