A wealthy space tourist and three fellow adventurers plunged back to Earth aboard a SpaceX Crew Dragon capsule Friday, splashing down in the Pacific Ocean off the coast of southern California to close out the first crewed flight around Earth's poles.

Led by cryptocurrency billionaire Chun Wang, who is the financier of this mission, the Fram2 crew has been free-flying through orbit since Monday. The group is now set to splash down off the coast of California — the first West Coast landing in SpaceX’s five-year history of human spaceflight missions.

The first four humans to orbit over Earth's north and south poles have safely returned to Earth.
