Update, October 19:  The launch has been postponed due to bad weather, which will last for several days so a new date is not being set for now.

The original HTVs were launched on Japan’s H-II rocket and “HTV” stood for  H-II Transfer Vehicle.  The H-II rocket has been replaced by the new H3. This will be the seventh flight of the H3.
