ABOUT
Playing in Space, Fascinating System Development
In this laboratory, we conduct practical research to create, develop, and demonstrate our ideas in space, based on the principle of contributing to society by realizing new ideas using space as a place of activity. In order to achieve this goal successfully, we need to have a strong foundation in our field, flexible and calm judgment, and a passionate heart that will not give up.

The current main target is nano-satellite systems. In particular, we are focusing on system reconfiguration and variable shape functions, and our main research target is evolved, deformable, and reconfigurable space systems. In the future, not only single spacecrafts but also formation flight missions with many spacecrafts and large scale space platforms for assembly and reconfiguration will be required in Earth orbit, Moon, Lagrange point, planetary orbit, etc. I imagine that systems of dozens, hundreds, and thousands of spacecraft will be required to be combined, reconfigured according to the situation, and operated specifically for the purpose.
