NASA has set its sights on the moon's south pole, a region believed to hold enough recoverable ice water for use in synthesizing additional rocket fuel as well as for drinking water to sustain astronauts.

Bezos, intent on moving Blue Origin closer to commercialization, underscored his broader vision of enabling a future in which millions of people live and work in space. He mentioned two important issues: reducing launch costs and using resources already in space.

"One of the most important things we know about the moon today is that there's water there," Bezos said. "It's in the form of ice. It's in the permanently shadowed craters on the poles of the moon."

The world's richest man and Amazon.com Inc's chief executive waved an arm and a black drape behind him dropped to reveal the two-story-tall mockup of the unmanned lander dubbed Blue Moon during an hour-long presentation at Washington's convention center, just several blocks from the White House.

The lander will be able to deliver payloads to the lunar surface, deploy up to four smaller rovers and shoot out satellites to orbit the moon, Bezos told the audience, which included NASA officials and potential Blue Moon customers.
