Japan Aerospace Exploration Agency's Kounotori H-II Transfer Vehicle (HTV-6) approaches the International Space Station on Dec. 12, 2016. Expedition 50 astronauts successfully captured the 12-ton spacecraft using the station's Canadarm2 robotic arm. Robotic ground controllers then installed it on the Earth-facing side of the Harmony module. The unpiloted cargo spacecraft is loaded with more than 4.5 tons of supplies, water, spare parts and experiment hardware for the six-person station crew. The spacecraft, named 'Kounotori' -- Japanese for 'white stork' -- launched Friday, December 9, 2016 from the Tanegashima Space Center in southern Japan.
