Water is a heck of a thing, about a foot of it will stop most cosmic rays, and you can drink it as well
Turns out we are made of it, and will need to carry a lot of it with us, even with recycling, so simply placing the water storage between the crew compartments and potential sources of cosmic rays will eliminate this concern
Yippee!
In regards to our adaptations for gravity, we need to confirm that we can tolerate centripetal 'simulation' of gravity for journeys, and
I am pretty sure you will find volunteers for this thing
The simulation of gravity becomes unnecessary when we get ships capable of sustained 1G thrust, and that also drive travel time from/to Mars into weeks, making Mars a two-way destination
