It hurts to watch this
The whole premise of the show is completely ridiculous. A couple of simple facts: IF there's any water on Mars, it's a finite resource. There isn't anything that can produce water, more than it takes. No such thing as perpetuum mobile.
So, we can go there, make oxygen and live - for how long, with how many people. And then, that's that. Finished, over.
The end.
Edit: Even on Earth, predictions are that there will be WARS over water, as the resources dwindle (at an ever increasing rate). Not to mention how come that we're multiplying like rabbits, if four grandparents give two children, who then make one child.
What is the real question? Go to the Moon, Mars, mine for resources, discover an organism that can be the edge in biological warfare to rule the world? Why would they even want to do this, who is going to tell us - instead of selling us all of the propaganda, constantly.
It's getting a little old. Stale. I'm pretty sick of it, truth be told. :)
*Build a railgun, out of reach (of most), which can annihilate cities, countries; discover a new element to have impenetrable armor, a new weapon - you know, these are SOME of the real reasons they would be going and "exploring". Show it like it is, Cobra commander stop the propaganda.
