About
Pale Blue PBR-50 is a water vapor propulsion system in a Φ250 × 300 mm form factor, designed for MicroSats. It is a fully integrated system incorporating the thruster head, fluidics, electronics, and propellant tank, and is clusterable to scale to a wide range of spacecraft sizes. The PBR-50 uses water as propellant — no high-pressure storage is required — and the propellant is preloaded at the factory, eliminating complex fueling work for satellite integrators. The system produces 10 mN of thrust at 50 W and stores 4,400 Ns of total impulse.
