Description of the thesis topic

The Bepi-Colombo mission is a collaborative mission between the European and Japanese space agencies. LATMOS laboratory is responsible for the operations and scientific analysis of the PHEBUS (Probing of Hermean Exosphere By Ultraviolet Spectroscopy) instrument which is a double channel spectrograph dedicated to the measurement of faint emissions from the exosphere in the ultraviolet range. This spectrograph can also characterize emissions from the surface near the terminator or on the nightside of Mercury.
Launched in October 2018, Bepi-Colombo will fly by Mercury 6 times before its insertion into Mercury orbit in December 2025. The first Mercury Fly-By will occur in october 2021.
The thesis subject consists initially in the preparation of the operations of PHEBUS including the choice of high interest targets for the various fly-bys. In a second part, the student will work on the scientific analysis of the first measurements to optimize the science operations and scientific return of the PHEBUS instrument during the nominal phase of the mission in orbit around Mercury.

Work Context

The Bepi-Colombo mission is the first European mission launched to study Mercury and its environment. This mission is a collaboration between the Japanese and European agencies. It is composed of two spacecraft that have been launched together in October 2018. They will separate just before Mercury orbit insertion in December 2025. The European Space agency is responsible for the Mercury Planetary Orbit that is hosting the PHEBUS instrument.

The successful candidate will interact with the LATMOS technical team to learn how to operate the instrument. In parallel, He/She will be in contact with the Bepi-Colombo operation team at ESOC/Darmstatd. Some activities klinked to data processing will be developped in collaboration with ESAC/Madrid. Some short-term work trips may be necessary in France or abroad.
