The HTV 4 mission is also named Kounotori 4. Kounotori is the Japanese word for white stork. The fourth HTV mission is loaded with 11,900 pounds of equipment. About 8,600 pounds of cargo is riding inside the HTV's pressurized cabin, and engineers installed three items into the ship's unpressurized section. The HTV's exposed pallet also carries a U.S. military payload housing eight experiments in atmospheric observation, thermal control, radiation measurement, data processing and lightning research. The instruments, sponsored by the Defense Department and NASA, will be installed outside the space station for several years.
