Amazon CEO Jeff Bezos has laid out his vision for the future of our civilization, and space is at its core.

Speaking to the BBC on a show aired Tuesday night, Bezos called for a "dynamic, entrepreneurial explosion in space just as I've witnessed over the last 20 years on the internet – thousands of companies and tens of thousands of start-ups doing interesting things online."

One of the planet's richest people, Bezos, who founded Amazon in 1994, is also the founder of private spaceflight services company Blue Origin.

Appearing in the documentary "The 21st Century Race For Space", Bezos told physicist Brian Cox that one of the big problems with lowering the cost of a space launch today was that "we just don't get enough practice."

"The most used launch vehicles fly, in a good year, maybe 10 or 12 times a year, and you just never get truly great at anything you only do 10 or 12 times a year," he added. Tourism, Bezos told the BBC, could provide additional launches to "drive up the rate of practice."
