The SpaceX Dragon spacecraft splashed safely into the Pacific Ocean Saturday afternoon, after being released from the robotic arm of the International Space Station, in orbit over 250 miles above the northwest coast of Australia. The entire journey from space to water took around six hours.

“The Dragon is free,” said NASA commentator Rob Navias during a live broadcast on NASA TV, according to Reuters and the Universe Today. “The release was very clean.”

During its journey back to earth, the free-flying spacecraft carried with it 3,276 pounds of NASA cargo and science samples from the International Space Station. The samples included data from “human research, biology and biotechnology studies, physical science investigations, and education activities sponsored by NASA and the Center for the Advancement of Science in Space, the nonprofit organization responsible for managing research aboard the U.S. national laboratory portion of the space station,” said NASA, according to Universe Today.

The Dragon began this latest mission on September 21, blasting off from SpaceX’s Launch Complex at Cape Canaveral, FL with the help of a Falcon 9 rocket. It reached the International Space Station on September 24, delivering nearly 5,000 pounds of critical supplies and science experiments to the Astronauts aboard.

In 2012, the SpaceX Dragon made history when it became the first commercial spacecraft to successfully deliver cargo to the International Space Station and return. Currently, the Dragon is only spacecraft capable of carrying significant amounts cargo back to Earth. Though now a cargo ship, the Dragon was always intended to carry humans. Under an agreement with NASA, SpaceX is currently developing the necessary design refinements and Dragon’s first manned test flight is expected to take place in 2-3 years.
