ISS Cryogenic Experiment Storage Box (ICE Box) was developed in Japan and carried aboard the HII Transfer Vehicle KOUNOTORI4 (HTV4) on August 4, 2013.
The HTV4 delivers about 5.4 metric tons of supplies to the ISS, including newly developed Freezer-Refrigerator of Stirling Cycle (FROST) and experiment samples to be conducted on the Japanese Experiment Module "Kibo." In addition, HTV delivers unpressurized Orbital Replacement Units (ORUs) the Unpressurized Logistics Carrier (ULC), which is one of the features of HTV, thus contributing to the maintenance and operation of the ISS.
HTV development was completed in the HTV3, which was launched in 2012, as the domestic production of major components was sufficiently advanced. Through the process of manufacturing HTV in Japan, technology which is imperative for inter-orbit transportation, cost reduction, and stable procurement become possible. Henceforth, basic design of the HTV4-7 is same with the HTV3. The differences are described in the detailed page.
