In this work, we model the surface temperatures of 16 Psyche. Our modeling is focused on capturing the diurnal and seasonal surface temperature variations caused by 16 Psyche&#8217;s large obliquity (95\u00b0) and moderately high eccentricity (0.134). Using a semianalytic framework, we predict that large thermal variations (including at the poles) can cause cracking of boulders leading to a porous surface regolith. This prediction is consistent with a high-porosity surface regolith inferred from thermal inertia measurements. We also find that water ice is not likely to be stable at any latitude.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Carver J. Bierson, Linda T. Elkins-Tanton and Joseph G.
