"Do you think landing on the mars and disovering ice will help us redirect or destroy deadly asteroids?" Going to space certainly will help if that's what you want, and there are projects that address this problem specifically.
"Do you really think the possible impact of an asteroid is a serious threat to mankind?"
It's a serious, but unlikely threat, it will happen again, perhaps not soon, but we should probably learn to deal with it at some point don't you think?
"So your point is: Money doesn't matter on earth, but going to space is important??"
No, I think money is important on Earth as well as in space. I think spending 0.6% of the US budget on doing enlightening and inspiring things in space is justifiable.
