Research for Secure Development and Success of Missions Advancement of basic technologies on mechanisms and materials for expanding space activities

To enable more flexible, extensive, and long-term space activities, we aim to establish technologies for accurately measuring and predicting the space environment, as well as basic technologies on materials, mechanisms, and structures that can apply to severe environments and commonly used equipment, such as batteries and attitude control actuators.

The Value of Our Research

New utilization is being considered for future satellites, such as optical observation in ultra-low Earth orbit and geostationary orbit, and secondary utilization taking advantage of long satellite life. In addition, space activity is expanding from Earth's orbit to the Moon.

To conceive and develop novel and flexible space missions, it is important to predict the environment of the activity area accurately. In addition, it is necessary to achieve a high level of tolerance to the environment and a wide range of operational conditions for the essential basic technologies and commonly used equipment.

Research Goals

This research addresses ten sub-themes for six main environments under the following two goals.

For the satellite orbital environment, to develop technologies that relax the restrictions of system operation by more than doubling the operational range or technologies that contribute to the realization of new orbital use and secondary use of satellites.
For the lunar surface environment, develop technologies that expand the range of activities by a factor of ten or more and those that significantly increase the duration of activities.

Sub themes

Vacuum and Planetary Atmospheres


Radiation and magnetic fields
