UM-Bot Posted September 20, 2018 #1 Share Posted September 20, 2018 Scientists have calculated the minimum level of radiation that an astronaut will be exposed to on a trip to Mars. https://www.unexplained-mysteries.com/news/321631/mars-trip-radiation-exposure-levels-revealed 2 Link to comment Share on other sites More sharing options...
Seti42 Posted September 20, 2018 #2 Share Posted September 20, 2018 We should probably develop radiation shielding that works before we send anything other than robots well outside the protective envelope of earth's magnetosphere. 1 1 Link to comment Share on other sites More sharing options...
L.A.T.1961 Posted September 20, 2018 #3 Share Posted September 20, 2018 I don't think shielding is a difficult technical challenge, water can be used but it would add weight to any spacecraft and so it's back to the old problem of launching heavy payloads along with pushing and fuelling a heavy ship.

It ain’t so bad. There are many people willing to take the risk for humanity/the sheer experience of it/whatever floats your boat etc. I’d do it. Would probably have some sperm frozen first though.

Seti42 Posted September 20, 2018 #5 Share Posted September 20, 2018 I'm sure at some point in the future, we'll either develop light-weight and effective radiation shielding, or vastly more efficient propulsion systems where all the extra weight won't matter. We just haven't yet. 2 Link to comment Share on other sites More sharing options...
+OverSword Posted September 20, 2018 #6 Share Posted September 20, 2018 60% of alleged survivable dose (I say alleged because it's going to vary from person to person) No thank you. 2 Link to comment Share on other sites More sharing options...

So just less total trips in space for whoever goes. Not an especially worrying amount for general health. 1 Link to comment Share on other sites More sharing options...

And when they got back they could run for president bringing us to a new low Link to comment Share on other sites More sharing options...

So the total exposure could be 100% + of a total recommended limit. Not sure how that would compare to the risk to life just flying the mission, multiple take off and landings Ect. There are lots of ways to be injured or worse attempting something like this. Link to comment Share on other sites More sharing options...
