Caelus Rocketry

The first high-school group to take a liquid-fuel rocket to space.


Caelus Rocketry (formerly known as Project Caelus) is an aerospace nonprofit consisting entirely of high school students. Our goal is to design, build, test, and launch the first high schooler-built bipropellant liquid-fueled rocket to the edge of space while creating opportunities that introduce our community to the ever-growing aerospace industry and the importance of STEM education in an increasingly technological world. Through our project, we hope to show young people that it’s possible to do something that has never been done before and that there is no age threshold to exploring science and pushing technological boundaries.
