Planetary Instruments based on Optical technologies for an iNnovative European Exploration Using Rotational Seismology

Periodic Reporting for period 1 - PIONEERS (Planetary Instruments based on Optical technologies for an iNnovative European Exploration Using Rotational Seismology)

Reporting period: 2019-01-01 to 2019-12-31

Internal structure of planetary bodies are poorly known. We want to image their interiors in order to understand the formation of solar systems and how planets become habitable, and to help protecting Earth from asteroid threat.
In order to perform this imaging, we develop two innovative 6 degrees of freedom (6 DoF, with 3 translations and 3 rotations) instruments, based on optical interferometry, for measuring ground deformation of planetary objects. The first instrument is a prototype of very low noise 6 DoF sensor dedicated to internal structure imaging of terrestrial planets. The second one is a space qualified compact version of the same instrument concept for exploration of small bodies.
Instruments are currently designed based on scientific requirements produced during the first year of this project through simulations, and data analysis of existing planetary seismology data sets, including recent Mars seismometer deployed by INSIGHT mission.
The first prototypes of high performance and compact instruments sensing elements have been produced. Mechanical, thermal and system instrument studies have been performed. Final instrument requirement review and preliminary design reviews of sensors will be performed in Januray 2020.
A terrestrial analog experiment was performed with various 6 DoF sensors. A research of high performance (in term of vibration noise) test facilities is on-going.
6 international conference presentations of the project have been performed, and web site and project identity have been set.
An improvement of instrument noise of two orders of magnitude is expected for the planetary prototype by using optical sensing technologies. At the end of the project, the flight model of compact instrument will be able to target a space mission in direction of an asteroid body.
Both instruments will open new markets for terrestrial, space and planetary applications.
Beyond the science aspects related to the understanding of planetary systems and their evolution (or not) into habitable environment, the asteroid internal structure imaging is participating to the planetary defense effort.
The project also fund, train and benefit from young research and engineer professionals, involved in high quality research and industrial teams across europe.An improvement of instrument noise of two orders of magnitude is expected for the planetary prototype by using optical sensing technologies.
