Solar and Planetary Systems

The activities of the team are focused on three major investigations: study of the processes of evolution of the planetary bodies of the Solar System, study of exoplanets, and study of the initial conditions of the Solar System. More specifically, we attempt to study:

- evolution processes by observations of differentiated bodies (terrestrial and giant planets, satellites). These activities are performed through space instruments mounted on orbital or in situ platforms;
- the extra-solar planets by a theoretical but also observational approach through the COROT, PLATO and ARIEL missions;
- the initial conditions for the formation of the Solar System through the study of primitive matter: cometary grains, meteorites, observations of primitive bodies and the interplanetary environment.

Our approach consists in coupling the observation acquired by space instruments, extensive data reduction, numerical modeling and laboratory measurements. These multiple approaches are based on as strong and major instrumental developments with the constant concern to combine both scientific and technological challenges.

Meeting in Paris on 18-19 June, ESA's Science Programme Committee (SPC) gave the go-ahead to continue funding science operations for 10 remarkably productive science missions (including SOHO and Mars Express), all of them working beyond their planned lifetimes and all of them nevertheless continuing to deliver exceptional science.

ESA celebrated the 10 year anniversary in space of Mars Express, launched on June 2, 2003 from the Baikonour space centre. Mars Express, which is still in operation, is the first planetary space mission of ESA. For the first time, the satellite performed coupled analyses of the various Martian envelopes, from the exosphere and the high atmosphere to surface and subsurface, thanks to six instruments, including OMEGA, of which IAS is Principal Investigator. This space mission was very successful; it changed major paradigms in understanding the history of Mars.
