By discovering carbonate rocks, NASA's Mars rovers may have unlocked the key to understanding the fate of the Red Planet's ...

How cold winters are on Mars depends on the tilt of its axis. The more tilted towards the sun the northern hemisphere of the ...

The simulations suggest that if ice was present at these gully locations when Mars’ axis tilted to about 35 degrees, the conditions would have been just right for the ice to melt.

One day, Mars will tilt to 35 degrees again, ... As Mars tilts on its axis to 35 degrees, the atmosphere becomes dense enough for brief episodes of melting to occur at gully locations.

The south pole of Mars has a layer of dry ice that is 30 times thicker than previously thought, a find that suggests the Red Planet may have had more liquid water on its the surface in the distant ...

They say that if ice was present at gully locations in the areas they looked at when Mars' axis tilted to about 35 degrees, the conditions would have been right for the ice to melt because ...

During periods when Mars’ axis tilt (or obliquity) was higher, the planet experienced more intense warming at the poles. This caused more water ice to sublimate (turn directly from ice to vapor ...

How cold winters are on Mars depends on the tilt of its axis. The more tilted towards the sun the northern hemisphere of the Red Planet is, the warmer it gets and vice versa.

In a 2015 study, for instance, the researchers showed it was possible that there may have been past periods on Mars when water was available to form gullies if Mars tilted on its axis enough.
