South Korea's first domestically produced launch vehicle is scheduled to challenge the second launch on June 21.
According to Yonhap News Agency, the Ministry of Science, Technology, Information and Communications of South Korea said on June 17 that it will hold a meeting of the launch management committee to promote the second launch of the self-developed launch vehicle "World" (KSLV-II) on the 21st.
South Korea's first domestically produced carrier rocket "World" was originally planned to be launched on the 16th, but after it was transferred to the launch pad on the 15th, it was found that the data of the inclination sensor inside the "World" oxidant tank was abnormal.
The Korea Institute of Aeronautics and Astronautics said on the 15th that the sensor is a device that measures the amount of oxidant injected into the oxidant tank. When the rocket body was erected on the launch pad, the sensor data should change with the movement of the rocket body, but the data remained unchanged, so it was considered abnormal.
Since the part where the abnormality occurred was difficult to access, it was checked as soon as possible, and the arrow body was re-transported to the assembly room. According to Yonhap News Agency, South Korea originally judged that the sensor can only be replaced by separating the first-stage and second-stage rockets, but after a close inspection, it was found that only the core parts need to be replaced. On the morning of the 17th, the faulty electrical parts of the sensor were replaced. The "World" will be transported to the launch pad on the 20th and is planned to be launched on the 21st.
This will also be the second launch attempt of the "World" rocket. World's first launch failed last October, failing to put a 1.5-ton mock satellite into orbit. At that time, the three-stage rocket "World" was launched from the Naro Aerospace Center in South Korea and successfully separated from the satellite in a 700-kilometer sun-synchronous orbit. But data analysis showed that the third-stage engine stopped working prematurely, causing it to fail to put the satellite into its intended orbit.
