Is there any politically expedient way that we can just get the elephant of the ISS off our collective backs?
Cut its budget until something breaks then say that it is too expensive to repair.

Well, not a good start for 4Frontiers in losing Robert, but hopefully they'll get their act together. If not, sounds like there are others eager to take their place.

It seems to me that some very smart MIT guys could do a lot with $30 million if they know how to design and build much of the required equipment themselves.
The big cost is a heavy lift vehicle and the necessary and constant resupply missions.
But just because they can doesn't mean they should. It's too much risk. You don't go to mars on the cheap.
No, no, the $30M is like the spark from rubbing sticks together. Now they have to build the bonfire.

If you can't get there or get there with enough resources along with people because you don’t have the transportation system to do it, then your idea is a dead issue.
^^^ This is obvious.
That space ship would have to be able to take off from Earth without having a throw away most of it ship or with it needing large fuel tanks so it could be able to fly to Mars in two week to two month travel time and land on Mars and then be able to come back to the Earth also.
^^^ This is an arbitrary requirement.
The two are very different.
You can ensure failure by prematurely reducing your solution space.
But why would you want to do that?

Mr Richard van der Riet Wooley was wrong only by a matter of degree. His same opinion of the 4Fronteir's goals is directly applicable today, that building a base on Mars presents difficulties of so fundamental a nature, that we are forced to dismiss the notion as essentially impracticable, in spite of the author's insistent appeal to put aside prejudice and to recollect the supposed impossibility of simply being able to launch a minimal rocket into orbit.
Do you really not see the irony of quoting van der Riet Wooley in support of your argument? The guy was wrong. He was one of the most respected scientists in the world, he had access to a whole community of genius, and he was wrong. Probably some engineer said to him "well, maybe if you build it out of Titanium but that stuff costs $10000 per gram, it'd cost you $100 billion dollars." Impossible, never, can't be done. What did he say when the headlines read "REDS ORBIT ARTIFICIAL MOON" and "SOVIET SATELLITE CIRCLES GLOBE EVERY 90 MINUTES"? "Well, hrumph, who could have possibly predicted that technology x, y and z would become available." Is that what you'll say?

And once we have advanced fabrication technology I think it would be quite easy for anarchism to form.
Some technologies, like personal fabrication, enable anarchy, but there seem to be plenty of others that further strengthen hierarchies. Economies of scale are difficult to compete with, and they benefit from hitech as well.
Pre-terraforming, I think the inherently fragile nature of habitats will require fairly tightly regulated communities. Individual rebellion or just lack of discipline could too easily be fatal to an entire community.

This is a completely arbitrary requirement. There are many things upon which the success of a Martian colony depends. This is not one of them.

I assume you are familiar with the term "vanishingly small" right?
I don't think these guys have any real chance at all. None. Zero. Their goal is patently impossible without a massive eleven-digit budget, and the chances that they could gather that kind of money with any kind of space-centric business model are non-exsistant.
Asteroid mining isn't going to be an income source, not for a long, long time anyway, which means every penny has got to come from some Earth-based product or service. There just isn't anything they've got to offer for that kind of money.
never, never, never, impossible, impossible, impossible, can't be done, etc

I'm strongly against "Intelligent Design" as a non scientifical theory.
Here you go, something to cheer you up ...

... lichens have the capacity to resist full exposure to the harsh space conditions, especially high levels of UV radiation. Analysis post flight showed a full rate of survival and an unchanged ability for photosynthesis.
That's really quite freaky that the lichen basically just shrugged off 14 days of hard vacuum.
Awesome links karov, thanks.

Let me rephrase that... nobody can do it starting with either zero infrastructure or essentially zero startup capital, and 4Frontiers has neither. $30M isn't nothing, but with the cost of labor/engineering, machining, and control hardware of modern space craft it just isn't possible to DO much but make big ideas.
And unless they are banking on some rich guy sending them a check with nine digits, just how are they going to rake in any real money? Their "business model" is non-exsistant when we're talking the sums of money to contemplate building a Mars base.
Right, the $30M isn't going to fund a Mars base, it isn't even going to fund the PR mock-up they want to build. The $30M just gets them into low financial orbit so that they can try for the next round of funding. The Mars base isn't going to happen until after IPO and before that I bet they try asteroid mining to get some serious revenue on the board. If they get lucky with some patents, they won't even need to do that.
They have a shot at this. There are a dozen ways for them to crash and burn, and most likely they'll be bought up by a bigger company before they launch their first ton, but, hey, if you don't play you can't win

A difference between the Martian frontier and, say, the American frontier, is the restricted options for someone who is dissatisfied in a community. Especially at first, there will be resources that cannot be created on Mars. One example is power. Power is not merely a luxury on Mars, it is essential to survival for any significant period of time. A single person or small group deciding to break-off from a larger group must acquire sufficient power generating resources.
But look at the power generation options for Mars: nuclear, solar, fuel cell. Local manufacture of nuclear generators and fuel just isn't going to happen anytime soon after settlement. Local solar or fuel cell manufacture is more likely, but each involves specialist equipment and/or materials (e.g., dopants, fuel cell membranes) that make it easy for a single group or even a single person to monopolize the ability to produce new power generation capacity.
I'm sure power isn't the only vital area where such monopolies could arise. The point being that it may be easy for a monopoly to disallow establishment of competitive settlements if there is no higher authority explicitly requiring that they be allowed. In this situation, the frontier could look a lot less entrepreneurial and a lot more centrally planned than I imagine you'd like.
I think true independence will require quite advanced personal fabrication technology.

