Mars had an Arctic-sized ocean, and scientists are only now beginning to see the outline of it. For a long time, the planet ...

Learn how researchers were able to use a climate model to uncover information about water on ancient Mars.

Mars has lost immense amounts of water over it lifetime, and scientists aren't sure exactly how. New research hints that the planet's violently varying tilt may be a key factor. When you purchase ...

Was Mars a friendly planet for water, even life, in its ancient past? Huge channel networks run across its surface. Rocks show signs of water immersion. Yet pictures sent back from NASA's Curiosity ...

Mars was once rich with flowing water. Today, it's a cold, dusty desert marked by dried riverbeds and empty lake basins. Traces of ancient streams wind across its surface, hinting at a time when water ...
