All this talk about heading to Mars by various peeps/orgs. Have they measured/evaluated the (sun) radiation exposure after leaving the Earth's magnetosphere?
I'm thinking LOTS of gene damage by arrival. Guaranteed death by cancer of some kind. (Rather than age.) : /
Smarter to wait for gene-repair medical tech to get online before hoppin' to another planet.

Yes. This is what I ponder in the calm moments of life.
Much later edit: I found a PDF done by NASA detailing the radiation exposure of such a trip. (And the recommendation that any colony would need underground quarters, as a form of shielding/protection from the sun.) While not a guarantee that there will be 'death by radiation' the exposure is high enough to make cancer at an advanced age almost a certainty. : (
