ROLLA, Mo. — Members of Missouri University of Science and Technology’s Rocket Design Team made university history with the successful launch of their liquid-fueled rocket, Phoenix, this June. According to the team, they are the fifteenth team in the United States and the twentieth worldwide to launch a student-built liquid-fueled rocket.
One of the team members is Gavin Boehme, a senior in mechanical engineering from Altenburg.
Phoenix flew to a height of 21,437 feet, or just over four miles, and reached a speed of Mach 1, the speed of sound. The 13-foot long rocket weighed 120 pounds fully loaded.
Twenty-four students traveled to the Friends of Amateur Rocketry launch site, located north of Edwards Air Force Base in California. In addition to Phoenix, the team brought Phantom, a solid rocket. Solid rockets function more like fireworks, while liquid rockets require a mix of a liquid fuel and an oxidizer, lit by a small solid motor. The liquids must be mixed in the right ratio at the right time to create the thrust that powers the rocket.
“They’re much more hands-on when it comes to launching, as we have to do a lot more than just hit a button that lights the motor,” says Natalie Ridenhour, chief executive officer of the team for 2024-25. “Many different pieces and systems go into getting a liquid rocket off the ground.”
While most other teams have opportunities to test their complete designs throughout the year, the Rocket Design Team has to travel to places like the Friends of Amateur Rocketry site to safely launch their full projects. Individual components like motors can be tested on their own, but seeing how everything works together requires a full-scale launch.
While preparing for Phoenix’s launch, the team discovered a faulty valve that had to be replaced. The liquid nitrous oxide leaking out of the valve was so cold that ice was forming on it, even in 100-degree heat. While Phoenix launched successfully, the solid rocket Phantom wasn’t so lucky. Its motor over-pressurized, causing the rocket to suffer a catastrophe at takeoff.
“If there’s one thing I’ve learned in my time on this team, it’s that if something can go wrong at the launch site, it will,” says Ridenhour. “By bringing team members out to launches we’re able to pass on problem-solving skills to future team leaders.”

About design teams
Design teams are registered student organizations that operate as 501(c) non-profit businesses. The teams work like small start-up companies, bringing together students from different disciplines to work on large-scale projects. In addition to hands-on design and manufacturing experience, students gain experience in project management, fundraising, public relations and more. For more information, visit design.mst.edu.
