Underground Water on Mars?

WaltonNews wrote in with a story about possible underground water on Mars. The article begins: "The Mars Express spacecraft, from the European Space Agency (ESA), has indicated to scientists that the dry atmosphere and surface on the planet Mars does not necessarily mean Mars is dry underneath the surface. In fact, a huge storehouse of water and carbon dioxide could be found in underground reservoirs."

Re:format

[OriginalArlen]

I have a deeply unpopular opinion round here which is that, even if humans actually walk on Mars in our lifetimes (I'd put the chances of that at 5/1), the chances of any permanent settlement are nil, zip, zilch, nada. You have to understand how much it would cost, and that there would be no economic benefits at all apart from the teflon/tang/spacepen type spin-offs; and if that's the aim, there are plenty of much more useful projects that could be run which would have just as many technological spin-off benefits. You have to understand how hard it would be to get there and maintain life support in such a hostile environment. How long would the US settlers have lasted if they'd had no natural resources apart from lots of very very salty / acidic dusts and regolith, a dim sun, low gravity, and had faced instant death in the event of a loss of air pressure / failure of any of several thousand literally "mission-critical" systems? Oh wait, for some of those failure modes, death would be slow, lingering, and unpleasant. And we'd all have to watch it on TV every night. *shudder* no, thanks.

Of course that's not the aim. The Moon will be more than enough of a technical challenge. The reason to go to Mars is pure science; to explore, and in the (very) long term; to colonise. Any economic payoff, unless we discover abandoned Martian flying saucers, is likely to be centuries away, no one is pretending otherwise. (Well, maybe Zubrin is.)

Re:format

You know, I was going to write a long post debunking your opinion. But you know it's unpopular, so why ruin your day and waste my time debunking you?

I'd suggest, however, you reads "The Case for Mars" by Robert Zubrin. He lays out a, well, case for going to Mars and explains why it won't be nearly as expensive as not going.

Even in the relatively temperate climate of North America, there are plenty of ways to die.

Regardless, I've actually thought along the same lines about colonization, and it has a lot to do with the economic rationale for going in the first place. Once there is one good reason to establish a population, everyone else follows to support that population. Columbus thought that we'd settle to get gold and silver, at Jamestown it was tobacco (eventually), in New England and Atlantic Canada it had a lot to do with just leaving Olde England and perhaps a very little to do with cod fisheries and fur trading. But once those settlements started, other economic activites were established to support the local population.

Once it becomes cheap enough to visit Mars with regularity, be it for simple science or tourism, it would actually make sense to establish a permanent base, rather than bringing everything along each time.

Re:format

[WindBourne]

Actually, your opinion matches up with a number of folks. Of course, most of them believe that ID is real.

Thank god that it is not likely to win. Simply put, it is no where near as expensive as NASA or even you believe. Why? Because of NASA's and RKA (USSR/Russian space agency ) precursor work of figuring out what works.

1. Launch will be provided by any number of transports. My belief is that spaceX and scaled composites will capture the bulk of this within another 4 years.
2. Bigelow's stations will be used for transport (100 million or so) nearly 100% based on NASA's work.
3. And then a modified BA-330 will be sent to the martian surface by 2015 to see how long it will last. (and yes, the BA-330 will be out by 2010 because of DOD's needs (they are going to use them to hide where antenna are pointing as well as provide a short sleeve work env for repair)). If need be, then craft will be put in a metal container to keep off the environment. (hopfully, one of the next surface missions will send some small samples of material to see how they really survive).
4. Armadillo's craft will be used for hopping around and doing mining on the surface.
5. Modified forms of Lunar suits will be used for the martianaughts.

No, your fears are trivial to get past.

The one hard part on all this is, power. We have 2 choices; Nuke or power sat. If NASA has a decent low-weight, high-power generator, then we will send that. But it is probably good for only 30 years and will probably not be easy to move. Of course, we could send a power sat and then beam the power down. But how much power?

In fact, baring war or worsening debt crisis (sadly, this is highly likely), I believe that we will be on the lunar surface by 2015 and mars by 2020.

And you'd be spending your life building a new world.

