Re: There is still legitimate concern about solar flares
Water has long been proposed as a good solar storm cellar shield for spacecraft. Now that we know that there's ample water likely readily available ON Mars, future Mars bases could water shield their sleeping quarters and some parts of the living quarters. You'd only get your significant rads working outside or under glass viewing domes. And as we see, likely doses would be under a couple % of those received by US radiation workers.
I still wonder if the 1st post has a decimal point wrong.
