In Oct 2010, NASA claims to find water on Mars, or did they? Here’s the story: Discovery news (link). Notice the wording: Mar Rover Spirit finds “evidence” of water on Mars.
Next claim: Mars rover finds “puddles” on the planet’s surface (New Scientist Link). Then there is an update on the page that says: Update: The researchers have retracted their claim about the possibility of standing water on Mars after readers pointed out the terrain lies on the sloped wall of a crater. It takes readers from a blog to point out NASA’s mistake? Or maybe attempted deception? Why deception? Well there is about a trillion dollars involved in sending a manned space ship. That much money can corrupt most people.
No oceans, flowing streams, waterfalls? NASA is ready to commit to anything as evidence for water on mars, and here’s why:
They have already committed to oceans of water being on mars. Spent money to animate it, and they want to spend a trillion dollars to send a manned spaceship there. So there is a lot of grant money involved in selling the idea to the public and to the government. But selling is not proving. Anyone can animate an idea to sell the idea, but only finding evidence of what could have been on mars, is not proving what has been on mars.
