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]
Proc Natl Acad Sci U S APlanets 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 ...

Electrostatic Repulsion of Dust from Planetary Surfaces
The Planetary Science Journal, 2023 Surfaces of planetary bodies can have strong electric fields, subjecting conductive grains to repulsive electrostatic forces. This has been proposed as a mechanism to eject grains from the ground.

Exploring the solar system: the view of planetary surfaces with VIS/IR remote sensing methods
Proceedings of SPIE, 2011 The structure of planetary surfaces unveils basic formation processes and evolution lines of different objects in the solar system, and often the view on the top of a planet is the only available information about it. Advanced remote sensing technologies

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 ...

Main Results from the ISSI International Team “Characterization of 67P Cometary Activity”
Universe, 2023 The ESA/Rosetta mission accompanied the Jupiter Family Comet 67P/Churyumov-Gerasimenko and provided a huge amount of data which are providing important results about cometary activity mechanisms.

Planetary-Code-Collection: Thermal, Ice Evolution, and Exosphere Models for Planetary Surfaces
, 2022 PCC without MSIM: The major change is that MSIM (Mars Subsurface Ice Model) now has its own repository, and is no longer part of the Planetary-Code-Collection.
