SpaceX's Polaris Dawn crew returns home

SpaceX's Polaris Dawn crew is home, capping off a five-day mission to orbit — which included the world's first commercial spacewalk — by splashing down in the Gulf of Mexico. The Crew Dragon capsule carrying four astronauts landed off the coast of Dry Tortugas, Florida, at 3:37 a.m. ET Sunday. The Polaris Dawn mission made history as it reached a higher altitude than any human has traveled in five decades. A spacewalk conducted early Thursday morning also marked the first time such an endeavor has been completed by a privately funded and operated mission. #CNN #News
