Operation-driven Robust Trajectory Design for DESTINY+ Mission

 

JAXA has been developing DESTINY+, a demonstration spacecraft for deep space exploration, which is scheduled to be launched in 2024. Although many researchers have studied advanced trajectory design techniques such as low-thrust spiral orbit raising, multiple lunar swingby, and three-body/four-body problem utilizing solar tidal force, few studies have been done to improve the robustness in such complex trajectories. This study promotes cutting-edge academic research on stochastic trajectory design, robust trajectory design, and autonomy, which will be used for the actual operation of DESTINY+.

Required abilities, qualities, and experience

(1) Expertise in mission design, trajectory design, orbit determination, and control.

(2) Communicate smoothly with domestic and international researchers, and promote joint research to develop new technologies
(3) Experience in the design/development/evaluation/operation/analysis of satellites and/or spacecraft is desirable.

Any restrictions/disadvantages for non-native Japanese speakers?

5 out of 9 researchers in the DESTINY+ flight dynamics team are non-native speakers of Japanese (as of September 2020), and they all communicate in English. Communication with the system manufacturer is limited because they speak in Japanese. The researcher can ask the supervisor/colleagues/secretary to help with Japanese communication.

Research environment after arriving at one’s post.

The research supervisor will take a leading role in guiding collaboration with researchers inside and outside of JAXA. A researcher holds a regular weekly meeting with the team and the other weekly meetings with the supervisor. A room, a workstation for orbital calculations (shared), and MATLAB software (licensed by JAXA) will be provided for research purposes.

 

Research leader

Specially-appointed Assistant Professor OZAKI Naoya

Location

Sagamihara Campus

Department

DESTINY+ Pre Project

Abilities, qualifications, and experience expected to be obtained at the end of the term

DESTINY+ aims to become a JAXA project at the beginning of FY2021 and to be ready for transport at the end of FY2023. Therefore, this position is an excellent opportunity to experience the whole process from the project's start to complete the development. In addition to the ability to carry out advanced research on trajectory design, researcher will be able to acquire a practical understanding of the SE&PM concept within JAXA by being actively involved in projects (focusing on operational planning).
