According to NASA, the descent capsule of the spacecraft with the astronauts, following the deployment of all parachutes, splashed down on November 8 at 22:33 US East Coast time in the Gulf of Mexico.
On board were NASA astronauts Megan MacArthur and Shane Kimbrough, European Space Agency (ESA) astronaut Thomas Peske and Japan Aerospace Exploration Agency (JAXA) astronaut Akihiko Hoshide.
This was the second regular flight into orbit by an American manned reusable spacecraft developed by SpaceX.
Earlier, Vladimir Dubinin, deputy chief of the Cosmonaut Training Center (CPC) for Science and Development, said that Roscosmos and NASA had compiled a preliminary list of Russian cosmonauts who will be trained on the Crew Dragon spacecraft as part of future "cross" flights to the International Space Station.
