Yes, the possibility of travel to the moon is real. The humanity can get it. But I think that it is more expensive, and the countries would put out this money in other facilities.
I would not go, there are more things in the earth to see and don't travel to the moon. I wouldn't enjoy of this travel.
The space travel in general is useful for the tecnology and comunications in the earth. Advanced in the telecomunication and the science for know about the earth. But if we made this travel for to see if there are live in others planets, it isn't useful.
Yes, I say that the money spent in these travels would be more useful waste in other things.
