According to CCTV news, on the afternoon of the 21st local time, South Korea’s self-developed rocket “World” was fired again at the Rao Cosmos Center in South Jeollanam-do, South Korea.The South Korean government later announced that the rocket was successfully launched.
The “World” launched this time is equipped with artificial satellites, and the purpose of the launch is to accurately put the satellites into orbit.
“World” had its first launch on October 21, 2021, but after the launch, the third-stage engine stalled earlier than expected.The launch failed to successfully put the mock satellite into its intended orbit.
The second launch was originally scheduled to take place on June 15 this year, but the launch date was then delayed by one day to the 16th due to weather. After that, sensor abnormalities were found during the launch preparation process, and the launch was postponed again to today.
It is understood that the “World” is the first rocket developed entirely using South Korean technology.The whole project took about 12 years and the total investment was nearly 2 trillion won (about 10.4 billion yuan).
The media previously reported that before the “World” rocket, South Korea’s first launch vehicle “Ra Lao” was launched in 2009, but the second separation was later than the scheduled design, and the scientific and technological satellites it carried were not able to be put into the intended orbit. .
After two failed launches,In 2013, the “Rao” was successfully launched, and South Korea became the 11th country in the world to put a satellite into orbit.
However, the first stage of the two-stage rocket “Luo Lao” is made by Russia, and the second stage rocket is a solid-fuel rocket made by South Korea.
