Video: Space station crew says goodbye to Japan cargo ship

International Space Station (ISS) astronaut Karen Nyberg of NASA used the Canadarm2 robotic arm to release the Japanese HTV-4 cargo ship on Wednesday, after its month stay at the orbital outpost.

The cargo craft, dubbed "Kounotori" --- the Japanese word for "white stork" --- by the Japan Aerospace Exploration Agency, arrived at the ISS Aug. 9 filled with more than three tons of supplies and spare parts for the crew. It will be commanded to deorbit on Saturday, headed for a destructive entry into the Pacific Ocean.
