Thermal inertia and surface roughness are proxies for the physical characteristics of
planetary surfaces. Global maps of these two properties distinguish the boulder population …

Spacecraft missions have observed regolith blankets of unconsolidated subcentimetre
particles on stony asteroids,–. Telescopic data have suggested the presence of regolith …

Planetesimals—the initial stage of the planetary formation process—are considered to be
initially very porous aggregates of dusts,, and subsequent thermal and compaction …

This paper describes a new, analytic, and mechanistic model for calculating the effective
thermal conductivity (k eff) of planetary regolith, or any porous granular medium consisting of …

For the nuclear pebble bed of the high temperature gas-cooled reactor (HTGR), a tree-
based automated machine learning approach is developed to discuss the complicated …

Thermal infrared emission and thermophysical modeling techniques are powerful tools in
deciphering the surface properties of asteroids. The near-Earth asteroid (3200) Phaethon is …

The MMX infrared spectrometer (MIRS) is an imaging spectrometer onboard MMX JAXA
mission. MMX (Martian Moon eXploration) is scheduled to be launched in 2024 with sample …

Middle infrared spectral results obtained in‐situ by the Hayabusa2 MARA instrument are
generally in‐line with previous results and a new comparison with sample C0137 returned …

The thermal properties of a planet's regolith are of primary importance in solar system
exploration. Thermal conductivity and the related parameter thermal inertia are often used to …
