As the Russo-Japanese War and the Li-Xia War demonstrate, influence in space is increasingly being exercised militarily rather than peacefully. In the era of Newspace, not only states but also private companies have emerged as actors in space warfare. Although international law stipulates that outer space is to be used for peaceful purposes, it is imperative for the survival and prosperity of the nation to establish a national security policy regarding the dangers and threats that arise from outer space, as military use is clear. Threats that may occur in the space domain can be divided into kinetic and non-kinetic threats. Kinetic threats include anti-satellite missiles, collisions between space satellites and debris, and laser attack weapons. Non-kinetic threats include electronic and cyberattacks, and space radiation. A space strategy that is harmonious and balanced is needed to avoid imbalances in policies to respond to risks and threats in space. From a national security perspective, it was suggested to develop independent space assets, expand space assets to the private sector, and prepare for space wars.

In recent years, the space sector has been changing rapidly. The militarization of outer space is openly underway. On the other hand, space commercialization by private capital called "Newspace" is emerging in the U.S. Additionally, the Artemis project, a manned space moon exploration project, is being resumed 50 years after the end of the Apollo program. Eventually, the commercial use of space resources is actively being discussed. Due to the rapidly developing space technologies, the U.N. Space Treaty, enacted in 1967, has established the norms and principles of space activities. However, it may be nearing the end of its life. To confront the challenges of a new space era, Korea must engage in various legal and policy studies to meet these changes.

Active debris removal, a technology that approaches and removes space debris in orbit, and the on-orbit service, a technology for extending the mission life of satellites by fuel charging or by exchanging the battery, are gaining interest with the growth of the space community. SaTReC plans to develop a satellite capable of capturing and removing Korean satellites orbiting in space after the end of their missions. In contrast to the previously launched satellites by Korea, which were mainly intended to observe Earth and the space environment, rendezvous/docking technologies, as required in the future during, for instance, space exploration missions, will be implemented and demonstrated. In this paper, an orbital transition method for next-generation small satellites that will capture and remove space debris will be introduced. It is assumed that a small satellite with a mass of approximately 200 kg will be injected into the mission orbit through Korea Space Launch Vehicle-II in 2027. Because the satellite must access the target using a minimum amount of fuel, an approaching technology using Earth's J2 perturbation force has been developed. This method is expected to enable space debris removal missions for relatively lightweight satellites and to serve as the basis for carrying out a new type of space exploration in what is termed the 'Newspace' era.
