SpaceX cargo ship begins journey back to Earth

SpaceX's unmanned Dragon supply ship left the International Space Station Thursday and began its journey back to Earth where it will splash down in the Pacific Ocean off the coast of California, NASA said. "The release has been confirmed, right on time at 6:04 am Central Time (1104 GMT)," a NASA commentator said as the US space agency broadcast images of the white capsule floating away from the space station's robotic arm. Splashdown in the Pacific Ocean is expected at 1642 G
