The bottom line is that the extremely thin atmosphere on Mars, and the absence of a strong global magnetic field, result in a complex and potent particle radiation environment. There are lower energy solar wind particles (like protons and helium nuclei) and much higher energy cosmic ray particles crashing into Mars all the time. The cosmic rays, for example, also generate substantial secondary radiation - crunching into martian regolith to a depth of several meters before hitting an atomic nucleus in the soil and producing gamma-rays and neutron radation.
Why not just colonize the moon? A lot closer, and same issues.
So oh yeah, Musk Fluffers! Go ahead and drink the Flavor Aid....join the colony and D-I-E.
HeadSet saysWhy not just colonize the moon? A lot closer, and same issues.I believe Mars is much closer to the earth's atmosphere and has many more minerals and potential of water compared to the moon. I think they say it is actually easier to land on Mars than the moon - other than the longer journey.
long term radiation sickness for almost anyone deciding upon Mars.Venus has no magnetic field, so radiation may still be an issue.
Oddly enough, given Venus's atmosphere, its ionsphere does interact with the Solar winds to generate a type of slim magnetosphere.
If you watch the opening to the Expanse series (on Amazon Prime) to can see lights in the canyon walls
The moon is a much better bet. Not only is there a permanent dark side
It's called the dark side because we never see it. Which also helps to make it the ideal off planet launch pad. The moon always shows the same face to us while the rest of it faces the universe.
The thrust seems minimal, maybe 1/100th of a G, but it is constant and can be maintained indefinitely with a nuclear reactor on board. Constant thrust builds to significant velocities over time, which would allow us to make much longer journeys in a fraction of the time.
I don't foresee colonies of people living on Mars ever. It will probably be more like small outposts of scientists like we have in Antarctica.
