What is happening and how to watch
Liftoff of the inaugural Blue Origin flight is scheduled for 9 a.m. ET from a rural complex just north of Van Horn, Texas.
In total, the flight will be 11 minutes, with approximately three minutes spent above the so-called Karman line that is defined by some as the boundary between Earth's atmosphere and outer space. After re-entry, the astronauts are set to descend back to Earth in their capsule with a parachute-landing in the west Texas desert.
ABC News will carry live coverage of the event, which will also be streamed on Blue Origin's website. The live broadcast will begin at 7:30 a.m. ET. Unlike most spaceflights, there are no on-site public viewing areas in the vicinity of the launch site. The newly-minted astronauts are set to have a press conference shortly after landing back on earth.
There is no pilot aboard the fully-autonomous capsule. While Blue Origin's New Shepard has flown 15 test flights, Tuesday's will be the first with humans on board.
The definition of "space" has emerged as a heated debate point in the new space race, as Sir Richard Branson took heat for not passing the Karman line (roughly 62 miles above earth) during his Virgin Galactic spaceflight earlier this month. Neither Blue Origin nor Virgin Galactic's flights will reach Earth's orbit, however, the way Elon Musk's SpaceX missions have. Musk, also a billionaire player in the new space race, on Twitter has called out this "big difference."
While the modern space race has become the arena of the ultra-wealthy at a time when a global pandemic on earth has exacerbated inequities, some argue the rise of private sector involvement has saved NASA money and accelerated technological advances -- which in the long-term has the potential to open up space tourism to all who have been curious about the cosmos.
In an interview with ABC News' "Good Morning America" just one day ahead of the spaceflight, Bezos said he is curious how briefly leaving Earth will "change" him.
"I don't know what it's going to mean for me," Bezos said. "I don't know, I'm very curious about what tomorrow is actually going to bring. Everybody who's been to space says it changes them in some way. And I'm just really excited to figure out how it's going to change me."