Nano World: Power for soldiers, sat phones
Fuel cells generate electricity by reacting fuel with oxygen. NanoDynamics in Buffalo, N.Y., is developing fuel cells that employ nanotechnology to help supply power for longer times at less weight and size than batteries or conventional fuel cells. One 50-watt solid oxide fuel-cell prototype, roughly the size of a loaf of bread, is composed of roughly 20 percent nanomaterials and can generate some 3,000 watt-hours of electricity from just 5 pounds of propane. A conventional solid oxide fuel cell given that little propane would generate only one-half to one-third as many watt-hours.
The prototype, "originally designed for a combat soldier, could replace about 35 pounds of batteries," said Keith Blakely, chief executive officer at NanoDynamics.

200 000 tonnes of HF per annum at on average estimated 25 ppm abundancy???
Well Earth has 20 ppm abundancy and we produce enough for 2 million tonnes of HF. Is there any reason you know of that Mars won't have similar high grade fluorite ores?
Wouldn`t it be more energy efficient, elegant and at the end - CHEAP, if we produce the flourine in the mother natures way???
To be honest, I've never thought of nuclear transmutation as particularly energy efficient. But then again, I didn't know that you could build your own fusor for under $10000 8) I'll ask for one for Christmas and see how much fluorine I can make.

crazy, liar, blah, blah, blah
I don't get it. Everyone here thinks this can be done, that someone will do it, and that one day it will be profitable. The only arguments are over when, who and how much credit they'll need in the meantime. 4Frontiers is certainly bold to answer: now, us and whatever we can get. But when did having courage become crazy?

I'm not sure I'd work for someone paying half of what NASA offers for the same job.
Yes, a lot of talent will be lost which is tragic. I hope someone is putting together a plan to try and keep the top teams together - although usually the best people leave as soon as they see which way the wind is blowing.

'bout the atmospheric fluorine traces... Would it be viable to just "air-mine" these, toghether with the airmining that already will take place for other elements/gasses?
Formisano puts HF at 40-100 ppb. That's comparable to, say, xenon in the Earth's atmosphere.
Now on Earth, xenon is produced as a sideline to nitrogen production - you liquify air and use fractional distillation to separate out nitrogen, oxygen, krypton and xenon among others. Nitrogen production is quoted in terms of hundreds of thousands of tons per year, oxygen production is quoted in terms of thousands of tons per year, krypton and xenon are quoted in terms of tons per year.
Now cryogenics is fairly easy (low energy) on Mars, so liquifying air isn't going to be a big problem. This works in your favor, but I think your production would be hundreds of tons of HF per year rather than hundreds of thousands of tons. You're only out by a factor of 1000 though. Good tech has leaped bigger gaps. I bet you could get most of that with a properly designed filter/membrane (something like they use in reverse-osmosis desalination - nanotech will help out here) and some of the rest with ridiculous power levels.
However, if HF is in the atmosphere, there are probably some nice fluorspar ores about. It's almost certainly going to be more energy efficient to dig those up first. Atmosphere processing might be a good option for long term maintenance though.
I believe the MRO has instruments that will detect CaF2, so we might get some data on this soon

Why can't the AltSpacers' seem to do anything besides shoot their mouthes off and drop mockups from airplanes?
They're just being careful. The first launch has to go perfectly or those whose faded laurels were threatened will gleefully tear them apart.
When NASA is axed as part of the current administration's self-immolation, the AltSpacers will be able to hire NASA's best and brightest for 50 cents on the dollar, which should speed things right along

To flatten Mars to a depth of 100 KM it would produce a flat circle of D=1636 Km
Well, there are a couple of challenges with this one.
The first is that you would have to move 1.3 trillion cubic kilometers of rock. If you could move a million tons per second out of the area, it would take 250 billion years. Even if you could vaporize a trillion tons per second, it would still take 250 thousand years.
I think you would have to hit Mars with something like the Earth's moon to make the flat area - but that might knock Mars out of its current orbit. And if you could do that, you probably just want to add to Mars' mass to give it more gravity.
Maybe you could melt the surface with a giant laser, but I think you'd evaporate the atmosphere long before you got your 1600 km lake of molten rock.
Also, if you actually achieved the modification without disturbing the atmosphere, I don't think the atmospheric pressure distribution would be spherical anymore - so you still might not get 1 bar of pressure at the center of the flat area.
We might want to try something a little more modest
