Research for Secure Development and Success of Missions Strategy Building and Capability Enhancement on In-Space Propulsion

The propulsion systems used in satellites and probes are called "in-space propulsion.” There are two types of propulsion systems: electric propulsion, which has lower thrust and lower fuel consumption, and chemical propulsion, which can generate higher thrust.

The primary objectives of this research are to build a strategy for effective R&D of in-space propulsion and to strengthen its basic capabilities. We are currently conducting three main researches: electric propulsion (Hall thrusters), chemical propulsion (using green propellant and for landing on celestial bodies), and multimode propulsion.

The Value of Our Research

In-space propulsion systems are indispensable for "moving" in space, and they are applied to a wide variety of applications, including satellites in low Earth orbit, geostationary satellites, and probes and vehicles aiming for the Moon, Mars, and beyond. Therefore, it is important to build a strategy on how to research, develop, and commercialize the appropriate propulsion systems for various applications, and to enhance the technological capabilities for realizing the strategies.

Research goals

Strategy Building

This activity will provide direction for research, development, and utilization of in-space propulsion by overviewing the wide variety of propulsion technologies and their applications.

Capability Enhancement

This activity will appropriately enhance the essential technologies on in-space propulsion such as Hall thrusters and some chemical thrusters required to independently carry out various space missions.
