I think it will take a complete international effort to get past the moon as the costs are so prohibitive, would be a great show of global unity as well. Sadly, I doubt I will ever see it happen even being at the moderately young age of 34.
Great idea of course.
The ISS was not supposed to be a way station to nowhere, so "astronauts" could do experiments no cares about. It was supposed to get us to the Moon ***dammit. But the space race ended, and so did interest in space. So things got half-assed. The world really isn't interested in space, frigging foreigners don't watch or know of Star Trek, Star Wars, Alien, 2001, warp drive, phasers, etc. They're deadbeats on the topic. China has got to land a dude on the Moon soon.
Some think, like the science guy on CBC tonight, who used the general idea that because bombers from WW2 were converted into civil planes the airline industry came into being. What the govt starts, business takes over. Except extraterrestrial businesses are a tad more complicated than Earthbound ones. It costs about $20,000 bucks to put one pound of anything in space and I've heard of no viable business plans to make money off space. Space tourism was supposed to happen a decade ago.
ISS- irrelevant space station
I don't think the ISS was ever intended to be a staging point for travel to the moon, it's primarily a research station.
