After launch, the Japanese-built Kounotori 7 spacecraft will take several days to arrive at the International Space Station with its 6,000 kilograms of supplies, experiments and hardware.
Upon a nominal rendezvous, the spacecraft will maneuver itself to just 10 meters below the Destiny laboratory where the 17.7-meter Canadarm2 will be used to grab the vehicle and move it to the Earth-facing port of the Harmony module.
There it will remain attached for at least two months. During that time, the lithium-ion batteries in the Kounotori's unpressurized section will be removed and installed by astronauts on the outpost's integrated truss assembly, replacing the older nickel-hydrogen batteries.
The old batteries will be placed in the spacecraft's unpressurized compartment for disposal in the northwestern Pacific Ocean at the end of Kounotori 7's mission.
