  • Human Space Activities / Utilization of the Space Environment

The International Space Station (ISS) project aims at improving science and technology to enhance life and industries on the ground. Fifteen countries are participating in the ISS project including the United States, Russia, European Countries, Canada, and Japan. Japan has completed its manned space facility "the Japanese Experiment Module Kibo," and trains astronauts who will operate the ISS and Kibo at JAXA.

About Human Space Activities

Space Environment Utilization and Space Experiment

By capitalizing on the space environment that is quite different from that of the Earth, JAXA conducts various research including R&D for new materials and for medical innovation.

International Space Station (ISS) and Japanese Experiment Module "Kibo"

At the International Space Station (ISS) flying 400 kilometers above the Earth, astronauts reside and perform various scientific experiments. The Japanese Experiment Module “Kibo” has a special feature of the Exposed Facility, where an experiment can be conducted outside the ISS (= an experiment instrument is exposed to the space environment), in addition to the inside facility. No other countries have such an outside facility.


A flexible attitude is imperative for experiments in the space environment to cope with changing conditions. An efficient and effective experiment process in cooperation with researchers on the ground is also very important. By sharing responsibilities between humans and devices based on their respective strong points, we can maximize our experiment results in space.
