　　According to reports, the Ministry of Science, Technology, Information and Communications of Korea and the Korea Aerospace Research Institute said on the 14th that strong winds occurred at the Nalao Aerospace Center in Heung-gun, Jeollanam-do, and the wind may further increase after that, making it difficult to fully ensure the safety of the launch pad technicians.

Therefore, the transfer and launch of the rocket will be postponed by one day to the 15th and 16th, respectively.

　　The report pointed out that the Korean Aerospace Research Institute held a meeting of the flight test committee on the morning of the 14th to evaluate whether it has the conditions for a transfer rocket.

The weather forecast shows that there will be rain and strong winds in Xinghe County that day. The working group believes that there may be safety problems when fixing the rocket and the umbilical tower, and the transfer vehicle may slip on the uphill section.

　　As previously reported, on October 21, 2021, the "World" carrier rocket was ignited and launched.

The rocket completed all flight procedures normally, but failed to send the model satellite it carried into the intended orbit.

The Korean Ministry of Science, Technology, Information and Communications and the Institute of Aeronautics and Astronautics announced the results of the investigation, which showed that the helium tank fell off mainly because the fixing device inside the rocket's third-stage engine was loosened.

　　"World" is a three-stage launch vehicle with a total weight of 200 tons, which can send 1.5-ton satellites to orbits 600 to 800 kilometers above the ground.
