The Space USB consortium was proud to take part in the International Astronautical Congress (IAC) 2025, held in Sydney, Australia, from 29 September to 3 October 2025. Two technical papers were presented during the conference, reflecting the project’s progress and contribution to the development of a standardized, interoperable interface for in-orbit servicing and modular spacecraft operations.

1. Design of an Interoperable Interface for In-Space Operations and Services of Modular Spacecraft

📅 Presented on 29 September 2025 by Dr. Mathieu Deremetz (Space Applications Services)
This presentation detailed the technical approach behind the Space USB interface, focusing on the design principles enabling interoperability among existing standards such as Hotdock, SIROM, and iSSI. It highlighted the system’s capacity to support data and power transfer, mechanical coupling, and misalignment tolerance—key enablers for future on-orbit servicing, assembly, and modular mission architectures.

2. Towards Sustainable Space Ecosystem: A State of the Art Survey on Standardizing Spacecraft Service Interfaces for Modular Orbital Systems

📅 Presented on 2 October 2025 by Mr. Raphaël Boissonnade (TASF) and Mr. Mehmed Yüksel (DFKI)
This paper provided a comprehensive overview of the state of the art in modular spacecraft interfaces, reviewing current developments in Europe and worldwide. The analysis positioned Space USB within the broader context of standardization efforts, underlining its contribution to building a sustainable, interoperable ecosystem for future space operations.

Both sessions attracted significant interest from the international space community, confirming the relevance of European cooperation in advancing open and modular approaches to spacecraft servicing.
