Quote from: Lary on 2012 Sep 20, 07:27:30The only problem with Mars is that the atmosphere isn't thick enough to hold the oxygen and carbon dioxide we, and in turn plants, need to live. The soil is proper, water can exist, and temperatures aren't half bad (will be even better when a stable atmosphere can be inserted).
Quote from: Book Smarts on 2012 Sep 21, 11:06:59We need to find some kind of water source on Mars , we can't export water from earth, it would strain our fresh supply, that's my only problem with colonizing mars
Quote from: Zygrograxgra on 2012 Sep 21, 18:05:03I say we should focus less on spreading our species across the galaxy and just keep a few planets at most unless we REALLY need to.
Quote from: Zygrograxgra on 2012 Sep 21, 18:05:03...make a machine that combines H2 and O?Use that for a bit, put the water out there, and you likely won't need to do it again. Repeat for each planet you'll colonize.I say we should focus less on spreading our species across the galaxy and just keep a few planets at most unless we REALLY need to.We won't be going to other systems with FTL or anything close to it, that I can guarantee. You'll likely disintegrate the ship, and if it collides with ANYTHING you'll have a sizable explosion.Where I learned this: http://what-if.xkcd.com/1/Yes, the content in that link is perfectly fine, I double checked.Ironically, it would probably be safer to mess with spacetime than to do FTL.Now here comes other intelligent life. It will likely be at or past the point we are in technology by then, and thus going to war with them would be a bad idea. They too would likely understand that, and would likely either ignore us or try to form an alliance of some sort, or at least stay neutral and trade.I'll post more later when it comes to me.

Quote from: Flinckie on 2012 Oct 02, 15:02:57There are some technological advancements we must make before this becomes feasible, but this topic interests me a lot.The first thing we need to take care of is transportation, since we can't colonize anything that's 8-9 months away. We need more efficient and less expensive rocket fuel. The solution has been staring us in the face for decades, but nobody wants to do it because it has a bad reputation. Of course I'm talking about nuclear propulsion. It's been estimated that we can cut the traveling time to Mars all the way down to just a few weeks, which is a lot more practical. Before someone makes this happen, we're probably not even going to manage to construct a base on the Moon. That's an important thing to note, too. We could use a lunar base as a docking station, so we could launch big spacecraft from there, where there's less gravity and no atmosphere to escape from. Imagine that, we could construct a big space rocket on Earth, launch it, and then it would never enter the atmosphere of Earth again.Another thing that needs to be addressed is that a base on Mars would be a lot like a research station on Antarctica. That is, more or less completely dependent on Earth for supplies. But it would be a lot more isolated due to the restrictions of the speed of light. The lowest possible distance between the Earth and Mars is roughly 4 light-minutes, and 20 light-minutes at most. This means that if you wanted to access an Earth-based website on the Internet, you would need to wait until the signal travels to Earth and back, which would mean a wait from 8 - 40 minutes, depending on where the Earth is. Not to mention that there would be no Internet access at all while the Earth is behind the Sun unless there's a relay somewhere, which would mean an even longer wait than 40 minutes. Same goes for all communications. Text-chats with your family would have this kind of lag.Let's not forget the health-hazards of prolonged exposure to low-gravity. The human body will lose muscle and bone tissue. The only real way to prevent this is exercise, exercise and exercise. You would also have to watch your blood pressure constantly, since it would go up. The health problems would apply to plants, too. Growing plants, even in light houses would take many adjustments. For example, the sunlight is not nearly as intense on Mars as it is on Earth, so you would have to keep artificial light going constantly, which takes a lot of energy. Another possible solution is specially-bred or even biologically engineered plants for low-gravity and low-solar exposure.The possibility of large-scale terraforming is not really available, since it would take tens of thousands of years.It would be very wise to make a base on the Moon before Mars, if only to gather experience on off-world settlements.Feel free to correct me if I'm wrong on anything, since my knowledge on this is mostly self-taught.
