Not only that, but what the hell is Leon doing to show that a sustainable colony can happen on Mars? Does he have a Mars colony mock-up here on Earth or on the moon with people working out everything that will be needed? Because there's a huge fucking leap from putting people and satellites in orbit to a space station and then to an actual colony in space. And everything I'm hearing from him is that a colony on Mars will need 100% replenishment from Earth, which is A) really fucking expensive and B) really fucking dangerous for the people eon Mars.
I'd be more impressed if Leon had taken some SpaceX ships and built a Skylab-esque space spation in orbit and kept it going and worked out all of the systems required (recycling water, growing food, etc.), or even landed something on the moon resembling a colonial outpost. Not to mention power plants - solar is great, and will be more efficient in space, but me thinks they may have to have at least a small nuke power plant.
And he still hasn't addressed how people are going to give birth on Mars, and what's going to happen to people on Mars who A) don't have protection on the surface B) have muscle mass problems.
