Aqueous alteration on Early Mars / Premiers environnements aqueux sur Mars

vendredi 6 mai 2016, par John Carter (IAS)

Mardi 24 mai 2016 à 14h00 , Lieu : Salle de confĂ©rence du bâtiment 17

I will present a review of new advances in our understansing of the states of liquid water during the early era (>3.5 Gya) of Mars, made possible in recent years thanks to numerous landed and orbital missions, and comparison with geochemical models and terrestrial analog sites. Mars remains slow to yield its secrets : the most essential questions regarding its past habitability and geological evolution are still open, and much debated. Several prospects to tackle these issues will be discussed.
