SpaceX on Sunday evening launched a commercial mission to the International Space Station carrying four people, including former NASA astronaut Peggy Whitson.

This “Axiom-2” mission was commanded by Whitson and carried a paying customer named John Shoffner, who served as pilot, as well as two Saudi Arabian mission specialists, Ali al-Qarni and Rayyanah Barnawi. Shoffner and the government of Saudi Arabia procured the seats on Crew Dragon from Axiom, a Houston-based spaceflight company that brokered the mission to the space station. Whitson is an employee of Axiom.

The crew of four is flying the second fully private mission to the International Space Station and will spend about a week on board the orbiting laboratory before departing for Earth—weather permitting—on May 30.
