SpaceX's Dragon splashed into the Pacific, just five hours after leaving the orbiting lab.

"Welcome home, Dragon!" the California-based company said via Twitter.

After a one-month visit, the SpaceX cargo ship was set loose Sunday morning. Astronaut Steven Swanson, the station commander, released it using the big robot arm as the craft zoomed more than 260 miles above the South Pacific.

"Very nice to have a vehicle that can take your science, equipment and maybe someday even humans back to Earth," Swanson told Mission Control.

The SpaceX Dragon is the only supply ship capable of returning items to Earth. The others burn up on re-entry. This was the fourth Dragon to bring back space station goods, with 3,500 pounds (1,600 kilograms) aboard; it came down off Mexico's Baja California coast.

NASA is paying SpaceX and Virginia-based Orbital Sciences Corp. to make station deliveries. Orbital is next up, next month. Russia, Europe and Japan also make occasional shipments.
