  • In this study, 10th grade students' views about the universe were surveyed and its affecting factors were investigated. Results showed that when hearing the word of 'the universe', 10th grade students considered it as 'a physical space'. Many students used 'feeling', or 'unknown space' to explain. When they portrayed the universe, many of them described it as a solar system scale. About the center and spatial limit of the universe, most students explained with the view of a heliocentric, geocentric or non-centered universe. Many students explained that the universe changed along with a direction as a physical space. These results were investigated again in different groups in terms of gender, beliefs, and familiarity with astronomy. As a result, students' models about the center, spatial limit, and the variation of the universe were different in the groups. Explanation of the origin of the universe was affected by the religious belief. Results showed that personal views of the universe are various, and many factors influence their views.

  • Space debris is the collection of objects in orbit around the Earth that were created by humans but no longer serve any useful purpose. Since the beginning of spacecraft launch in 1957, the number of space debris has been increasing. According to USSTRATCOM, the number of space debris which were bigger than 10 cm is more than 15,000. Recently there were two critical events: One is that China shot down their satellite using missile and the other is that two satellite, United States's Iridium 33 and Russia's Cosmos 2251, collided with each other. Thanks to these events, Space environment in which KOMPSAT-2 operates has become severer. This paper presents the analysis of the number of space debris which are close to KOMPSAT-2 and the maximum conjunction probability via minimum range. Especially, this paper makes it possible to continuously monitor the space debris that is possible to hit KOMPSAT-2 through the identification and analysis.

  • According to the dispostions of 1967 Space Treaty, the contracting states should assume legal obligation to assure an authorization and continuing supervision with regard to the national space activities. Any space activities have to abide by the rules of international law as well as specified obligations set by the Treaty. Among several treaty obligations, International responsibility to be bome by the state, and the liability principles are deemed as major outstanding obligations which the state should takeinto account. While nation's first launch site is to be operational in a few years, korean government should assure that its national space activities, such as launching of space object, operation of satellites, etc. should be under governmental authorization and supervision. A legislative effort would be most desirable undertaking for this regard. Especially a specific legislation needs tobe studied forwith such authorization regime so that international responsibilty and the liability as to thelaunching of space object should be under the regulatory scheme. This study focuses upon the necessity of such legislation and proposes some major items and framework for the legislation

  • In the sixty year since the first launch of Sputnik 1, it has become impossible to consider economic, political, or scientific human life in the communication field without reference to outer space. But, there is a growing groundswell of public opinion aimed at preventing arms race in space. Therefore it is necessary to establish some institution or mechanism such a code of conduct, international law. But every nation has a different posture on the grounds of national interest, or different levels of space development, the conditions required for the successful negotiation of a comprehensive treaty are not yet ripe. It is hoped that by beginning with soft measures (TCBM, Code of Conduct) for which it is easier to secure voluntary participation it may be possible to build up to a comprehensive treaty. The participation of the Space powers (US, Russia, China) in a dialogue of mutual exchange and shared information would contribute to international peace and give a long term benefit to humankind. It is also necessary to promote partnership through regional and bilateral cooperation. We should guide and shape opinion so that more nations ratify and sign existing international legal covenants in order to contribute to the efficency of Space law. International law needs to enforce PAROS and Space Security.

  • The idea of creating a new International Space Agency (ISA) is only my academic and practical opinion. It is necessary for us to establish ISA as an international organization for the efficient and rapid exploitation of natural resources in the moon, Mars and other celestial bodies. The establishment of ISA as a new international regime is based on the Article 11, 5 and Article 18 of the 1979 Moon Agreement. In order to establish as a preliminary procedure, it needs to make a "Draft for the Convention on the Establishment of an International Space Agency" among the space-faring countries. In this paper, I was examined the domestic space legislation in the United States, Luxembourg, European Space Agency, China, Japan, the Republic of Korea as well as space exploration and planning of the moons, Mars, Asteroids, Venus, Jupiter, Saturn, Titan and Other Celestial Bodies. The creation of an ISA would lead to a strengthening of the cooperation needed essentially by the developed countries towards joint and cooperative undertakings in space and would act as a catalyst for the space exploration and exploitation of the moon, Mars and other celestial bodies. It will be managed effectively and centrally the exploitation and exploitation of space the natural resources, technology, manpower and finances as an independent organization in order to get the benefit of the space developed countries by ISA. It is desirable and necessary for us to establish ISA in order to promote cooperation in space policy, law, science technology and industry among the space developed countries in the near future. The establishment of the ISA will be promoted the international cooperation among the space-faring countries in exploration and exploitations of the natural resources in the moon and other celestial bodies. I would propose the "Draft for the Convention for the Establishment of an International Space Agency." in refering the "Convention for the Establishment of a European Space Agency." This "Draft for the Convention Convention for the Establishment of an ISA" must pass the abovementioned "Draft for the Convention" by two-third majority of Diplomatic Conference in the UNCOPUOS. Finally, a very important point is need that a political drive at the highest level and a solemn statement by heads of state of the space devloped countries including the United Nations for the space exploitation of the medium and long term. It should be noted that this political drive will be necessary not only to set up the organization, but also during a subsequent period. It is desirable and necessary for us to establish the ISA in order to develop the space industry, to strengthen friendly relations and to promote research cooperation among the space-faring countries based on the new ideology and creative ideas. If the heads of the superpowers including the United Nations will be agreed to establish ISA at a summit conference, 1 am sure that it is possible to establish an ISA in the near future.

