Would you go to mars knowing you may or may not ever return to earth? I'm just curious what other people Would do if they had an opportunity. Just saw this: http://www.iflscience.com/space/nasa-astronauts-will-head-mars-mid-2030s
I dunno if I would go if there was no chance on coming back to earth. Then again under the right circumstances I might actually consider it. It definitely would be interesting going to another planet with slightly less gravity.
