Reaction Dynamics is advancing the development of an innovative, eco-friendly propulsion system aimed at enhancing satellite manoeuvrability, including collision avoidance, proximity operations, and satellite deorbiting. This technology is designed to be more efficient and easier to handle and produce, representing a significant leap in satellite propulsion.
Following a Canadian Space Agency (CSA) announcement of opportunity, Reaction Dynamics (Saint-Jean-sur Richelieu, Quebec) was recently awarded a contribution of $776,000 to support the on-orbit demonstration of its monopropellant propulsion unit, commonly referred to as a microthruster. This funding builds on Reaction Dynamics’ previous work with the CSA in the development of hybrid rocket technology, which directly contributed to this in-space propulsion advancement.
The demonstration will evaluate key performance parameters for space operations such as orbit maintenance, altitude adjustments, inclination changes, collision avoidance and controlled atmospheric re-entry. The ability to execute these manoeuvres with greater precision and agility will refine mission profiles and contribute to space sustainability, particularly by enabling more efficient deorbiting processes.
The microthruster is designed to improve satellite agility by delivering high-density impulse while reducing environmental impact compared to conventional propulsion systems. It features 3D-printed components and is offered as a fully integrated unit, resulting in lower production costs, reduced resource requirements, and easier integration for customers. The flight heritage gained through this demonstration is a critical step toward the commercialization of the technology.
The CSA‘s financial support for this project comes through its Space Technology Development Program, reinforcing Canada’s commitment to advancing sustainable and innovative space technologies.
