Abstract Several national space agencies and commercial entities are currently targeting the Moon's south polar region for human and robotic exploration. Of particular interest are materials excavated and ejected from the Moon's largest and oldest impact structure, the South Pole‐Aitken Basin (SPA), as these ancient materials are a window into the ...

Impact Plasma Amplification of the Ancient Mercury Magnetic Field
Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

Abstract Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.

Characterization of Mass Wasting Events on Lunar Maria Using Mini‐RF Radar Observations
Abstract Evidence of mass wasting has been observed on the Moon since at least the Apollo era. Surface features indicative of mass wasting processes are traditionally characterized geomorphologically using visible images. In this study, we aim to better understand mass wasting features via their radar properties, which can provide insights into the ...

The OMEGA/Mars Express Dust Storm Catalog
Abstract This paper describes the OMEGA Dust Storm Catalogue (ODSC), built over almost 4 Martian Years (end of MY 26 to mid MY 30d) from OMEGA/Mars Express hyperspectral observations. A storm detection method has been developed based on a pixel clustering algorithm applied to the OMEGA dust optical depth retrievals made at 0.9 μ ${\upmu }$m.
