Four civilians who went to orbit the Earth aboard the US space exploration company SpaceX have returned to Earth after a three-day trip.



Space tourists set off on the Atlantic Ocean near Florida, just after 7 p.m. Eastern time on the 18th local time.



Billionaire Jared Isaacman, nurse Haley Arseno, university science instructor Sian Procter, and Iraq war veteran Chris Sembrosky flew into space on the night of the 15th in the SpaceX spacecraft 'Crew Dragon'.



They reached space 160 kilometers higher than the International Space Station and orbited the Earth for three days.
