SpaceX’s Crew Dragon ‘Endeavor’ successfully docked with the International Space Station as planned on Sunday morning, marking another key milestone during this historic Commercial Crew demonstration mission it’s conducting with NASA. On board Crew Dragon were NASA astronauts Doug Hurley and Bob Behnken, the test pilots selected to be the first ever humans to fly on board SpaceX’s Crew Dragon, and the first people ever to make the trip to orbit aboard a spacecraft built by a private company.
