The success is total for the first orbital mission in history to have no professional astronaut on board.
SpaceX's first four space tourists landed in the Atlantic Ocean off the coast of Florida on Saturday evening after spending three days in space.
The Dragon capsule resisted the vertiginous descent thanks to its heat shield, then was slowed down by four huge parachutes.
The landing took place on time, a little after 7 p.m. on the US East Coast (1 a.m. in Paris), according to a video broadcast from Elon Musk's company.
A SpaceX ship had to retrieve the capsule, before the hatch was opened and passengers could finally exit.
They should then be transported by helicopter to the Kennedy Space Center, from where they took off aboard a Falcon 9 rocket on Wednesday evening.
" It is just beginning "
“It was a hell of a trip for us, and it's only just beginning,” captain billionaire Jared Isaacman said shortly after the landing.
The stated goal of the mission, called Inspiration4, was to mark a turning point in the democratization of space, by proving that the cosmos is also accessible to crews who have not been handpicked and trained for years.
The four novices spent three days in orbit around the Earth, traveling beyond the International Space Station (ISS), up to 590 km above sea level.
Spinning in orbit at around 28,000 km / h, they circled the globe more than 15 times each day.