Insofar as a corporate/government owned industrial complex outside the legal jurisdiction of Earth bound society is a "new world," sure. See, there is one huge difference between pioneering in space and pioneering on Earth. On Earth, anyone could set out and claim land on their own and live by their own means. On Mars, there would be no "on your own." The ONLY way you're going to survive on Mars is through significant investment by Earth bound corporations and/or governments. And once you're there, there may be no way back if the powers that be don't want you to go. So, if you like the idea of being a slave, have fun.

Difference between settling North America and settling Mars is that just about anyone could get on a boat and travel across the Atlantic. In fact, many poor people did exactly that. I'm not saying the journey was always pleasant, but it certainly didn't require too many resources. And once there, you could conceivable live by your own means. On the other hand, nobody is going to Mars without very significant backing from Earth bound organizations such as corporations or governments. And once you are there, the organization that sent you there pretty much owns you. Going to Mars would be anything but an escape from "Olde England." You'd effectively be a slave.

It's not extrapolation. (Nor was it my analogy in the first place) I believe that once the cost of the trip is reasonable, people will choose to stay on the other side. What you are saying is that the cost will never be reasonable. This is like--to continue the analogy--stating that in 1493, that no average joe will *ever* sail west across the Atlantic, and that every voyage would need to be funded by royalty. So it took perhaps 130 years before that was not true... so? I agree that the cost will be prohibitive for a long, long time. But that doesn't mean that it will always be.

Re:format

But we can do an awful lot of science without humans, for the forseeable future anyway. How do you quantify whether it's worth spending $200B for some applied science that's not going to tell us anything of direct relevance to us here on Earth? I've been following the MER rovers for the last three years, watching the raw data at the Exploratorium - there's more raw data from those two rovers than there are planetary scientists available to work it over thoroughly. There's plenty of stuff these rovers can't do , of course, and personally I'm looking forward to seeing more and more fantastic science from the surface of Mars in the years to come.

Lots of O2 up there. Lots of iron that is easy to work with.

The payoff in this case depends greatly on initial funding and even more so upon sticking with the damned funding for it in the first place.

Moving one of them to where we want it is a much less daunting challenge, initial resource expenditure-wise, than lifting the equivalent materials out of Earth's gravity well.

I think the point of the research being referenced (though the link is bad, so its hard to tell) is that new experiments show the water loss rate should be much lower than they previously thought, which means all that water that used to be there must have gone somewhere.

This isn't about the occasional seeps, it's saying that there may be vast quantities of water locked up because water is being lost much more slowly than previously thought.

There's nothing new here. Stating a theory that perhaps less water has disappeared than previously thought? What's expected? Ice is known to have a lower planetary dispersion rate.

To add to all of this, it's scientifically reasonable to assume there should be fairly large quantities of water under the surface. Logic applies, we've seen landforms that support the belief of water having once been on mars, and we've got recent pictures to show some (likely a lot) is still there. Guess what, anybody who knows anything about dessert geography also knows that water naturally burrows below the surface. This is just putting 2+2 together.

The permanent Martian polar caps are water ice. In the winter hemisphere they get bigger because of the CO2 ("dry") ice on top of the water ice

Detecting Aquifers on Earth

[PowerEdge]

Can NASA satellites or other satellites currently orbiting Earth detect our Aquifers? If so, perhaps the same instruments can be used on a probes sent to orbit Mars. If not, perhaps they should determine the method of detecting Earth's groundwater first, from orbit, and then export such tech to Martian probes. Just my 2 cents.

Re:Detecting Aquifers on Earth

Yes, that's already done. However, it only works in places like the Sahara Desert, since the dielectric constants of sand are low, and the frequency of radio waves can pass deep through sand (like GPR). Mars has low dielectric constants, I think.

Maybe the article was about the gullies

[exp(pi*sqrt(163))]

I recently attended a presentation by a geologist (areologist?) investigating the gullies. She argued convincingly that many of these are caused by liquid water erupting horizontally from aquifers about 100m underground. This water would lie about 100m below plateaus and the water would emerge from the side of steep faces. This is exactly where the gullies appear in photography and the 100m is consistent with the pressure and temperature required to keep wtar in a liquid state. On emerging to the surface the water would only last a few minutes before boiling and freezing. This is consistent with the length of the gullies. From what we know of the temperature of Mars these conditions aren't suitable for liquid CO2. The sinuosity of the gullies is inconsistent with landslides.

This is quite different from evidence from radar. We're talking about water that may have flowed in the last couple of years. (Not geological time. A few years here means less than ten.)

