That's just a theory. Also, that frozen water-ice is mized with frozen carbon dioxide-ice. If you think accessing that water's going to be as easy as a colonist scooping some up into a bucket, taking it into the habitat and melting it on the stove, think again. The carbon dioxide-ice will evaporate, form a gas, and pose a serious hazard to health and life in the airtight habitat with minimal air-circulation and purification.
>It can get over 32F... Did you just see 32 and assume it as a relatively big number? 32F is 0C, where water freezes not melts. That water on Mars will still be frozen near the equator where a planet like Mars is warmest.

The keyword being "a lot of ideas that MAY come true in the future" Considering you're unsure if the technologies to colonize Mars will be brought to fruition or not, how can you say that full-scale colonization of Mars will be feasible in the future? You realize there are many technologies we have right now but can't get into large-scale operation because at larger scales, the power needed for them would violate the laws of physics? Teleportation, Star Trek-style tractor beams, reactionless drives (engines that do not require ANY fuel to operate, whether solar, hydro, fossil fuel etc which would be AMAZING for space travel), how to time travel (I'm serious - in theory, we can and a scientist recently proved this. Practically, not a chance), even crude fusion reactors are all there - there's an international project to build a fusion reactor ongoing in France right now. Should be complete between 2018-2022, and preliminary tests are already ongoing. They're just not economical to research because they're either impossible, or so unlikely to see a breakthrough, you'd be better off donating that money to charity or funding other, more relevant research instead. Edit: Don't forget the genetic engineering that would be needed to allow humans to live in Mars' lesser gravity without adverse effects like bone density loss and muscle loss and other health problems.

Progress in Space Technology as a whole and Knowledge of it and the theory? Yes. Progress in manned spaceflight? Nope we took a giant leap backwards when Nixon chose to fund the re-usable Space Shuttle over the permanent manned Lunar Base and possible mining operation NASA had proposed, or a Space Station in Lunar Orbit, and the Soviet Union collapsed and couldn't continue its own manned space program, what with Russia having an economic breakdown and the other former-Soviet countries being too fucked up to care about Space.

Nice. BTW did you know, Mars' core cooled so much long ago, that it became almost solid due to which its magnetosphere died out, allowing the solar winds to strip away Mars' atmosphere turning it into a barren hunk of rock? Did you know that to terraform Mars, we must first find a way to re-heat Mars' core to being liquid again, and then get it to spin, to form a new magnetosphere to prevent the new atmosphere from being lost again? After which, we will have to find a way to divert thousands of asteroids and comets from the Asteroid Belt (between Mars and Jupiter), the Kuiper Belt (beyond Neptune's orbit - Pluto is a part of this belt) and the Oort Cloud (on the very edge of the Solar System and extending beyond it) to crash onto its surface to provide it with the water to form lakes and oceans, and allow the frozen gases contained within those rocks to permeate the atmosphere and bring its density to something resembling the Earth's, and the dirt and dust thrown up by these impacts will trap heat in the atmosphere like a beneficial greenhouse effect, to warm it up to Earth standards? That massive outposts will have to be established across Mars, that will turn all the gases released from these asteroids and comets, via various different chemical reactions into an atmospheric mix resembling Earth's with 78% Nitrogen, 21% Oxygen, and 0.9% Argon? That this will take centuries if not millennia and the first colonists may well be the great-times-a-thousand-grandchildren of the people that decided; "Hey, you know what would be cool? Let's terraform Mars and spare no expense so we can live there! Wouldn't that be fantastic? So what if all that money could have been spent researching Faster-than-Light travel to colonize already habitable planets, or alleviating poverty and hunger on Earth? Making Mars Great Again sounds like an awesome idea!"

