Science for just $15 USD. Burying Mars' ancient water in the crust Mars once had oceans of liquid water on its surface but little of that water remains today in the planet's ice caps and atmosphere. This discrepancy is usually interpreted as loss of water to space, supported by the atmospheric deuterium/hydrogen (D/H) ratio, but this has been difficult to reconcile with other constraints. Scheller et al. propose that water could instead have been incorporated into minerals in the planet's crust, which were later buried (see the Perspective by Kurokawa). They simulated the evolution of the D/...

Geological evidence shows that ancient Mars had large volumes of liquid water. Models of past hydrogen escape to space, calibrated with observations of the current escape rate, cannot explain the present-day D/H isotope ratio. We simulate volcanic degassing, atmospheric escape, and crustal hydration on Mars, incorporating observational constraints from spacecraft, rovers and meteorites. We find ancient water volumes equivalent to a 100- to 1500-meter global layer are simultaneously compatible with the geological evidence, loss rate estimates, and D/H measurements. In our model, the volume of w...
