If they want this mission to succeed the hardest thing is going to be separating out the nutters. I would imagine the biggest risk to the people on the spaceship once they've made it into space is each other. Being locked up with three other people and no way to ever, ever get away from them, it's all going to be about who can make that happen.

There's a good reason the first men on the moon were military. Stress tested and hardened. While I can see the british lad in this video is very intelligent I'd still rather have someone like Neil Armstrong at my back if the shit hit the fan.

I can see how this is all trying to raise awareness of the project but I'll be amazed if they send anyone who isn't tried and tested.

Yeah, the british guy seemed really intelligent, but really awkward (both socially and physically). I doubt he would be a good choice.

Obviously, I expect them to run extensive psychological exams on the last few candidates, I mean... these people will need to be intelligent, resourceful, with nerves (and balls) of steel, and also in good shape obviously.

^ Agreed. On the one hand, the candidates need a big-picture individualism, stoicism, and acceptance that they're leaving all the people they love behind -- they need the ability to "disconnect" from that human companionship-- yet they also have to somehow get along with 3 strangers. To say nothing of the ability to not totally flip out when a chestburster pops out of one of them during dinner.
