New research explains why water ice on Mars hides under a layer of dust and estimates its age — no older than 4 million years.

On Mars, beneath a thin layer of dust, hides water ice — left over from a time when the planet was more tilted. The ice evaporated, and the dust wrapped it up like a blanket. Now scientists have figured out this ice is no older than 4 million years. For future expeditions, this means: water is really close, you can drill for it.

🎯 On Mars, ice behaves like dry ice on a theater stage: it slowly evaporates, skipping the liquid phase, leaving only a dusty trail.

🎬 In the movie 'The Martian,' the hero extracts water from the soil — exactly as can be done with subsurface ice on Mars.
