How solar winds stripped the Martian atmosphere and changed its climate forever
In short: This video explores how NASA's MAVEN mission quantified the rate at which Mars loses gas to space. By analyzing argon isotopes, scientists have uncovered the mechanism behind the planet's transition from a warm, wet world to a cold, arid desert.
The Mars Atmosphere and Volatile Evolution (MAVEN) mission has determined the current rate of atmospheric loss caused by solar wind stripping. By measuring both light and heavy isotopes of argon, researchers discovered that the majority of the Martian atmosphere was lost to space. This continuous loss of gas is believed to be a primary driver in the planet's evolution from an early environment that may have supported surface life to the frozen, dry landscape observed today.
