H-II Transfer Vehicle KOUNOTORI (HTV)

HTV9 Payload

Last Updated: May 14, 2020

HTV9 delivers a total of 6.2 metric tons (in the Pressurized Logistics Carrier (PLC) 4.3 metric tons and in the Unpressurized Logistics Carrier (ULC) 1.9 metric tons) supplies to the ISS.

Major supply goods to be delivered on board are as follows:

Utilization/experiment related items

Solid Combustion Experiment Module (SCEM)

Solid Combustion Experiment Module (SCEM)

The Solid Combustion Experiment Module (SCEM) is a device to be used for the FLARE project (Flammability Limits at Reduced Gravity Experiment). This project will be implemented to scientifically determine the role of gravity in different modes of combustion such as ignition of solid materials and spreading of flames on various solid materials in the ISS's environment without natural convection (microgravity environment).

integrated Standard Imager for Microsatellites (iSIM)

The integrated Standard Imager for Microsatellites (iSIM) is an earth observation camera being developed by a Spanish space venture company, Satlantis, which will be mounted on CubeSats or microsatellites. For the purpose of on-orbit demonstration, an iSIM will be installed on the IVA-replaceable Small Exposed Experiment Platform (i-SEEP). It is capable of taking high-resolution pictures of the Earth surface. The Tsukuba Space Center will send to the on-orbit computer a schedule file for the iSIM's automatic reading. The iSIM will take pictures according to the schedule. Pictures taken will be downlinked to the Tsukuba Space Center and transferred to Satlantis.

Materials related to space media business (for private purposes)

The basic components of the studio constructed for demonstration are a window of the Japanese Experiment Module "Kibo" facing the Earth (main view) and nearby tablet terminals. Technical demonstration tests will be conducted of the world unprecedented face-to-face two-way live streaming system, using a new dedicated ISS/Earth data communication protocol and a newly developed two-way communication application that can be activated in a short time. Demonstration tests in view of commercialization will also be conducted. These tests will be supported by some of the devices available on "Kibo." The HTV9 (KOUNOTORI9) will transport materials including an ND filter (used for adjusting the luminance between images on the tablet screen and the Earth image seen through the window), cables and fixing devices, which are indispensable for opening the Kibo Space Broadcasting Station as a space media business and exploitable for various future projects.

Cargo for the ISS crew

Fresh food

HTV9 will also deliver fresh food.

Cargo on the Unpressurized Logistics Carrier (ULC)

ISS battery Orbital Replacement Units (ORUs)

Exposed pallet (EP) loated with battery ORUs

Following HTV6, HTV7, and HTV8, HTV9 delivers new lithium ion batteries for the ISS. The batteries are delivered on the Exposed Pallet (EP), placed on the Unpressurized Logistic Carrier (ULC).
The new six battery Orbital Replacement Units (ORUs) consist new lithium-ion battery cells manufactured by a Japanese company.
The nickel-hydrogen batteries currently used on the ISS are becoming old. The extension of ISS operations becomes possible with the supply of Japanese lithium-ion battery cells. Only the HTV is capable of delivering six battery ORUs at one time, and thus plays an important role in continuous ISS operations.
