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.

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

The Fram2 mission, paid for and led by a cryptocurrency billionaire who is flying with three guests, is on track to return after a journey on a unprecedented polar orbit.
