MAKE THIS HAPPEN AT ALL COSTS! ;)

http://www.physorg.com/news/2010-10-professors-urge-one-way-martian-colonization.html


For the chance to watch the sun rise over Olympus Mons, or maybe take a stroll across the vast plains of the Vastitas Borealis, would you sign on for a one-way flight to Mars?

It's a question that gives pause to even Dirk Schulze-Makuch, a Washington State University associate professor, who, with colleague Paul Davies, a physicist and cosmologist from Arizona State University, argues for precisely such a one-way manned mission to Mars in an article published this month in the "Journal of Cosmology."

In the article, "To Boldly Go: A One-Way Human Mission to Mars," the authors write that while technically feasible, a manned mission to Mars and back is unlikely to lift off anytime soon – largely because it is a hugely expensive proposition, both in terms of financial resources and political will. And because the greatest portion of the expense is tied up in safely returning the crew and spacecraft to earth, they reason that a manned one-way mission would not only cut the costs by several fold, but also mark the beginning of long-term human colonization of the planet.

Also, making it two way wouldn't be terribly difficult; you'd just need a space elevator on both worlds. Plasma-ion engines can reach speeds fast enough to facilitate interplanetary travel taking less than 39 days.

I think there are some flaws in the logic of comparing a Mars landing to traversing the ocean. While both have substantial risk in the transit stage, the Americas at least had a hospitable climate and...yaknow food, water, and air.

mars has water ice, the materials to make air, and you could have a greenhouse to grow food. My hope is that we're on mars to stay by 2025. It's probably going to be more like 2125 if lunar exploration has taught us anything...

The cost of sending a crew to Mars will probably be ridiculous for a long, long time. Continuing to supply them until they are self-sufficient will probably be ridiculously expensive for a long, long time.

We don't know if humans can procreate on Mars; we don't know if we should, (the moral problem of procreating if we know that the relative gravity or radiation is going to cause birth defects, death, etc.)

How many are we going to send? How many are going to make it there, and how long are they going to live once there? If they can procreate without problem, (other than, ahem, those associated with low-gee horizontal shuffle,) how long until they are "self-sufficient?"
We would need to send doctors and nurses and dentists; physicists, chemists and biologists. We are going to need psychologists.

Terraforming Mars so that colonies are truly, entirely self-sufficient and sustainable in nature is science fiction and we should all admit it. The only other option is to create artificial enclosures, "dome-cities," something like that. We'll probably extinct ourselves before we get there.


The article mentions political will and money. There's the political problem, the fact that many nations would need to band together to get this thing going. Even if we knew peace and worked on this, I think a Mars colony would bankrupt the entire world within the first ten years.

The political will would quickly fade; people would still be starving and thirsting to death. We would still have rape and murder and drug addiction. We would still have disease. People would start to wonder if it is worth it to pay trillions upon trillions of dollars for a Mars colony, (which is always promised to be at the edge of self-sufficiency by the politicians!) while they're still dying of cholera in the 2000's. Unless the scientific research was immediately beneficial to the average people, they probably wouldn't care about it without constant reminders that it could help them in the future, (if it even could!)

As for a lifeboat...meh.

I'm not saying we don't need one; and my position is not that the Earth will become unlivable for our species in the future, that to survive we would need to be able to leave, (assuming we stay around to that point.)
I just don't think we're ever going to do it.


As for the volunteers, have at it people. Just don't send a message back to Earth asking me to bail you off the rock when you figure out that we can't hack it there.

If I'm going to live on Mars permanently, or at least long term:

-I want to start my own civilization with a bunch of Free Software-loving people.
-I want to start a small Socialist society with said people.
-I would work to ensure that we'd have the best vegan rations so that everyone could enjoy good food.
-Terraforming FTW.
-Statues to the great programmers and philosophers of the last 100 years.
-Implement as many ideas from The Venus Project as possible.
-Culture and Multimedia would be encouraged to be open and free to help social growth.

Then I can wash my hands of all of the Earthling's problems and be happy in this society-that-could-only-happen-through-planetary-colonization-place.

For those that still don't realise how easy it is for us to go to Mars, find the (readily available on the internet & my local tiny country town's community library) documentary called "The Mars Underground"
which realistically explores Robert Zubrin's, Mars Direct proposal, & NASA's modified Mars Semi-Direct modification.

We have had the technical expertise to go to Mars for well over 20 years.

