Research for Secure Development and Success of Missions
Research on core technologies for spacecraft (mechanical systems engineering)

Among the technologies critical to spacecraft (satellites and other vehicles operated in space), our research focuses on core technologies required to operate spacecraft mechanical systems and components more reliably. We have been striving to overcome challenging new obstacles to meet the requirements for future space missions while ensuring the secure, reliable implementation of our ongoing projects.

To reduce the weight of spacecraft subsystems, prolong the operating lives of spacecraft, improve spacecraft performance, and develop a “satellite-friendly” mechanical environment, research has been conducted on improved chemical and electric propulsion, technologies to measure and control micro-deformation and micro-vibration, technologies capable of reducing the impact of severe mechanical environmental conditions on spacecraft, lubrication in extreme environments, cryogenics, etc.

We have also been researching a CO2 removal technology as a mainstay element of the life support systems during manned space flight, as well as a rover for robotic exploration. Both will be needed for future space missions.
