This week on Pathfinder, we’re kicking off a special three-part series on lunar architecture, brought to you by our friends at Lockheed Martin. To kick off the series, we’re exploring the future of lunar architecture more broadly with Rob Chambers, Director of Strategy for Human Space Exploration at Lockheed Martin, and Alex MacDonald, Chief Economist at NASA.

In this episode, Alex and Rob share their perspectives on the complexities of building sustainable lunar missions and the critical technologies shaping the future. The discussion dives into the integration of international collaboration, public-private partnerships, and groundbreaking innovations that will enable humanity’s return to the Moon and its next steps across the solar system.

We also cover:

NASA’s Artemis program and the Moon-to-Mars exploration strategy
The role of international and commercial partnerships in advancing lunar missions
Foundational infrastructure, including habitats, rovers, and nuclear power systems
Lessons from Apollo and how they inform today’s approach to sustainable lunar exploration
The evolving lunar economy and what it might mean for humanity’s future in space

And much, much more...
