Billionaire Jeff Bezos is set to board a space flight with his company, Blue Origin.

The flight will take off on July 20th, just 15 days after he is set to resign as CEO of Amazon.

It will also be somewhat special, with Blue Origin revealing Bezos’ younger brother, Mark Bezos, will also join the flight.

Bezos, 57, said in a Monday morning Instagram post. “On July 20th, I will take that journey with my brother. The greatest adventure, with my best friend.”

Battle of the billionaires

Blue Origin is a distant second in the public eye to Elon Musk’s SpaceX, but this appears to be one space race Bezos is likely to win.

If all goes according to plan, Bezos will be the first of the billionaire space tycoons to experience a ride aboard the rocket technology that he’s poured millions into developing.

The Amazon CEO announced Blue Origin will launch its new Sheppard rocket and capsule in July.

New Shepard is designed to carry as many as six people at a time on a ride past the edge of space, with the capsules on previous test flights reaching an altitude of more than 340,000 feet.

The Sheppard’s flights are “sub-orbital” meaning they will take passengers on a short trip into space and back down to earth.

The company says “only 569 people have ever been over the so-called Kármán Line in space… and it wants to change this and change it dramatically”

SpaceX also plans to launch people into space by Autumn this year. 

So the battle between the billionaires to turn their rockets to riches continues on.
