David Zesinger joins Tom Spahr to discuss the "1492 moment" in space. From the moon's helium-3 resources to the contested nature of the domain, learn why space is the deciding factor in modern warfare.

David Zesinger is the first Space Force faculty member at the U.S. Army War Collegee, and he’s in the studio to discuss the vital role of space in national security. He joins host Tom Spahr to discuss the functions of the Space Force versus U.S. Space Command and how the strategic landscape is shifting towards a “1492 moment.” Zesinger explains how this new age of discovery is fueled by plummeting launch costs and the moon’s untapped resources, such as helium-3, which could provide thousands of years of clean energy. Space is no longer a sanctuary; it is a contested warfighting domain where adversaries like China and Russia are rapidly developing capabilities to target American assets. Zesinger emphasizes that building cross-service camaraderie and cooperation is essential to maintaining national security in this critical domain.

Space is a warfighting domain. We all understand that superficially, but maybe not deep down. Space is another venue for us to throw rocks at each other and for conflict and competition.
