세계화 지구촌시대라는 이름이 무색하지 않게 세계로의 여행은 점점 자연스러워지고 있다. 미주, 유럽 등으로의 비즈니스 여행도 많아졌고, 휴가철이나 신혼여행, 수학여행 등 특별한 행사에 있어서 해외 관광지로의 여행도 이제는 흔한 일이 되었다.<중략>

We are now entering the era of Commercial Space Transportation with the rapid commercialization of space. Commercial Space Tourism will be realized first of all in the commercial space transportation and the spacecraft is developing for it led by private enterprise such as Virgin Galatic and XCOR Aerospace. The spacecraft for space tourism is developed as Reusable Launch Vehicle(RLV). RLV Spaceship I & II manufactured by the Scaled Composites for Virgin Galatic had completed experimental flight successfully and is going to put to the operation for space travel around the year 2012. In our country, Yecheon Astro-Space Center located in Yecheon, Kyungbuk Province, signed a binding-MOU with XCOR Aerospace and going to start space travel in the year 2013 with the spacecraft LYNX MARK-II. Thus, now space travel has become a reality to us. But it is also reality that there's no study by legal basis preparing for the space tourism domestically and internationally. In this regards, this thesis dealt with legal issues related to space tourism. These are as follows : (1) the applicabe law issue that is which law between air law and space law will apply, (2) the status of space tourist issue that is space tourist can be considered as personnel of a spacecraft and/or space flight participant and has the duty to obey the order of the captain of spacecraft, (3) the responsibility of the government for the non-governmental entities such as private enterprise which involved in space tourism in case space accident occurs during the space travel, (4) license permit and supervision issue by the government (In this point, for activating the market of the space tourism, I think it is essential to guarantee the safety of the spacecraft by the government authority, though U. S. government declared that it has not certified the launch vehicle as safe for carrying crew or space flight participants), (5) registration issue, (6) space insurance issue. For all the issues mentioned above, I have studied the existing international treaties and several country's domestic law to the space by referring U.S's Commercial Space Launch Amendment Act of 2004 and New IGA of 1998 and concluded that uniform legal regime to govern these issues should be established domestically and internationally in the near future.

전 세계적으로 우주로의 여행 (우주여행, Space Tourism)에 대한 많은 관심이 일어나고 있다. 특히 2004년 10월 4일 Scaled Composites사(社)의 SpaceShipOne이 2주 연속하여 지상 100km 정도의 지구 저궤도 (Sub-Orbital) 비행에 성공함으로써 이러한 관심은 폭발적으로 증가하고 있다. 이것은 우주여행이라는 것이 민간에 의한 우주 개발의 노력으로 시도된다는 측면에서 기존의 패러다임, 즉, 우주 개발은 국가 주도 하에서만 가능하다는 기존의 패러다임을 부정하는 상당히 획기적인 사건이기 때문이었다. 따라서 민간주도의 우주여행 사업에 대해 미국을 중심으로 한 민간업체의 개발 동향과 함께 지구 저궤도 우주비행체에 대한 (응용) 시장의 (창출) 가능성, 법적인 측면, 사업적 관점, 그리고 기술적 관점에서 바라보고자 한다.

Worldwide there is strong interest in the field of commercial space business, especially 100km altitude sub-orbital Space Tourism. This was soared to by the two-times flight success of SpaceShipOne by Scaled Composites Inc. It reached an altitude of 100km at Oct. 4, 2004. This demonstrates a paradigm change from government-driven space challenge and exploration to commercial space business. Therefore this report provides various insights into the commercial space tourism market, such as current demand for space travel, size of the market, growth potential of the market, technology, etc.

Radiation exposures of an astronaut during the space travels to the International Space Station(ISS) of the Soyuz and the Moon of the Apollo, were calculated considering the altitude, boarding time, period of stay, kinds of spaceships and space suits. The calculated radiation exposures decrease dramatically according to the thickness of the shielding by the wall of the spaceships and by the space suits. For the space travel to the ISS of Soyuz at Low Earth orbit, the thickness of the spaceship required to optimally reduce the radiation exposure is 3 cm. For the Extravehicle Mobility Unit(EMU) the exposures are minimized at 4 cm of the aluminized Mylar and 5 cm of the Demron, respectively. The aluminized Mylar showed better radiation shielding than the Demron which contains the high Z materials. The radiation exposures of an astronaut were $4.2\times10^{-6}$ Sv for the ISS travel and $4.3\times10^{-5}$ Sv for the Moon explore. The high concentration of the high energy proton flux at the surface of the Moon results in high radiation exposure. The calculation scheme and results of this study can be used in the design of the shielding performance of a spaceship and space suits.
