[citation][nom]asjflask[/nom]LOL @ people who think we'll ever be able live on another planet. Quit watching sci-fi movies and get back into reality. Even if we could live on another planet (not to mention actually AFFORD to move there) it'd take billions of years to terraform the planet into a breathable atmosphere. So unless you want to wear an oxygen breather for the rest of your life you can forget that idea. Humanity will be long dead before another planet is terraformed to support life because our Sun will burn out in a few billion years. I forget the exact number of years but it's less than 10 billion and more than 1 billion. Regardless, it'd take over 10 billion to just terraform any other planet. Besides, the only place we could get oxygen would be from Earth or from plants we grow in a greenhouse. Good luck supplying 1+ million people with that (assuming you could even get that many people to move there or afford it).This was a complete waste of money. I like NASA and its technological advances it has brought us, but this was a complete waste of taxpayer money. Money we don't even have to spend mind you.[/citation]
Actually, terraforming could be done far faster in theory. Such a planet would obviously go through various levels of habitability in the process. Habitable domes could likely be used in the mean time. It would certainly take far far less than 10 billion years to terraform a planet, hell the Earth's environment has flipped between an ice age and 'normal' about every 100,000 yearsish for a while now and that's without the impact human intervention can have. Of course it wouldn't take a matter of days but significant changes could be made within just a few years, getting things stable and habitable would like take a few hundred to thousand years. Think about it this way, like I said nature has been flipping the Earth's environment into an ice age within timescales of about 100,000 years. If we blew up a few nukes around the Earth now (i.e. nuclear holocaust), we could cause an ice age within about a year.
Although all of this is besides the point, NASA's not talking about terraforming the moon, its talking about hoping to find water so that a moon base would be easier to build. Why would a moon base be worthwhile? Well ignoring all the scientific benefits and general ideals of man going forward and exploring, the moon is laced with Helium 3, which is comparatively rare on Earth. Helium-3 can be used as a superb fuel source for Fusion power - generally seen as the power source for the next generation and future. Mining the moon for helium 3 to power fusion reactors on Earth is not nearly as far fetched or 'sci-fi' an idea s you might think. Economically, the moon could as well be made of gold.
