.......and, at least for the foreseeable future, will probably continue to be so expensive as to be self-limiting regarding the number of passengers.
Well, there is a lot of money floating around out there in the private sector! And we may talk about the super-rich as the '0.1%', but 0.1% of 1 billion people is 10 million. I think the only self-limitation will be the challenge of building the rockets to satisfy demand. Selling tickets will not be a problem. And it will certainly become a major contributor to pollution and greenhouse emissions. But, as usual, we are going to drift into this and only start to question it when it is already well established.
And, by the way, all this talk of manned Mars missions exists only to keep the public enthusiastic (and to stroke the egos of certain entrepreneurs). Nobody is seriously working on any of that.
