Some journeys into space begin simply – with a book, a curious question, or an unquenchable thirst for adventure. For Grant Bonin, founder of Gravity Lab, it was a bit of all three. Grant’s story illustrates that determination, curiosity, and networking can transform youthful fascination into groundbreaking innovations.

Grant grew up in Sault Ste. Marie, a scenic town in Northern Ontario. Initially aiming for bioastronautics at the University of Colorado Boulder, a friend’s casual challenge nudged him toward hands-on experience. He joined the Space Flight Laboratory at the University of Toronto, swapping mechanical engineering for electrical – because why stick with just one discipline?

His early career included fascinating stops at Four Frontiers, conceptualizing early Mars settlements, and Antarctic Broadband, improving satellite connectivity for remote researchers. These projects nurtured his multidisciplinary approach and prepared him for larger challenges ahead.

Today, Grant runs Gravity Lab, dedicated to solving one of space exploration’s biggest unknowns: how much gravity do humans need to thrive long-term? Rather than focusing only on how we get to Mars or the Moon, Grant’s team explores how humans can sustainably stay once we get there. Using small satellites equipped with extendable arms, Gravity Lab creates artificial gravity in space, essentially dialing gravity up and down like a thermostat – something crucial for future human space settlements.

As Grant explained, knowing precisely how humans adapt – or fail to adapt – to varying gravity levels is not just academic curiosity; it’s pivotal for humanity’s future. If people can’t healthily reproduce or sustain themselves below certain gravity thresholds, some destinations may be off the table or require new solutions entirely.

I asked Grant why more companies weren’t tackling this critical problem. His answer was refreshingly candid: the issue lies at a tricky intersection between scientific research and commercial viability. It requires investors willing to embrace a longer horizon for returns, something traditional venture capital isn’t always geared towards. Nevertheless, Grant remains optimistic about opportunities emerging as investment models evolve.

The conversation naturally shifted to the broader space industry. Grant sees it as an ecosystem ripe with uncertainty but brimming with opportunity. Companies like SpaceX have dramatically changed the landscape, but uncertainties about NASA’s direction and global economic factors make predictions tricky. Yet amidst uncertainty, Grant firmly believes opportunity thrives.

His passion for space is infectious, driven less by grandiosity and more by the joy of doing cool missions with cool people. Reflecting on what keeps him engaged, Grant stressed the importance of the right team and stimulating projects. Whether overcoming setbacks or celebrating breakthroughs, working alongside motivated, smart, and passionate colleagues has always been the highlight.

On inspiring the next generation, Grant stressed we must change the narrative. Space careers aren’t just about becoming astronauts or astrophysicists; they’re accessible to everyone. Whether in finance, marketing, manufacturing, or even soon-to-be “space janitors,” the industry offers countless avenues. Highlighting the human stories behind space advancements, rather than just the technical aspects, is crucial to attracting new talent.

Grant also openly discussed setbacks. He shared a personal story of initially dropping out of high school, reignited by a space exploration book that reshaped his trajectory. Throughout his career, he’s learned the value of transparency and trust, especially when leading teams through tough times. His candid reflections on the reality of entrepreneurship and leadership – complete with highs, lows, and learning moments – were particularly inspiring.

Reflecting on his proudest achievements, Grant’s time as Rocket Lab’s first employee and Chief Engineer for their space systems division stands out. Helping lay foundational stones for their success, including key hires and critical early missions, remains a significant source of pride.

His advice to those considering a space career is clear and encouraging: don’t limit yourself. Ask questions, seek mentors, network relentlessly, and never stop being curious. Above all, remember the space industry is vast, inclusive, and growing rapidly.

Grant’s journey from dreaming of Mars settlements to pioneering artificial gravity research reminds us that the space industry thrives on passionate, curious individuals ready to take on ambitious problems. So, if you’re wondering whether space might be your next frontier – Grant’s story is your sign to dive in.
