Student-built rocket flies into the stratosphere

Go for launch!��

The 12-foot-tall rocket roared off the pad, streaming higher and higher until it was barely more than a pinprick in the morning sky.��

At 9:15 a.m. on Sunday, October 12, the ��ɫ��Ƶ successfully launched a rocket to 90,000 ft. in altitude.��

Designed and built by students in the club, the Mamba III rocket was a multiyear effort for SRL.

“Over 100 students worked on this project,” said Robert Umali, the team solids/composites lead and an aerospace sophomore. “Our test fire in March performed flawlessly. This rocket is built like a tank.”

Built From Scratch

Although off-the-shelf rocket plans are available online, the team elected to design theirs from the ground up, said Tyler Boim, team co-captain and an aerospace senior.

“Anything that we can make in-house we do. We fully made our avionics, composites, structures, and propellant. You understand each part and why it’s there. We’re not building Legos. You become a better engineer,” Boim said.

Putting the extra work into an independent design has also had career benefits for members like Nick Kieft, fellow team co-captain and an aerospace senior.��

“It’s experience for industry. In internship interviews, most of what I talk about with companies is the team. I manufactured this, designed that, tested this,” Kieft said.��

The successful launch in was a moment of exhilaration for all the team members, but only one portion of the day’s excitement, as the rocket body also contained sensors and cameras to track the flight and its landing.

Hitting Mach 3.36

“Mamba had a maximum Mach number of 3.36, equivalent to a velocity of 2,393 mph. Consistent communication of the rocket's flight computers throughout ascent and descent enabled us to determine a landing position and recover the vehicle. The final GPS coordinates were within 50 feet of the landing location,” Kieft said.��

Getting to the finish line was not always easy. The team experienced significant setbacks in launches on the previous Mamba I, which suffered a nose cone failure, as well as Mamba II, which exploded midflight.

“Mamba III used the same principles of the original design, but was reworked to account for lessons learned. We spent an entire year recharacterizing the propellant. We overbuilt this rocket to guarantee there would be no failures,” Boim said.

Next Steps

With the successful launch, the team is moving on to a much bigger goal called Spaceshot. They are beginning work on a new rocket design that can reach at least 350,000 ft. in altitude and become only the second student rocketry organization in the world to cross the atmospheric boundary into space – internationally designated at 328,000 ft.

“There will be big infrastructure improvements. We’ll be developing it over the next year or two,” Boim said.��

Although that launch will be after senior team members like Boim and Kieft graduate in May 2026, each team stands on the shoulders of earlier graduates, incorporating their design and education in the next iteration.

“I won’t necessarily be here for that launch, but a lot of the work you do leading up to it is just as valuable and rewarding,” Kieft said. “There’s smaller milestones along the way. SRL takes all the important first principles we learn in class to the next level.”
