NASA | MAVEN Science Teaser

The video discusses the history of Mars' atmosphere, focusing on its transition from a thicker, warmer state to the current cold, dry environment. It introduces the Maven mission, which aims to understand the reasons behind this climate change by studying the upper atmosphere and how gases are lost to space. The video also covers the processes controlling the atmosphere and provides insights into the historical changes Mars has undergone.