Look people Antarctica right now will be more inhabitable than Mars even after decades or centuries of terraforming. You can still breath, you don't need to create your own oxygen, and you are not dependent on a spacesuit to go outside. Forget large-scale Mars colonization being even remotely similar to life on Earth.

we are mankind we know how to warm a fucking planet up we pollute it like we do best OH WAIT MARS IS FULL OF CARBON DIOXIDE WELL ONCE ITS WARM, we plant trees which turn carbon dioxide into oxygen Mars was once like Earth plus how de we know lighspeed travel is even possible Mars is also rich of untoucned resources which is why we need to start there mars already has liquid water near its equator like i said can get over 32F, also what our core is like is not known since weve never seen, the deepest hole ever dug was the Kola Borehole in Russia it went 6.8 miles down and it couldn't go any further we never even got close to the mantle, mars has a tiny atmosphere so that's a start, we cant stay on Earth forever or we are doomed, and if lightspeed were possible and if you believe the universe is 14 Billion years old wouldn't you think a civilzation wouldve started very early and billions of years before us invent light travel and colonize the universe if this were the case, they wouldve found us probably before we came into existence, so why isnt there any others out there, which brings the question, if the universe is so old and has great ingredients to make starts AND planets orbiting around those stars which those planets have a chance to be rocky and and lower chance to be in the goldilock (habitable) zone, not too cold (like the outer planets(, and too close (like venus, which once had liquid water but it all dried up) then a lower chance to have water, which were not completely sure where we even got all our water in the first place, comets are know a unlikely possibility because the Rosseta mission to a comet found that to be able to bring the amount of water to Earth with comets youd need so many that its highly unlikely comets brought the water, now the great bombardment might be what brought the water, but most of the impacts hit our moon, not to mention the asteriod that wiped out the dinosaurs, which many animals did survive a prime example is ants, but that asteriod almost wiped out life, a asteriod made mars the way it is and yes it would take a long time to terraform and it would be expensive, but its possible, people think why go to mars when we can go to another solar system with planets that MIGHT be habitable but with our current technology itd take 36000 years to reach the nearest star aka Alpha Centuria, which might have a planet suitable for life, so wasting time for a lightspeed technology that is out of our capabilities to create shouldn't be our first priority, while we can do both at the same time exploring our solar system is a better option, also remember Voyager it was launched in the 70s and hasnt even yet left the solar system though its getting close

Let's analise this... USED TO HAVE? What does that have to do with its present? We're not gonna go back in time, we can't. Do you even know what being in the habitable zone means? If the Earth possesed thousands of active volcanos making its atmosphere totally unbreatheable, would it even matter if it is in the habitable zone? Fuck sake, people's capacity to think beyond from the sensationalistic headings has been incredibly shrunk... Learn to be critic and to reflect over things.

Having water doesn't mean something is habitable or that it ever really had any sort of life in it! Also, yeah, it is common knowledge that there is ICE, solid state water. What kind of creature do you think lives inside ice? Creatures need liquid state water! Has there been liquid water in the past? Evidences show it could have been possible. So? Even if there was, is there any water any more? Nope, only ice. Not habitable any more. Could it have been habitable in the past? WE HAVE NO CLUE. Why? We have no idea of how its atmosphere was, what temperature did they have, etc. Water is not a reason sine qua non for life.

Really? You know how to warm a whole planet up? Including the core of a planet? btw, to polute it you need a strong enough atmosphere that doesn't let gases scape into the universe (which mars doesn't have) and you need the raw material to create that pollution. Btw, don't even think about burning things, there's no oxygen to burn anything... Warmth does not come only from CO2.... " A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C)." Tree can't grow up with 0% of oxygen and needs certain minerals and soil to be able to grow. Also, to reach the amount of O2 we have nowadays, you'd need milenias. Mars does not have liquid water near equator, it's ice. If it were liquid water, it would sublime directly into vapour due to the minimal preassure their atmosphere applies. And even part of its ice is actually solid CO2, imagine the temperatures!! A tiny atmosphere is no start at all. Any planet big enough to have a significant gravity is good enough to retain gases, any gas at all, including those which can be poisonous to us. We're doomed anyway, even if we stay in Earth or not I don't think you really got into the specific details about having to terraform a whole planet... it would shock you to know how hard/impossible that is. It's not as small as you may think I'm starting to think you've watched too many Hollywood movies about colonising planets...

