Not according to the papers.
- cogman10 6y agoWhich papers? That's really counter intuitive to me. I'd expect that a higher atmosphere concentration would have a higher rate of loss because the solar wind would grab more of it. Does this mean that mars is losing atmosphere faster today than it did 500million years ago? That's really fascinating!
- JoeAltmaier 6y agoCan't find it now. Curiosity has an instrument to measure isotopes, which tells how its air chemistry changed over the aeons. It showed disparity in heavy vs light gasses trapped in rocks of different ages. Light gasses are lost first, so that gave a clock on atmosphere loss. And a profile of that loss over time. Here's a sunday-supplement summary I did find: https://science.time.com/2013/07/23/revealed-how-mars-lost-its-atmosphere/ https://science.time.com/2013/07/23/revealed-how-mars-lost-i...
