Thermal conductivity as a function of porosity for different meteorite samples. For reference, the models proposed by Flynn et al. (2018) and Krause et al. (2011) are also shown. Thermal conductivity of the MASCOT rock was estimated based on the analysis of Hamm et al. (2022). Thermal inertia and thermal conductivity relate to each other following Eq. 1. The porosity and thermal conductivity for the Ryugu samples (Nakamura et al. 2022) is indicated
