Martian Gullies Explained By ... Sand

eldavojohn writes "There's a lot of evidence that a very long time ago some fluid once flowed on Mars, but the primary evidence of water today — gullies inside craters — is explainable by a much less exotic reason: flowing dust and sand. It would now seem that the news from 2006 that NASA had found definitive evidence of flowing water on today's Mars needs to be comprehensively reexamined. The Bad Astronomer lays claim that flowing sand and dust doesn't explain all recent hi-res imagery from the red planet, but it certainly does seem more plausible, considering what we know about Mars."

YEAH RIGHT!

That's what the Martians want us to think. Next they're going to try and contaminate our precious bodily fluids.

Oh yeah?

Oh yeah, smart guy? Then answer this:

WTF do the Martians drink?

Hi-Res Imagery

[Monkeedude1212]

Have they found the soundstage on mars where they faked the moon landing?

Just get better info

[SnarfQuest]

Take those photos that the various missions have taken of Mars, and use the photo analysis software that CSI uses. You should be able to look at things down to a molecular level then. Even a photo taken with a disposable camera that happened to be pointing in the direction of Mars during a stormy night should be sufficient to determint the location of all water on Mars. They could look at the back side of Mars based on a reflection from one of the stars behind it, so you should easily have 360 degrees of visibility..

nasa FOUND water on mars already!

On no account will a Martian ever drink water, and not without good reason.

This is an incredibly important and urgent issue.

[Anonymous Coward]

I think when we determine, once and for all, that there is or is not water on Mars, then all of human suffering will come to an end. I propose that we increase taxes and spending to their very limits so that we resolve this crisis as rapidly as possible. We should divert all available resources to this matter, including seizing all ore mines and drafting of engineers to support the program. Anyone who shows any potential to be able to do math or computer science should be taken from whatever it is they are doing now and put into training for this endeavor. The people living everywhere from Compton to Harlem; East Oakland to Washington D.C., will rejoice at the wonderful benefits of having finally solved this issue, and for sure will give up all their humble possessions and dreams of escape to a better community to support this effort. In fact, we should declare war; shut down all private industry; seize all assets and take whatever additional measures necessary. A few several-billion dollar programs are not enough. We need massive spending in this area to complete this task so crucial to the very survival of the human race. Contact your Congressman NOW and DEMAND ACTION!

They're definitely doing it on purpose.

Too late! They already have floridated the water!
