A SpaceX Dragon cargo spacecraft is headed back to Earth.
The robotic Dragon undocked from the International Space Station (ISS) today at 12:25 p.m. EDT (1625 GMT), about 20 minutes later than originally planned. The departure occurred while the two spacecraft were flying about 260 miles (418 kilometers) above the northern Pacific Ocean, NASA officials said during today's undocking livestream.
The Dragon is expected to splash down in the Pacific Ocean off the coast of California on Wednesday (June 17), a little after 8 a.m. EDT (1200 GMT). You won't be able to watch, however; splashdown will not be webcast.

The capsule arrived at the ISS two days later, delivering nearly 6,500 pounds (2,950 kilograms) of food, scientific hardware and other equipment to the astronauts aboard the orbiting lab.
The freighter is hauling thousands of pounds of cargo back home as well, "carrying samples that could shape future space exploration and life on Earth," NASA officials wrote in a June 12 media advisory .
"Research returning includes bioprinted organ and cartilage tissue, data on improving cryogenic fuel storage for future space missions, and DNA‑inspired materials to develop new cancer treatments," they added. "The returning hardware includes an ocular imaging device used to monitor crew members' eye health, an absorbent bed that filters trace contaminants from cabin air, and a separator pump from the waste and hygiene compartment."

The other active freighters — Northrop Grumman's Cygnus, Russia's Progress and Japan's HTV-X — are all expendable, burning up in our air at the end of their missions.
