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

SpaceX's private Fram2 mission splashed down today (April 4) at 12:18 p.m. ET (1618 GMT), softly parachuting down into the Pacific Ocean, off the coast of Oceanside, California. Their return wraps up about three and half days spent in space, completing the first crewed mission to fly a polar orbit around Earth. "We have confirmation of splashdown of the Dragon spacecraft. Dragon has returned home with the Fram2 crew," SpaceX officials said on the mission's livestream.
