Mars’ Atmosphere Changes with Tilt of Axis
New evidence confirmed by NASA, shows that the atmosphere on Mars is constantly changing and it fluctuates dramatically as a direct result of the tilt of its axis. This change in atmosphere directly affects things like dust storms. Such drastic changes in the atmosphere can also affect one substance that NASA is still in search of on the red planet, water. If water can be found on Mars, then we know that there is a higher probability that life could exist too, but these massive shifts in atmosphere can boil away any water that may or may not exist.
Scientists believe that the change in atmosphere is caused by the amount of carbon dioxide that is currently present in gas form. Large pockets of frozen carbon dioxide or dry ice have recently been discovered beneath the planet’s surface. For comparison, the latest pocket of dry ice is similar in size to Lake Superior, which is almost 3000 cubic miles.
As Mars rotates around the sun, it tilts and changes its axis much like our planet. Scientists think this might cause some of the frozen carbon dioxide to be released into the air, making the atmospheric changes that have been observed. This change could also increase the actual tilt effect.
When the majority of the carbon dioxide found on Mars is in the atmosphere, it creates a greenhouse effect much like our planet. The atmosphere gets thicker and as a result the planet surface could become warmer. There are huge polar ice caps that have the opposite effect. They are trying to keep the surface of Mars cool.
