Amazon founder Jeff Bezos and Tesla founder and CEO Elon Musk had "friendly" meetings discussing space exploration before a rivalry between their respective aerospace companies, Blue Origin and SpaceX, blossomed, a new book reveals.
Bezos founded Blue Origin in 2000 while Musk created SpaceX in 2002. The two billionaires have flip-flopped between the No. 1 and No. 2 spots among the wealthiest individuals in the world in recent years.
Musk remembered "friendly" meetings with Bezos in the early 2000s while speaking to author Brad Stone for his new book released Tuesday, "Amazon Unbound," one of which resulted in "a technical debate with Bezos over the merits of Blue Origin’s planned fuel mix, which used peroxide, a compound known to decompose rapidly when exposed to sunlight," Stone wrote
"Peroxide is great until you come back one weekend and your vehicle is gone and your test site is gone," Musk told Stone.
Musk also told Stone that he "thought it was cool that Jeff created Blue Origin and that there was someone else with similar philanthropic goals with regard to space, and a lot of resources."
Bezos and Musk held private meetings twice, once in San Francisco and once in Seattle, with their spouses to discuss their "mutual obsession" with the future of aerospace technology such as reusable rockets, Stone wrote.
SpaceX became the first private company to fly NASA astronauts into space last year.
NASA in April of 2020 awarded both SpaceX and Blue Origin contracts for NASA’s Artemis program worth a combined $967 million over a 10-month base period to design and develop equipment for a program that aims to return humans to the Moon by 2024. A year later, NASA announced that it awarded a $2.9 billion contract to SpaceX to build the craft intended to transport U.S. astronauts to the lunar surface for the first time in decades.
Blue Origin filed a protest with the Government Accountability Office over the contract awarded earlier in April, The New York Times reported at the time.
