NASA said today that new data from the Mars Reconnaissance Orbiter (MRO) has demonstrated that the amount of atmosphere on the Red Planet depends entirely on the tilt of its axis. This is ...

As the sun grew hotter, so did Mars, prompting much of its atmospheric carbon dioxide to rain out and ultimately get locked ...

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

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 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.

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 ...

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 ...

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.
