The Martian Atmosphere

Mars' atmosphere is very thin, composed mostly of carbon dioxide (about 95%), with small amounts of nitrogen, argon, and traces of other gases. It has less pressure than Earth's, equivalent to less than 1% of Earth's atmospheric pressure at sea level, making it unable to support human life without assistance. The thin atmosphere leads to extreme temperature fluctuations and little protection from solar radiation. Despite its fragility, understanding Mars’ atmosphere is crucial for future exploration, as it influences landing, habitats, and potential terraforming efforts.
