The GAO in the past has said in the long run NASA has stimulated more tax revenue than the NASA budget.

What do you do about sex?
Abstinence my dear fellow. Abstinence.
Why would they need abstinence? I see no problem with sex in outer space or on Mars or the moon.
You have not socialized much.
Starting at puberty the sex drive is always there until we die, with ensuing conflicts.
If you gave 10 guys and 9 girls and one guy is left out of sex what harpoons socially?
What happens if a guy becomes abusive and aggressive?
And then there is religion. Is somebody excluded for being an Evangelical who wants to spread the gospels around the solar system?
Who wants to spend two years in a confined space being preached to?
Do you exclude a conservative Muslim who opposes fornication?
If we go to the Moon and Mars we inevitably bring all o0ur social issues.
