Kozar_The_Malignant writes "Scientific American is reporting that 'data from the Mars Reconnaissance Orbiter point to vast glaciers buried beneath thin layers of crustal debris.' Data from the surface-penetrating radar on MRO revealed that two well-known mid-latitude features are composed of solid water ice. One is about three times the size of the City of Los Angeles. This certainly makes the idea of establishing a station on Mars far more plausible."

no one is going to be sailing to Mars in a 15th century galleon or caravel. the reason our "New World" is Mars is because technology has advanced a fair bit since the 1400's.
our astronauts aren't going to be stricken by scurvy, nor are they going to contract polio, malaria, or other now preventable diseases. they also won't die form bacterial infections that killed millions of people before antibiotics were discovered. that means a small cut or cavity won't turn into sepsis or bacteremia and kill you.
astronauts are also not at risk of getting lost due to a lack of modern navigation technology. in fact, any trip to mars will likely be backed by billions of dollars of science/research, technology, and years of extensive preparation and planning. and any candidates for Mars exploration or colonization will be specially chosen for their educational and technical background and given additional training on top of that. so they're likely to fare a little better than the average 15th century explorer.
and even people who climb Mt. Everest bring their own oxygen, food & water. why would astronauts going to Mars need to worry about no air/food? if we were going to send anyone to colonize Mars they'd be living inside of a space habitat. they're not going to be dropped off on Mars butt naked without any supplies or shelter. in all likelihood by the time we send our first manned mission there'll already be some kind of habitation module, sustainable power plant, chemical oxygen generator, and usable water supply.
any astronaut going to Mars is going to have a much longer life expectancy than the average 15th century European, much less a 15th century explorer. aside from perhaps the psychological strain, going to Mars would be a cakewalk compared to traveling to the New World in the 1400's.

Then spread the job of getting supplies to Mars. (Score:4, Interesting)
Undoubtedly, the quantities of materiel for a Mars base would be huge. What I can't understand is why nobody is ramping up to spread that job around. Seems to me that there are plenty of companies, states, countries, and so on, who would be delighted to get the chance to spend millions of dollars to have their stuff being used by a Mars crew. And it seems to me that we now know both how to get missions to Mars and how to have them work together.
Why is nobody trying to convince Wisconsin to start their own Mars mission to send five kilos of cheese into Mars orbit along with some clothes from Lands' End and fifteen or twenty kilos of brats and cheese bread? We know that UW Madison has some kickass space scientists and plenty of engineers. Or what about having developing nations pay a fifty or sixty thousand dollars a kilo to get their signature products added to a vessel to then be built and launched by one of the umpty-dozen New Space companies? There are plenty of options. [typepad.com]
The smart thing to do at this point is to start pushing non-federal entities to start their own launch programs to launch their own payloads to Mars orbit where they can either wait for landing instructions (safely a few hundred miles or more from the base) or to be ferried down by some purpose-built vehicle.
Not all supplies are high tech. There is no reason that we need to wait years and years before we'll be ready to send low-G cheese, for crying out loud. The vacuum sealers sold in every supermarket today are more high-tech than the gear used to prepare consumables for the Apollo missions. Thousands and thousands of kilos of supplies would fit into this category. Clothes. Food. Bedding. And on and on. And, frankly, there are plenty of ways to structure the contracts so that Mars crew aren't obligated to use what is sent. Something would have to be pretty damn bad to get left in the cold but there's no reason that option can't be included.
And think about it. This way the logistics work is spread around, too. And the cargos can launch at high-G, travel at near-ambient temperatures in low-atmosphere vessels, and in a dozens of different ways, be a hell of a lot cheaper to send then trying to get everydamnthing shipped in a human-capable vessel. Sending everything in one vessel is like shipping a package by buying an airline ticket for it. This would provide the option of "parcel post".

Fossil water (Score:5, Interesting)
What's interesting to me, is that they mention in TFA that this ice can't have formed recently. The current Martian climate won't allow it. Meaning that the glacier was laid down ages ago when such formations were still possible, got buried beneath the debris, and has basically been sitting there since.
Forget water harvesting, I'm more interested in studying the ice in situ. If there ever was life on Mars (which is independent of the question of whether there's life there now), the odds are good we'd find evidence of it frozen in the glacier. Cold preserves, objects frozen in ice erode slowly, and the living things generally need water to survive.
Of course, anything that ever lived on Mars would likely have been microscopic. I doubt we'd find anything as big as a terrestrial animal. It'd still be the first evidence of life outside of our own planet though, which is a pretty frickin' huge deal.
Re: (Score:3, Interesting)
Since current atmospheric conditions wouldn't allow ice formation (it would just sublimate) -- at some point in the past, Mars must have had a decently thick atmosphere, which probably got blown off by some natural catastrophe -- maybe the crunch-up of the hypothetical next-planet-out (now known as the asteroid belt).
Re:Fossil water (Score:4, Informative)
Our atmosphere is protected by the Earth's magnetic field because it deflects the ionized particles which make up the Sun's powerful solar wind. Earth's magnetic field is produced by the rotation of its liquid outer core. Mars by contrast has a completely solid core and no magnetic field. Combined with its smaller size and lower gravity (about a third of the Earth's gravity) this lack of a magnetic field is the reason why Mars' atmosphere eroded away.
The reason for the "failed planet" that produced the asteroid belt is probably Jupiter. Jupiter's gravity is strong enough to pull material out of asteroid belt on a regular basis. If you combined all of the material in the asteroid belt, the resulting "planet" would be less massive than Mercury.

Re:Fossil water (Score:5, Insightful)
There are a couple reasons I wouldn't expect anything large. The more obvious reason is that, if there were large native lifeforms (plant, animal or what have you), they'd be the first to die off. Generally, the bigger you are, and the higher up the food chain, the harder an ecological catastrophe hits you.
Since Mars hasn't be suitable to most forms of life for ages, and since it seems likely it became gradually less and less habitable as time wore on, it stands to reason that larger hypothetical Martians would be long gone. Small, survivable life forms would stick around a lot longer, possibly even to the present day. The odds of finding something frozen in the (geologically) recent past are a good deal better than the odds of finding anything from a couple hundred million years ago.
The less obvious reason is that I doubt there ever were large Martian lifeforms. There's a world of difference (pardon the pun) between being totally ecologically sterile and being Earth-like, and while I'd wager that Mars probably had something alive sometime in it's history, I doubt it ever got much past bacteria, and maybe simple plants. Too cold for one thing, and too dry. I've seen a couple different theories about how Mars was in the past, but nothing I've read suggests abundant heat, or water, or a thick atmosphere.
Granted I don't like to assume that the standards for life on Earth are the same as the standards for life elsewhere, but since we don't have any other basis for comparison, that assumption will have to stand. Plus, if living things adapted easily to extreme cold and scarcity of liquid water, you'd expect the poles here to be host to a larger variety of life. A world only slightly more hospitable than Antarctica doesn't seem like the best place to find big fauna.
