   Mar 16, 2021 · The research challenges the current theory that the Red Planet's water escaped into space. The Caltech/JPL team 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 meters deep; a volume roughly equivalent to half of Earth's Atlantic Ocean.

   Mar 16, 2021 · The lighter-weight hydrogen escapes the planet’s gravity into space much easier than its denser counterpart. Because of this, the loss of a planet’s water via the upper atmosphere would leave a revealing sign on the ratio of deuterium to hydrogen in the planet’s atmosphere: There would be a very large amount of deuterium left behind.

   How much water does the Red Planet have?

   • New NASA-funded research shows a substantial quantity of its water – between 30 and 99% – is trapped within minerals in the planet’s crust, challenging the current theory that due to the Red Planet’s low gravity, its water escaped into space.

   Where did all the water go on Mars?

   • The question, then, is where did all that water go? The answer: nowhere. According to new research from Caltech and JPL, a significant portion of Mars's water -- between 30 and 99 percent -- is trapped within minerals in the planet's crust. The research challenges the current theory that the Red Planet's water escaped into space.

   What happened to the water on Mars?

   • Previously, scientists seeking to explain what happened to the flowing water on Mars had suggested that it escaped into space, victim of Mars's low gravity. Though some water did indeed leave Mars this way, it now appears that such an escape cannot account for most of the water loss.
