Project TERRA is a student-led initiative at Concordia University focused on developing and testing a low-cost, simple, and throttleable rocket engine for research applications. Designed as a propulsion research platform rather than a flight-optimized system, the project enables controlled investigation of engine performance, stability, and behavior across a wide throttling range, with an emphasis on simplicity, affordability, and safe, repeatable testing.

As the space industry shifts toward reusable launch systems, engine throttling has become a key capability for improving mission flexibility and reducing costs. We aims to provide practical experimental insight into throttling behavior—an area where accessible test data remains limited—while supporting the development of more efficient, economical, and reliable rocket propulsion technologies and providing hands-on propulsion experience for students.
