There are major changes in the atmosphere of Mars

According to widely recognized knowledge. Mars' atmosphere is primarily composed of carbon dioxide (CO ₂ ), but also has small amounts of oxygen and methane that fluctuate over time. Since 1966, scientists have hypothesized that stable levels of CO ₂ in Red Planet's atmosphere could have a profound impact on the planet's properties.

Recently, another study related to the CO ₂ ice reserves in the southernmost part of Mars showed that it actually has a significant effect on the planet's atmospheric pressure. The reason is thought to be because Mars's atmosphere is very thin, with a surface pressure of 0.6% compared to Earth and the fact that Mars 'wobbles' on its axis to 10 degrees when orbiting the sun. , so the level of sunlight exposure on the planet's poles is not stable, leading to the fact that the amount of CO ₂ released from these poles is also less stable, causing un cycleed disturbances. in the atmosphere.

In other words, the giant CO ₂ ice sheets at the southern tip of Mars are sometimes exposed to direct sunlight, leading to sublimation (changing the state of a solid solid substance directly through the gas). , specifically here CO2 is transformed from solid to gas without going through the liquid phase. The huge amount of CO ₂ being pumped abruptly into the atmosphere will have a profound impact on the entire planet over the long term.

These changes are sufficient to reduce the pressure of the Martian atmosphere to a quarter or two times more than normal, despite the fact that the above process will take place very slowly, in a row. tens of thousands of years.

This shows strong evidence that the sublimation of CO ₂ ice is actually changing atmospheric pressure over time, thereby helping us understand how the Martian climate has changed in the past and will continue to change in the future - a very important factor to prove whether Mars exists or not.
