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

Mars has an atmosphere that's about 95% carbon dioxide.
The atmosphere on Mars is thin because it is 95.72% carbon dioxide.
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.

Mars' moons have no atmosphere
Distribution of methane is in the atmosphere of mars.
The atmosphere on Mars is mostly carbon dioxide.
Mars has a very thin atmosphere. Based on astronomical measurements and information from Mars probes sent by NASA, carbon dioxide dominates the atmosphere of Mars.

what is an atmosphere for mars
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.
Venus has a low atmosphere and it is rally hot
