Kounotori 9 (こうのとり9号機), also known as HTV-9 will be the 9th flight of the H-II Transfer Vehicle, a robotic cargo spacecraft to resupply the International Space Station.[2][3] It was launched on 20 May 2020, at 17:31:00 UTC.[4]

Kounotori 9 will be the last HTV of the original model, with following missions replaced with the HTV-X.[2][5]

Spacecraft

Major difference from the previous Kounotori are:[6]

  • Camera assembly unit and Wireless LAN communication unit to demonstrate communication in the proximity of ISS for the real-time video monitoring of approach. It is a technology demonstration for use with HTV-X and Gateway.

Wireless LAN Demonstration

Wireless LAN Demonstration, or WLD (pronounced wild)[6] is an experiment that will be performed during Kounotori 9's flight. During the test, a video taken by Kounotori 9 will be broadcasted in real time on board the space station, via a wireless LAN (WLAN) datalink.[7] The experiment will be conducting during Kounotori 9's approach, departure, and while berthed to the ISS.[8] For WLD, the spacecraft has a camera attached to its propulsion module, while a data processor and WLAN antenna is located at the Unpressurized Logistics Carrier's aperture.[6] The technology to be tested by WLD will enable ISS crews to monitor approaching vehicles during an autonomous docking.[9] According to JAXA, if successful this will be the first time for two spacecrafts to communicate using WLAN during a rendezvous.[6]

Cargo

Kounotori 9 will carry about 6200 kg of cargo, consisting of 4300 kg in the pressurized compartment and 1900 kg in the unpressurized compartment.[6]

Cargo in the pressurized compartment (Pressurized Logistics Carrier, PLC) is, in addition to the foods and crew commodities:[6]

  • JAXA cargo:
    • Solid Combustion Experiment Module (SCEM)
    • Integrated Standard Imager for Microsatellites (iSIM), a commercial technology demonstration payload by Spanish company Satlantis
    • Equipment for the space media business collaboration (Space Frontier Studio KIBO)
    • Confocal Space Microscopy (COSMIC)
  • NASA cargo:

Cargo in the unpressurized compartment (Unpressurized Logistics Carrier, ULC) are the six lithium-ion batteries Orbital Replacement Units (ORUs) for replacing the ISS's existing nickel-hydrogen batteries. This is the last of the series of transportation of replacement batteries, following the previous Kounotori 6, Kounotori 7, and Kounotori 8.

Operations

Launch

Kounotori 9 is to be launched aboard H-IIB on 20 May 2020, at 17:31:00 UTC.[1]
