John Jabbusch was, above all else, a lifelong student of the world. He had an endless curiosity and a deep love of learning that shaped nearly every part of his life. Books, science, and discovery were constant companions, and John was rarely far from a new idea to explore or a topic to investigate.
During his career in Naval intelligence, John developed a lasting fascination with spy stories, technology, and the mechanics of how things work. That same curiosity carried over into his professional life when he founded Carolina Advanced Digital, Inc., the technology and cybersecurity company he grew and successfully ran for over 40 years. Colleagues knew him as someone who could solve complex problems, think creatively, and approach challenges with both intelligence and humor.
His home reflected that same spirit of curiosity—complete with three still-operational oscilloscopes, a slide rule, and very likely a working abacus. John loved understanding how things worked and pursued hobbies simply for the joy of learning, from circuit design to home brewing, skiing to scuba diving.
John was also known for his sharp sense of humor. He loved Mystery Science Theater 3000, NASA missions, Halloween, and anything that blended science with imagination and fun. Friends and family remember him as someone who approached life with curiosity, wit, and an enthusiasm for discovery that never faded.
Sending John on a Celestis memorial spaceflight feels especially fitting for someone who spent a lifetime fascinated by science and the vast universe beyond us. As his journey continues among the stars, the curiosity and joy he shared with others remain part of his lasting legacy.