There have been multiple threads on this topic (here in this forum) over the last 4->5 years.

The order of things could do with a little modifications. First a robot should be sent to set up a base with at least a green house and other essentials, and when things are set up, then the humans should be sent it.

Personally I'm a fan of doing something with the moon before branching out to Mars with a permanent colony. Getting to (and from) the moon is far easier and cheaper than Mars, which could make it a good testbed for long-term Martian colonization technology.

I don't see starting off with one-way missions to Mars being feasible. If a two-way trip is a political minefield then sending a group of people to die on another planet would be even more so. We have very little idea how well people would survive there from both a physical and a psychological perspective.

Starting off with small two-way trips, Apollo-style, seems like a better first step. Get people landing on Mars, looking around, and doing science. Then after we've had a chance to actually field-test Martian survival equipment and know that it works (i.e. we don't kill any astronauts) we can look about an actual colony mission.

Just like the Europeans didn't start colonizing the Americas before they explored a bit of it, I don't think it's wise to start colonizing Mars until we've had some proper human exploration on it.

The surface of the sea (& the depths as well, due to 80% of plastic sinking) is already full, of toxin loaded (plastics by their nature absorb all chemicals) plastics.

For anyone who cares in the slightest, there are superb quality documentaries available on the subject of what we have done to our oceans & seas:

Moon's not gonna receive the same treatment - it's not habitable.

I agree. If they're gonna be sending people up there, they should at least make some preparations. But with today's technology, it's not necessary for exploration to be done by humans. A solar-powered flying explorer could do the job much easily.

Mars isn't habitable in the strictest sense of the term either. Yes, Mars is more hospitable than the Moon, but I'd argue that that is more than mitigated by the Moon's relative ease-of-access.

In any case, Lunar colonies would at the very least help us design robust, air-tight, maintainable colony structures. You can try building a whole bunch of different colony layouts on the Moon, and see what works best. Then you can carry that information with you when designing Martian colonies.


I agree that human exploration is no longer strictly necessary, but robots can't really tell us much about the psychological impact of being that far from home is, nor what kinds of long-term health benefits/risks would come from prolonged exposure to the Martian environment. There's something to be said for a long-term, two-way mission of astronaut-guinnea-pigs who can find these things out.

A prolonged "colonization test" mission, where a group of astronauts establishes a semi-permanent base to test out the technologies and facilities that one-way missions would later use would be of enormous benefit. After their year or two on Mars they can come back on their return flight (possibly an inter-planetary shuttle that goes out with the new crew -- kind of like a Martian ISS), leaving their initial base on the surface for future missions to use and/or expand.

But it's not going to be as sustainable as Mars colony and more expensive to maintain if compared to a successful Mars colony.

Well, that is not feasible either for which this one-way mission is proposed. They can't send a load of stuff to Mars enough for a long-term mission, and have enough fuel for a return flight.

A one-way Martian colonization mission is a ludicrous idea right now. Before we can entertain the possibility of manned interplanetary travel, we will need some infrastructure. A "skyhook"/"space elevator" or great advances in rocket technology would be good. Setting up a semi-permanent base on the moon would be a very good idea. It could function similarly to the scientific bases in Antarctica, where personnel are sent for extended stays. Or we would need large space stations. To even think of carrying out complex off-planet missions without getting a lot more experience of living and working in space would be suicidal. Then we build space-ships in orbit: the ship we fly to Mars would be too large to actually land on/take off from a planet. It orbits Mars, and the astronauts use smaller craft to actually go to the surface.

Before anyone goes to Mars, we would need to send unmanned crafts carrying all sorts of supplies, building materials, fuel for return flights etc. Robotic rovers and fliers would also precede any manned missions, to explore and locate suitable landing sites, carry out experiments and test equipment, and build some domes or whatever for the first human explorers.

The first manned missions would not be one-way - the first astronauts to go to Mars would use fuel and/or craft already waiting for them in orbit round Mars to return to Earth. It would be necessary for astronauts to return so they could be hailed as heroes and all that, which would make it much more likely that public opinion continues to support these expensive projects.

After a lot of short-term, then long-term missions, to gain experience of living on Mars, build greenhouses, domes and other infrastructure and maybe terraforming - after all that, it might be possible to send permanent colonists. Unfortunately that won't be in my life-time - I doubt anyone using this site today will live to see permanent colonization of Mars. But it will be fantastic to see any of the stuff I've written about here. I really do hope I'll be able to go into space before I die. But I'm enough of a realist to accept that I won't be going to Mars.

