Message from JAXA President
Completed mission of the "KOUNOTORI8" ("HTV8")

Today, on November 3, 2019, the H-II transfer vehicle "KOUNOTORI8" ("HTV8") left the orbit and reentered the atmosphere as scheduled.
After successfully docking to the International Space Station (ISS) on September 29, 2019, "KOUNOTORI8" had stayed aboard the ISS for approximately 34 days. While docked, resupply items and utilization cargo which are inevitable for ISS operations were transferred to the ISS, and after being loaded with trash material, the "KOUNOTORI8" had successfully re-entered the Earth atmosphere today. This marked the eighth consecutive mission success.

Following the preceding two "KOUNOTORI" (HTV6 and HTV7), the HTV8 transported without fail to the ISS the cargoes which were indispensable for operations of the ISS, including new batteries based on Japan-made lithium-ion batteries and which only the vehicle "KOUNOTORI" was capable of carrying. The HTV8 also delivered several experiment devices such as SOLISS (Small Optical Link for International Space Station), Hourglass (Dependence Research of Flexible Surface on a Planet) and JSSOD#12 (JEM Small Satellite Orbital Deployer) for use in experiments on the Japanese Experiment Module "Kibo." The initial checkout has been completed for SOLISS.

The star tracker, newly introduced in the "KOUNOTORI8"'s mission, enabled it to constantly perform its attitude control in a perfect manner. The newly developed resupply rack greatly increased the payload loading capacity. These achievements demonstrated the effectiveness of the new technologies adopted before the new ISS transfer vehicle "HTV-X" currently being developed is commissioned.

"KOUNOTORI 9" ("HTV9"), transfer vehicle scheduled for the next fiscal year is the final mission for current "KOUNOTORI". We will aim for a successfully complete "KOUNOTORI9"'s mission with the technologies we have accumulated and enhanced, and make efforts to steadily transfer the technologies to the successor HTV-X.

I would like to express my thankfulness to many people from domestic and international organizations and agencies and many individuals who provided us precious support and assistance.

JAXA | 宇宙航空研究開発機構

20 апр. 2020 г.

The H-II Transfer Vehicle (HTV or KOUNOTORI) is an unmanned spacecraft developed by the Japanese space agency JAXA for transporting cargoes to the International Space Station (ISS). The HTV has been and is being operated by JAXA. All the HTVs to date have successfully completed their missions. The HTV has a world-largest supply capability. This video image traces the general itinerary of the HTV8's mission.
■ Overview of the HTV8's mission
The HTV8 not only transported devices that could be required for growing use of space and testing future space exploration technologies. It was also used as a platform for technical demonstrations for development of the planned new model of transfer vehicle "HTV-X."
A new model of cargo rack which had been designed for boosting the vehicle's cargo transportation capability was subjected to the technical demonstration tests. The results of the tests showed a 30 percent increase in the carrying capability. Also, a star tracker (star sensor) was used as attitude control sensor instead of the conventional earth sensor in consideration of an enhancement of the cargo transportation capability in space from the low earth orbit to the close side of the Moon. Thus, an achievement of adequate and constant attitude control was verified.
