Why did we get to keep our atmosphere while Mars’ was stolen?
Magnetic field. The dynamo generated by the Earth's core would have to stop for us to lose our magnetic field. This field deflects the charged particles of the solar wind, which would scour our atmosphere.
The Short Answer
Magnetic field. The dynamo generated by the Earth's core would have to stop for us to lose our magnetic field. This field deflects the charged particles of the solar wind, which would scour our atmosphere. This is not something that is likely to occur abruptly. Mars being smaller probably helped it cool and solidify faster, and allows an easier escape velocity for gasses.
