Undertoad Tuesday Nov 25 02:19 PM11/25/2003: Rivers on Mars redux
Was there flowing water on Mars? Scientists think yes, though not because of the "canals" that some people used to think might be evidence. (Trying to remember: was this ever taught as a working theory?)
This image serves as proof to the people who work on such things, that Mars not only had water but "meandering" water. The delta pattern seems to be the standard sort of delta that might occur after a river deposits stuff over time.
So, are we looking at a Martian Louisiana of millions of years ago? (Would there be Martian Cajuns? Would they look like James Carville?)
The full story. (And thanks to whomever sent me this one...)
(This image also fits into the "Earth as Art" category, except that it's Mars.)

Bill S. Tuesday Nov 25 04:26 PMmaybe its a bad case of acne on a dogs ass.
Riddil Tuesday Nov 25 05:13 PMI've never understood the real *reason* behind arguing whether or not Mars had running water. It seems immaterial.
I believe I read somewhere that even at the poles which have frozen water (and a few frozen gases, to boot), that in the "martian summer" it will actually become warm enough for some of the ice to melt. At which point it goes directly from solid ice to a gas, since the atmospheric pressure on Mars is far too low to sustain water in a liquid form when it becomes that warm.
If that statement is true, then for there to be running water at that magnitude it would mean that Mars at that time would have had to have a much higher atmospheric pressure... something difficult to do considering the gravity of the planet can't really sustain a dense stratosphere.
(Of course, my entire argument is based on the bits I remember from HS science courses and a smattering of knowledge I gleaned from my college meteorology course... when I was actually awake. Sadly enough, considering how infrequently that was and how long ago it was, it should be noted that I'm far from an expert in the field)

So, are you a Biology teacher? If so, how do you like it?

They had it all and then they invented SUVs.
Nothing But Net Tuesday Nov 25 11:01 PMI just happened to notice that if you exchange "Poland", or variations, for "Mars" in Riddil's post, it still makes perfect sense!

Funny, PBS just had a show that discussed this. There's some concern that the Earth's magnetic field is flipping. (The field acts as a planetary shield, deflecting all the crap the sun keeps sneezing at us.) In about a thousand years, the north pole will be in the south, and south in the north. In between, we'll have lots of mini-poles wandering around, confusing whole generations of cub scouts.
While analysing the Earth's mantle, they discovered that it's fluid state is key to the magnetic field. They theorized that in the distant past, Mars may have had a thicker atmosphere, with running water and happy bunnies. But the core cooled too much, and its field faded, and the solar wind blew most of the atmostphere away.
Shields up! Anyone know if Santa is polish?

You're almost there, dude. Keep following the clues.
Uryoces Wednesday Nov 26 02:38 PMWe might want to terraform Mars. Basically, we release greenhouse gases into Mars' atmosphere, and increase it's ability to trap heat. The theory is that the carbon dioxide could be liberated from the poles and the soil, and that plants would be able to convert it to oxygen for our use.
Robert Zubrin is an birlliant, inspired nutbar who could be considered an authority on Mars.
Whit Thursday Nov 27 04:34 AM Also, if there was water on the surface there is a greater chance of water being under the surface at a point where we could pump it out. Which would make a manned Mars landing far easier.
onetrack Monday Dec 1 09:01 AMIt can't possibly be Mars .. I can't see any Martians waving .......
Another thought ... if they landed a spacecraft there .. and it promptly sunk outa sight in a Martian version of a Louisiana swamp .. at least all the space experts could cry .. "we were right!! .. all the while, lamenting the loss of the spacecraft that could have given them more vital info .. like how deep the water was ........
xoxoxoBruce Monday Dec 1 06:50 PMWell, they would know it's deeper than the ship is high.
Welcome to the Cellar onetrack. We can always use another smartass.
Hubris Boy Monday Dec 1 10:08 PMThe Martians were probably saying the same things when Carville's ship crash-landed in Lake Pontchartrain.
Bill S. Tuesday Dec 2 12:31 PMyes juju. I love it. But back to the real issue...running water on mars. Without it ... no flushing toilets, hence outhouses. but you can't have an outhouse without a sears and roebuck catalog. No catalog no butt wipe, no butt wipe no close friends. a real problem for astonauts. Hmmmm.
Bill S. Tuesday Dec 2 12:50 PMWhat the hell is a carville? A town for cars? A nut infested candy bar?

When you lift up a rock, you find a bug.
When you lift up Clinton's butt, you find a Carville.

What's next? "The Simple Life II: Paris & Nicole go to Mars"?
Bill S. Tuesday Dec 2 03:25 PMHow 'bout " Debbie does deimos?" or "Attack of the giant carbuncle from phobos" or "Miniature demon of deimos found as prize in box of cracker jacks"." or lizardman with scar that looks like a profile of Bill Clinton on his ass, invited to dinner at White House?
HungLikeJesus Sunday Mar 16 11:44 PMWho were all of these people, and where have they gone? Just like water on Mars, they were here and left some evidence of their passage.
Few remain.

No. James Carville is a golem. Not a Martian.
