Jeff Bezos in front of Blue Origin's space capsule
Dubbed the 'NewSpace' set, Jeff Bezos, Sir Richard Branson and Elon Musk all say they were inspired by the first moon landing in 1969, when the US beat the Soviet Union in the space race, and there is no doubt how much it would mean to each of them to win the 'new space race'.
Amazon founder Bezos had looked set to be the first of the three to fly to space, having announced plans to launch aboard his space company Blue Origin's New Shepard spacecraft on July 20, but Branson beat him to the punch.
The British billionaire became Virgin Galactic Astronaut 001 when he made it to space on a suborbital flight nine days before Bezos - on July 11 in a test flight.
Bezos travelled to space on July 20 with his younger brother Mark, Oliver Daemen, an 18-year-old physics student whose dad purchased his ticket, and pioneering female astronaut Wally Funk, 82.
Although SpaceX and Tesla founder Musk has said he wants to go into space, and even 'die on Mars', he has not said when he might blast into orbit - but has purchased a ticket with Virgin Galactic for a suborbital flight.
SpaceX became the first of the 'space tourism' operators to send a fully civilian crew into orbit, with the Inspiration4 mission funded by billionaire Jared Isaacman.
His flight was on a Dragon capsule and SpaceX rocket built by space-obsessed billionaire, Elon Musk and took off for the three day orbital trip on September 16 - going higher than the International Space Station.
SpaceX appears to be leading the way in the broader billionaire space race with numerous launches carrying NASA equipment to the ISS and partnerships to send tourists to space by 2021.
