Development of a Small-Sized Line Heat Source Apparatus for the Thermal Conductivity Measurement of Extraterrestrial Soils

Naoya Sakatani Satoshi Tanaka Sota Arakawa

INTERNATIONAL JOURNAL OF THERMOPHYSICS 43(6) 2022年6月

The thermal conductivity of planetary soils, or regolith, is essential for understanding the present global thermal state of bodies. The thermal conductivity of lunar soils is important with respect to lunar crustal heat flow. Although in situ mea...

Tsuda

Nature Astronomy 5(8) 766-774 2021年8月

Planetesimals—the initial stage of the planetary formation process—are considered to be initially very porous aggregates of dusts1,2, and subsequent thermal and compaction processes reduce their porosity3. The Hayabusa2 spacecraft found that bould...

Thermal conductivity of lunar regolith simulant JSC-1A under vacuum

Naoya Sakatani Kazunori Ogawa Masahiko Arakawa Satoshi Tanaka

ICARUS 309 13-24 2018年7月

Many air-less planetary bodies, including the Moon, asteroids, and comets, are covered by regolith. The thermal conductivity of the regolith is an essential parameter controlling the surface temperature variation. A thermal conductivity model appl...

Thermal conductivity model for powdered materials under vacuum based on experimental studies

N. Sakatani K. Ogawa Y. Iijima M. Arakawa R. Honda S. Tanaka

AIP Advances 7(1) 2017年1月

The thermal conductivity of powdered media is characteristically very low in vacuum, and is effectively dependent on many parameters of their constituent particles and packing structure. Understanding of the heat transfer mechanism within powder l...

Compressional stress effect on thermal conductivity of powdered materials: Measurements and their implication to lunar regolith

Naoya Sakatani Kazunori Ogawa Yu-ichi Iijima Masahiko Arakawa Satoshi Tanaka

ICARUS 267 1-11 2016年3月

Thermal conductivity of powdered materials under vacuum conditions is a valuable physical parameter in the context of planetary sciences. We report results of thermal conductivity measurements of 90-106 mu m and 710-1000 mu m glass beads, and luna...

This paper summarizes the evidence for the optical effects of space weathering, as well as the properties of the surface that control optical changes, on asteroid (101955) Bennu. First, we set the stage by briefly reviewing what was known about sp...
