Jeff Bezos is going to blast off into space next month.

The Amazon founder announced today that he and his brother Mark will be the first people launched into space aboard a rocket built by his spaceflight company Blue Origin.

The 57-year-old billionaire broke the news on Instagram saying, "Ever since I was five years old, I’ve dreamed of traveling to space. On July 20th, I will take that journey with my brother. The greatest adventure, with my best friend."

Jeff and Mark will fly to the edge of space -- just high enough to get a great look at Earth -- before parachuting down and landing somewhere in West Texas. And they won't be entirely alone. They will be joined by the winning bidder of an online auction, which currently has a high bid of $2.8 million.
