Foreword In the long-term policy forum of the NASDA, from the long-term point of view toward the 21st century, we put forward the opinions of all parties and put forward the research direction of Japan’s space technology. Accordingly, research and development of space stations and others began to be used as a permanent base for space activities. Then from the late 1990s to the beginning of the 21st century, the use of space stations and the various platforms around it as well as the study of space shuttle will be carried out.
