The trip is 60 years overdue for Funk, who was one of the Mercury 13—the first women trained to fly to space from 1960-1961, but excluded because of their gender.
On July 20, she will become the oldest person ever to go to space when she takes part in the journey aboard the New Shepard launch vehicle along with Bezos, his brother Mark and one other traveler who paid $28 million at auction for the seat.
"I can hardly wait," Funk says in a video posted on Bezos's Instagram account.
The video shows Bezos describing the trip to Funk, and then asking her what would be the first thing she said after landing.
"I would say, 'Honey, that was the best thing that ever happened to me!'" replies an exuberant Funk, throwing her arms around the laughing tech mogul.
Funk recalled her time in the Mercury 13 program—an unofficial, privately funded program which put women through the same training and tests as the male astronauts undergoing the official NASA program.
"They told me that I had done better and completed the work faster than any of the guys," Funk says in the video.
"So I got ahold of NASA, four times. I said I want to become an astronaut, but nobody would take me. I didn't think that I would ever get to go up."
She said people told her "Wally, you're a girl, you can't do that."
"I said guess what, doesn't matter what you are, you can still do it if you want to do it."
Four minutes in space
The Bezos brothers and Funk, who was also the National Transportation Safety Board's first female air safety inspector and a Goodwill ambassador, will be joined by the unnamed winner of the online auction who paid for a seat.
Taking off from a desert in western Texas, the New Shepard trip
will last 10 minutes, four of which passengers will spend above the Karman line that marks the recognized boundary between Earth's atmosphere and space.
The passengers will then be able to float weightlessly for a few minutes and observe the curvature of the Earth.
Then the capsule will begin a free fall back to Earth, braked by three large parachutes
and retrorockets before landing back in Texas.
New Shepard has successfully carried out more than a dozen uncrewed test runs from its facility in Texas' Guadalupe Mountains.
The reusable suborbital rocket system was named after Alan Shepard, the first American in space 60 years ago.
The automated capsules with no pilot have six seats with horizontal backrests placed next to large portholes, in a futuristic cabin with swish lighting.
Blue Origin's maiden crewed flight comes amid fierce competition in the field of private space exploration—with Elon Musk's SpaceX
, and Virgin Galactic, founded by British billionaire Richard Branson
, all jostling for pole position.
