Sonny, I Watched the Vault Bein' Built!
Our determination to kill one another eclipses our desire to explore.
Can we even generate propellant on the moon?
Mars in 1 months' time . . . Is that a conventional rocket or an ion engine?
Green houses -- Again, the problem of radiation wiping out the plants. The only way to shield from cosmic rays, that I understand, is to dig deep. Not too deep, but still a pain in the ass. Brick buildings underground might be able to deal with 99% of gamma waves, but . . . Isn't cosmic rays (Ah, I'll open my physics texts in a while and check . . . ) a different breed produced by solar flares?
"I think our determination to survive, explore and our desire to achieve the impossible will win out over complacency and procrastination." Or destroy us -- A common theme in Sci Fi.
Finally, the downside to microwaving is the creation of ozone in the atmosphere, specifically at ground level. *Shrugs*

The lunar surface or lunar dust (regolith) has a lot of Oxygen in it (http://en.wikipedia.org/wiki/File:Moon_Comp_Graph.png). It may not be feasible in small scale but in large scale (wth a lot of solar or nuclear power) it does not seem to far fetched.JayGrey said:

At its closest approach, Mars was 55,758,006km away from Earth. Even at that point a trip at 1g (lets call it 10m/s^2 for sake of simlicity) constant acceleration it would take...
It seems like basic physics calculation doesnT it?

I am not 100% sure but i think you don't need more than 5 meters of rock to resist a surface nuclear explosion (unless the whole thing collapses, let alone solar radiation. However building big galleries in a mine sysem to support agro domes is (without making the whole place a maze of lowest cost tunnel system) pretty unfeasible unless you have a goverment class sponsor financing the place.
However, building mine systems (not African deep mines mind you) to provide rew materials as well as digging in a planned fashion (for expansion into becoming habitat areas) may be feasible, if you can support an off word industrial complex for 50 or so years.
On another note, for a realistic space program Earth needs waystations in orbit. That way we can shuttle the fragile components like humans by the costly shuttleflights, while literally shooting raw materials into mid orbit (to be collected by tenders) by cannons. (Laser/Rail/Hydrogen whatever)
Can you imagine "any" world govenrment support a 50+ year program that will not give fruits for a 100 or more years?

Most of the other questions you asked were answered above. The ISS is being retrofitted with plasma rockets for testing in early 2012 late 2011. These rockets generate massive velocities.

EDIT:
This would be the most extreme type of community-minded societies, which is the complete interconnection of all minds and the rise of a new, collective consciousness would be the result.
Though Earth is not sentient, we might be on route for this type of ascendence:Technological Ascent
Exitmundi.nl is also a good, brief and fun source for seeing where we might be many years ahead.

This thread is comedy gold. Seriously.
Which it doesn't.
Oh and the Pope just rang and told me to tell you this:
"WE'RE NOT GOING TO COLONIZE SPACE. EVER. <strike>NOW STOP CALLING ME, YOU SICK FUCK.</strike>"
The idea that space flight doesn't cost us any fossil fuels is ridiculous to say the least. Unless they can make rockets with solar power nowadays and all the people in that industry ride bicycles. Unless the whole NASA infrastructure runs on water and air and so on.UncannyGarlic said:

Alec, be serious will you. We (mankind) managed to acquire the capability of space flight in the 50s. After that we just forgot about it as it does not bring any immediate profits and there is not any large dickbeating contest.
In reality the "space flight" portion of the whole mess is the least fuel needing and most simple part. The damn 800Lb gorilla is the escape from gravity well part (without killing the passengers).
The most reliable solution (that I have ever seen proposals of) is the waystation approach which is slow and steady. If JFK admin. had gone for that approach (instead of fast, brute force and overpriced Apollos) then we (man) probably would have colonies in solar system by now.
For the main info structure building and the passenger lifts out of the grav. well, we will be shackled to the fossil and derivative fuels for a long time. However beyond those we don't need the fossil fuels. We need the basic elements and radioactives themselves.
On a more funny note, we (mankind) use aluminium derivatives for our Rocket fuels as carbon based fuels (petroleum derivatives) are not efficient enough. However the rest of the industry are based on carbon based fuels, thus the dependency on petroleum (for now)

That's like asking a baboon to stop scratching his arse: it ain't gonna happen.cronicler said:
No, but seriously: all of this, all these pipedreams kids have, man, sometimes I wish I could still believe in them as well. It's just that reality hit me one day and it all became perfectly clear: we're stuck here. And we're on the brink of extinction. Someone should make a flick about that.
Seriously? I thought they used liquid hydrogen. How daft of me, no?

I know what you mean (about the dreams). Anyway It's not actually a dream. All you need is a corporation/country that has enough massive assets to channel nearly all of its profits into a sinkhole for about 20 to 50 years to achieve monopoly on Earth's orbit. (And yes as vague as this sounds this was intended as reality and sarcasm)
And no thats not daft of you. aluminum-oxides are self oxidising and produce a lot of energy so they are used as catalysts to ensure the whole thing does not die out and reaction consumes the fuel completely. Liquid (stance is just for storage purposes under heavy pressure) hydrogen and Oxygen is the main burners.
On a semi-related note; the space going rockets we use today are actually a lot cruder than the submarines we (humans) can build.
