Katy Perry set to roar into space on all-female flight
The "Firework" and "California Gurls" singer will be lofted more than 100 kilometers (60 miles) above the Earth's surface in a vessel from Blue Origin, the space company owned by the Amazon founder.
Five other women including Bezos' fiancee Lauren Sanchez will join the flight, slated to blast off from western Texas at around 8:30 am (1330 GMT).
Their fully automated craft will rise vertically before the crew capsule detaches mid-flight, later falling back to the ground slowed by parachutes and a retro rocket.
