Amazon founder enters space tourism race |

Amazon founder Jeff Bezos is getting ready to ride his own rocket into space. The 57-year-old billionaire says he'll go on the first passenger flight in a Blue Origin capsule in July. He's also taking his brother and is auctioning off a third seat to the highest bidder. Only a few hours after the announcement, bidding was already at over $3.2 million with thousands of participants from around the world.

The trip will last a total of ten minutes, four of which passengers will spend above the Karman line that marks the recognized boundary between Earth's atmosphere and space. After lift-off, the capsule separates from its booster, then spends four minutes at an altitude exceeding 60 miles (100 kilometers), during which time those on board experience weightlessness and can observe the curvature of Earth from space.
