SO Webloquio: Asteroid sample return: A laboratory perspective

The new generation of sample return missions from small bodies is delivering to us fresh witnesses from the early Solar System. In this context, laboratory studies play a double role: on one hand, in-depth laboratory analysis of retrieved samples using state-of-the-art techniques give us an unprecedentedly detailed look at the formation and evolution of organic materials in asteroids; on the other hand, in the laboratory we can perform experiments to reproduce astrophysical processes occurring in space and to support the interpretation of the remote sensing observations. The results of the analysis on retrieved samples may stimulate new laboratory experiments, in order to deepen the understanding of what has been observed at the microscopic scale, and support further the interpretation of remote observations. In this presentation I will show some recent laboratory results obtained on extraterrestrial materials at IAS-Orsay and at the SMIS IR beamline of the SOLEIL synchrotron (France), in support of the observations of asteroid Ryugu by the Hayabusa2 mission (JAXA) and in preparation for the laboratory analysis of samples retrieved from Ryugu.