  • Last 50 years there were a lot of space subjects launched by space activities of many states and these activities also had created tremendous, significant space debris contaminating the environment of outer space. The large number of space debris which are surrounding the earth have the serious possibilities of destroying a satellite or causing huge threat to the space vehicles. For example, Chinese anti-satellite missile test was conducted by China on January 11, 2007. As a consequence a Chinese weather satellite was destroyed by a kinetic kill vehicle traveling with a speed of 8 km/s in the opposite direction. Anti-satellite missile tests like this,contribute to the formation of enormous orbital space debris which can remain in orbit for many years and could interfere with future space activity (Kessler Syndrome). The test is the largest recorded creation of space debris in history with at least 2,317 pieces of trackable size (golf ball size and larger) and an estimated 150,000 debris particles and more. Several nations responded negatively to the test and highlighted the serious consequences of engaging in the militarization of space. The timing and occasion aroused the suspicion of its demonstration of anti-satellite (ASAT) capabilities following the Chinese test of an ASAT system in 2007 destroying a satellite but creating significant space debris. Therefore this breakup seemed to serve as a momentum of the UN Space Debris Mitigation Guidelines and the background of the EU initiatives for the International Code of Conduct for Outer Space Activities. The UN Space Debris Mitigation Guidelines thus adopted contain many technical elements that all the States involved in the outer space activities are expected to observe to produce least space debris from the moment of design of their launchers and satellites until the end of satellite life. Although the norms are on the voluntary basis which is normal in the current international space law environment where any attempt to formulate binding international rules has to face opposition and sometimes unnecessary screening from many corners of numerous countries. Nevertheless, because of common concerns of space-faring countries, the Guidelines could be adopted smoothly and are believed faithfully followed by most countries. It is a rare success story of international cooperation in the area of outer space. The EU has proposed an International Code of Conduct for Outer Space Activities as a transparency and confidence-building measure. It is designed to enhance the safety, security and sustainability of activities in outer space. The purpose of the Code to reduce the space debris, to allow exchange of the information on the space activities, and to protect the space objects through safety and security. Of the space issues, the space debris reduction and the space traffic management require some urgent attention. But the current legal instruments of the outer space do not have any binding rules to be applied thereto despite the incresing activities on the outer space. We need to start somewhere sometime soon before it's too late with the chaotic situation. In this article, with a view point of this problem, focused on the the Chinese test of an ASAT system in 2007 destroying a satellite but creating significant space debris and tried to analyse the issues of space debris reduction.

  • The current international legal system does not provide a safeguard against the militarization and the weaponization of outer space. Although the term "peaceful use of outer space" in the 1967 Outer Space Treaty(OST) appears in official government statements or in multilateral space treaties, it is still without an authoritative definition in reviewing national practices. The ambiguous ban on weapons in Article IV of the OST allows countries to loophole on the deployment of other weapons other than nuclear weapons. Meanwhile "Draft Treaty on the Prevention of the Placement of Weapon in Outer Space and of the Threat or Use of Force against Outer Space Objects(PPWT)" to Conference on Disarmament (CD) commissioned by the UN General Assembly's Special Session jointly submitted by China and Russia in 2008 and later revised in 2014, attempting to define and prohibit the proliferation of weapons in outer space and provided definitions of prohibited weapons, are opposed by the US on the grounds that currently there is no arms race in outer space. Some experts support a hard law approach in which binding laws aimed at ultimately creating integrated and binding legal instruments in all aspects of the use of outer space should be adopted to regulate the military use of space. However as a temporary measure the soft law guidelines should be developed for the non liquiet, a situation where there is no applicable law. The soft law could be used to create support for the declaration of the treaties and to create international customary law. For example, the 1963 Declaration of Legal Principles Governing the Activities of States in the Exploration and Use of Outer Space that regulates the activities of the state in the exploration and use of the universe, and the 1992 Principles Relevant to the Use of Nuclear Power Sources in Outer Space will illustrated. While substantial portions of the former was codified later in the 1967 OST, the latter which, although written in somewhat mandatory terms, have been consistently complied with by states, have arguably become part of customary international law. On November 12, 1974, the General Assembly reaffirmed that the development of international law may be reflected inter alia, by declarations and resolutions of the General Assembly which may to that extent be taken into consideration by the International Court of Justice.
