South Korea’s Nuri rocket launches with 15 satellites
En breve
South Korea’s Nuri rocket lifted off from the Naro space centre at 12:25 local time on 7 October and placed 15 satellites in orbit, including five Neonsat remote-sensing craft and 10 cubesats, KARI said. KASA director Oh Tae-seok said stage and fairing separations went according to plan. It was the fifth flight of Nuri, the country’s first fully domestically developed launch vehicle.
Por qué importa
The launch is the largest satellite payload South Korea has placed in orbit and, according to Kommersant, shifts the Nuri programme from demonstrating the rocket to using it to deploy the country’s own observation constellation. The Neonsat craft are described as serving disaster response and national security, giving South Korea an independent source of imagery over the Korean peninsula. Because the coverage comes mainly from official and business outlets reporting a national space milestone, its wider relevance is limited to space and defence-sector readers.
Datos clave

- It carried 15 satellites: 10 cubesats or microsatellites and five Neonsat craft weighing less than 100 kg each. [ 2 , 5 , 7 ]
- KARI said all satellites were placed in the target orbit, and KASA director Oh Tae-seok said stage and fairing separations went as planned. [ 2 , 4 , 5 , 6 , 7 ]
- The Neonsat satellites are intended for remote sensing of the Korean peninsula, rapid response to natural disasters and national security tasks. [ 1 , 2 , 5 , 7 ]
- It was the fifth launch of Nuri since 2021. [ 2 , 7 ]
- Kommersant reported that Nuri is South Korea’s first launch vehicle developed entirely on its own, after the earlier Naro-1 built jointly with Russia. [ 7 ]
- The Neonsat constellation is to total 10 satellites. [ 2 , 7 ]

Aún sin aclarar
- The iXBT headline said “9 of 10” Korean satellites reached orbit, while the same outlet’s summary and the other documents reported the launch as successful with all satellites deployed. A conflict between headline and text within one outlet; no other document supports a partial deployment failure.
- The target orbit altitude is given as 575 km by Vedomosti and about 570 km by iXBT. The two outlets state slightly different figures.
- The completion of satellite deployment is given as 12:42 local time by Vedomosti and as about 20 minutes after launch by Kommersant. The outlets give different timings for the end of deployment.
- The schedule for the remaining five Neonsat satellites is given as next year by iXBT and as by the end of the space programme in 2027 by Kommersant. The outlets disagree on the timeframe.
