1. Dude in beret is crazy as hell :)
2. Its actually 2008 and not 2016 documentary - and age starts to show...
3. Moral obligation? This sounds oddly like manifest destiny. Here we go again spreading plagues, committing genocide, and enslaving green men.... unless it's the other way around.
4. this is History Channel
5. None of the currently shown methods will ever take men to Mars.  Cramming a man into a volume the size of a closet for six months will result in one insane man.  Travelling in an unshielded ship will be like playing Russian roulette every day.  In the whole film it was never proposed that we use NUCLEAR power to get there.  Why travel in a Conestoga wagon when we could go in an ocean liner.  An Orion class Space Ship, massing 10,000 tons could carry a crew of fifty or more people, each with his/her stateroom.  The ship would be large enough to rotate around its axis to provide Earth normal gravity.  The ship's outer armor of several inches of solid steel would protect the crew from solar flares.  When could we build a 10,000 ton Orion?  We could have built it over fifty years ago, but refused.  Until we get the guts to build it, we aren't going anywhere in space.
6. National Geographic is becoming more like a nuisance to space exploration then it is useful info!
7. Terraform mars please....
8. NASA already had one astronaut trying to kill another astronaut.
9. It's time to stop the left everywhere, otherwise we won't get forward
10. As exciting as all this Mars stuff is a believe me I am excited, I fail to see how they are going to deal with the reduced gravity on Mars. It always seems to be that these documentaries just skip over it, obviously you can't spin a spaceship realistically on the surface.
    Only solution I can see is genetic modification and that's not a real solution to getting any of us living on Mars or even visiting for extended periods.
11. Some day we will have interplanetary travel but let's clean up this one first.
12. 27:31 I think it would be a good idea to also use a small RV at Devon Island because some EVAs may require to many kilometers away from the main base.  One problem with Devon Island is that daylight and night would be extreme during summer and winter respectively.  Maybe there is a high, cold desert nearer the equator they can use.
13. it would seem to me a much smarter idea to me to create Earth orbiting colonies in spinning toroidal form first supported by Moon mining for construction. The second era would be the construction of giant spinning cylinders 2 miles or more in diameter containing a full Earthlike environments.
    
    I don't believe we should colonizing Mars anymore than Antarctica for mostly the same reasons. Spinning orbiting colonies don't have the gravity issues that Mars has also.
14. A colony on Mars should be composed of a network of underground tunnels, preferably near the poles where there is plenty of water and meteor impacts are less likely. Also Mount Olympus with its geat height and low lattitude could provide an adequate foundation for an electromagnetic ramp to launch objects into orbit.
15. how about having two space ships built in one so the outer skin turn one way and the inner skin turns the other way and the ship can fly in a straight line if that makes sense to you
16. fix earth first
17. Just a wild theory, We, our species as humans were earth colonizers from Venus. Venus became wild as to condition,atmosphere due to green house gas effects. Then Our forefathers (w, mothers of course) did just the very same stage what NASA or earthlings have be doing, setting eye o Mars. ;p>
18. As long as we don't have an adequate source of energy that could get us to other planets and back in a reasonable amount of time any discussion about space colonization is pointless. If we have any thoughts of going out there nuclear fusion research should be the priority.
