The Chinese have stated openly they want to send astronauts to the Moon and to Mars within twenty years. Well, that economy of theirs might pose a problem. But I hope they succeed.
Perhaps that is just what NASA needs. A goverment funded and mandated Space Race not unlike the Apollo program.
The Chinese are the guys to look at (or look out for depending on your political views) and if the US doesn't catch on they might just win this race if they can sort out some of their own problems.
A true visionary would figure out a way to make money from space travel, NOT dream up new taxes.
The Russians have figured this out. They've got a good idea with N'Sync's Lance Bass- I'd bet there are many people who would pay extra to leave him up there.
Why is sending garbage into space a good idea? The long-term ramifications of taking natural resources off the planet seem bad to me.
