NASA announced possible evidence of present-day liquid water on Mars. Scientists analyzed data from NASA's Mars Global ...

Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water -- enough to fill oceans on the planet's surface.

It is understood that oceans disappeared from the surface ... They say that the water frozen in Mars' polar ice caps can't account for it all - as well as when it happened, and whether life ...

Scientists know that millions of years ago, Mars was covered in oceans, but the planet lost its water over time and now has virtually no liquid water on its surface. Now, though, researchers have ...

Enough water to cover the surface of Mars in an ocean between one and two kilometers (0.62 and 1.24 miles) deep has been discovered within the crust of the Red Planet by NASA's InSight mission.

But that wet period ended more than 3 billion years ago, after Mars lost its atmosphere. Planetary scientists on Earth have sent many probes and landers to the planet to find out what happened to that ...

If Mars’ crust is similar across the planet, there may be more water within the mid-crust zone than the “volumes proposed to have filled hypothesized ancient Martian oceans,” the authors ...

CAPE CANAVERAL, Fla. — Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests. The findings released ...
