US EditionMartian volcanoes may have transported ice to the planet's equator
Simulations show volcanic eruptions billions of years ago transported water ice to Mars's equator, creating deposits that could support future crewed missions, researchers say.

When Fire Brought Ice to Mars
Mars is a planet of mystery! Its surface today is cold and dry, yet evidence suggests it was once home to flowing water. Most of the planet's remaining ice sits locked away at the poles, but recent observations have detected signals of hydrogen in equatorial regions that could indicate buried ice deposits where the environment should be too warm for ice to survive. How did frozen water end up at Mars's equator? It seems we might find the answer …
First fire, then ice: the Mars volcanoes once spewed not only lava and ash – they could also have left large ice deposits on the Red Planet, as a reconstruction shows. Because the eruptions hurled enormous amounts of water vapor into the Martian atmosphere, which then deposited as ice. This could explain where the ice deposits discovered at the Mars equator came from – and how they remained until today. Even on today's dry and cold Mars there is…
Explosive volcanic eruptions in early Mars may have transported water ice to the equatorial regions, according to a modelling study published in Natural Communications. The authors suggest that these eruptions could have created conditions that would allow these ice deposits to still exist today under the surface, which would expand our [...]
