H-II Transfer Vehicle KOUNOTORI (HTV)
Summary of the ISS Cryogenic Experiment Storage Box (ICE Box) demonstration results
The ISS Cryogenic Experiment Storage Box (ICE Box) was developed in Japan and carried aboard the HII Transfer Vehicle KOUNOTORI4 (HTV4) on August 4, 2013. This is a cool box made to keep the cargo cool without the electrical power during a flight to the ISS.
The below graph shows that the storage box exceeds the requirement of maintaining the internal temperature within +4℃±2℃ for 10 days. The internal temperature was kept within the requirement for 12 days, and it maintained with only 1℃ increase for 10days. Thus, the ICE Box has demonstrated that it has enough capability of transferring refrigerated cargo aboard HTV.
