It was an unmanned cargo spacecraft carrying a mixture of pressurised and unpressurised cargo to the space station. After a 52-day successful mission, HTV departed the ISS on 31 October 2009 after being released by the station's robotic arm. The spacecraft re-entered the Earth's atmosphere on 2 November and disintegrated on re-entry as planned. ==Payloads== HTV-1 carried four and a half tonnes of payload, lower than the six tonne maximum payload of the HTV in order to allow the spacecraft to carry additional propellant and batteries for the in-orbit verification phase of the flight.〔 〕 In the Unpressurised Logistics Carrier, the HTV-1 carried SMILES (Superconducting Submillimetre-Wave Limb Emission Sounder) and HREP (HICO-RAIDS Experiment Payload), which both were installed in the JEM Exposed Facility on the ISS.〔(【引用サイトリンク】title=JFY 2009 Summer Launch Season Launch/Operation and Control Plans for HTV/H-IIB TF1 )〕 The Pressurised Logistics Carrier carried 3.6 tonnes of supplies for the International Space Station.〔〔 〕 It consisted of food (33% of weight), laboratory experiment materials (20%), robot arm and other hardware for JEM (18%), crew supplies including garments, toiletries, personal mail and photographs, fluorescent lights, waste buckets (10%), and packing materials (19%). 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「HTV-1」の詳細全文を読む スポンサード リンク
