0:00 / 2:00 Sputtering: Mars Atmospheric Loss - MAVEN (American English)
1 year ago
When you take a look at Mars, you probably wouldn't think that it looks like a nice place to live. It's dry, it's dusty, and there's practically no atmosphere. But some scientists think that Mars may have once looked like a much nicer place to live, with a thicker atmosphere, cloudy skies, and possibly even liquid water flowing over the surface.
NASA's MAVEN spacecraft will give us a clearer idea of how Mars lost its atmosphere, and scientists think that several processes have had an impact.
One way a planet can lose its atmosphere is through a process called "sputtering." In this process, atoms are knocked away from the atmosphere due to impacts from energetic particles.
