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.

Planetary Atmosphere and Surfaces Chamber (PASC): A Platform to Address Various Challenges in Astrobiology [PDF]
Challenges, 2014 The study of planetary environments of astrobiological interest has become a major challenge. Because of the obvious technical and economical limitations on in situ planetary exploration, laboratory simulations are one of the most feasible research ...

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 [PDF]
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.

Planetary-Code-Collection: Thermal, Ice Evolution, and Exosphere Models for Planetary Surfaces [PDF]
, 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.

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 ...
