Yesterday, an excited rumour started spreading in the science community (and quickly the web community) that NASA was about to confirm an astonishing discovery on Mars. And boy they didn't disappoint.
The best evidence yet of flowing water has been discovered on Mars. Not frozen stuff on the polar caps, not frozen deposits deep underground, but flowing surface water.
"The shapes of these deposits are what you would expect to see if the material were carried by flowing water," said Michael Malin of Malin Space Science Systems, San Diego. "They have finger-like branches at the downhill end and easily diverted around small obstacles."
Sadly, the Mars Global Surveyor has not communicated with Earth since November 2, suggesting that it's suffered a power failure. Both the Mars Reconnaissance Orbiter and the Opportunity Rover have been unable to contact it either.
