Successful launch of Nuri made Korea
"World seventh Space Powerhouse"
The South Korean launch vehicle, the Nuri (KSLV-II), was successfully launched.
Minister of Science and ICT Lee Jong-ho officially confirmed on the 21st that the Korean projectile Nuri (KSLV-II) was successfully launched and landed the satellite in the planned orbit.
The Nuri rocket was launched at 4 p.m. and successfully separated.Accordingly, the Nuri satellite and the performance verification satellite are circulating around the Earth at an altitude of about 700 kilometers from the surface and at a speed of about 7.5 kilometers per second.
Minister Lee held a briefing at the press center of the Naro Space Center in Goheung-gun, Jeollanam-do, and said, "Today, I stood at a monumental moment in Korea's history as well as Korean science and technology history."
"The Nuri, which was launched at 4 p.m. today, was put into target orbit, successfully separated the performance verification satellite and settled in orbit""We announce the success of the Nuri, a Korean-style projectile."
Minister Lee then said, "The sky of Korea has opened wide. South Korea's science and technology has made great progress."
With the successful launch of the Nuri, South Korea has become the world's seventh space powerhouse to launch a practical satellite of more than one ton into a space launch vehicle with its own technology.
Nuri is the first space launch vehicle designed and developed with pure domestic technology. South Korean researchers have developed 75-tonand 7-ton liquid fuel engines that launched satellites, as well as pairing, a cover that protects satellites mounted on projectiles.
In particular, analysts say that it has successfully demonstrated the performance of 75-ton engines that can be used continuously for the development of large and small projectiles in the future, creating a foothold for future space development
Earlier, Nuri's first-stage separation, pairing separation, and second-stage separation were normal at the time of the first launch on October 21 last year, but failed to settle the satellite mimic in low orbit as the third-stage engine ended early combustion.
After scrutinizing the problems of the three-stage rocket identified in the first launch, the Korea Aerospace Research Institute took technical improvement measures in the second launch and led the launch to a success.
