A high bid of $28 million won the auction for a seat aboard Blue Origin's New Shepard rocket trip to the edge of space in July, the company announced Saturday.

The high bidder in the monthlong auction would be revealed in the upcoming weeks, it tweeted, and will be joined by Blue Origin owner Jeff Bezos and his brother, Mark, for the ride scheduled on July 20.

Though the Blue Origin rocket-propelled capsule can handle six passengers, this trip will be for four, and a fourth rider will also be announced at a later time, the company said.
