We think our propulsion systems will push you to new heights... but don't take it from us, here are a few case studies performed in partnership with world-leading companies.

End-of-life Deorbiting & Collision Avoidance

+ View More

We all have to play nice space is our shared environment and we have a responsibility to make use of it sustainably. Is your platform ready to meet future deorbiting and collision avoidance regulations?

Constellation Deployment

We get it, Space is expensive! Flying to your destination has always been a tradeoff between budget ridesharing to the “middle of nowhere” or expensive dedicated launches. Not anymore!

Low Altitude Drag Compensation

If you’re in the Earth Observation business, flying low means getting more bang for your buck out of every pixel, but you can’t stay up there forever. Until now! (kind of)

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.
