Figure 2.

Thermal inertia map of InSight from predawn temperature data acquired by THEMIS (100 m spatial scale) between MY 30 and 32 during low‐dust seasons to minimize the atmospheric impact on the derived values that was created during landing site selection (Golombek et al., 2017). Note the limited range of thermal inertias across the site (145–185 J m⁻² K⁻¹ s^−1/2 or thermal inertia units, tiu), with a mean of ~164 J m⁻² K⁻¹ s^−1/2 within 1 km of the lander, indicating fairly homogeneous physical properties. The lander is located in a pixel with a thermal inertia of 166 J m⁻² K⁻¹ s^−1/2. Note higher thermal inertia associated with the rocky ejecta crater (REC).
