4 space tourists return to Earth after a private flight over the poles

Four space tourists who orbited the north and south poles returned to Earth on Friday, splashing down in the Pacific to end their privately funded polar tour.

Bitcoin investor Chun Wang chartered a SpaceX flight for himself and three others in a Dragon capsule that was outfitted with a domed window that provided 360-degree views of the polar caps and everything in between. Wang declined to say how much he paid for the three-and-a-half-day trip.

The quartet, who rocketed from NASA's Kennedy Space Center on Monday night, returned off the Southern California coast. It was the first human spaceflight to circle the globe above the poles and the first Pacific splashdown for a space crew in 50 years.
