Financial talk

I'm not necessarily against exploring the unknown, or exploring even the known, but it just surprises me. With everything happening in the US. With all the financial problems. Is now the time to spend Billions of dollars searching for water on Mars? I'm not trashing NASA. I firmly believe in progression. But isn't there a better time? Will Mars really change that much in, say, twenty years? What do you think? There are a lot of different drops in that big bucket of budget, I agree. Some smaller and some bigger and fatter. But a Billion is a Billion. A Billion could do a lot more good than finding water on a planet where no one lives.
