It has a tenuous atmosphere that evolved differently from that of Earth and Venus and a differentiated inner structure. Our knowledge of the structure and evolution of Mars has strongly improved thanks to a huge amount of data of various types (visible and infrared imagery, altimetry, radar, chemistry, etc) acquired by a dozen of missions over the last two decades. In situ data have provided ground truth for remote-sensing data and have opened a new era in the study of Mars geology. While large sections of Mars science have made progress and new topics have emerged, a major question in Mars exploration-the possibility of past or present life-is still unsolved. Without entering into the debate around the presence of life traces, our review develops various topics of Mars science to help the search of life on Mars, building on the most recent discoveries, going from the exosphere to the interior structure, from the magmatic evolution to the currently active processes, including the fate of volatiles and especially liquid water. specialized Mars Geological evolution Geophysics Atmosphere 060 064 24 art. 15 [107 p.] 2016 0935-4956 https://www.documentation.ird.fr/hor/fdi:010069316 10.1007/s00159-016-0099-5 0935-4956 [F B010069316] https://www.documentation.ird.fr/hor/fdi:010069316 https://www.documentation.ird.fr/intranet/publi/2017/04/010069316.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-05-09 2017-08-23 fdi:010069316 fre
