Japan has taken a crucial step to spy on North Korea. A surveillance satellite was launched into orbit on Friday. It will detect the movements of North Korean forces. It also provides early detection and warning of threats in the environment. It was launched by an H2A rocket from the Tanegashima space station. This satellite can take clear images. In 1988, a North Korean missile flew over Japan. Since then, Japan has taken steps to develop its own surveillance satellite network. It aims to establish a network of 10 satellites. Japan will get a chance to quickly detect missile launches with the help of this network. On the other hand, the H3 rocket is also being developed to speed up space missions.
