Two consecutive failures! South Korea's self -developed Rocket "World" finally launched successfully

Science Fiction Network June 22 (Wang Ziyu) Recently, South Korea's first self -developed Rockets "World" was successfully launched. The simulation satellites have successfully entered the track. nation.

According to the Korean Daily, the "World" is a rocket independently developed by South Korea. The entire project lasted about 12 years, with a total investment of about 10.4 billion yuan. The entire rocket is about 46.5 meters long and the total weight is about 200 tons. The 1.5-ton satellite can be sent to the orbit 600-800 kilometers from the ground. It is understood that after 13 minutes of flight, this rocket can successfully send the satellite to the scheduled solar synchronization track.

At present, only Russia, the United States, the European Union, China, Japan, India, Israel, Iran, and North Korea with independent satellite launch capabilities, but only the top 6 countries that can launch more than 1 ton of satellites. With the success of the "World", South Korea has also become the seventh country in the world to launch more than one ton of satellites.

Of course, this is not the first launch of the "World". The first launch was originally scheduled to be held on October 21, 2021. However, due to the opening of the third -level engine in advance, the launch failed. The second launch plan was planned on June 15 this year, but due to the data abnormal data of the liquid oxygen storage tank and the windy weather, the second launch was postponed twice, and it was not successful until the third launch.

The successful launching task was successful. South Korean scientists believe that the overall performance of the "World" rocket has reached the level 1 of the Long March 1 rocket better than my country, which is lower than the level of the Long March 2 launch rocket. However, in fact, some domestic private space companies develop commercial rocket capacity than the 'World' rocket.
