The NASA cap is a specific lifetime radiation dose; the Mars trip cost is an estimate of some kind, but they don't specify the duration of the mission. Is 1200 mSv the estimate for the outbound journey, or for both legs, or for both legs plus a 1-year stay on a Mars base?
I'm 68, and I've already had cancer; I probably match the "old man" criterion. But I won't be volunteering to travel through a hostile environment, to visit - a hostile environment. For pity's sake, use robots.
- kwhitefoot 3y ago> use robots. Why not use people who are willing to take the risk?
- denton-scratch 3y agoIt's much more difficult and expensive to get a human encased in a robot to Mars, than to just get the robot there, without the human. The attitude of the human is largely irrelevant (although if you are going to send a human, it seems advisable to not send a suicidal nutter).
- vlovich123 3y agoThere’s a difference between a suicidal nutter and someone who wants to do it because they’re thrill seeking and to make the history books as the first person on mars. Also, there’s a huge qualitative difference between a human on Mars and a robot on Mars in terms of what it means for humans back on Earth. It’s an achievement people will take pride in, can help unify people, & inspires the imagination of the next generation in a way that robots won’t.
