Details of research theme

【Title of Research Theme】

Research on ultra-small spacecraft system with high ΔV capability for frequent deep space access

 

JAXA/ISAS aims to deploy ultra-small spacecraft weighing from a few kilograms to 100 kilograms for deep space exploration missions, in addition to the conventional explorers weighing more than several hundred kilograms, in order to realize challenging deep-space exploration missions at a high frequency. In particular, in order to achieve frequent access to deep space regions that are relatively close to the Earth (e.g., near-Earth asteroids and Mars), the most promising method is to utilize launch opportunities to GTO or lunar transfer orbit and escape to deep space by using the high ΔV propulsion system (kick motor) of the spacecraft itself. In order to realize such a world, it is necessary to integrate various research and development activities into a spacecraft system, such as complex orbit design and mission design using swing-by, spacecraft GNC (guidance, navigation and control) associated with kick motor operation, and measures to ensure reliability to operate the spacecraft for long-term deep space missions.
ISAS has been conducting research and development for the realization of a relevant technology demonstration mission, which is expected to include a specific science mission. In this theme, the applicants are expected to promote your own research in relation to the advanced technical challenge(s) specific to this mission as mentioned above, and also contribute to the promotion of the project by integrating your research results into the spacecraft system, thus contributing to the promotion of this R&D project as a whole. Through the experience of implementing such an advanced and challenging mission on a small scale, we expect the applicants to gain the ability and experience to lead a larger mission in the future, both in terms of research and project management.

Required abilities，qualities， and experience

(1) Applicants should have expertise in one or more of the subsystem/system technologies that make up a nano or micro-satellite or spacecraft.
(2) Applicants should be able to communicate smoothly with domestic and foreign researchers and engineers to promote joint research.
(3) It is desirable for applicants to have experience in the design, development, evaluation, operation, and analysis of components (including satellite systems and onboard equipment), regardless of the research field.

Research environment after arriving at one’s post.

Most of the facilities necessary for the development of spacecraft system are maintained by JAXA or its collaborating research institutes and can be used for the research. Consult with us if you need equipment that is specific to your field of expertise and not owned by JAXA or cooperating organizations.
The host supervisor/research advisor will be responsible for providing guidance, and the research will be conducted in close collaboration with related departments in JAXA specializing in ultra-small spacecraft technology, as well as with collaborating researchers in Japan and overseas.
