About: AQT-D

AQT-D (Aqua Thruster-Demonstrator) was a nanosatellite project of the University of Tokyo (UT) Space Propulsion Laboratory with the purpose of testing water-fueled propulsion. The satellite was a CubeSat of 3U size; 1U was occupied by the propulsion system, while the remaining 2U was for the spacecraft bus. AQT-D was carried to space inside the pressurized section of Kounotori 8, a Japanese resupply vehicle for the International Space Station (ISS). Kounotori 8 was launched on 24 September 2019. After arriving at the ISS, AQT-D was deployed to space on 20 November 2019 using the JEMRMS robotic arm at the space station's Kibō laboratory module.
