Researchers have found new evidence for a massive subsurface ocean on Mars, again raising the possibility of microbial life.

Robert Zubrin, the planet’s leading strategist for landing humans on Mars, predicts SpaceX’s Starship will win the race to ...

Mars might hold enough subsurface water to cover its surface in a global ocean between 0.62 to 1.24 miles (1 to 2 kilometers) ...

Once Mars dried out, this rusty rock was broken down into dust over billions of years. Strong winds blew this dust all over the planet’s surface, gradually turning Mars red. Signatures of the ...

and so must have formed when Mars still had water on its surface. The ferrihydrite has kept its watery signature to the present day, despite being ground down and spread around the planet since ...

Over billions of years, this rusty material has been broken down into dust and spread all ... Because of the absence of liquid water on Mars’ surface today, those rusty red minerals were thought ...

If you've ever looked at Mars through a telescope ... Those sheets "weighed down" the surface, compressing it. As the glaciers melted, the surface began to rise back up in a process called ...

The model estimated Mars's subsurface water distribution down to 2 meters from the surface. Like a sponge, highly absorptive regolith in Mars's mid- and low latitudes retains substantial amounts ...

S-waves which oscillate up and down, perpendicular to the direction of travel; and surface waves, which travel along the surface of Mars similar to ripples in a pond. The new research was focused ...
