Assistant Professor CHUJO Toshihiro recieved the 23rd Tokyo Tech Challenging Research Award and the Suematsu Challenging Research Award.
The Award Ceremony will be held on September 13th, 2024.
To encourage young faculty members at Tokyo Tech to engage in challenging research, Tokyo Tech has established the Challenging Research Award for creative, up-and-coming researchers who boldly pursue the promotion of the most advanced research in the world, pioneering of new fields of study, innovative development of new research, and important issues that are difficult to solve. We commend the recipients of this award and provide them with financial support for their research.
Many of the researchers who won this award have also gone on to win the Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology.
In 2024, 11 researchers, including Assistant Professor CHUJO, were selected, and of whom Assistant Professor CHUJO and two others won the Suematsu Challenging Research Award※.

Integrated Attitude-Orbit Control and Mission Design of Solar Sail and Preparation for Technology Demonstration in Space
I am very honored to receive the prestigious Tokyo Tech Challenging Research Award and the Suematsu Challenging Research Award. I would like to express my sincere gratitude to my co-researchers, students and staffs in our laboratory and research group, and my family who supported my research.
Solar sails are a propellant-free propulsion system that uses solar radiation pressure. It is particularly compatible with lightweight micro spacecraft, and I believe it is one of the important technologies that will be useful for frequent space exploration missions by micro spacecraft. In order to use a solar sail, mission design (orbit/trajectory design) based on an understanding of orbital mechanics and control to follow the designed orbit/trajectory are required. However, since the orbital control of a solar sail is performed via attitude control, a concept of integrated attitude-orbit control is necessary. In this research, we established the integrated attitude-orbit control law using a gimbal mechanism equipped on the sail deployment part, and designed various orbits and trajectories assuming missions near the moon and Lagrangian points. We are also preparing for a technology demonstration mission in space, aiming to apply it to deep space exploration in the future.
