There is not much economic sense for either and there is no real political pressure for either.

Also the 'pioneer' attitude of the older died in the name of 'liability' and insurance. In Earth terms, our attitude to risk aversion would not allow any Christopher Columbus-like space exploration. We ll get there when its really really safe and unexciting...

I personally find it really depressing that 40 years after going to the moon NASA plans on going to the moon again (but it is gonna take them longer this time despite the technological breakthroughs). Its like watching the remake of a classical movie (i.e they usually suck).
