The Axiom-4 Crew Dragon flight is scheduled to undock from the International Space Station to return four private astronauts after a couple-week science mission aboard the outpost.

Aboard is Axiom Space astronaut (and former NASA astronaut) Peggy Whitson, Indian astronaut Shubhanshu Shukla, Polish astronaut Slawosz Uznanski-Wisniewski, and Hungarian astronaut Tibor Kapu.

The four are expected to undock from the space-facing port of Harmony. About a day later, they will splash down in the Pacific Ocean off the coast of California.
