It's official, Mars has water

Very interesting

Great, I'm thirsty.

[widgeon13]

Can we run a pipeline to California??

[sammyg2]

15 minutes ago Moonbeam brown proposed a new price hike on that supposed water.

The brine hypothesis could also indicate a gigantic oyster population on mars.



...I say attack!

So when are you leaving?

[kach22i]

They found a way to derive data one pixel at a time.

I think they need to get a probe down there, what if this new way of looking at data is flawed?

On the TV this morning they were hinting this would be in the NASA announcement.

From the article ...

"The spacecraft detected magnesium perchlorate, magnesium chlorate, and sodium perchlorate, which really don't make the best food additives"

Oh really now? Since when is it not up to Monsanto to decide what makes the best food additives, versus Popular Science?

It's far from certain but IF Mars has flowing water that changes everything.
A permanent colony suddenly becomes viable and almost easy.

This is huge! A brand new revival of Space Exploration. We'll be there before you know it.

Seems pointless though, existence in a sealed colony only to be interrupted by brief sessions in an environment suit? Also worthy of mention is "Prairie Madness" experienced my our first homesteaders in America.

Not my idea of a good time, water or no water.

[fanaudical]

I thought that the atmospheric pressure on Mars was too low to sustain liquid water?

[Gogar]

From reading these news reports it seems to me that mars has "liquid," not necessarily "water." It gets more traction if you say "water," though.

[A horse with no name]

It's still only just about what little green Martians eat...Cheese, but now it has melted.

[jyl]

Sounds like water with so much salt that it is, essentially, antifreeze.

Ah, fresh (raw) oysters. NOW I'm interested in Mars.

I'm sure it would be challenging.
Regardless I would go in a heartbeat however I'm sure there are vastly more qualified people than me willing to do the same.

I can think of no better way to spend the remaining years of my life.

That an was educational read.

I wonder if the Internet and social contact though it would be enough to fill in the void.

Also a Mars colony may not suffer from isolation, but rather too much contact and not enough personal space in cramped quarters.

Interesting host of challenges.

The Salt Fog and Salt Spray Testing industry may be booming soon.

FYI: An interesting thread from just a few months ago.

Could low altitudes on Mars support liquid water?

NASA Confirms Evidence That Liquid Water Flows on Today’s Mars
http://www.nasa.gov/press-release/nasa-confirms-evidence-that-liquid-water-flows-on-today-s-mars/

These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of the dark streaks are thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona). Vertical exaggeration is 1.5.

Dark narrow streaks called recurring slope lineae emanating out of the walls of Garni crater on Mars. The dark streaks here are up to few hundred meters in length. They are hypothesized to be formed by flow of briny liquid water on Mars. The image is produced by draping an orthorectified (RED) image (ESP_031059_1685) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona). Vertical exaggeration is 1.5.

No, they found the evidence of a high salinity brine (where salinity has much to do with perchlorate salts of alkali and earth alkali metals) occuring seasonally as wet streaks on some slopes.
It's basically a very saturated solution, surface phase, coupled to hydrated minerals.



No evidence of surface running water or aqueous solutions exist. Not even mud burps, as I like to call them, although these might exist seasonally in the lowest regions.

I'd describe these as taking some calcium chloride powder and sprinkling it on a rocky desert slope. It will absorb moisture and that highly saturated solution is gonna wet the dry dirt and make it optically darker.

And this is not news. This is a PR stunt of an organization struggling with rednecks in the Congress that decide how much money it gets.

Cull, S. C. et al. Concentrated perchlorate at the Mars Phoenix landing site: Evidence for thin film liquid water on Mars. Geophys. Res. Lett. 37, L22203 (2010).

We knew about these liquid films and voila - there will be a streak if you do it on an inclined plane.

Have we all been suckered as lajoswinkler claims?

Motion's other thread has me thinking:

KC's Mars water....eleventy-three million dollars per bottle!!!

Supplies are limited....don't be thirsty my friends

My son expressed the same sentiment recently.

At the time I thought he was nuts.

After thinking about it, I still do.

can you really afford to pay your way all the way to Mars? That's pretty expensive trip.
I'm sure you weren't referring to wasting EVERYONE ELSE'S money to do it.
