South Korea's domestically developed rocket has been able to place satellites in orbit in the second attempt.
“Nuri” or KSLV-II – launched from the Naro Space Center located in the southern province of Jeonnam – “successfully” separated and placed a “performance verification” satellite at the targeted orbit, Lee Jong-ho, South Korea's Minister of Science and ICT (information and communications technology), said at a media briefing.
The South Korean government “plans to enhance technical reliability and stability of Nuri through four rounds of additional launchings until 2027”, Jong-ho added.
According to local media reports, the Ministry of Science and ICT confirmed on 22 June that the performance verification satellite has established communication with the state-run Korea Aerospace Research Institute's (KARI's) ground station located in the city of Daejeon.
The ministry has also said that, from 29 June the performance verification satellite will release four cube-shaped satellites – one after the other with a two day interval between each release – to conduct various observational missions.
According to KARI, Nuri is a three-stage rocket with a length of 47.2 m and a weight of 200,000 kg. The rocket can carry a 1.5 ton application satellite into a 600–800 km solar synchronous orbit.
Nuri is powered by four liquid-propellant 75-ton engines in the first stage, another 75-ton engine in the second stage, and one seven-ton engine in the third stage.
