How and why did mars lose its atmosphere?

Mars had a molten core that eventually cooled. Causing it to loose its magnetic field allowing solar winds and radiation to "wipe out" its atmosphere.


How did Mars lose its atmosphere?

The planet Mars is slightly smaller than the Earth and therefore has a weaker gravitational field. Gravity is what holds an atmosphere in place. In a weak gravitational field, an atmosphere will gradually leak away into outer space. That's what happened on Mars.


Did mars lose its atmosphere because of intense solar winds?

Yes. The current theory is that once Mars' core solidified, its magnetic field disappeared, allowing solar wind to gradually dissipate the atmosphere into space.

What caused Mars' atmosphere to decinagrate and lose all its liquid water?

As Mars has cooled, its core has solidified and its geodynamo stopped. The loss of Mars' magnetic field allowed more solar energy to reach the surface. That solar radiation heat dissipated the surface water and atmosphere. Also, because Mars' gravitational field is not as strong as earth's, it was much easier for atoms and molecules at the top of the atmosphere to escape to space. Over millions of years this process led to the loss of most of Mars' atmosphere.