Learn to quote They confirmed the presence of solid state water and humidity in deeper layers of the planet, yet no superficial liquid water. Read it yourself if you please: https://www.theregister.co.uk/2016/08/24/no_we_havent_found_liquid_water_on_mars_says_nasa/,https://www.nasa.gov/feature/jpl/mars-gullies-likely-not-formed-by-liquid-water/. Maybe someday they find that liquid water but not yet. Please, keep in touch with new discoveries and I might just take you seriously (and inteligent) enough. For your information, liquid water directly EVAPORATES in Mars since the atmosphere does not apply enough preasure for water to stay liquid (learn basic phisics and chemistry). Show me all the technology you'd need in order to terraform it if you're so sure about it being possible... and then think of the cost and time "IF we live on mars...." It is a poisonous enviroment, deal with it already. Evolution has a limit. ONCE HAD WATER MEANS THAT IT ONCE HAD WATER. That's all. Water does not mean it is possible to live in it! Try putting any fish in distilled water and see how it dies! Any rebuttal to this affirmation? There are more things to life than just water.... ffs, try going on with your life without oxygen, without minerals, without organic matter and if you manage to survive, I'll freaking aplaud your intelligence. Habitable zone just means that it is far enough and not close enough to the star to be able to develop UNDER THE RIGHT CIRCUNSTANCES an appropiate temperature for water to be liquid. Mars obviously doesn't fulfil those circunstances. The most abundant elements are Hydrogen and Helium, get your facts right! Still, you haven't made a point with that. Btw, I'm a fking chemist, I know what water looks like, ty. Water does not flourish just like that! Wtf are you talking about? Spontaneous creation of water? Actually, Mars' core is a total mistery. We don't know if it even froze, which is an option Hydrogen binds with oxygen when both are monoatomic. Guess what? Hydrogen gas and oxygen gas are H2 and O2. They do not form water spontaneously. I don't even know what you're talking about. Ofc I have researched all this ffs, long ago and with people that actually understand this matters.... it's you who doesn't know the definition of habitable zone or how water is formed... Wikipedia: "In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure". Mars is inside the range of orbits yet it does not support liquid water since its atmosphere is too weak. In order to compensate, you'd need to bring nitrogen, oxygen and many other gases from another planet to Mars. MILLIONS OF LITRES OF GASES. How the fuck are you gonna achieve that without leaving the Earth without its own gases? And how do you plan to make Mars keep all those gases if it doesn't have the necesary gravity and magnetic field to do so? Answer this pls. Terraforming Mars, if possible, wouldn't only be too expensive to be viable (not sure who's gona pay for it, the mexicans?), it would take thousand of years. We do not have that time before the Earth gets screwed.

To be fair, we do know what happened to mars' atmosphere: it was all lost to space. https://www.nasa.gov/press-release/nasas-maven-reveals-most-of-mars-atmosphere-was-lost-to-space/ But I agree, I'm not sure wether the core froze or not, we just know its magnetic field got disabled long time ago by a fucking comet flying by... which is impossible to know if it would be ever possible to make it work as it used to work before. Until then, Mars' atmosphere is more than just screwed up. Not only does Mars lack the gravitatory strength it needs, it also lacks protection to mantain a proper atmosphere. In case Mars' core actually is frozen, there is no hope for that planet any more

It can be studied, same as we have with our own core. But not having any volcanic activity is not a good indicator since it usually means that a core will most likely be somewhat cool. As we already know, it is further from the sun than we are and its atmosphere does not retain heat, that's all evidence we need to know what happened to it actually. Matter tends to cool down after all.

But we really don't know, for all we know the Martians ruined there planet receded to the subterranean, and are using the core in some way to power there derelict civilization. Untill we get some equipment there I would avoid arguing what is fact and fiction. As a species we are very young an inexperienced still and our perception of reality will change as we evolve and gain knowledge. My favourite tin foil theory is we are from Mars and when the planet was dying our ancestors created humans from there own DNA and that of primates in order to create a sentient species that could evolve here on earth. Some of them came with us but died from the atmosphere creating religion in the form of our fallen ancestors. There is a hieroplyph in Egypt that talks about a king of men and gods alike that decended to earth from the heavens to govern his people, but grew terribly ill, and was force to return to the realm of God's in a chariot made of solid gold, that he created from the tributes he had taken from his people.

