| Outline of Annual Research Achievements |
The research focuses on the design of low-thrust trajectories in multi-body systems. The goal is to develop robust tools and methods which can be applied to a wide range of missions, such as a deep space mission with encounters at multiple celestial bodies, Earth-Moon libration point missions. The research can improve the current design process and help finding better results for future space missions, thus saving total mission cost and extending the potential capability of a mission.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The following achievements have been made during the 2015-2016 period.
1) Implemented and tested a high fidelity low-thrust trajectory design tool GALLOP. Results presented at the International Symposium on Space Technology and Science in Kobe.
2) Applied the tool to design future space missions: DESTINY+ visiting the asteroid 3200 Phaethon, and the Maritain sample return mission MMX. Results presented at the AAS/AIAA Space Flight Mechanics Meeting, Napa, USA.
3) Extended the research work to study the two-point boundary-value problem of low-thrust trajectories, which can serve as a basis to help improving the current optimization methods. Results presented at the AAS/AIAA Space Flight Mechanics Meeting, Napa, USA.
4) Collaborated with the European Space Agency to participate in the 8th Global Trajectory Optimisation Competition and won the champion of the contest among 30 teams in the world.

| Strategy for Future Research Activity |
The high fidelity, multi-body orbital design tool will be applied to design the Earth-Moon transfer of the small satellite mission EQUULEUS and the lunar lander OMOTENASHI, which will be launched in 2018 with the NASA Space Launch System rocket. Preliminary analysis will be done by the summer of 2016. Research results will be presented in an international conference and published as a peer-reviewed journal article.
