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.
