Jeff Bezos will be aboard for Blue Origin’s first human space flight next month.

In an Instagram post early on Monday, Bezos said he, his brother, and the winner of an ongoing auction, will be aboard Blue Origin’s New Shepard space craft during its scheduled launch on July 20.

July 20 is the anniversary of the Apollo 11 moon landing.

The trip will be a brief hop to space from Texas.

Mr Bezos said in early February that he was stepping down as chief executive of Amazon to spend more time, among other things, focused on Blue Origin.

“To see the Earth from space, it changes you, changes your relationship with this planet.

“It’s one Earth,” Mr Bezos said in the Instagram post.

“I want to go on this flight because it’s a thing I’ve wanted to do all my life.

“It’s an adventure.

“It’s a big deal for me.”

The auction for an open seat on New Shepard ends Saturday.

The winning bid right now stands at 2.8 million US dollars, with almost 6,000 participants from 143 countries.

The winning bid amount will be donated to Blue Origin’s foundation, Club for the Future, whose mission is to inspire future generations to pursue careers in STEM and to help invent the future of life in space.
