A SpaceX cargo ship laden with science departed the space station and headed back toward Earth, Report informs referring to Space.com.

SpaceX's robotic Dragon spacecraft undocked from the International Space Station (ISS) on December 21 at 5:05 p.m. EST (2205 GMT), as the two spacecraft were flying over the southwest coast of Chile.
If all goes according to plan, Dragon will splash down late December 22 off the coast of Tallahassee, Florida, NASA officials said. The splashdown will not be livestreamed.

The departure was originally scheduled for December 14, but it was delayed repeatedly due to bad weather in the splashdown zone.

The CRS-29 Dragon craft arrived at the space station on November 11 carrying 6,500 pounds (nearly 3,000 kilograms) of supplies for ISS astronauts, along with a laser experiment.

Dragon is bringing home to Earth about 3,500 pounds (1,588 kg) of science and hardware, NASA officials wrote in a blog post last week. Also inside Dragon are cargo bags, bearing hardware and some trash.
