Kounotori 7 (こうのとり7号機), also known as HTV-7 will be the seventh flight of the H-II Transfer Vehicle, an unmanned cargo spacecraft set to launch on 2 February 2018 to resupply the International Space Station.[2][3][1]

Reentry capsule

This Kounotori flight is planned to test a reentry capsule, similar in function to the VBK-Raduga carried onboard Progress flights to the Mir space station. Essentially a miniaturized HTV-R capsule, it will be carried in the pressurized section of the vehicle.[4] On 22 October 2015, a high-altitude drop test of the capsule was successfully conducted off the coast of Taiki, Hokkaido.[5]
