Pale Blue Water Hall-effect thruster offers ideal balance of thrust and isp performances. It is a fully integrated system that incorporates thruster head, fluidics, electronics and propellant tank, and is clusterable to meet a wide range of mission requirements. The system is based on the traditional Hall thruster technology but is optimized to operate on water to receive additional benefits.

It does not require a high-pressure storage and the propellant is preloaded to the tank prior to delivery from factory so that satellite integrators would not have to deal with complex fueling work.

The propulsion system is planned to launch by 2027.
