An accurate estimation of the effective thermal conductivity of various insulation materials is
essential in the evaluation of heat leak and boil-off rate from liquid hydrogen storage tanks …

The physical properties of cometary nuclei observed today relate to their complex history
and help to constrain their formation and evolution. In this article, we review some of the …

INTRODUCTION The asteroid 162173 Ryugu is the target of the Japanese Hayabusa2
mission, which is designed to collect samples from Ryugu's surface and return them to Earth …

Establishing the abundance and physical properties of regolith and boulders on asteroids is
crucial for understanding the formation and degradation mechanisms at work on their …

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

C-type asteroids are among the most pristine objects in the Solar System, but little is known
about their interior structure and surface properties. Telescopic thermal infrared …

TIR, the thermal infrared imager on Hayabusa2, acquired high-resolution thermal images of
the asteroid 162173 Ryugu for one asteroid rotation period on August 1, 2018 to investigate …

Abstract Selective Laser Melting (SLM) or Laser Powder Bed Fusion (L-PBF) is the most
studied laser-based additive manufacturing process for metals and alloys. One important …

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

Measurements of the low‐temperature thermodynamic and physical properties of meteorites
provide fundamental data for the study and understanding of asteroids and other small …
