How soon do you think space travel will be available to families...?

... that is, you and the kids get in the spacecar in the driveway, and you're looking down on half the Earth in 10 minutes.

I would say at least 2 or 3 centuries from now.

It'll be awhile because we still don't have flying cars yet, like you see in sci fi shows.

Well it only took about 50 years to get from the first manned spaceflight to commercial space flights...so who knows, probably not soon though, the main thing would be the huge costs (not to mention the technological advances we still have to make)

100 to 200 years from now. maybe sooner.

A long, long time. Maybe never. But I could imagine airline like space flight, where you go to the space port and board the spaceliner for a flight. It could be real within the lifetimes of young people alive today. But not me, I am too old and won't live to see it.
