One Earth, One Future: Building Cities in a Time of Reckoning

This week, as the crew of Artemis II spoke about their mission, what stood out was not only the scientific and technological milestone they represent, but the humanity they embodied. They described themselves not simply as astronauts, but as a crew that was carefully built, deeply collaborative, and bound by a shared purpose that transcends individual achievement. In their reflections, there was joy, humility, and an unmistakable sense of responsibility. As we watched their journey, their smiles and camaraderie were infectious and inspiring. Upon their return from the far side of the moon, they reminded us of something both simple and profound: that we are one people, sharing one planet, with a collective obligation to protect and sustain it.

It is a message that resonates far beyond space exploration. It speaks to the urgency of this moment here on Earth, where the contrast between what is possible and what is unfolding grows ever more stark. The Artemis II Crew did not speak about conquest or the dominance of any one country over another, or one people dominating another.

In recent months and years, we have witnessed a level of brutality that is painful to watch and difficult to comprehend. Conflicts continue to claim the lives of thousands of innocent people, as they generate profit and power for others. These are not distant tragedies; they reverberate through our cities, our institutions, and our shared moral landscape. They engender grief, and at times, a sense of helplessness, while exposing the entanglement of violence, inequality, and what can only be described as organized indifference.

Yet, if the Artemis II crew offers us anything, it is not an escape from these realities, but a reframing of them. Their message is not that we should look away from Earth, but that we should see it more clearly. From space, there are no borders, only a fragile, interconnected system that demands care, stewardship, and collective responsibility.

This is the spirit that has guided the work of the Great Cities Institute for the past thirty years.

At its core, the Institute has asked a deceptively simple question: What can cities and regions do to make themselves into great places? The answers, as our work has consistently shown, are neither easy nor singular. They require engaged research that bridges knowledge and action; partnerships that bring together communities, policymakers, and scholars; and a commitment to confronting the structural conditions that shape opportunity and constrain possibility.

Across three decades, we have worked alongside neighborhoods to advance commercial revitalization and quality-of-life planning, produced data-driven analyses on issues such as youth joblessness and economic restructuring, and supported policies that promote inclusive growth and workforce development. We have seen firsthand how disinvestment, segregation, and shifting economic systems produce deep inequities, but also how strategic, sustained engagement can begin to reshape outcomes.

In December, we marked our 30th anniversary, amidst a moment that calls for renewed clarity and purpose. The challenges facing cities are intensifying: housing affordability, climate vulnerability, economic displacement, and the erosion of public trust in institutions. At the same time, there is extraordinary capacity within communities to imagine and build alternatives and to insist on equity, to demand accountability, and to create new forms of collective life.

We invite you to check out our highlight videos and well as a video of the full celebration.

Our anniversary is not simply a moment of reflection; it is a point of departure, with the excitement of knowing that there is more to come.

We are also announcing the launch of our new website. Through the site, we aim to expand access to our research, deepen our collaborations, and more effectively share tools and insights that can support shaping our futures towards the common good. The platform reflects who we are: a hub for engaged scholarship, a partner in practice, and a space where ideas and action come together in service of the public good.

In a time marked by division and violence, the work of building great cities may seem both urgent and insufficient. But it is precisely in this tension that our role becomes most important. Cities are where inequalities are most visible and where the possibilities for transformation are most tangible. They are where we can choose, again and again, to align our systems with our values.

The Artemis II crew reminded us that we are capable of extraordinary coordination, ingenuity, and care when we act with shared purpose. The question before us is whether we can bring that same spirit to the work of sustaining life here on Earth.

At the Great Cities Institute, we believe the answer must be yes and that the work of building just, equitable, and life-sustaining cities is not only possible, but necessary now.
