Sustainable space development and utilization
Pale Blue was founded in April 2020 as a spin-off company from the University of Tokyo. Four co-founders received Ph.D. from the University of Tokyo and have been studying for over a decade. Pale Blue’s core technologies are based on years of research at the University of Tokyo.
In 2014, we succeeded in the world’s first on-orbit operation of the micro-ion propulsion systems in low earth orbit and deep space. In 2019, the micro-water propulsion system was equipped with the 3U CubeSat and successfully deployed from the International Space Station.
Pale Blue’s water propulsion systems have high TRL (e.g. 7~9) and experiences in meeting the safety requirements of Japanese launch vehicles “H-IIA” “H-IIB” and ISS deployment.
Pale Blue provides a variety of water propulsion systems for CubeSatsor small/micro/nano-satellites as follows:
○ Ion thruster
○ Resistojet thruster (Electrothermalthruster)
◯ Unified thruster (both ion thruster and resistojet thrusters are integrated)
Besides, Pale Blue also provides a safety review package, customization, customer support, or developer kit.
