poles in the process. Massive impacts could have delivered additional water of their own, and early Mars might have held enough surface water to cover the surface of the planet to a depth of 1,500 meters. These uncertainties are why the Global Equivalent Layer (GEL) estimates are so ...
Mars is covered in evidence of ancient lakes, rain and snow — but scientists aren't sure how that's possible 'Marsquakes' reveal clues about a hidden body of water on Mars Geysers on Saturn's moon Enceladus may not come from its underground ocean What happened to all the water on...

Frost forms on the rocks at night, but as dawn approaches and the air gets warmer, the frost turns to vapor, and there is 100 percent humidity until it evaporates. The high humidity could help make Mars more habitable, if the water condenses to form short-term puddles in the early morni...
