The problem with people these days, is your heads are all stuck in the ground, in the present. Economically, the world might be suffering NOW, but the world can still afford space exploration NOW and any new discoveries could be potentially very important for the FUTURE. It is NOT expensive 'willy waving' (how ridiculous) it is vital for the advancement for the human race. Stop whining about the present, how a cup of water is not worth it blah blah blah and think of the future, and the potential life on other heavenly bodies can be the potential to live on other places!! We've only hit a slow patch due to the shuttles being decommissioned