I'd like to share a revelation I've had during my time here. It came to me when I tried to classify your species. I realized that you're not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with their surrounding environment, but you humans do not. You move to an area, and you multiply, and you multiply, until every natural resource is consumed. The only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet. You are a plague, and we… are the cure.

Not true. It's true that the light of a planet 1 billion lightyears away will be 1 billion years old when it reaches us, but if we were able to instantly teleport there, that wouldn't be the case.

Ok? My point was that you can't look at a planet 1 billion light years away, and judge the state of life there, because you are seeing an image of what it looked like 1 billion years ago. In many cases I suspect a planet's life forms can change a whole heck of a lot in a billion years. Just look at us, we went from giant reptiles (dinosaurs) to small mammals with construction capabilities and space flight in only 65 million, much less a billion.

I think there are some flaws in the logic of comparing a Mars landing to traversing the ocean. While both have substantial risk in the transit stage, the Americas at least had a hospitable climate and...yaknow food, water, and air.Lol +1

Let's go to a place that has no breathable atmosphere, where liquid water can't exist on the surface because of the low atmospheric pressure, and where it gets up to a balmy -5 degrees C in the summer. Let's go live there and work our tails off trying to come up with ways to breathe, eat, and drink before our supplies run out. That sounds like fun to me.

It's not really like Total Recall. :)

Mars isn't really a great target for an attempt at permanent human settlement IMO. It'd be difficult and achieve relatively little.

Until we find planets with an environment that's fairly similar to Earth and have the ability to bioengineer humans who are suited for that environment then long-term settlement of other planets ain't going to happen. In a lot of ways it'd be easier to build completely artificial habitats in space than it would be to try and live on a very foreign world. And even living long-term in space it might be very useful to modify our bodies to suit.

Either way, humans will be very much a sideshow in our civilisation's space exploration for a long time to come. In almost every situation it makes far more sense to send a machine than a live human, especially when you consider how much more capable our machines will be in the future.

Also, making it two way wouldn't be terribly difficult; you'd just need a space elevator on both worlds. Plasma-ion engines can reach speeds fast enough to facilitate interplanetary travel taking less than 39 days.

Yea but there is one snag. The planets have this tendency to move and mars can be on the other side of the sun to earth at times. It might take 39 days at the closet point but the window is quite small for it. And a elevator? Really? Who wants to be stuck in a elevator for over a month? :P

P.S. I've actually watched a couple of pieces of television about the Mars Analogue Research Stations before this. Ho-hum without addressing the problems I mentioned in my first post to the thread.

Mars Society Australia also apparently (http://en.wikipedia.org/wiki/Mars_Direct#cite_ref-1) argues for solar and chemical power, in contrast to nuclear. What happens to the rovers every time their solar panels are covered in dust? They have to sit tight and wait for another storm to blow the dust off. With people, we could manually maintain the panels; but chemical power, (or nuclear,) should obviously be the first and foremost supply for a colony.
The solar is of such little use that I posit the weight of the initial shipment completely negates planning for it in a primary-source role at the colony within the first five years. If solar efficiency, (and the efficiency of the equipment they will be powering,) improves dramatically within the next two years, (and the high efficiency equipment is brought into a consumer price range,) I will reconsider my position on Mars Direct.

The only part of the mission that'd be dangerous for the astronauts that the movie failed to mention is the effect of prolonged less-than-1G gravity on the Human body. We know from the ISS that even with exercise, people's muscles (and bones too, I think) deteriorate in space. Now, they do have gravity on Mars. But the crew would be spending a total of a year in transit and about a year on mars sandwiched between the two trips to and from.

I'm less concerned about nice scenery, and more concerned at what seems to be a very "dead" spirit of enterprise and progress -- both generally as well as on these forums.

As I mentioned some time ago in another space-related thread, the value of scientific endeavour cannot be measured in mere decades, but rather after centuries have passed.


I would probably use the the money to save the earth and its inhabitant.

Save Earth? We may be able to save or destroy ourselves, but saving or destroying Earth is very far from our power yet. The K-T extinction event -- a meteor strike two million times more powerful than the most explosive nuclear weapon ever tested, couldn't destroy Earth or life on it.

Having said that, one-way colonisation of Mars will probably be suicidal without much much more research and development.

