Engineering student is using innovation and lessons learned from his OPG internship to build high-powered hobby rockets in his spare time.

With five rockets and a milestone certification under his belt, the Mechanical Engineering student is reaching for the stars through his unique hobby.

He credits much of his success to the support he’s received from his OPG mentors.


A job at OPG can give you the skills to reach for the stars—literally. Need proof? Meet Gabriel Joson, who is not your average engineering student.

During the day, the Professional Engineering Year intern works in OPG’s Simulator Services department, splitting his time between the Pickering Nuclear and Darlington Nuclear information centres.

But during his off time, he puts his OPG experience to use by building and launching powerful hobby rockets capable of soaring higher than commercial aircraft.

At the heart of Joson’s story is a dedication to innovation. By leveraging the skills and knowledge gained at OPG, the bright student is pushing the boundaries of what is possible.

He credits much of his success to the support he’s received from his OPG mentors in his department, especially the control technicians who have offered invaluable guidance on electronics, flight computers, and shop safety.

“Growing up, I always saw my classmates with cool talents and hobbies, but I never felt I had anything special,” said Joson, who is heading into his fourth year of Mechanical Engineering at Ontario Tech University. “That changed when I found rocketry in my second year.”

While attending his university’s rocketry team info night, he won his first rocket kit in a trivia game, igniting his new-found passion.

With his background in thermal fluids and love for hands-on engineering, it was only natural that he would take so quickly to the world of jet propulsion and aerodynamics.

So far, Joson has built five high-powered rockets, with three already flown, and recently achieved his Level 3 Certification with the Tripoli Rocketry Association, the highest level Tripoli members can achieve. It’s a milestone that allows him to fly engines powerful enough to cross into space, pending approvals.

OPG intern Gabriel Joson is an engineering student with a unique passion—building and launching high-powered hobby rockets.

Embrace challenge because once you conquer whatever hard things it throws at you, you won't be afraid to face anything anymore.

“Certification enables rocketeers to purchase more powerful rocket engines, demonstrating knowledge in aerospace and ensuring safety while having fun,” he explained.

Looking ahead, Joson’s ambitions continue to reach new heights, with his sights set on building a two-stage rocket capable of punching through 40,000 feet.

His advice to fellow students and aspiring engineers and rocketeers is simple:

“Embrace challenge because once you conquer whatever hard things it throws at you, you won't be afraid to face anything anymore.”
