Next Generation Spacecraft Propulsion

Powering space mobility with water - the ultimate green propellant

The Company

Founded in 2020 by propulsion specialists at the University of Tokyo, Pale Blue seeks to disrupt the space propulsion industry by using water propellant to offer the world's safest high performance spacecraft thruster.
Powered by its patented miniturized ECR technology, Pale Blue thrusters are able to fully capitalize all of the ''green'' benenfits of water while still achieving unprecedented levels of high performance.

The Team

Pale Blue Inc. was founded by four members who have been engaged in basic research on propulsion machines, and the development and operation of the satellite-mounted actual machine together for more than 7 years.
Pale Blue Inc. is striving every day to realize sustainable space development and utilization centering on the technology of ultra-small propulsion system with water as the propellant.
