Could Martian atmospheric samples teach us more about the Red Planet than surface samples?

NASA is actively working to return surface samples from Mars in the next few years, which they hope will help us better understand whether ancient life once existed on the Red Planet’s surface billions of years ago. But what about atmospheric samples? Could these provide scientists with better information pertaining to the history of Mars? This is what a recent study presented at the 55^th Lunar and Planetary Science Conference hopes to address as a team of international researchers investigated the significance of returning atmospheric samples from Mars and how these could teach us about the formation and evolution of the Red Planet.

Universe Today has surveyed the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, and comets, and what these fantastic scientific fields can teach researchers and space fans regarding the search for life beyond Earth. Here, we will discuss how planetary atmospheres play a key role in better understanding our solar system and beyond, including why researchers study planetary atmospheres, the benefits and challenges, what planetary atmospheres can teach us about finding life beyond Earth, and how upcoming students can pursue studying planetary atmospheres. So, why is it so important to study planetary atmospheres?