Perhaps we should stop wasting money on wars, and direct some of that to scientific research instead. The cost of the Iraq War (US$1.9 trillion, according to the Congressional Budget Office) has been 100 times more expensive than the 2011 fiscal budget for NASA (US$19 billion).

There's a saying: "Necessity is the mother of invention." But that isn't necessarily true. All through history we have seen that warfare is the mother of invention. Except for that brief period in the 1960s when travel to the moon turned out to be one mother of a mother of invention.

We can't say precisely what the benefits of a Mars mission would be, because we are not fortune tellers. But I feel confident in saying that a Mars mission would pay for itself many many times over.

Of course, a bunch of people refuse to invest in anything unless they know what they're gonna get out of it. I vote that such people should shut up and go do something else. Those of us who are truly interested in the future of our species will push for the "impossible", as we have all through human history (remember Christophe Columbus?

As the documentaries previously mentioned state, it would take 100 years or so (probably quicker as they learn more) to create a more useful atmosphere on Mars (which has a lot of frozen water on it).

Another thing (that I don't think has been previously mentioned) is that in the looong term future as our Sun starts the process of dying, it will become (temporarily) stronger, which will make life on Earth impossible, but it will for some time make life on Mars far more ideal.

I know, we have a few other problems to manage before we start looking down the barrel of that one, but it is still a reality.

Personally, I find the colonisation of Mars, which would in reality be a stepping stone to other Moons in our Solar System, & beyond; to be incredibly stimulating & exciting.

I particularly love Zubrin's enthusiasm, the doco' gives me more hope for humanity & its collective future adventures.

I'm no expert, but I don't think creating a breathable atmosphere on Mars is a realistic prospect. Atmospheres don't exist in isolation. Our atmosphere here on Earth is a complex balance of interactions between the rocks, the oceans, living creatures, the magnetosphere, and probably a dozen other things. You can't just magic one into existence by pumping out the right gas. If you don't have the magentic field to retain it, or the right geology to keep it in balance, you're scuppered.

In short, terraforming is bunkum. We have no technology that even begins to approach what would be required to pull off engineering on that scale here on Earth, let alone on another planet.

It may be possible to create an atmosphere, but maintaining it is an entirely different matter. Mars' atmosphere is thin and constantly deteriorating because ionized particles in the upper atmosphere are constantly being blown off by solar winds. Without a magnetic field there is nothing to stop this from happening with whatever artificial atmosphere we might create.

There are really two possible ways of rectifying this fundamental issue with the Martian atmosphere:

1- Keep a steady stream of new atmospheric gases flowing to replace what is lost. This is the easiest solution technologically, but probably the most-expensive in terms of execution: you need to acquire the gases from somewhere, ship them to Mars, and then pump them into the upper atmosphere. Constantly. It's like keeping a boat from sinking by constantly tossing bucketfuls of water over the side. It works, but it's not very energy-efficient in the long-term.

2- Artificially induce a planet-wide magnetic field. On Earth we have our spinning iron core that produces our magnetic field. Mars does not appear to have any kind of a fluid mantle or core. We could try melting the mantle to reproduce the same effect we have on Earth; there is evidence that Mars once had Earth-like geology in that sense, so we'd be restarting it. Obviously no one has any real idea how to do that, but ultimately that's the "prettiest" solution.

Alternatively we could place an array of magnetic field generating stations either on the surface or in orbit that would create an entirely-artificial field. Powering these stations is a huge problem though; creating a magnetic field that strong on a planetary scale would require vast amounts of energy, which ultimately must come from somewhere.


Teraforming Mars is a great idea, and it looks good in sci-fi, but at our present state of technology we're simply not there with any kind of sustainable, long-term solution. Will we get there eventually? Yeah, probably. We may even be able to thin Venus' atmosphere to the point where it could be rendered habitable as well.

But for the time-being I think the prospect of long-term, enclosed domes is the more practical solution to the Martian-habitation problem. And I would hazard to guess that most respected experts in the field would agree with that.

@ve4cib: I suggest you take the discussion up with the experts. They may have a thing or two to say that disputes your views.

Hazarding guesses is not the way they work. Though they may start with an inspiration (a hazardous guess), they then have to work at proving/disproving it, & then move on from there.

They (the experts) have to do enormous amounts of mathematical calculations, usually on software that they have written (or have had written) to help them solve or at least further their understanding of these problems.

