Rover Finds Ancient Streambed On Martian Surface

sighted writes "NASA reports that its Curiosity rover mission has found evidence that a stream once ran vigorously — and for a sustained amount of time — across the area on Mars where the rover is driving. There is, of course, earlier evidence for the presence of water on Mars, but NASA says this evidence, images of rocks containing ancient streambed gravels, is the first of its kind."

Probably never occurred to those rocket scientists and geologists at NASA. :)

It sure beats sending 2-3 meatbags

I believe those meatbags are commonly referred to as: "Ugly bags of mostly water"

I take it you've never heard of Occam's Razor. Given the composition of Mars and other evidence gathered to date water is by FAR the most likely substance to have caused this.

I bet it was Florida Orange Juice. Prove me wrong!

I've never heard of Occam's Razor. What is it? I'm imagining some kind of 7 legged, supersonic, invisible shoe.

It's an Olde English Cellphone.

Orange juice is mostly water, so water is still the correct answer.

Human beings are mostly water, so I guess we can explain Mount Rushmore as "water erosion"? ;-)
