The heavens are getting crowded with billionaires.
Amazon founder Jeff Bezos is challenging Elon Musk and Richard Branson in a race to outer space.
Bezos detailed expanded plans on Tuesday for his rocket business, which will lug cargo, satellites and — someday — people into the great unknown. Like his fellow billionaires, Bezos has a far-out prophecy for where his Blue Origin project could lead.
"Our ultimate vision is millions of people living and working in space," Bezos said during a rare, 30-minute conversation with reporters after the announcement in Cape Canaveral, Fla.
Musk, the Los Angeles entrepreneur who founded SpaceX, envisions a "multi-planet species" that will escape Earth's suffocating pollution to live, for starters, on Mars — after nuking the red planet to warm it up, as he recently told "Late Show" host Stephen Colbert.
