Building From Example

We’re using the Athena V2 Iteration V18 from Sketchfab as the starting point for exploring the design and control of an actively guided rocket. This detailed model helps us understand the fundamentals of rocket framing, control systems, and coding needed for stabilization and flight.

A big thank you to the original designers for sharing such an inspiring and well-crafted design. Your work sets the stage for learning, building, and innovation.

Thrust Vector Control in Dual-Axial Rockets

Thrust Vector Control (TVC) lets rockets steer by tilting their engines, changing the direction of thrust mid-flight. Used by SpaceX’s Falcon 9 and Starship, TVC replaces fins in space, guiding rockets with precision. Through dual-axis gimbals, simple trigonometry, and real-time control, rockets stay stable and on course. From large boosters to student-built models, TVC is the key to modern rocket control and reusable spaceflight.
