Astrobiology and Astrochemistry

The "Exobiology and Astrochemistry" theme focuses on selected solar system objects, in particular Mars, Titan and comets, as well as exoplanets, all of which are of great interest for exobiology and astrochemistry. The team's main scientific objectives are 1.) the search for molecular compounds in extraterrestrial objects, and 2.) the study of processes and reactivity leading to an understanding of the chemical composition of the objects studied. We develop laboratory experiments and numerical models simulating extraterrestrial environments, and participate in the design and production of chemical analysis instruments for space missions.