I'm not an expert on the subject, so it is a total waste of everyone's time for me to gather whatever info' I can from the web & argue with you. As the info' I'd gather is mostly superfluous rubbish, that would then be reinterpreted by me, & spat out into a non-scientific forum, by a non-scientific person.

I prefer to waste my time on the web in other ways that I find more enjoyable these days. :)

Of course, a bunch of people refuse to invest in anything unless they know what they're gonna get out of it. I vote that such people should shut up and go do something else. Those of us who are truly interested in the future of our species will push for the "impossible", as we have all through human history (remember Christophe Columbus? Hardly anyone could see the point of his mission. But in hindsight his was one of the greatest achievements in history.)

I believe Columbus fell into this category.All old time explorers killed robbed and exploited the people they encountered .

It may be possible to create an atmosphere, but maintaining it is an entirely different matter. Mars' atmosphere is thin and constantly deteriorating because ionized particles in the upper atmosphere are constantly being blown off by solar winds. Without a magnetic field there is nothing to stop this from happening with whatever artificial atmosphere we might create.

There are really two possible ways of rectifying this fundamental issue with the Martian atmosphere:

1- Keep a steady stream of new atmospheric gases flowing to replace what is lost. This is the easiest solution technologically, but probably the most-expensive in terms of execution: you need to acquire the gases from somewhere, ship them to Mars, and then pump them into the upper atmosphere. Constantly. It's like keeping a boat from sinking by constantly tossing bucketfuls of water over the side. It works, but it's not very energy-efficient in the long-term.

2- Artificially induce a planet-wide magnetic field. On Earth we have our spinning iron core that produces our magnetic field. Mars does not appear to have any kind of a fluid mantle or core. We could try melting the mantle to reproduce the same effect we have on Earth; there is evidence that Mars once had Earth-like geology in that sense, so we'd be restarting it. Obviously no one has any real idea how to do that, but ultimately that's the "prettiest" solution.

Alternatively we could place an array of magnetic field generating stations either on the surface or in orbit that would create an entirely-artificial field. Powering these stations is a huge problem though; creating a magnetic field that strong on a planetary scale would require vast amounts of energy, which ultimately must come from somewhere.


Teraforming Mars is a great idea, and it looks good in sci-fi, but at our present state of technology we're simply not there with any kind of sustainable, long-term solution. Will we get there eventually? Yeah, probably. We may even be able to thin Venus' atmosphere to the point where it could be rendered habitable as well.

But for the time-being I think the prospect of long-term, enclosed domes is the more practical solution to the Martian-habitation problem. And I would hazard to guess that most respected experts in the field would agree with that.

I remember reading (in Red Mars or perhaps Green Mars - SF novels about the colonizing the planet) that some people had the idea of getting an asteroid that consisted mostly of water ice, fitting it with thrusters, then putting it on a very near-collision with Mars. The icy asteroid would "bounce" off Mars's atmosphere, billions of tons of ice would melt or vaporize, thus delivering a huge amount of water vapour to the Martion "eco-system").

I don't know how realistic a prospect this might be (I read SF, not astro-physics or ecology) but it sounds pretty cool. There's so much water ice flying around the solar system, why go to the trouble and expense of taking it from Earth?

Of course, it'd all be pretty pointless while Mars's lack of a magnetic field allows the solar winds/cosmic rays frm stripping the planet of whatever atmosphere we introduce. Figuring out how to create and maintain a magnetic field or its equivalent is a major goal towards any kind of terraforming. Maybe we'd just have to accept the need to live in air-tight domes and greenhouses, and develop lighter and tougher pressure suits for those who'd need to go on forays outside. If we can't change Mars to suit us, we'd have to change ourselves to suit Mars.

One of the main ideas for "taraforming" Mars, is not really taraforming, but polluting the crap out of Mars (basically just continue doing what we are doing now). This would create a dense atmosphere, and allow people to walk around on its surface without a space suit. They would still need oxygen, but nothing else.

Exactly. Mars is a dead world precisely because it lost its atmosphere.

Raising the dead is somewhat tricky when you're dealing with one organism. Doing it for an entire planet isn't a realistic expectation. You'd need to have the ability to make fundamental changes to the planet's structure and composition. We may one day have engineering capabilities on that level, but it won't be for a very long time. Creating a planetary magnetic field and raising the average temperature of an entire planet would require phenomenal expense of energy. I just don't see how it could ever be attractive economically.

