After entering the lunar orbit in January next year, kplo will conduct various scientific experiments for one year < p > the South Korean military signed a contract with SpaceX last year to launch five reconnaissance satellites continuously by the end of 2025. In July 2020, the first communication satellite named ANSIS II of the South Korean military was launched by Falcon 9 < p > based on the expectation that more reliance on SpaceX will increase the cost of South Korea's space exploration project, domestic experts call for accelerating the pace of independent research and development of rockets < p > other experts also warned that as more and more countries want to use SpaceX rockets instead of Russian rockets, South Korea will face setbacks in launching satellites at an appropriate time. It is said that the SpaceX rocket launch plan for the next 18 months has been fully booked. (small) < / P > < p >
