Propulsion System
The Patented Technology that Drives our Product Performance
Pale Blue offers advanced electric propulsion systems suited for a wide variety of missions for spacecraft ranging from 3U Cubesats to 700 kg satellites. The systems use water as propellant and do not require high pressure storage, which leads to a safe, cost-effective and sustainable solution for in-space propulsion.
Benefits of Water
-
Safe
The ultimate green propellant
-
Affordable
Water is the most affordable propellant to date
-
Sustainable
The most abundant resource on earth
