The successful launch and return of the mission, the latest in a recent string of rocket-powered expeditions bankrolled by their billionaire passengers, marked another milestone in the fledgling industry of commercial astro-tourism, 60 years after the dawn of human spaceflight.
"Welcome to the second space age," Todd "Leif" Ericson, mission director for the Inspiration4 venture, told reporters on a conference call after the crew returned.
SpaceX, the private rocketry company founded by Tesla Inc (TSLA.O) electric automaker CEO Elon Musk, supplied the spacecraft, launched it, controlled its flight and handled the splashdown recovery operation.
The three-day mission ended as the SpaceX Crew Dragon capsule, dubbed Resilience, parachuted into calm seas around 7 p.m. EDT (2300 GMT), shortly before sunset, following an automated reentry descent, as shown during a live SpaceX webcast on its YouTube channel.
