We report the experimental study of aqueous foam wetting in microgravity. The liquid fraction ℓ along the bubble edges is measured and is found to be a relevant dynamical parameter during the capillary process. The penetration of the liquid in the foam, the foam inflation, and the rigidity loss are shown all to obey strict diffusion processes.
