Re: Fuel on Mars
getting people safely to and from Mars is about a lot more than motors and fuel.
True. But without motors and the fuel to, er, fuel them, you won't be going anywhere.
Leaving earth is our first step into space. And, assuming a) my faith is misplaced and b) something nasty this way comes, leaving earth is the only way for humanity to survive. Though looking at the elections recently in a couple of countries with "United" in their name, maybe humanity shouldn't survive....
