BREVARD COUNTY, Florida – SpaceX’s Axiom-2 mission took off from Kennedy Space Center on Sunday night, carrying the second all-private crew of astronauts on a multimillion-dollar journey to the International Space Station.

The mission for Houston-based company Axiom Space – contracted with NASA – is expected to last 10 days. The SpaceX Dragon “Freedom” capsule is slated to dock with the station at 9:30 a.m. EDT Monday and remain there for eight days before returning back to Earth.

The crew of four is commanded by former NASA astronaut Peggy Whitson, Axiom Space’s director of human spaceflight. She is joined by private spaceflight participant and mission pilot John Shoffner and the first two Saudi Arabian government-sponsored astronauts, mission specialists Ali Alqarni and Rayyanah Barnawi.

Axiom Space did not release how much Shoffner and Saudi Arabia are paying for the planned 10-day mission but the company had previously cited a ticket price of $55 million each.

Before liftoff, Whitson gave a few remarks that recognized the hard work of not only launch teams, but the thousands of people that it takes to make a crewed launch happen.

“Today, we stand on the threshold of a remarkable journey thanks to your unwavering spirit to explore beyond our home planet and the endless possibility it enables. Thanks to the teams that make up our very big family Axiom Space, NASA, the international space partners, and SpaceX,” Whitson said. “And with that, let’s get to work and build some history together.”

Shoffner, the only paying customer on the flight, is a businessman, aviator, and STEM advocate who was born in Alaska and now lives in Knoxville, Tennessee. He fills the pilot seat for the private mission since he is a veteran aviator with 25 years and more than 8,500 hours of flying experience.
