HTV7 Mission

Developed and built in Japan, the H-II Transfer Vehicle (HTV) known as "KOUNOTORI (meaning ‘white stork’ in Japanese)" is an unmanned cargo transfer spacecraft that delivers supplies to the International Space Station (ISS). With the world’s largest loading capacity of approximately six metric tons and such unique functions as the International Standard Payload Racks (ISPRs) and unpressurized cargo transport, “KOUNOTORI” plays a key role in stable ISS operations through its steadily performing systematic resupply mission.
