"The Dragon is free."

Those were the words from mission commentator Rob Navias as the SpaceX's Dragon capsule successfully released from the International Space Station at 9:57 a.m. EST on Saturday.

The cargo capsule has been at the Space Station since it docked Sept. 23. The release came as the Space Station flew over the northwest coast of Australia.

It will splash down around 3:39 p.m. in the Pacific Ocean, just off the coast of Baja, California. It will be slowed by dual parachutes. A recovery team will then recover the capsule and bring it back to land.

The capsule will return to Earth with 3,200 pounds of cargo, including science samples and education efforts from NASA. The spacecraft's pressurized cabin will contain refrigerated blood, urine and saliva samples. There's also a habitat with 10 rodents and plants that were grown on the Space Station.

The Dragon launched onboard a Falcon 9 rocket Sept. 21, from the Cape Canaveral Air Force Station.
