, also known as HTV-6, will be the sixth flight of the H-II Transfer Vehicle, an unmanned cargo spacecraft launched to resupply the International Space Station. This is the second to last Kounotori flight of the originally planned 7.〔 〕 As of early 2015, it is planned to be launched in 2016. ==Spacecraft== Kounotori 6 will test several new technologies. The mission will test thin film solar cells in space.〔 〕 A reentry capsule, essentially a miniaturized HTV-R capsule, will be carried in the pressurized section.〔 〕 This HTV flight will also have an experimental electrodynamic tether (EDT).〔 〕〔 〕 The tether is equipped with a 20 kg end-mass, and will be 700 m long when deployed. A maximum 10 mA current will run through the tether. Kounotori's ISS rendezvous sensor will be utilized to measure how the end-mass moves during the test. The EDT experiment will be conducted following Kounotori 6's departure from the ISS, and is to be held for a week. After the experiment, the tether will be separated before the spacecraft proceeds with the de-orbit maneuvers. The main objective of this experiment is the orbital demonstration of both extending an uncoated bare-tether, and driving electric currents through the EDT. These two technologies will contribute to gaining capabilities to remove space debris. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kounotori 6」の詳細全文を読む スポンサード リンク
