The International Space Station (ISS) is being jointly developed by the following 16 international partners: The United States, Russia, Japan, Canada, Brazil, and the 11 member states of the European Space Agency. Assembly of ISS is a large-scale international program which commenced in November 1998, and is expected to conclude in 2006. Korea Aerospace Research Institute (KARI) is making effort to take part in the development of Payload Support & Interface Module (PSIM) for ISS. When success is achieved with ISS PSIM development project, Korea will have the rights to utilize external attached payload sites and research activities on ISS. Therefore preparation for the utilization of ISS EXPRESS pallet, JEM-EF, and Columbus-EPF need to be made. This paper shows the investigation results of the external attached payload sites for ISS and the application field of space and Earth science.

The International Space Station (ISS) orbits the Earth within the inner radiation belt, where high-energy protons are produced by collisions of cosmic rays to the upper atmosphere. About 6 astronauts stay in the ISS for a long period, and it should be important to monitor and assess the radiation environment in the ISS. The tissue equivalent proportional counter (TEPC) is an instrument to measure the impact of radiation on the human tissue. KASI is developing a TEPC as a candidate payload of the ISS. Before the detailed design of the TEPC, we performed simulations to test whether our conceptual design of the TEPC will work propertly in the ISS and to predict its performance. The simulations estimated that the TEPC will measure the dose equivalent of about 1:1 mSv during a day in the ISS, which is consistent with previous measurements.

The International Space Station (ISS) offers research opportunities to researchers through crew's space mission in the field of remote sensing. ISS provides the facilities to place and operate experiment equipments in a variety of fields, especially, microgravity experiments and Earth observations. This paper is intended to give readers a brief introduction to the ISS utilization and the capabilities for remote sensing researches. We investigate what kind of crew missions and payloads should be developed for remote sensing researches on the ISS.

Ministry of Science & Technology (MOST) and Korea Aerospace Research Institute (KARI) are preparing for the first Korean astronaut program based on the mid and long-term basic plan for space development of Korea from the year of 2003. KARI is making plans for the Korean astronaut's missions with Russia. To participate in the International Space Station (ISS) utilization through the Korean astronaut program, KARI investigates a lot of manned space missions. Among the suggested items, Earth observation on the Russian Module of ISS is the one expected mission for a Korean astronaut. This paper is intended to give readers a brief introduction of ISS Russian Module and research fields of Earth observation for astronaut's mission.

The International Space Station (ISS) offers research opportunities for researchers in the field of remote sensing to conduct world-class activities in Low Earth Orbit. ISS provides the facilities to place and operate research experiments in a variety of fields, providing investigators opportunities to perform research and Earth observation. This paper is intended to give the reader an introduction to the ISS utilization and the capabilities for remote sensing research that are being implemented through the development of research facilities. We hope that reader will consider what kind of payloads could be developed to take advantage of facilities, and will consider proposing remote sensing research on the ISS.

The purpose of this paper is to study about the legal system of the Inter-governmental Agreement on the International Space Station('IGA') which was signed on Jan 29,1998. This paper is divided into three main parts ; 1) a review of ISS, 2) the principal rules of IGA, 3) the legal system of IGA. First, the paper draws an outline of ISS by dealing with (1) the definition, characteristics, and functions of ISS, (2) the composition of ISS. Second, the paper explains the principal rules of IGA which include (1) the rule of 'Partnership' and (2) the rule of 'Peaceful Purpose'. Third, the legal system of IGA is studied by looking at five different aspects: (1) the registration system, (2) a general jurisdiction, criminal jurisdiction and a control of jurisdiction, (3) intellectual property rights and other rights beside intellectual property, (4) cross-waiver of liability and several elements in compensation of damages, (5) the dispute resolution. IGA contains new contents and applications of legal system which was not included in the former space law. Therefore IGA will work as a model law for international cooperation of space development. It is important for us to study the matter of ISS, because disputes on the ISS are left solely to contracting parties although IGA will regulate overall situations. The renewed IGA is even more important because all the space development is expected to take place on an international cooperation basis. On the basis of this paper, all the important parts of IGA is expected to be further studied so that the research can contribute to the establishment of the legal system of space development in Korea.

Due to a significant leap in the science and technology, the manned space exploration that has started with suborbital flights is now being expanded into the deep space. The space superpowers such as the U.S. and Russia have been making an effort to further develop the manned space technology. Among such technologies, the fire safety technology in microgravity has recolonized as one of the most critical factors that must be considered for the manned space mission design since the realistic fire broke out onboard the Mir station in 1997. In the present study, the flame characteristics such as flame ignition, shape, spread, and extinction that are critical to understand the fire behavior under microgravity conditions are described and discussed. The absence of buoyancy in microgravity dominates the mass transport driven by diffusiophoretic and thermophorectic fluxes (that are negligible in normal gravity) and influences the overall flame characteristics-flame ignition, shape, spread, and extinction. In addition, the cabin environments of the pressurized module (PM) including the oxygen concentration, ambient pressure, and ventilation flow(which are always coupled with microgravity condition during the ISS operation) are found to be the most important aspects in characterizing the fire behavior in microgravity.

The onset of fire on the International Space Station (ISS) is a critical problem that can threaten the life of crew members onboard and thus instantaneous fire detection and extinguishment technology has been considered as one of the most important aspects in the ISS operation. In the present study, a numerical analysis was performed to better understanding of the characteristics of smoke behaviors and detection in a pressurized module of the ISS using the NIST Fire Dynamic Simulator (FDS). Numerical results indicate that the smoke flow patterns under zero-gravity condition are clearly different from those under normal gravity condition. In addition, the results obtained from numerical simulations coupled with the PM internal flows are expected to provide basic and useful information in designing the microgravity fire detection devices and establishing in fire response protocol for astronauts or the crew members.
