One of my main concerns regarding a manned martian research station is that I have heard no serious consideration of the amount of radiation humans would be exposed to on the surface and in transit. How would your plan address this issue?
In transit the radiation levels are somewhat high, but once you're on Mars even without any additional radiation shielding its not too bad. I think a 500 day Mars round trip (no radiation shielding) is estimated to be in the 1 Sievert area, the recommended lifetime exposure for an Astronaut (~3-5% increased cancer risk). A vast majority of that exposure is from the Earth/Mars transit. On the surface the levels are about the same as you'd experience on the International Space Station. Even putting in pla