Forget terraforming. There's faster, cheaper and more efficient ways to get what we wanted done on Mars. A small cadre of humans overseeing a large machine workforce would be much more realistic, and would tick all the boxes.

@ve4cib: I suggest you take the discussion up with the experts. They may have a thing or two to say that disputes your views.

My views have nothing to do with the fact that maintaining a dense atmosphere on Mars without a magnetic field to protect it from solar winds and other sources of ionization is impossible without constantly refreshing the atmosphere with fresh gases. That is a simple fact, supported by the laws of physics and empirical observations performed by experts in the field.

In order for Mars to have a permanent, self-sustaining, dense atmosphere, a planetary magnetic field must be generated through some artificial mechanism.

Hopefully that wasn't directed at me, because I said previously that i'm not an expert. Things like terraforming are purely hypothetical ideas, and i'm pretty confident the majority of experts would agree that they're not practically achievable with any current or impending technology.

To get an idea of what the experts really think, look at what is actually happening in space exploration. A human hasn't left low Earth orbit in nearly 40 years. Space exploration is a job primarily for machines, any human involvement will be pretty minimal for the foreseeable future.

How can you have a decent discussion if you're that closed minded on it? There are experts who specialize in these things that say that it can be done, so that's the end of the story.

If that's the end of the story, then why even discuss it? A one sided discussion gets old pretty quickly. Even experts don't always think of everything and can grow from brainstorming.

I've often wondered how much more advanced our space programs would be if the Soviet Union hadn't collapsed. The Space Race saw HUGE advances in space technology simply because the race between the capitalists and the communists put huge social and political pressure (and therefore funding) behind the programs. When two nations are desperately competing with each other like that the amount of funding that gets tossed around is huge.

Once the Soviet Union collapsed the vast majority of the political impetus behind the American space program died with it. The Americans were the undisputed kings of space, so there was no point in spending millions of dollars to do anything quickly.

Obviously the collapse of the USSR wasn't the only cause of the cutbacks faced by NASA. The public lost interest after the first few moon missions; space became "routine" so the media didn't cover it, meaning people stopped caring.

Honestly, I'm glad countries like China, India, and the EU as a whole are eying space exploration seriously. If enough countries start having such lofty, stellar goals we may be able to rekindle some of the public-interest spark that existed through the 50s and 60s at the height of the Space Race. High public interest means politicians will start throwing more money around, in the hopes of winning votes.

Yes, I agree, it was due to Russia leading in the early days of the space technology in combination with the cold war that motivated the US to spend the bucks & focus on being the first to plant their flag on the Moon.

The reason we haven't sent a manned mission to Mars is that there's no strong scientific or commercial argument to do so. You could argue that the same was true of the moon, but in the 60's manned missions had a better scientific case, as they lacked the skill in robotics that we have now. These days we're quite capable of building a very competent geological rover and put it on Mars, which kind of chops the case for a manned mission off at the knees. The cost-benefit ratio for sending meatbags isn't good.

IMO, manned missions will only happen when there's a commercial driver for it, and there won't be one of those until we bring the price of getting off Earth waaaaay down. At the moment the only real contender for that looks like a space elevator, but the capital expenditure involved in building one of those means it's not likely to happen quickly even if they solve the technological hurdles. In the meantime, we need rockets an order of magnitude more efficient than we have now.

I don't know about that stuff. I'm a scientific technical ignoramus. Information that I have been exposed to says that because the atmosphere is currently so thin on Mars, it makes it a vastly cheaper place, energy wise for us to launch whatever to further our space exploration.

Strange as it may seem; it costs more in fuel to fly to & land on the Moon (because it has NO atmosphere) than it does to fly to & land on Mars (because it does have some atmosphere).

The energy used in breaking the fall of the landing craft is apparently the reason. An atmosphere, even a thin one like that on Mars, is apparently an incredible energy saver when it comes to landing.

It is all so very interesting. I wish I was a wiz kid, I think I would happily dedicate my life's work to this Mars stuff.

I would find it to be such stimulating, educational good fun. :)

I think it's funny that space technology actually seems to be devolving in some respects. As an outside observer, it seems like NASA is doing less impressive things as time goes on. The new NASA Ares rocket can't hold a candle to the Saturn V. :(

Saturn IV was a freak project. Unfortunately, if you don't keep up projects like that, you lose the intellectual investment. People with the knowledge and skill die/retire due to old age, etc.