If there's something that will never change, those things are facts. Once we know a fact for sure, doesn't matter what happens next, it keeps being a fact just like atoms will never be proven to be false. Mars is what it is and if we ever wanna make it habitable, we'll need to build its atmosphere from scratch, fertilize the soil, tweak its temperature, build a magnetic field out of nowhere, stablish some sort of fresh liquid water resource, heat up Mars' core, etc. That's a titanic job, no matter the technologies we have due to what I've already explained beforehand...

If there were any sort of life remaining, we would have been able to detect it by now... there would be some trace, some heat signal, something that would inevitably point out to life. We already know how their planet degenerated tho: a comet passing by very closely screwed up their magnetic field. As for allien theories and such, I'm not sure what to tell you. You could think of us being created or catalized by some allien presence or you could just think that alliens happened to be here a couple thousand years ago. As far as I know, I can't prove neither of those but it sure would be interesting if that were true. But, where are those alliens now and why don't we have proofs of their visits? It kinda gets complicated, you'll have to wait some time before we might get any answer at all for this. PS: have you seen Prometheus and Allien (recently reliesed)?

I'm not a chemist, I won't pretend I am, but I will use the atom as an example of how I feel about facts. What exactly is a atom made of? What are those made of? I'm sure as our technology improves we will be able to see even further then the atom. Things are only facts because of the information provided so far. When new information is learned what is precieved as factual changes. A perfect example is dark matter and how it does not act like normal matter, we can't even obtain it to gain a scientific explaination. The day we are able to study dark matter is the day you chemist will have to relearn what is factual all over again. My entire point being that science is evolving and changing. That we are possibly one discovery away from rewriting history. I'm not saying your wrong, under our current knowledge your 100% correct. But don't stubbornly hold onto what is fact today when it might just be a tiny spec in human history. Everything could change and it would be best to embrace the future.

We can't even detect species at the bottom of our own oceans, you can't say that with 100% certaintly, no matter how likely. As for your other point maybe it is how they decided to treat us and let us evolve, a none interventionist policy, to allow us grow naturally they could of removed any trace of them being here. Or maybe they did leave traces and it's being suppressed or hidden by the powers that be. As for why they never came back, maybe they died.

See even further into the atom? In what sense? Phylosophically speaking? atoms are a fact, they exist, we've detected them, we've studied them, we've proved them. No further information is gonna change the fact that atoms exist. You talk of facts as if we were making guesses. Guess what? They are FACTS. Meaning they will not change because they are already proven. What you're talking is about theories that try to explain the behaviour of matter around us which are yet being studied. As for dark matter, we just discovered it somehow exists, you can't possibly compare it to atoms. The fact in dark matter is that there's something beyond our reach right now. And it's not gonna change. We might eventually understand it but it doesn't change the fact that it exists. Science is not changing. Science is developing, making progression or whatever you want to call it. But the basis stays relatively unchanged, no evolution there, only more deepness into knowledge, like a tree expanding. Heck... I wonder if you've ever read articles explaining facts. You sound like the perfectly ignorant student that doesn't want to bet for single answer when asked about a simple equation just in case he's wrong. I'm not sure you even realize what's our actual level of knowledge... There are so many misconceptions about science that I sometimes feel like keeping it all secret to citizens so they can't misjudge...

This is true... science will undergo a paradigm shift in the next 10 - 100 years, provided there's no nuclear event or similar world wide catastrophe that destroys the present base of scientific knowledge. Examining an atom's composition, is in part what lead to the realization that things aren't what they seem... 100 years ago, some relatively simple experiments showed that we don't know exactly what matter is... and not long after, quantum physics was developed, and it can mathematically predict the results of experiments better than any other model. The draw back being, that particles don't actually exist. But, in the absence of an explanation, we continue to use a material (Newtonian) model in most scientific applications because they are a reasonable approximation, and are consistent with what we perceive with our senses provided we don't look too closely at the data. Those who do look closely at the data, had all but given up. (If Einstein , Feynman and Bohr (and others) couldn't figure it out, who would?) This is what lead to quotes such as: "Reality is merely an illusion, albeit a very persistent one." - Albert Einstein (Note that Buddha also said something similar => "All is illusion".) With a model that can now explain the observations that the greatest quantum minds couldn't, it's only a matter of time ♥
