Based on a building-blocks approach, ATHENA’s modular nature allows for a wide range of power scaling, from several Watts to 100s of Watts, depending on your mission requirements.


Attitude control may be achieved by adding additional thruster modules. Satellite pointing or reaction wheel desaturation is possible without gimbals or other complex approaches.


Total Impulse provided can be adjusted by varying the amount of on-board propellant. Never carry more than you need, or under-deliver; ATHENA propulsion systems are always just right.
