Saudi Arabia's first astronauts in decades rocketed toward the International Space Station (ISS) on a chartered multimillion-dollar flight Sunday.

SpaceX launched the ticket-holding crew, led by a retired NASA astronaut now working for the company that arranged the trip from Kennedy Space Center in Florida, U.S. A U.S. businessman who now owns a sports car racing team is also on board.

The four should reach the space station in their capsule Monday morning, and they'll spend just over a week there before returning home with a splashdown off the Florida coast.

Sponsored by the Saudi Arabian government, Rayyanah Barnawi, a stem cell researcher, became the first woman from the kingdom to go to space. She was joined by Ali al-Qarni, a fighter pilot with the Royal Saudi Air Force.

They're the first from their country to ride a rocket since a Saudi prince launched aboard shuttle Discovery in 1985.

"Hello from outer space! It feels amazing to be viewing Earth from this capsule," Barnawi said after settling into orbit.

Added al-Qarni: "As I look outside into space, I can't help but think this is just the beginning of a great journey for all of us."

Rounding out the visiting crew: Knoxville, Tennessee's John Shoffner, former driver and owner of a sports car racing team that competes in Europe, and chaperone Peggy Whitson, the station's first female commander who holds the U.S. record for most accumulated time in space: 665 days and counting.

"It was a phenomenal ride," Whitson said after reaching orbit. Her crewmates clapped their hands in joy.

It's the second private flight to the space station organized by Houston-based Axiom Space. The first was last year by three businessmen, with another retired NASA astronaut. The company plans to start adding its own rooms to the station in another few years, eventually removing them to form a stand-alone outpost available for hire.

The guests will have access to most of the station as they conduct experiments, photograph Earth and chat with schoolchildren back home, demonstrating how kites fly in space when attached to a fan.

"Our job is to expand what we do in low-Earth orbit across the globe," said NASA's space station program manager Joel Montalbano.
