"The only way that I can see to deploy this much financial resource is by converting my Amazon winnings into space travel. That is basically it," Bezos says in an interview with Axel Springer CEO Mathias Döpfner, published by Business Insider on Saturday.
Bezos says his work on Blue Origin, his space company, "is the most important work that I'm doing."
"Blue Origin is expensive enough to be able to use that fortune," he says. "I am currently liquidating about $1 billion a year of Amazon stock to fund Blue Origin. And I plan to continue to do that for a long time. Because you're right, you're not going to spend it on a second dinner out."
On Sunday, Blue Origin successfully launched its New Shepard rocket for the first time in 2018 from its facility near Van Horn, Texas. The company hopes to send humans to space as early as this year, but CEO Bob Smith says that will only happen when the company is completely sure the travel will be safe.
Bezos shared a video of highlights of the launch on his personal Instagram.
