Interesting bit at the end with the spinning Mars turning into a transformed planet.
How would we go about solving the problem of a new magnetic shield for the planet, that is going to take some creative thinking surely for the people of that era. Else the atmosphere would just leak off.
Heat it a up a little and see what water appears, eventually. 100's of years I'm guessing.
