Mars Atmosphere

This website talks about how thin the atmosphere is on Mars. However, it says that even though it is thin, dust storms carried on the minimal wind still block much of our view of the surface of the planet often. This is not just due to the wind, but also to the decreased gravity of the planet. It looks at why Mars has a thin atmosphere. The people who wrote this article think that it was due to a large impact on the planet that occured some time ago in Mar's history. They believe that evidence of this impact can be seen on the face of the planet. They say that the impact is what altered the magnetic field, which was a major force helping the planet keep its atmosphere, and also that the impact itself tore away or burned away much of the atmosphere as well.
