Shields up: New ideas might make active shielding viable
Active shielding was first proposed in the '60s. We’re finally close to making it work.

That's all absurd, cramming a crew into a tiny dark cylinder, deep
inside tons of magnets, to reduce their radiation exposure a little.
Space is not people-friendly. Earth is.
Staying on Earth just because we evolved here would be even more absurd.
Traveling to or living on Mars would be lethal. Living on the moon
would be bad too.
Travelling to Mars might be dangerous. but living there would be fine, once we'd engineered a safe environment for people to live.
We might well be able to engineer people who could live there safely - evolution has yet to come up with an error-detecting genetic code that lends itself to error correction. but intelligent design could do better.
