South Korea's first privately-owned commercial launch rocket launch has been postponed to the 23rd.

South Korean space startup company INNOSPACE announced on the 21st that the carrier rocket "Kwang-NANO" developed by the company will be launched at 3:45 am on the 23rd at the Alcantara launch center in Brazil. The rocket was originally scheduled to launch on the 20th, but during the final filling stage of the propellant, an abnormality was found in the pressure relief valve of the methane tank of the second stage, causing the launch to be halted. This is the third time that the launch of the rocket has been delayed. INNOSPACE emptied the propellant after discovering the issue, placed the rocket horizontally on the launch pad, and conducted inspections. It was found that other components were normal except for the pressure relief valve, and there is a spare valve available for replacement.
