Mars and Earth share similar origins: rocky planets with water and carbon, located in a potentially habitable zone. Yet one ...

For decades, scientists have theorized about how Mars reached its current state. Many believe that the Red Planet's surface ...

Researchers examining Noachis Terra in Mars’ southern highlands found evidence of extensive river networks – some hundreds of ...

By studying seismic waves, researchers have found a layer deep beneath the surface of Mars that could contain enough liquid water to flood the planet with an ocean thousands of feet deep.

After its voyage past Mars, Mariner 4 maintained intermittent communication with JPL and returned data about the ...

A new study posits that dark streaks originally believed to be signs of water on Mars' surface might not be that at all.

NASA's Curiosity rover has snapped its first images of web-like "boxwork" features on the surface of Mars. The zig-zagging rocks could provide clues about the Red Planet's watery past and whether it ...

Scientists have found seismic clues that suggest liquid water may be hiding beneath Mars' surface. By listening to the echoes of "marsquakes" — seismic waves rippling through Mars' crust ...

Satellite images suggest long, dark streaks on Mars may not actually be related to water on the Red Planet.

Liquid water once shaped the Martian landscape dramatically, carving valleys, filling lakes, and forming vast oceans. Billions of years ago, during Mars' early days known as the Noachian and ...

Researchers analyzed a global database of 500,000 strange streaks that occur on steep Martian slopes, concluding that they're most likely caused by dry processes rather than liquid flow.