I'll take a one-way mission, too. Hell, imagine never having to wear bug spray anymore. No more poison ivy. No more dimwits trying to push their religion on you by force if necessary. And you'd be spending your life building a new world. That would be a wonderful place to die.

How much fresh water, oil, and labor do you think it takes to just keep you fed? To supply you with clothing? To make a single computer chip? There are no supermarkets on Mars, no Chinese sweat shops, no Best Buy. In fact, those "dimwits" you want to get away from will control everything you do, say, and think; if you don't comply, they'll just stop sending supplies.

If you want to "build a new world", try getting yourself a plot of land in the north of Canada and living off the grid: the government will leave you alone, and it will be paradise compared to Mars.

[Paulrothrock]

Yeah, because people walked around naked and hungry before we learned to tame the wild supermarket and shopping mall.

Again the same baseless claim

[Anonymous Coward]

Over and over we have to hear how water is probably on Mars.

How about just waiting for the story that says "yes, we found it".

It is like listening to the "W" tell us how we are winning in Iraq.

Total Recall

[mpv1145]

I agree with most on this topic that this is extremely old news. Several years ago Arnold Schwarzenegger was able to locate that thingamajig that penetrated that whatchamacallit, which instantaneously spawned a new, Earth-like atmosphere. Now there are trees and grass and bodies of water and snow-capped mountains and clouds and all sort of other nature for us all to enjoy... Don't you remember? I mean, his eyes are still a little bugged out, but for the most part he is back to normal.

Old News. Pass it on.....

Proving by disproving

[heroine]

As in many other things, it's now common to prove things by disproving everything else. Now by disproving the existence of any water on the surface, they're convinced of a huge storehouse of water underground.

They just keep on hoping

[Nom du Keyboard]

They just keep on hoping. We haven't found any sign of it anywhere yet (secondary evidence like erosion channels means little unless you actually see them being created), so let's say it must (might) be here where we can't look at all yet. Impossible to prove a negative.

Re:They just keep on hoping

[Anonymous Coward]

Have you completely missed the evidence gathered by the rovers? They actually pretty much proved that there was once huge bodies of water floating on the surface of Mars.
Then there was some recent news about the nasa Mars orbiter finding evidence that suggest that there has been some outflow of liquid somewhere between 2000 and 2005, which at the moment can only be explained by liquid water. They actually have a photograph from before and after the eruption, so that is pretty damn close to witnessing it.

We're gonna need a bigger magnet

[ChromeAeonium]

Yep, the obvious makes Mars pretty unfriendly, but I think the biggest problem mankind would face would be the radiation. Good ol' Earth here is set up with a convient magnetic field that keeps the solar radiation out. Mars doesn't have one of these. Even if you can, say, terriform Mars to have a breathable atmosphere, get a greenhouse effect going to make it warm, ect., the lack of protection from the solar radiation would strip it all away in time, and boil all the water to vapor, which would also be stripped away. Sounds fun, altough if you have the ability to terriform a whole planet, I suppose a planet wide magnetic field wouldn't be that much harder to pull off. The other option you'd havewould be to live in a bubble with a self-contained environment and radiation protection, and we all know how good humans are at living in peace with limited resources. Rather than eyeballing Mars, its probably a better idea to hold off a century or two to ensure Earth continued habability.

History of Mars Water

[Tablizer]

1973: There MAY be water on Mars.

1977: There MIGHT be water on Mars.

1997: There is POSSIBLY water on Mars.

2004: There is PERHAPS water on Mars.

2007: There COULD be water on Mars.

I am beginning to see a trend here, but I can't quite put my finger on it.

Same shit, different planet

[ChromeAeonium]

If you plan to take any other people with you, that dream goes out the window. Sure, there might not be any bugs o poison ivy, but there will still be people, and that means dimwits trying to shove their religion down your throat and wild-eyed theophobic dimwits. In other words, same shit, different planet

Re:Same shit, different planet

[Paulrothrock]

That's the great thing: The folks who I'd be going with will be like me. Sure, some religious freaks might go, but they'll be on the other side of the planet.

I'll just have to make sure I land on the western hemisphere, cause it's the best one.

Of course there is....

[zoltamatron]

Of course there is underground water on Mars......don't you remember Total Recall? The guvenator has known about this for quite some time.....
