Re: Terraforming
Hello ecto -
Please bear with me, as this is important to me, as I invested some time in a science ficiton piece with a terra-formed Mars.
We could free an atmosphere by diverting an impactor, and then create ozone.
I'm not too sure about your early Sun and current million years, and planetary outgassing numbers, as large impacts have happened repeatedly in Mars more "recent" past.
In any case, it isn't the UV that has me concerned, it's the other forms of the Sun's radiation, the kinds diverted by Earth's magnetic field. Could you run those numbers by me one more time, all in one place?
