This paper describes past experimental results, which would be excellent in each scientific disciplines such as crystal growth, fluid science and so on. The emphasized scientific target in the future which was established Space Utilization Science Committee is also noted. Meaning of Microgravity utilization is also emphasized that the concept of microgravity utilization should be modified. Ground base experiments are most important items compared to microgravity experiments. Microgravity experiments should be done to make clear the unknown scientific area, which would be picked up under ground base experiments. International collaboration is also emphasized to get several kinds of flight opportunities such as sounding rocket, recovery satellite and so on. Microgravity experiments should be done by most suitable method with the scientific purpose as well as experimental technology. For instance, ISS with crews is not suitable opportunity for combustion experiments, because many safety issues prevent most favorite experiments parameter. The systematic experimental results should be target for the time being, because previous experimental results were scattered as point and line in unknown scientific area. Therefore, we need to forces on to get systematic scientific result from microgravity experiments, which contribute to improve the science including ground base.
The projects of biological and physical sciences in space are promoted by ISS Science Project Office, ISAS/JAXA. The status and future plan of the projects are introduced and prospects of the science field are discussed together with the governmental activities for strategic evaluations and coordinations by the Headquarters of Aerospace Strategy and the Aerospace Strategy Technical Investigation Panel under the Cabinet Secretariat.
Since the operation period of the International Space Station (ISS) will be expanded to 2020, the revision of the ISS utilization scenario is being discussed. This paper firstly summarizes the differences between Space Shuttle utilization and the ISS utilization. Then, a practical strategy how the research objectives should be set, how the concept of experiment hardware design should be, how obtained data should be treated, and how the research team should be are discussed. Finally, current strategy for the utilization of the electrostatic levitation furnace is presented.
In this July, Space Shuttle Atlantis had safely returned to Kennedy Space Center. This was a last mission of all space shuttle programs lasted for 30 years. After the Space Shuttle retirement, space life science experiments will suffer from significant limitations, especially sample transport and recovery. Space life science experiments from 2011, must be more highly feasible operation and experiment plans. Meanwhile, the International Space Station (ISS) will be extended until 2020, it would be compulsory to have increasingly strong demand for a cost-effective research results. In addition, after the devastating earthquake disaster on this March 11 in east side of Japan, the budget of the space development and others except earthquake reconstruction will be very tight. Under such circumstances, space life science researchers themselves not only rely on JAXA should be necessary to consider the future research strategy including the need, the importance, for further development of space life sciences. Here is a personal opinion about the direction of future research as one of space life science researcher not only as a JAXA scientist.
The Multi-purpose Small Payload Rack (MSPR) with the Chamber for Combustion Experiment (CCE) was successfully launched toward the ISS/JEM(Kibo) by HTV-2/H-IIB-2 on January, 2011. This means that new era will start for microgravity combustion research. 4 combustion related researches have been already selected as candidates for experiments on the Kibo. At present, preparation for these experiments including detail consideration of experimental plan as well as development of experiment unique hardware is on-going. Excellent scienitific output toward future innovation of combustion technology is expected from these investigations, since development of advanced combustion technology is essential for solution of energy and environmental issues. In the present report, information on facilities for combustion research on the ISS as well as on 4 planned investigations on the Kibo will be introduced. Finally, expected evolution of microgravity combustion research in next decade will be described.
Chemical processes are basically molecular ones and are generally not affected by the gravity. But it is reasonable that the gravity affects the processes of larger size even in the chemical systems. The meso-scopic chemical systems are the examples of above. In this research work, we have studied the following subjects as the meso-scopic chemical systems: i) Dissipative structure formation under variable gravity, ii) Chemical processes in the critical density fluctuations, iii) Effects of gravity on colloidal assemblies, iv) Liquid droplet motion by photocheminal Marangoni effect, v) Spontaneous rotation of the nonlinear charged colloid patterns under gravity, and vi) Preparation of honeycomb capsules. In this report the first research subject is mainly discussed, since this is most developed one. The experimental results have already been obtained under the hypergravity and by the parabolic flight.
Although the Japanese apparatuses for fundamental physics have not been onboard the International Space Station, experimental data in this research field have been obtained through international collaboration and parabolic flights. The Japanese microgravity experiments in this field at present are complex plasmas and helium crystal growth. In this paper, current status of complex plasmas research is described since this is an experiment project of the ISS Science Project Office at Japan Aerospace Exploration Agency. After that, some future visions of this field are described and discussed by considering the possible strategy until 2020.
The current situation of the crystal growth experiments conducted in Kibo and the future direction of crystal growth researches are mentioned from a perspective of scientific utilization. The following subjects are proposed as the future researches using Kibo: (1) understanding of crystal growth mechanism, (2) validation of influence of unmeasurable effect under a terrestrial condition upon crystal growth, (3) growth of high-quality crystal, and (4) reproduction of crystallization in space.
IHI AEROSPACE Co.,Ltd. (IA) had developed and have been developing an important part of the International space station JEM “Kibo” and the many kinds of the experiment equipments in space from the start point of the Japanese space development. Now, the Exposed Facility (EF) and Pressurized Module (PM) of “Kibo” have been utilized for the technical test bed on orbit and the laboratory on orbit, for example, life science, medical science and material science experiments in microgravity in “Kibo”. And IA hopes to continue space utilization on earth orbit and start space utilization on Moon. IA will be developing the important system and experiment equipments for space utilization in future.
