Hey, I am willing to learn new stuff and new info is always good. But this does seem to me like they are underestimating the size of an entire planet. Think of the entire industry and transportation of earth and what it has really done to the climate here (very little). I mean, all the green house ...

... just a few parts per million of the super-greenhouse gases ... Let's examine that. The Mars Atmosphere is 25 teratonnes, according to Wikipedia, so 1 part per million would be 25 million tonnes. Let's say that you have 25 factories in production. If each factory produced roughly - 3 tonnes per ...

Yeah, sure. Hey all we need is a few factories spread all over mars and then we will cause a super green house effect. Mhmmm... It is all so simple! Why didnt I think of that? ...planetary scale... sigh... Are the ingredients for that gas even present in the marsian regolith? Well Chris McKay and t...

And PFC's are only 6,000X as potent as CO2. The earlier mentioned NF3 is 17,000 as potent. Furthermore if there already is a colony on Mars then most of the mass of the factories could be built on mars using martian materials, and only the high-tech "guts" made on earth and shipped to mars.

really not my idea forgive me for suggesting such : http://www.redcolony.com/art.php?id=0101050 From the posted link : Author Kim Stanley Robinson, has plans that could change the face of the Red Planet within a mere sixty years. He envisions a line of factories scatted across Mars such as those de...

with huge amounts of out-gassed CO2 and water vapor to make the surface temperature and pressure earth like with liquid water on the surface And how do you get those? I suggested bombardement with small asteroids, which is what a study on the topic suggested too. Better than nuclear explosions due ...

It would take hundreds of thousands(if not millions) of years for the solar wind to remove the outgassed atmosphere. I would say that depends on how dense it is... Also dont forget that the magnetic field also serves the purpose of protection from radiation. Either way, the second option that I pro...

[You understand the scales that we are talking about there, right? It is often amazing to me how people can underestimate planetary scales. Also, without a magnetic field, the solar wind will quickly "blow" away that little atmosphere that you are producing there. My concept was about giving mars' ...

That's not what I was getting at, but putting that aside for a moment - I don't see how you figure that Mars terraforming is anything but such a very long term prospect that colonization couldn't be worthwhile in the mean time. Please read back in the thread. My concept for terraforming would proba...

Or Mars. It's a toss up and frankly colonizing Mars is more inspiring. Unless it falls on its face for some reason (ie because it's too hard compared to e.g. the Moon). Well, the point of the conversation was that I suggested to terraform Mars first (as it is the planet in the vicinity where it see...

Keep thinking that way and you guarantee we get nothing done. This is the O'Neil nonsense that has left us with no progress in space the last 5 decades. So long as space advocates lie to themselves about how space can be made a viable economic option, we'll have these inane dreams supplanting real ...

This sounds like a good idea, but if you are thinking about having a breathable atmosphere under the dome, there is a problem. It has to do with the difference in pressure needed for humans to breath under the dome, and the existing pressure of the Mars atmosphere. On Mars, the "mean sea level" atm...

Well I do think something like TRITON could give us a cheap enough propulsion system for explorers to take us vicariously to other worlds in our system. That's why I made the recommends I did to the Augustine commission. However, that doesn't mean such a system could ever be economical enough to ta...

IIUC, fusion has a much lower power density than fission. Fusion rules when it comes to avoiding nasty by-products; not in what it takes to generate propulsion. Either way, fission and fusion rockets CANNOT give us cheap and easy access to this planetary system, and certainly not the stars. The sta...

On earth our shielding from radiation from space is both the earth's magnetic field and our thick atmosphere. After all my understanding is during pole shifts the earth's magnetic field fails for an unspecified period of time. The last one was about 700,000 yrs ago. If our atmosphere gave us no prot...
