You Might Be an O’Neillian and Not Even Know It

Part of the role of the Space Frontier Foundation is to find ways to connect the promise and potential of space to people who are not already in the space industry. That means helping bridge the language, assumptions, and motivations that often shape how we talk about space — and how we act on it.
One useful tool for doing that is to offer frameworks that break down the complexity of “space” into more understandable parts. Yes, I know — “framework” is a word that smells like business school, and I did in fact dive deep in that scent during my MBA days. But sometimes, a little oversimplification can be incredibly useful. It gives us a common language, a shared starting point. And from there, we can get into nuance, debate, and collaboration.
Over the next series of articles, I’ll share a few of the frameworks that have helped me make sense of the space community — some borrowed, some adapted, some homegrown. These aren’t gospel. They’re not scientifically rigorous. But they are tools. Tools to spark conversation, to illuminate assumptions, and maybe to make the space world a little more welcoming to those outside of it.
Let’s start with one of the earliest and most enduring rubrics I came across — one that originated with our very own Rick Tumlinson, one of the co-founders of the Space Frontier Foundation.
Rick proposed that there are three archetypal visions of why we go to space. He used three iconic figures to represent them — not because those individuals were pure ideologues, but because they offer an easy shorthand.
The Von Braunians
Named for Wernher von Braun, the German-born rocket engineer who played a central role in launching the American space program. The Von Braunian perspective sees space as a domain of national purpose. This is the arena of prestige, of geopolitical competition, of state-led feats. The moon landing wasn’t just about science or dreams — it was about demonstrating American might in a Cold War context. This frame tends to emphasize central coordination, high engineering standards, and long timelines.
The Saganites
Inspired by Carl Sagan, the beloved astronomer and science communicator who reminded us that “we are made of star stuff.” Saganites see space as a canvas for scientific discovery and philosophical reflection. The value of space lies in what it teaches us — about the universe, about life, and about ourselves. It’s a domain of wonder, of shared human curiosity, and of global collaboration for knowledge’s sake.
The O’Neillians
Carrying the flame of Gerard K. O’Neill, author of The High Frontier, this camp believes that space is not just for governments or science — it’s for people. O’Neillians envision space as a place for human settlement, commerce, and expansion. They talk about orbiting habitats, space-based solar power, asteroid mining. It’s a fundamentally optimistic vision: space as a frontier to build a better world (or worlds), not just to study or secure.
Of course, these are simplifications. They overlap. Real people and organizations often borrow from more than one of these worldviews. But it’s not hard to see how this trio of motivations — national prestige, scientific discovery, and human expansion — continue to shape today’s space conversations.
This framework, first offered decades ago, still resonates. It has helped me better understand the different — and sometimes competing — narratives that swirl around space. And I hope it can do the same for you.
In the coming weeks, we’ll go beyond this triad to explore other ways of mapping the interests, assumptions, and tensions in the space ecosystem — from sustainability and security to economics and ethics.
Because the more we understand why we go to space, the better we’ll be at deciding how we go — and how we build the future.
