New Study Opposes Dry Mars Theory, Says 99% Water Still Trapped On Red Planet

TechShout - Mar 17, 2021 A significant portion of Mars’ water, between 30 and 99 per cent, is trapped within minerals in the planet’s crust, says a new study. The research, published in the journal Science, challenges the current theory that the Red Planet’s water escaped into space. The research team from California Institute of Technology (Caltech) and NASA’s Jet Propulsion Laboratory (JPL) found that around four billion years ago, Mars was home to enough water to have covered the whole planet in an ocean about 100 to 1,500 metres deep; a volume roughly equivalent to half of Earth’s Atlantic Ocean. But, by a billion years later, the planet was as dry as it is today.

Instead, their findings suggest the planet s water was lost through atmospheric escape as well as being locked up in the crust. On Earth, water that seeps into the crust forms mineral with water in their structure. The minerals are melted down and the water works its way back into the atmosphere through plate tectonics and volcanism. Trending Mars, however, does not have any plate tectonics so when the planet dried up, the drying was permanent.
