My name is Dr. James Green, and over my 42-year career at NASA, I’ve had the incredible opportunity to explore the universe and unravel some of its greatest mysteries. I began my NASA journey in 1980 at the Marshall Space Flight Center, where I developed the Space Physics Analysis Network, a game-changing system that allowed scientists worldwide to analyze mission data in real time. This groundbreaking innovation laid the foundation for global collaboration in space research.
In 2006, I was appointed Director of NASA’s Planetary Science Division, and in 2018, I became NASA’s Chief Scientist, a role in which I helped define the agency’s scientific vision and priorities. I was privileged to lead and support historic missions such as New Horizons, which provided humanity’s first close-up images of Pluto, and the Juno spacecraft, which offered unprecedented insights into Jupiter’s magnetic field and atmospheric dynamics. Another career-defining moment was the successful landing of the Curiosity rover on Mars, as we searched for signs of habitability and evidence of life. One of the most captivating aspects of my work involved exploring icy moons like Europa and Enceladus, where we believe subsurface oceans could harbor life. “The question of whether we are alone in the universe is one of the most profound questions of all time,” I would often say, and it’s this quest that continues to inspire scientific exploration.
One of the most important lessons I learned at NASA was the value of studying human biology in space. Microgravity provides a unique environment where aging processes are dramatically accelerated. On Earth, changes like muscle loss, bone density reduction, and cellular stress occur gradually over decades, making them difficult to study in real-time. However, in the microgravity of space, these same processes unfold in a matter of weeks. This accelerated timeline gives us a rare opportunity to observe and understand the mechanisms of aging and cellular degeneration in ways that aren’t possible on Earth. “Studying aging in space gives us incredible insights into how cells adapt to extreme conditions,” I explain, because these insights can be crucial for developing new strategies to support healthy aging.
Research in space also reveals how cells and bodily systems respond to stress when traditional gravitational forces are removed. Understanding these responses helps us identify potential interventions that could slow down or even reverse aging-related damage. Partnering with the University of Oxford, IM8, and leading research teams, I’m now focused on applying these space science principles to create practical, science-backed solutions for cellular health. By leveraging data from microgravity studies, we can explore new approaches to longevity, targeting the root causes of aging and optimizing our formulations to support resilience and vitality.
When I retired from NASA, I wasn’t ready to stop making an impact. My career had given me a deep appreciation for how extreme environments, like those found in space, can teach us about the human body’s remarkable adaptability. Joining IM8 has allowed me to bring this wealth of knowledge to the field of health and wellness. At IM8, we are using the science of space to create products that promote cellular resilience, enhance autophagy (the body’s natural process of removing damaged cells), and optimize mitochondrial function to improve energy and vitality.
“The universe has always fascinated me, not just for its mysteries but for the lessons it offers about our own existence,” I say, and it’s this fascination that continues to drive my work. By understanding how cells adapt under stress, whether in space or here on Earth, we can develop nutritional strategies that support long-term health. Our goal at IM8 is simple but profound: to make cutting-edge science accessible and use it to empower people to age well and live better. By combining my experience as NASA’s Chief Scientist with ongoing research collaborations like those with the University of Oxford, we’re setting the stage for a new era of science-driven wellness.
Working with IM8 has given me a renewed sense of purpose. The work we’re doing is a direct extension of the scientific discoveries I was part of at NASA, and it feels incredibly rewarding to see how space research can transform everyday health. Our commitment to rigorous scientific validation, effective formulations, and long-term impact drives everything we do. We’re not just developing products; we’re advancing a new understanding of aging and cellular health.
The journey from exploring outer space to improving life on Earth is one of the most fulfilling chapters of my career. As we continue to innovate, I’m excited to see how space science can shape the future of wellness, helping people live longer and healthier lives. Our mission is ambitious, but I believe that by combining the best of space exploration with groundbreaking nutritional science, we’re paving the way for extraordinary health outcomes.
