Accompanying the billionaire are Bezos’ brother, Mark, “Mercury 13” aerospace pioneer Wally Funk and Netherlands native and first commercial customer Oliver Daemen.
Funk, 82, and Daemen, 18, will become the oldest and youngest people to go to space.
Blue Origin announced the addition of Daemen last Thursday in place of an auction winner that bid $28 million for the seat but had “chosen to fly on a future New Shepard mission due to scheduling conflicts.”
In a news briefing Sunday in West Texas, Blue Origin representatives said astronaut training would be completed Tuesday.
“Based on practice training with stand-in astronauts, we are fully confident that our astronauts will be ready to fly on Tuesday,” Blue Origin lead flight director Steve Lanius said. “Our training is comprehensive and gets crew prepped for everything they need to know about the vehicle.”
He added that the spaceflight company’s astronaut training was fully compliant with Federal Aviation Administration (FAA) requirements.
Training lasts for 14 hours during a two-day span and includes classroom instruction, demonstrations and practice in a training capsule.
It also covers nominal, off-nominal and emergency procedures, including zero GC ingress and egress, emergency egress and fire response and emergency breathing mask usage.
“The training culminates in mission rehearsals covering five different scenarios and a final exam,” Lanius said, adding that he would receive a report confirming that the astronauts were “go” for rollout and launch.
Speaking during the first minutes of the event’s livestream, Blue Origin senior director Gary Lai said the capsule had been designed for nonprofessional astronauts with little training experience.
The trip also follows 15 successful uncrewed test flights to space by New Shepard rockets since 2015.
In total, the flight will last for around 11 minutes, and Bezos is shooting for an altitude of around 66 miles – above the Kármán line and past Virgin Galactic’s Richard Branson’s flight earlier this month.
Liftoff is set for 9 a.m ET and can be viewed on the Blue Origin website or YouTube account.
