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.

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 ...

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 ...

A new study suggests Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to ...

Running those numbers, Clarke and his co-authors estimate that of the mile-deep layer of water that may once have been the ...

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 ...

So - how did a mission that went to Mars to analyse marsquakes and seismic activity discover what may be an ocean's worth of water over 10 kilometres below the surface? The C-S-I-R-O's Glen Nagle ...

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 that Mars may be drenched beneath its surface with enough water, trapped in tiny cracks and pores of rock, to form a global ocean. According to the findings released Monday ...
