On Tuesday, December 10, the members of the topical team (FRISSBE-ZAG, University of Bremen, Sorbonne Université, RWTH Aachen University, Ghent University, New York University, École Centrale Lille, and the Center of Applied Space and Technology and Microgravity), sponsored by ESA, met at the Zamansky tower (Sorbonne Université) to discuss the work on creating a new multi-diagnostic facility, which will enhance our understanding on the flammability of fire-retarded materials in microgravity and partial gravity environments, it will improve the fire safety for longer space missions. The vast and dilated expertise of the members is key to unfolding and addressing the key challenges for fire safety on spacecraft. A big thanks to the European Space Agency for supporting the topical team and to the national agencies of the respective countries for their respective support (German Space Agency - DLR, Centre National d'Estudes Spatiales - CNES, Slovenian Space Office, and the Belgian Institute for Space Aeronomy BELSPO).
