Crew Dragon is a part of the Dragon 2, a class of reusable spacecraft developed and manufactured by American aerospace manufacturer SpaceX.
It is the 5th class of US spacecraft to take human beings into orbit, after the Mercury, Gemini, Apollo and Space Shuttle programs.
Falcon 9, which carried the spaceship into the orbit, was also built by SpaceX.
It is done under the Demo-2 Mission of NASA and SpaceX.
The Demo-2 mission is part of NASA’s Commercial Crew Program with the aim of developing reliable and cost-effective access to and from the International Space Station.
It was the first splashdown by U.S. astronauts in 45 years, with the first commercially built and operated spacecraft to carry people to and from orbit.
The last time NASA astronauts returned from space to water was on July 24, 1975, in the Pacific to end a joint U.S.-Soviet mission known as Apollo-Soyuz.
