Details of research theme

【Title of Research Theme】
Scientific promotion of lunar and planetary seismology and strategic research for future interior structure exploration projects

 

【Details of research theme】
In recent years, seismological exploration of the interior structure of Mars has been actively pursued, including the success of the InSight mission to explore the interior structure of Mars, the decision to install seismographs in the polar regions of the Moon, and a full-scale plan to conduct seismic observations during the DragonFly landing mission on Titan, an icy celestial body. ISAS has begun to actively participate in the DragonFly mission by studying and developing seismographs to be provided to the mission.
Based on this background, this study aims to promote internal structure science using the seismological data acquired so far, and to establish a strategy targeting future projects.
Specifically, it consists of the following;
(1) Utilize and make full use of the lunar and planetary seismic data obtained to date (Apollo and Insight missions) to gain new knowledge of the interior structure.
(2) To advance feasibility studies on how to conduct observations to determine the interior structure of future unknown bodies seismologically based on data from the Earth, Moon, and Mars.
In addition to this, assuming we are currently selected as the in-house project to supply seismographs for DragonFly mission
3) To engage in the development of observational instruments (in this case, seismic measurement systems) that can be supplied to lunar and planetary exploration, and to engage in hardware development research (project contribution).
Through these invetigations, the program aims to develop "human resources who can lead future planetary exploration ".

Required abilities, qualities, and experience

Aerospace Project Research Associates are required to have the following three criteria
1) Have a track record of research using lunar and planetary seismic data, or be willing to do so.
2) Have a research plan to elucidate the seismic activity and internal structure of objects for which seismic data are not currently available, such as Titan.
3) Have a desire to develop lunar and planetary exploration instruments.

Ratios(Project Contribution)

Aerospace Project Research Associate will be assigned 50% for the DragonFly project. Of this engagement ratio, 25% will be for the appropriate estimation of expected seismic activity on Titan, operational planning, and study of the accuracy of the derived internal structure (2) above).
In addition, JAXA (ISAS) aims to be the technical lead for this seismograph, and he/she will be trained in hardware design and manufacturing in this environment (3 above).
The other 50% of the project is expected to contribute to the generation of scientific results using existing seismic data, related to (1) above.

Research environment after arriving at one’s post.

Aerospace Project Research Associate will be provided with relatively easy access to observational data acquired during the Apollo and InSight missions. Supercomputers will be made available for use as needed for research.
The planetary seismology research will be supported by the host institution's principal investigator (Satoshi Tanaka) and by collaborations with planetary seismologists outside the institute (both domestic and international). Assistant Professor Shiraishi and Mitani will support the development of seismographs and related hardware.
