we need some incentive to go into space. And what's more we need an incentive to really go into space and not just in lower earth orbit to drop some satellites, or deliver a cargo of nuts and bolts for the spacestation.

what might this incentive be? I have no clue, but it should be a good one and the fact that I can't think of one should tell us something.
 
While wet1 is no doub correct (read his last 2 posts)

Let us face it: We simply do not have the tecnology, Yet.

M.J.
 
And why don't we have the tech yet? Does tech just magically appear? No!: Money needs to be invested to make technology happen!

We have 95% all the technology to go to mars we just need the $50 billion to make it happen.
 
Well, Fetus... I'm sorry but I can't totally agree on the Mars idea yet. We don't know how to send humans to Mars without saving them from the three most dangerous effects of long-term Interplanetary spaceflight...

1) Bone brittleness
2) Muscele loss
3) Radiation

Sure, 1 and 2 might be solved by figuring out how to produce artificial gravity, but we have yet to test this out in space by building and operating a prototype artifical-gravity producing spacecraft. The 3rd is even more serious... while we can protect them from Solar Flairs, we don't yet know how to shield them from the background radiation which destroys DNA... and on a Mars-length trip you can end up with extreme health risks as a result.
 
You should read the book: The Case For Mars by Robert Zubrin. Its got all the answer you need in there... again we could do it if only we had the money to refine the technology.

1&2: Synthetic gravity was planed in both Mars Direct and NASA’s Mars reference mission and involves the use of nothing more then a spent booster and a km or 2 of of Ultra fiber cabling.

3: Estimated radiation exposure for a 2 year trip to mars and back was ~60rems. 75rems in one second don’t even produce any side effects on a person! So 60rems over 2 years is nothing! Here on earth people (at see level) get only .2rems over 2 years… .6rems if you live on a mountain and 3rems if you spent 2 years on a plane.

People are beginning to realize that space travel isn't after death only?Lord willing, we can enjoy the midst of it's majestic beauty, from a heighten state, in this form. The lust to discover it's secrets yearn in each of us.Just the thought of Deep space travel, turns the heads of many, from all walks of life. NASA realizes it needs to go back to the drawing board, and combine the fields of technology, while capturing the imaginations& input of a zealous public as well.
