About
The Pale Blue PBR-20 is a miniaturized water vapor propulsion system designed for small satellites, specifically in a 1U form factor. This system is fully integrated, incorporating the thruster head, fluidics, electronics, and propellant tank into a single unit. It utilizes water as a propellant, eliminating the need for high-pressure storage, which simplifies handling and integration. The propellant is preloaded into the tank at the factory, removing the need for complex fueling work by satellite integrators. The PBR-20 is clusterable, allowing it to be scaled to meet the propulsion needs of a wide range of spacecraft sizes. It has demonstrated in-orbit operation, with verification after two years in Low Earth Orbit (LEO) on a nanosatellite.
