thats all.
also on topic, the scientist in me says we need to go to mars, just to say we have been there.

I believe that too.
In around 250 years the planet earth will be uninhabitable because of the pollution in our atmosphere. We must have a plane ready in case something unexpected goes wrong here.
If we perfect some kind of long distance travel, our best bet is to go to Gliese 581c
Who knows maybe we will be in space doing shit by 2050?

Stuff like this needs a balanced approach, we could have the most awesome spaceships ever, but it wouldn't mean much if they didn't have a healthy humanity to back them.
But, the amount of money and research going into earth studies, cant even be compared to how little is going into space exploration.
Think about this, if we didn't have an extreme case of global warming to compare yourself to (Venus) It's entirely possible our detection of it could have been delayed several decades past the point where we have a chance to do anything about it.
Space exploration also tends to spin off technologies that benefit a lot of people, without the Apollo and the shuttle program, we flat out wouldn't have any sort of computer processor even close to the capabilities that we have today.
The moon also has the potential to solve the world energy problems, for the next 1 million years. On top of that, it would be one of the most clean and efficient energy sources even known.
It would do this with fusion power. The main problem with fusion power today, is the two sources main sources of fusible materials (deuterium and tritium) are inefficient in their energy production.
The problem is the generation of high energy neutrons, these are extremely damaging to the reactor, create the most amount of residual radioactivity, as well as you cant really harness the energy they produce very efficiently.
The Deuterium + Deuterium reaction produces no neutrons, but it doesn't make much energy either, so it's tough to get a net-gain out of it.
The Deuterium + Tritium reaction creates lots of energy, but most of that energy is in the form of high energy neutrons.
The Tritium + Tritium reaction produces double the amount of high energy neutrons, tritium is also significantly more scares than deuterium.
The butter zone is Helium-3. It's an isotope of regular helium, and it produces significant amounts of energy, and no neutrons. The issue arises in the fact the only source of it we have is decaying neuclear weapons. So we have only produced around 155kg since 1955.
This is where the moon comes in.
The sun produces a significant helium-3 component in the solar wind. The earth doesn't benefit as the atmosphere deflects the particles. The moon on the other hand doesn't have an atmosphere. so its free to collect in the top 6 feet of the lunar soil.
So eventually we go through the top layer of the lunar soil. Collect the helium-3, and ship it back. This should give us plenty of time to devise the means of harvesting it from the gas giants instead, giving a much larger and more efficient source of helium-3.
So I could possibly extrapolate that space exploration could potentially go a long way towards solving the worlds climate problems...

Thanks for explaining it to me : )
Now I know a little bit more.
I've always been interested in astronomy and space exploration as a kid and even now, so this topic is really interesting to read and learn from.
But my interest in Psychology is a little bit stronger than in astronomy or space exploration, so I won't be learning anything big on my own.

Xrain, you should fly to the next launch at Vandenberg so we can chill. I live 15 minutes from the air force base.
//and supertoaster too but who cares

So only the humans are the only things going to live?
If we move to another planet -> No trees or other animals
If we just preserve Earth -> Everything is fine
Not to mention we probably will destroy that planet too