As I think was mentioned much earlier in this thread; it is apparently far more expensive to land on the Moon than it is to land on Mars.

Unlike the Moon, Mars does have atmosphere, which saves an enormous amount of fuel when it comes to landing there.

Some people who are experts, say that it IS possible, they already know how to do it, & they say that the time frame (which I previously mentioned) would most likely come down as they continually learn & optimise the technology.

Mars' gravity is only 38% of Earth's, so the fuel savings would actually be more than your estimate. :)

Terraforming seems a little too ambitious though. We could certainly build a base there, if there was enough political will to do so, and we certainly could send people to colonise it. But it would be a pretty artificial and lonely life on the Red Planet. Bleak scenery, green-house produced food, intense bombardment from solar radiation, extreme temperature variations, would have heavy physiological and psychological effects as well. You'd have to spend most of your day in bunkers or tunnels.

We are not all the same. There exist people that would thrive in the circumstances that the initial human inhabitants of Mars would experience.

In parts of Oz we have places so hot in the day time that people mostly live under ground. Not only is it extremely comfortable all year round (same temperature inside your house); in some places (Coober Pedy) they not only pay for the building of their house they make quite a profit out of the opal that they find in the excavated earth. :)

In other parts of the planet, people live in freezing cold conditions, (the Inuit for example) & they have been adapted to these extreme conditions for a very long time.

Man is nothing if not adaptable.

I'm surprised that there is so much negativity in this thread regarding the idea of humanity settling on & colonising Mars.

I would think that in the end it would be a very worthwhile experience. Who knows what new discoveries would be made in the years following?

Perhaps in the ice/water/rock they will find signs of life of some kind having previously existed on Mars?



...Please give some concrete arguments about why ionization by the solar wind is irrelevant.

I don't know. Go to the Mars Society website & have a read? Or watch the Zubrin documentary. He probably covers it there.

Seeing as NASA agreed (years ago) that the project was not only possible but doable (though they modified Zubrin's Mars Direct, to Mars Semi-Direct to make it easier on the astronauts) then I expect that they have long had the problem sorted.

Man is adaptable: true.

But people like the Inuits have adapted over many many generations, and even evolved to a degree to cope with their environment. Furthermore, they live in fairly organised communities.

The initial colonists to Mars will not be living in any kind of "community" as they are familiar with. Perhaps a small handful of people... stuck in the same steel pressure vessel buried underground for many months, perhaps years, with little prospect of meeting their families on Earth ever again, or interacting with a wider population face-to-face.

It will be very trying circumstances. No doubt that there will be people who will be able to cope with that, but finding such people will be a herculean task and not something to be underestimated. Even a small psychological breakdown by one member can destroy a small crew, even if the others are fine.

You're confusing "negativity" with realism. There are very real challenges that need to be overcome to make colonisation of Mars a viable project -- that is not to say we are not technically capable of it, but technical capability doesn't necessarily equate to success.

handy
October 30th, 2010, 12:36 PM
That's your take on it samjh.

I expect that there would be an enormous amount of psychological study beforehand, as well as training, & vetting, which would evaluate as intelligently & accurately as possible who is suitable. Just as is done for astronauts already, though tailored for the more complex Mars mission.

As I've said before, (one way or another) some very intelligent people who are highly skilled in a great variety of areas & also capable & willing to learn a whole lot more, & synthesise their knowledge to create the best future outcome, would thrive on meeting the challenges of life on Mars.

I think that there are many people who are bored stiff with living under what our society has thus far deemed to be the apparently immutable paradigm of consume at any cost.

Those that went to Mars would know from the start that they are never coming back to Earth.

A one way trip to with the intention of bringing a dead planet back to life. Quite the opposite of what we are doing here & now.

Er, not really. One thing we've learned from long duration space flight is that reduced gravity is a problem.

The environment on Mars is hostile to 100% of all humans. It's lethally cold, there's no breathable air and harsh radiation. Maintaining even a small short-duration party on the planet would be a major challenge medically and practically. We're still learning how to keep astronauts healthy in low Earth orbit, which is only a short ride down in a lifeboat to safety. Doing so on Mars would involve a much higher degree of risk. The margin of safety becomes a lot smaller. We'd need to do a lot of baby steps before making the big leap.

