A wealthy bitcoin entrepreneur 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.

Four private astronauts returned to Earth in a SpaceX capsule on Friday after roughly four days orbiting the planet in a novel polar trajectory, walking out of their spacecraft with little assistance to cap off the Elon Musk-led company's sixth fully private space mission.

The first crewed space mission to explore Earth’s polar regions is getting ready to head back home. The four-person Fram2 crew launched into orbit from the Kennedy Space Center on Monday. Their Crew Dragon spacecraft is scheduled to splash down off the coast of California at 12:19 p.m.
