Introducing Reaction Dynamics.
Founded in 2017, we are pioneering hybrid propulsion with a patented rocket technology that simplifies operations, cuts launch costs, and enables sovereign access to space. Today, we are Canada's most advanced rocket company, with a maiden suborbital space launch scheduled for 2026 and a first orbital launch scheduled for 2028.
Our mission
To reshape access to space with a new generation of hybrid launch vehicles — delivering rapid, routine, and sovereign access to orbit on timelines aligned with commercial and defence needs.
Our commitment
To ensure unmatched operational flexibility for both commercial space innovation and national security.

Enabling an era of hybrid propulsion
A 90-year old challenge. Solved.
Hybrid rockets, which feature both liquid and solid propellant, are known for their simplicity and low-part count. But for nearly a century, their commercialization was blocked by challenges in overcoming stable performance. Until now... Having solved the challenge of stabilizing the oxidizer-to-fuel ratio during combustion, we are unlocking a new generation of launch capability.
Reliable, flexible, ready to launch
Our breakthrough allows our rockets to leverage hybrid technologies to reach space, unlocking the advantages of hybrids without their traditional limits. By simplifying fuel handling and lowering operational risks, we deliver greater reliability, flexibility, and cost-effectiveness. The result is responsive access to space with propulsion designed for performance and practicality.
Pioneering a breakthrough

2026: a breakthrough year
Aurora takes flight
Scheduled for a demonstration launch in 2026, RDX's Aurora demonstrator will be the first hybrid rocket to reach space. It will leverage unique characteristics of hybrid rockets to ensure complete operational flexibility for both commercial and defence sector launches.
Leading a new era in space-access
With Aurora‑1 preparing to fly in 2026 and our orbital pathfinder on the horizon for 2028, Canada’s path to sovereign launch is no longer a distant ambition, but a reality being designed, engineered and built at RDX. The countdown has begun.
October 2025
RDX and Space Machines Company (Australia) sign a pivotal MOU advancing responsive space operations, combining on-demand launch with in-orbit inspection and servicing. We were honored to sign in the presence of Canadian Space Agency President, Lisa Campbell.
