re: 4 Approaches for Return to the Moon
Oh - I'm not expecting us to live there right away.
BUT
In the period between 1526 and 1607 - the ability to actually go and visit New York existed.
The ability to visit the moon does not, and frankly, given the solicitations sent out of NASA so far, I dont expect it to in anything like the near-future
That's the embarrasment - we had the capacity to visit the moon, and we threw it away. When Columbus returned from the New World - he didnt scrap his boat.