Which again is why it's so unattractive to send humans. We can build machines today that can go straight to Mars and be useful right away with acceptable risk. A manned programme would involve huge investments in time and money, it'd be risky, and i'm not convinced the science would be any better. We can explore much faster, better and more safely using machines than we can with humans. Given how much smarter machines are going to get in the future i'd say that's only going to get moreso. The only people I could see possibly mounting a manned mission to the red planet are the Chinese, who would conceivably be prepared to throw the money at it purely as a flag-waving exercise. Every one else will be too busy doing real science to bother.

If you read the link, you will see that a top advising agency to the pentagon is at the heart of this one:

Suzanne Goldenberg, US environment correspondent
guardian.co.uk, Saturday 13 February 2010

The brains trust of the Pentagon says it is just months away from producing a jet fuel from algae for the same cost as its fossil-fuel equivalent.

The claim, which comes from the Defense Advanced Research Projects Agency (Darpa) that helped to develop the internet and satellite navigation systems, has taken industry insiders by surprise. A cheap, low-carbon fuel would not only help the US military, the nation's single largest consumer of energy, to wean itself off its oil addiction, but would also hold the promise of low-carbon driving and flying for all.

Darpa's research projects have already extracted oil from algal ponds at a cost of $2 per gallon. It is now on track to begin large-scale refining of that oil into jet fuel, at a cost of less than $3 a gallon, according to Barbara McQuiston, special assistant for energy at Darpa. That could turn a promising technology into a *market-ready one. Researchers have cracked the problem of turning pond scum and seaweed into fuel, but finding a cost-effective method of mass production could be a game-changer. "Everyone is well aware that a lot of things were started in the military," McQuiston said.

The work is part of a broader Pentagon effort to reduce the military's thirst for oil, which runs at between 60 and 75 million barrels of oil a year. Much of that is used to keep the US Air Force in flight. Commercial airlines – such as Continental and Virgin Atlantic – have also been looking at the viability of an algae-based jet fuel, as has the Chinese government.

"Darpa has achieved the base goal to date," she said. "Oil from algae is projected at $2 per gallon, headed towards $1 per gallon."

McQuiston said a larger-scale refining operation, producing 50 million gallons a year, would come on line in 2011 and she was hopeful the costs would drop still further – ensuring that the algae-based fuel would be competitive with fossil fuels. She said the projects, run by private firms SAIC and General Atomics, expected to yield 1,000 gallons of oil per acre from the algal farm.

McQuiston's projections took several industry insiders by surprise. "It's a little farther out in time," said Mary Rosenthal, director of the Algal Biomass Association. "I am not saying it is going to happen in the next three months, but it could happen in the next two years."

But the possibilities have set off a scramble to discover the cheapest way of mass-producing an algae-based fuel. Even Exxon – which once notoriously dismissed biofuels as moonshine – invested $600m in research last July.

Unlike corn-based ethanol, algal farms do not threaten food supplies. Some strains are being grown on household waste and in brackish water. Algae draw carbon dioxide from the atmosphere when growing; when the derived fuel is burned, the same CO2 is released, making the fuel theoretically zero-carbon, although processing and transporting the fuel requires some energy.

The industry received a further boost earlier this month, when the Environmental Protection Agency declared that algae-based diesel reduced greenhouse gas emissions by more than 50% compared with conventional diesel. The Obama administration had earlier awarded $80m in research grants to a new generation of algae and biomass fuels.

For Darpa, the support for algae is part of a broader mission for the US military to obtain half of its fuel from renewable energy sources by 2016. That time line meant that the Pentagon needed to develop technologies to make its hardware "fuel agnostic", capable that is of running on any energy source including methane and propane.

The US Air Force wants its entire fleet of jet fighters and transport aircraft to test-fly a 50-50 blend of petroleum-based fuel and other sources – including algae – by next year.

The switch is partly driven by cost, but military commanders in Afghanistan and Iraq are also anxious to create a lighter, more fuel-efficient force that is less dependent on supply convoys, which are vulnerable to attack from insurgents. Give the military the capability of creating jet fuel in the field, and you would eliminate that danger, McQuiston said. "In Afghanistan, if you could be able to create jet fuel from indigenous sources and rely on that, you'd not only be able to source energy for the military, but you'd also be able to leave an infrastructure that would be more sustainable."

McQuiston said the agency was also looking at how to make dramatic improvements in the photo-voltaic cells that collect solar energy. She said making PV 50% more efficient would create a future when even the smallest devices, such as mobile phones, would be *powered by their own solar cells.
