PROJECT CAELUS

Taking the world's first high school liquid-fueled rocket to the edge of space.

Our Mission

Our mission at Project Caelus is to design, build, test, and launch a 3D printed liquid methane / liquid oxygen rocket engine to the edge of space, while also fostering workshops that introduce young kids to the ever-growing aerospace industry and teaching the community about the importance of STEM education in an increasingly technological world.

Our Work

Our work utilizes the some of the most modern, cutting-edge design and manufacturing techniques in the aerospace industry. Thanks to our generous sponsors and willful mentors, we're able to pursue every aspect of the engineering process with ever-growing confidence and efficiency.

Preliminary computational fluid dynamics (CFD) simulations to study the flow through our supersonic nozzle.
