Aboard Blue Origin's New Shepard rocket will be Bezos, his brother Mark, and two other occupants – longtime women-in-space advocate Wally Funk, and Oliver Daemen, the winner of a $28 million charity auction for the capsule’s fourth seat. The 11-minute flight cost more than $2.5 million per minute.
The four will travel past the Kármán line, the 62-mile-high boundary between Earth's atmosphere and outer space in a flight that will last about 11 minutes. The July 20 launch date was chosen in honor of the 52nd anniversary of the Apollo 11 moon landing in 1969.
