How we Inspire Many
Sigma Unlimited is an innovation-driven platform where aspiring engineers and creators explore the intersection of engineering, environmental science, and 3D printing to design sustainable solutions for both Earth and space. Our mission is to inspire the next generation of thinkers and builders through hands-on projects, educational initiatives, and real-world applications.
Through signature programs like "The Space Above Us" and "The World Around Us," we connect the dots between the systems that shape our planet and the technologies that can protect or advance it. Whether developing eco-conscious designs, prototyping new space tech, or understanding the environmental impact of our creations, Sigma Unlimited empowers young minds to think beyond boundaries and build with purpose.

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.
