The Japan Aerospace Exploration Agency (JAXA) Kounotori 5 H-II Transfer Vehicle (HTV-5) is seen berthed to the International Space Station. The external CALET experiment, which will search for signatures of dark matter, is seen being extracted from the unpressurized section by the station's robotic arm, Canadarm2. The unpiloted cargo craft, named "Kounotori," which is Japanese for "white stork," is loaded with more than four-and-a-half tons of research and supplies, including water, spare parts and experiment hardware
