So a small number of people can stay for short periods of time living off of supplies fed from Earth while they advance said chamber.
And that's after they've actually built the chamber which will take....several...several years at absolute minimum.
And then thas only astronauts and engineers.
And then that's still only very temporary solutions.
To turn that into a permanant livin' situation that can sustain more than a score of astronauts would take longer than any of our families will be alive and cost more money than we have.
And that's assumin' that all goes to plan and we land in 2020...which isn't likely.
actully plants help us breatheQuote:

Becasue they create oxygen and help sustain an atmosphere.
If we don't have this atmosphere we get swept up into space and eradicated by solar radiation.
We need plants to breathe, but we need a lot more than plants to remain alive.
Ever notcied that Mars was never famed for bein' the planet that has a lot of plants?
S'becasue there's none. We can't put plants there becasue there's no atmosphere. We can't make an atmosphere because there's no ecosystem. We can't make an ecosystem becasue plants die due to lack of an atmosphere.
Vicious circle, get it?
Therefore, we need to create artificial atmospheres.
Unless you have a way of growin' plants on Mars w/o all of that junk...millionaire overnight if you do, btw.
This post was only on the second thread and yes an old comment but oh gosh I laughed so hard at that!Quote:

The first is about the size of Mars and it's mass.
Mars is quite a bit smaller than the Earth and has much less mass.
Why is this a problem?
With the smaller mass comes reduced gravity, reduced gravity means that the gasses required to make an atmosphere would escape. :(
An atmosphere does more than give us the oxygen we breathe.
It helps to control the temperature of the planet surface and protects us from solar radiation. It is also a place where a large percentage of our fresh water is stored and is a vital part of the water cycle.
Without an atmosphere, any surface water would vaporise and be lost as gas. :(
Radiation from the sun would be a constant problem. Even here on earth we are finding out the damage that it can do (skin cancers etc.), even with our protective blanket.
Mars is a lot further from the sun than the Earth.
It would be very cold in the shade, or at night. But without an atmosphere, direct sunlight would be very hot.
We are an animal that likes to keep our bodies at a fairly even temperature.
So making Mars a planet we could live on. Is it possible? Yes it is I guess, but would be incredibly expensive.
Is it sustainable? No, because it would require constant maintenance and intervention by us on a scale that would be impossible to sustain.
We could live in domes and create small colonies. They might even be able to supply most of their own needs. There again, most of the biosphere projects attempted so far have been poor failures.
Let's face it, most of us are stuck right here and always will be. I guess we better try and make the best of it.
You know what's happening next year? The World Cup. Stop worrying about what's happening in 2012 when you should be worrying about how you're gonna not get destroyed in The World Cup. Aaaahhhh The World Cup.
I'm really just hoping that the creator of this thread is pretending to be like this to get some cheap laughs out of how we can't stand idiocy or something. Mostly because every time I read one of rikorikojie's posts, I just tighten the noose around my neck and cry a little at the plight of humanity.
