It’s the first time humans will go to space aboard the autonomous Blue Origin vehicle

The team of four people traveling in Blue Origin’s rocket ship New Shepard will include the youngest and the oldest people to ever fly to space, according to the company.

At 82 years old, Wally Funk — who trained for NASA’s Mercury program but was denied the opportunity to go to space — will become the oldest person to travel to space if today’s flight goes off as planned.

Funk volunteered as a member of the Mercury 13 program, otherwise known as the “Women in Space Program,” in February 1961, which was a privately-funded effort intended to begin training women to fly in NASA’s earliest space programs. The 13 women in the program undertook all of the training and testing that the seven men selected by NASA for the Mercury spaceflight program undertook.

Funk became the youngest woman to graduate from the program, and she was told she “had done better and completed the work faster than any of the guys,” she said during a promotional video about her participation in the Blue Origin flight.

Meanwhile, 18-year-old Oliver Daemen, a recent high school graduate who plans to attend the University of Utrecht in the fall, will become the youngest person in space.

He was a participant in the auction Blue Origin held for the final seat on the rocket, but he was not the top bidder. The mystery bidder — who put up a whopping $28 million and asked to remain anonymous — had to bow out because of “scheduling conflicts,” Blue Origin said last week.

A source familiar with the matter said Daemen’s spot was purchased for him by his father, Joes Daemen, who is the founder and CEO of Somerset Capital Partners, an investment firm based in the Netherlands.

Jeff Bezos and his brother Mark Bezos are the other two people flying in the rocket today.
