Can oceans of water form without protection from chaffing solar winds? I hope we can see a Martian fossil in our lifetime, much less a Martian shrimp living under ground now. I bet they are delicious. Did Mars have a deflective magnetic field once?

Which in turn is due to the core not being like Earths or it being to small to sustain the planet. It is difficult to say but it could be due to the size of Mars that leads to the core being the way it is. I often wonder if Earth did not have the collision with planet Thea we would be in the same position today.

The current pressure and temperature on Mars allows for Ice and vapor, but not liquid water, so the permafrost evaporates instead of liquifies. The lack of a strong magnetic field means there is little protection from solar winds. So the water evaporated into the atmosphere which was blown off into space by the solar winds. Jeff.

I wonder what the size of Mars was then…and what its gravity was…if it still had its magnetic field

then the other interesting question is…whether there is anything that could be done to terraform mars back into something similar and thus more liveable?
