HTV-6

NSSDCA/COSPAR ID: 2016-076A

Description

An unmanned cargo spacecraft launched to resupply the International Space Station.

HTV-6 carries about 5.9 t of cargo (including the support structure weight), consisting of 3.9 t in PLC (Pressurised Logistics Carrier) and 1.9 t in ULC (Unpressurised Logistics Carrier).

Cargo in the pressurized compartment includes 30 bags filled with potable water, food, crew commodities, CDRA Bed (Carbon Dioxide Removal Assembly), TPF (Two-Phase Flow) experiment unit, PS-TEPC (Position-Sensitive Tissue Equivalent Proportional Chamber) radiation measurement instrument, ExHAM (Exposed Experiment Handrail Attachment Mechanism), HDTV-EF2 hi-def and 4K camera, new J-SSOD (JEM Small Satellite Orbital Deployer), and CubeSats (AOBA-Velox III, TuPOD which comprises two TubeSats (Tancredo-1 (pt) and OSNSAT), EGG, ITF-2, STARS-C, FREEDOM, WASEDA-SAT3). Cargo by NanoRacks includes TechEdSat-5,[11] CubeRider, RTcMISS,NREP-P DM7, four Lemur-2. Additionally, the Blue SPHERES satellite of the MIT Space Systems Laboratory is being returned to the ISS for continued autonomous systems research.

Cargo in the unpressurized compartment consists of six Lithium-ion batteries and their associated adapter plates to replace existing nickel-hydrogen batteries of the ISS. Since each of the new Li-ion battery has a capability equivalent to two of the current Ni-H batteries, the six new batteries will replace twelve old batteries, out of the 48 existing batteries of the ISS.

On departure from the ISS, Kounotori 6 will carry 9 out of the 12 replaced old batteries which will be disposed by destructive reentry into Earth's atmosphere. The 3 remaining old batteries will stay on the ISS.
