>IIRC Mars lost its atmosphere due to solar winds and lack of good protective magnetic field Someone in the know correct me if I'm wrong, but I believe this is no longer the main theory, as solar wind ablation is too slow to make such a huge impact. I believe the popular explanation now is that geological reactions, i.e. gas reacting with rocks and being sequestered, played a larger part. |
