SpaceX readies private launch of four astronauts to International Space Station

Four crew members are set to launch Wednesday on a privately funded mission to the International Space Station.

The flight, organized by the Houston-based company Axiom Space, is slated to lift off at 8 a.m. ET from NASA’s Kennedy Space Center in Florida. The foursome will journey into orbit in a SpaceX Crew Dragon capsule atop a Falcon 9 rocket.

NASA will broadcast live coverage of the launch beginning at 7:05 a.m. ET on NASA+.

The flight was scheduled to launch Tuesday but high winds along the Florida coast forced a one-day delay. The mission, known as Ax-4, is expected to last about two weeks at the International Space Station.

The mission will be led by retired NASA astronaut Peggy Whitson, who has already logged a record 675 days in space — more than any other American astronaut. Joining her will be pilot Shubhanshu Shukla, an astronaut with the Indian Space Research Organization; mission specialist Sławosz Uznański-Wiśniewski, a Polish scientist with the European Space Agency; and mission specialist Tibor Kapu, a mechanical engineer from Hungary.

Shukla, Uznański-Wiśniewski and Kapu will make history by becoming the first people from their countries to live and work on the International Space Station.

During their two-week stay at the orbiting lab, the Ax-4 crew members will conduct a host of scientific experiments, according to NASA, including studies of muscle regeneration, how sprouts and edible microalgae grow in microgravity and how tiny aquatic organisms survive at the ISS.

If the launch goes according to plan, the four astronauts will dock at the space station on Thursday at around 12:30 p.m. ET.

The upcoming flight will be Axiom Space’s fourth crewed mission to the International Space Station. The company’s first private expedition to the ISS was in 2022 with an all-civilian crew.

The price tag for the Ax-4 mission has not been publicly disclosed, but space tourists reportedly paid around $55 million per seat on previous Axiom Space expeditions.
