HTV Technical Demonstration Vehicle
HTV-1, also known as the HTV Demonstration Flight or HTV Technical Demonstration Vehicle, was the first Japanese Space Agency (JAXA) H-II Transfer Vehicle, launched in September 2009 to resupply the International Space Station and support the JAXA Kibo laboratory or JEM. 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.
