"... suggesting that the planet once had a humid, rainy climate, according to research published Monday."
I'm having a really hard time believing scientists lately. I'm a thorough believer in science, but there is absolutely nothing unscientific about skepticism toward the human beings who call themselves scientists. As such, they are tempted to serve their own interests over — and tapping the power of — the high ideals they espouse. Climategate is rubbing my skepticism raw, and this Mars story hits me in a tender spot.
It's just so useful for there to be plenty of water on Mars. I think of all the money that would flow — like water — into the hands of the Mars scientists if there were a mission to Mars, and the existence of water — plentiful water — is a fabulously powerful incentive to undertake that mission.
