Very soon. Russia taking people with enough money up into space is just the first start. I am sure that there are commercial ventures working with Russia right now to reinvent space travel. Once commercial interests get involved, you will see spacecraft getting up there faster, cheaper, and better. It's just a matter of time. I am very grateful to NASA for what they have done so far...but really, it's time to get a grip, and let other entities get in on the action.
Can you imagine....a huge prison system being set up on mars.....Wow...I bet that THAT would deter most criminals... [:)]
