Untrackable distal ejecta on planetary surfaces [PDF]
Nature Communications, 2023 Heterogeneous shock impedances of planetary materials cause abrupt changes of ejection angles, forming non-radial ejecta. Interpretations for provenances of surface deposits and ages derived from crater counts are affected by such untrackable ejecta.

Decoding planetary surfaces by counting cracks [PDF]
Proceedings of the National Academy of Sciences of the United States of AmericaPlanets are often covered with thin cracked shells. From mud films to lithospheres of rock or ice, fracture networks form two-dimensional (2D) tessellations of convex polygons whose geometry encodes their genesis. Here, we chart the geometry of 2D fracture mosaics across the solar system, and decode their formative conditions using a new dynamical ...

The Planetary Science Journal, 2023 The surfaces of airless planetary bodies, such as the Moon or Mercury, are covered with regoliths, which interact with the solar wind. The solar protons can either be absorbed by the surface or neutralized and reflected as hydrogen energetic neutral ...

Thermal Studies of Planetary Surfaces [PDF]
Symposium - International Astronomical Union, 1981 Ground-based and spacecraft observations of planets, satellites, and asteroids in the thermal infrared have provided a wealth of information on planetary temperatures, dimensions, and surface properties. Internal heat sources have been revealed for Jupiter, Saturn, and Neptune, and active volcanism on Io has been discovered and monitored.

Optical Constants of Martian Dust Analogs at UV–Visible–Near-infrared Wavelengths
The Astrophysical Journal Supplement Series, 2023 We present an advanced light-scattering model to retrieve the optical constants of three Martian dust analogs: Johnson Space Center regolith simulant, Enhanced Mojave Mars Simulant, and Mars Global Simulant.
