Korean domestic launch vehicle failed to fly into orbit for the first time. The "World" launch vehicle is the first launch vehicle independently developed by South Korea, with a total length of 47.2 meters and a weight of 200 tons. Why did the Korean domestic launch vehicle fail to fly into orbit for the first time?
Korean domestic launch vehicle failed to fly into orbit for the first time111October 2 1 day. The first Korean domestic launch vehicle failed to launch, and a simulated satellite could not be put into orbit.
Local time: 202 1,10,21,Happiness County, Korea. The South Korean launch vehicle "Nuri" was launched that afternoon. People's visual map Local time 17, the three-stage rocket Nuri (KSLV-II) was launched from the Luo Lao Space Center in South Korea. According to Yonhap News Agency, the rocket was successfully separated from the satellite at 15 17 in a 700km sun-synchronous orbit. However, data analysis shows that the third stage engine stopped working ahead of schedule, which made it impossible to send the satellite into the scheduled orbit. South Korean President Moon Jae in watched the launch at the scene and said that the rocket had completed all flight procedures, but failed to put the test load into orbit. "Unfortunately, we didn't fully achieve our goal."
Moon Jae in said that the project will continue to advance. Reuters reported that Moon Jae in said in a written record that "the Korean space age is coming" and "it won't be long before we can accurately launch it into the target orbit."
The Korea Aerospace Research Institute (KARI) said that five more test launches are planned before the rocket normally carries the real payload. The Nuri rocket is 47.2 meters long, weighs 200 tons, and has an orbital carrying capacity of 600-800 kilometers 1.5 tons. It is powered by a liquid fuel booster. According to the Korea Herald, the Nuri rocket carries South Korea's ambition to join the global space race. If the launch is successful, it means that South Korea has become the seventh country in the world that can independently launch satellites with a capacity of 1 ton or more from its own land into orbit.
The Korea Herald reported that South Korea has invested about 2 trillion won (about RMB 654.38+009 billion) to build its own launch vehicle. In the Nuri project, South Korea manufactured about 370,000 parts, completed 184 engine tests, and 300 local companies participated.
According to Reuters, South Korean officials have also said that having their own launch vehicle will enable South Korea to flexibly determine the payload type and launch schedule, which will also benefit Korean enterprises.
Before the Nuri rocket, South Korea's first launch vehicle "NARO" (KSLV-I) was launched in 2009, but the second separation was later than the scheduled design, which failed to send the scientific and technological satellites on board into the scheduled orbit. After two failed launches, Lao Luo was successfully launched in 20 13, and South Korea became the first country in the world to put a satellite into orbit.
However, the first stage of the two-stage rocket "Ronald" is made in Russia, and the second stage rocket is a solid fuel rocket made in South Korea.
Korean domestic launch vehicle failed to fly into orbit for the first time. At 2 1 day 17 local time, the launch vehicle "World" (KSLV-II) independently developed by South Korea was ignited and launched at the Luolao Space Center in Gaoxing County, Jeollanam-do. The rocket completed all flight procedures normally, but failed to send the model satellite into the scheduled orbit.
The "World" launch vehicle is the first launch vehicle independently developed by South Korea, with a total length of 47.2 meters and a weight of 200 tons. The rocket lifted off smoothly, the first and second stages were separated normally, and the fairing was also separated normally, but the third-stage engine stopped working ahead of schedule. Although the model satellite was successfully released at an altitude of 700 kilometers, it failed to enter the scheduled orbit because it failed to reach the flight speed of 7.5 kilometers per second.
The Ministry of Science, Technology, Information and Communication of Korea plans to set up a launch investigation committee to find out the specific reasons for the early stop of the third-stage engine and come up with an optimization plan to prepare for the second launch. It is reported that the second launch of the "World" carrier rocket is tentatively scheduled for May next year 19.
On the same day, South Korean President Moon Jae in observed the launch process at the Lao Space Center and delivered a speech, saying that although he regretted that he could not achieve the set goal perfectly, he was still proud of the great achievements made in the launch. If we can repeatedly check and improve the shortcomings, the second launch in May next year will be a success.
Moon Jae in also said that the South Korean government will unswervingly continue to invest in the long term and will continue to launch five world launch vehicles by 2027. At the same time, it will boldly challenge space exploration and strive to realize the dream of landing on the moon by using domestic launch vehicles before 2030.
