HTV-1, also known as the HTV Demonstration Flight[4] or HTV Technical Demonstration Vehicle,[5] was the first flight of the Japanese Space Agency (JAXA) H-II Transfer Vehicle, launched in September 2009 to resupply the International Space Station and support the JAXA Kibō module (きぼう, Kibō, Hope) or Japanese Experiment Module (JEM). It was an uncrewed cargo spacecraft carrying a mixture of pressurised and unpressurised cargo to the International 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 in the atmosphere of Earth on 1 November 2009 and disintegrated on re-entry as planned.
