SpaceX�s next private flight to the International Space Station awaited takeoff Sunday, weather and rocket permitting.

The passengers include Saudi Arabia�s first astronauts in decades, as well as a Tennessee businessman who started his own sports car racing team. They�ll be led by a retired NASA astronaut who now works for the company that arranged the 10-day trip.

It’s the second charter flight organized by Houston-based Axiom Space. The company would not say how much the latest tickets cost; it previously cited per-seat prices of $55 million.

With its Falcon rocket already on the pad, SpaceX targeted a liftoff late Sunday afternoon from NASA�s Kennedy Space Center. It’s the same spot where Saudi Arabia’s first astronaut, a prince, soared in 1985.

Representing the Saudi Arabian government this time are Rayyanah Barnawi, a stem cell researcher set to become the kingdom’s first woman in space, and Royal Saudi Air Force fighter pilot Ali al-Qarni.

Rounding out the crew: John Shoffner, the racecar buff, and Peggy Whitson, who holds the U.S. record for most accumulated time in space at 665 days.
