A couple of billionaires just blasted off to space. Here’s why you could be next.

When Richard Branson and Jeff Bezos blasted off on their own private spacecrafts this summer, it became clear that space travel was no longer solely the domain of government agencies. The question now is: How long will it be for those who aren’t super-wealthy to one day hitch rides beyond the Earth’s atmosphere? Josh Robin interviews Dr. Wendy Whitman Cobb of the U.S. Air Force School of Advanced Air and Space Studies. They talk about the cost of space travel, why leaving Earth on a rocket doesn’t neglect problems on our planet -- and the Jetsons. Plus, a debunked prediction about bacon of the future.
