The World Affairs Council of Atlanta recently welcomed Dr. Thomas Gonzalez Roberts, Assistant Professor at Georgia Tech’s Sam Nunn School of International Affairs and Daniel Guggenheim School of Aerospace Engineering, for a fascinating discussion on how space has evolved from a frontier of exploration into a domain shaped by geopolitics, security concerns, and international governance.

Speaking during World Space Week, Dr. Gonzalez Roberts highlighted Georgia Tech’s unique position as a global leader in both aerospace engineering and space policy. As founder of the Engineering Space Policy Lab (ESPL), his work focuses on three interconnected challenges: coordination, sustainability, and security in space.

A Crowded and Competitive Space Environment

While space may seem vast and limitless, the most valuable orbital pathways and radio frequencies are finite resources. With tens of thousands of satellites currently in orbit and launch costs continuing to fall, competition for access to these resources is intensifying.

Dr. Gonzalez Roberts described today’s near-Earth space environment as a tangled web of orbital trajectories, likening it to an orange wrapped in layers of yarn. The growing number of satellites, coupled with increasing amounts of space debris, raises important questions about how humanity can sustainably manage this shared environment.

Rules Written for a Different Era

A major theme of the discussion was the challenge of governing modern space activities using treaties largely written during the Cold War. The foundational 1967 Outer Space Treaty established principles that remain in force today, including freedom of exploration, a prohibition on national claims of sovereignty in space, and restrictions on placing weapons of mass destruction in orbit.

However, many of these agreements were negotiated before GPS, commercial satellite mega-constellations, and private spaceflight companies existed. As technology advances, policymakers increasingly face the challenge of adapting decades-old frameworks to a rapidly changing space economy.

The conversation also examined the growing role of space in national security. Satellites now support critical military functions including communications, reconnaissance, navigation, missile warning, and intelligence gathering.

Dr. Gonzalez Roberts discussed the creation of the U.S. Space Force and the broader reality that, while space is often described as a peaceful domain, space-based assets have long supported military operations on Earth. As nations become more dependent on satellites, these systems have become both strategic assets and potential vulnerabilities.

Visualizing the “Golden Dome”

One of the evening’s most compelling moments came when Dr. Gonzalez Roberts demonstrated research from Georgia Tech examining the proposed “Golden Dome” missile defense initiative.

Using advanced visualization models, his team explored what a space-based missile defense network might require. The findings illustrated the enormous scale of such an undertaking. Depending on the threat being defended against, hundreds or even thousands of satellites could be required to ensure constant coverage.

The models also highlighted a key geopolitical challenge: defensive systems can be perceived differently by other nations. A satellite designed to intercept missiles could also be viewed as a potential offensive weapon, raising concerns about strategic stability and the risk of escalating tensions.

Looking Ahead

As humanity launches more satellites, returns to the Moon, and contemplates missions to Mars, the questions raised during this discussion will only become more important. The future of space will be shaped not only by technological breakthroughs, but also by our ability to cooperate, communicate, and govern responsibly beyond Earth.

The evening provided attendees with a powerful reminder that the new space race is about far more than exploration. It is also about policy, security, sustainability, and the choices nations make today that will define the future of space for generations to come.
