The First Student-Built Liquid-Fueled Rocket in Space

Stellar Aerospace is an independent, student-run rocketry team building in the University of Illinois Urbana-Champaign community. We are designing, building, and testing a liquid-propellant rocket built to be the first student-built, liquid-fueled vehicle to reach space.

Our Mission

Not officially affiliated with the University of Illinois, our team is independently pursuing goals no student rocket team has reached before.

First Liquid-Propellant Launch

The first liquid-propellant rocket designed, built, and launched entirely by students.

Reaching Space

The first student-built, liquid-fueled rocket to cross the boundary of space.

Largest Student Rocket

The largest rocket ever designed and built by a student team.

Highest Altitude

The highest altitude reached by any student-built rocket.

Highest Thrust

The highest thrust ever produced by a student-built rocket engine.

Highest Speed

The highest speed ever reached by a student-built rocket.

The Rocket

Codename: The Guinea Pig. Every subsystem, from propulsion to recovery, is designed and tested in house.

Rendering of the Stellar Aerospace launch vehicle

The Engine

A liquid-propellant engine designed for high performance with a manufacturable, low-complexity architecture.

Rendering of the engine's Inconel-718 shell

Inconel-718 Shell

The outer shell of the engine is 3D printed from Inconel-718, a nickel superalloy chosen for its strength at high temperature and its ability to hold a geometry tuned for performance.

Rendering of the engine's ablative cooling system

Ablative Cooling

An ablative liner absorbs and carries away extreme heat without complex regenerative plumbing. Prioritizing simplicity lets this engine set a new standard for manufacturable, single-use propulsion.

Join the Team

We are assembling our founding team in the University of Illinois Urbana-Champaign community. If you want to design, build, and fly real hardware alongside other students, we want to hear from you. No prior rocketry experience required, just a willingness to learn fast and build things right.

Propulsion Engineering

Design, simulate, and test the liquid-propellant engine, from injector to nozzle.

Structures & Manufacturing

Design the airframe and fabricate flight hardware to survive launch, ascent, and recovery.

Avionics & Recovery

Build the flight computer, telemetry, and parachute recovery systems that bring the vehicle home.

Software & Controls

Write the ground station, telemetry pipeline, and control software that flies the mission.

Safety Engineering

Own hazard analysis, test procedures, and range safety for every hot fire and launch.

Business & Sponsorship

Lead fundraising, sponsor relationships, budgeting, and outreach that keeps the team flying.

Media & Public Relations

Document the build, run our social channels, and tell the story of the team.

Operations

Coordinate schedules, test logistics, and the workspace that keeps the team moving.

Something Else?

Bring a skill we have not listed. If it helps us build and fly, we want to talk to you.
