The Space Security, Safety, and Sustainability (SSSS) Program at The University of Texas at Austin’s (UT) Strauss Center for International Security and Law and the Cockrell School of Engineering, in partnership with the International Academy of Astronautics (IAA), MITRE (video), and NorthStar Earth and Space (video), will hold the 11th annual Space Traffic Management conference, “STM: From the Ground Up and Back” on March 4-5, 2025. Additional support is provided by The Aerospace Corporation (video available), Aerospace Policy Solutions, LLC, and Kayhan Space.
Experts from all over the world gathered to discuss and exchange knowledge on Space Traffic Management. Technical sessions will be devoted to several key topics including the environment, economy and operations, and ecosystems.
Venue
The 2025 conference will be held at The University of Texas at Austin, Texas USA.

Call for Papers
We invite interdisciplinary researchers, industry experts, and policymakers to submit papers for our upcoming conference focused on Space Traffic Management (STM): From the Ground Up & Back. As the title suggests, STM includes safe access into outer space, operations within, and the safe return to Earth. This conference seeks to address critical issues in three thematic areas:
Environment: Explore innovative solutions and policies on Recycling, Removal, and Reentry; assess the risks and impacts of Space Debris and Congestion; analyze Externalities from Space Traffic; and examine Orbital Capacity and its associated policies.
Economy: Discuss advancements and challenges in Launch and Reentry operations; delve into the emerging fields of In-Space Servicing, Assembly, and Manufacturing, including Rendezvous and Proximity Operations; evaluate the role of Commercial Space Situational Awareness (SSA) and Space Traffic Coordination; and explore the concept of a Circular Space Economy.
Ecosystems: Investigate the interactions between Systems and Infrastructures, with a focus on Spaceports, Information Infrastructure, Cybersecurity, and Cislunar/Deep Space activities.
We welcome papers that present new, forward-thinking perspectives on these topics. Please submit your abstracts and join us in shaping the future of space traffic management.

Space Traffic Management, September 2005, Paris, France, 104 pages. At first glance, the management of space traffic does not appear to be a pressing problem. On closer examination, this judgement has to be challenged. A high level and ever growing number of launches from more and more launch sites and spaceports, the participation of non-governmental entities, the positioning of satellite constellations, an increase in space debris and the advent of reusable launch vehicles support this view. Conceptualizing space traffic management will turn out to become a relevant task during the next two decades. Space traffic management however, will limit the freedom of use of outer space. Therefore an international consensus on internationally binding regulations will only be achieved, if States identify certain urgency and expect a specific as well as collective benefit – including an economic benefit – from this. The study addresses or directs decision makers in UNCOPUOS, ITU and ICAO to approach specific problems, organizations which are building blocks for a future space traffic management regime.
Space Traffic Management – Towards a Roadmap for Implementation, Published in June 2018, 156 pages. This study revisits the topic of Space Traffic Management (STM) with the purpose of providing an updated inter-disciplinary context and of supporting decision-making in the global community. In 2006, the International Academy of Astronautics (IAA) took on the task of conducting a first study on STM (the “Cosmic Study”), then kick-starting a process of discussion of STM as a means to effectively deal with the increasing challenges space actors face. More than a decade later, this new study draws from the extensive academic work and policy-making activities carried out since the “Cosmic Study”. Its purpose is to revisit and adjust the concept of STM to current advancements in space activities as well as to geopolitical developments. In addition to presenting a more coherent and robust concept of STM, the study discusses the potential of STM to influence or shape the evolution of the legal and regulatory framework for space activities.
