Workshop objective

The last 10 years, the space exploration of Mars and small bodies of the solar system significantly increased. The interest toward Mars recently rose due to the discovery of regions where liquid water has flown in the past history of the red planet. Small bodies, and particularly asteroids, are studied to have a better understanding of the formation and evolution of the solar system.

The NASA Mars Science Laboratory mission is dedicated to assess the habitability of the Gale crater region. With this aim, the rover Curiosity onboards 10 instruments which collect since the 6th august 2012 information related to mineralogy, chemical composition, environmental conditions (radiations, pressure, temperature...)… All the results obtained up to now allowed to characterize physic-chemical properties of the lower region of the crater where liquid water is supposed to have been present for a long period of time. The French community strongly contribute to this exploration through its participation to the Chemcam (rocks elemental composition) and Sample Analysis at Mars (soil and atmospheric molecular composition) instruments.

The NASA Dawn space probe stayed in orbit around the Vesta asteroid from august 2011 to august 2012, to collect images and spectra (visible, infrared and gamma) of its surface. These data reveal a body with a complex geology, contrasted hemispheres, regions enriched in hydrated minerals and a composition confirming its relation with HED (Howardite – Eucrite – Diogenite) meteorites.

This workshop will give the opportunity to present more details scientific results of these two space missions..
