The next time an H-IIB rocket launches from the island of Tanegashima in southern Japan, it will carry a cargo craft bound for the International Space Station (ISS). The H-II Transfer Vehicle, or HTV, weighs 10,500 kilograms (11.6 tons) and can carry about 6,000 kilograms (6.6 tons) worth of supplies for the astronauts aboard the ISS. This massive, cutting-edge spaceship plays an important role in the life of the orbiting station, but its development can be traced back to one man and one little object.
