The Link Between Subsurface Rheology and Ejecta Mobility: The Case of Small New Impacts on Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract The dynamics of crater ejecta are sensitive to the material properties of the target, much like the crater size and morphology. We isolate and quantify the effect of target properties on the ejecta mobility (EM) ‐ the maximum radial extent of ejecta scaled by the crater radius.

Formation of Pancake Domes on Venus as Viscous Flows Over an Elastic Lithosphere

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract Venus' steep‐sided domes are circular volcanoes ∼10s of km wide and ∼1 km tall, which are known for their characteristic flat tops and steep sides. However, their composition remains mysterious. These “pancake” domes are likely formed by a high‐viscosity lava, and other studies have predicted a range of compositions, from rhyolite to basalt ...

Paleo‐Scours Within the Layered Sulfate‐Bearing Unit at Gale Crater, Mars: Evidence for Intense Wind Erosion

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract The surface of modern Mars is largely shaped by wind, but the influence of past wind activity is less well constrained. Sedimentary rocks exposed in the lower foothills of Aeolis Mons, the central mound within Gale crater, record a transition from predominantly lacustrine deposition in the Murray formation to aeolian deposition in the Mirador ...

Geomorphological Evidence of Near‐Surface Ice at Candidate Landing Sites in Northern Amazonis Planitia, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract This work presents geomorphological analyses of an area at the boundary between Arcadia Planitia and northern Amazonis Planitia, situated in the northern mid‐latitudes of Mars. Recent studies have indicated the presence of substantial volumes of near‐surface excess ice in Arcadia Planitia, making this region a promising candidate for future ...

A Map of Potential Topographic Anomalies on Venus

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract The most recent, highest‐resolution, global estimate of the topography of Venus is the Global Topographic Data Record (GTDR), a gridded representation of the altimetry data from the Magellan space mission. This product is impaired by an occasional pattern; a series of visually striking topographic “pits,” often referred to as spuriously low ...

Laser‐induced breakdown spectroscopy/laser ablation coupled to inductively coupled plasma mass spectrometry (LIBS/LA‐ICPMS) for the forensic screening and discrimination of lead‐free solders

Journal of Forensic Sciences, Volume 70, Issue 3, Page 980-994, May 2025.
Abstract The tandem LIBS/LA‐ICPMS technique is a desirable tool for the multi‐elemental determination, characterization, and classification of alloys as forensic evidence. In this study, LIBS/LA‐ICPMS is validated for the forensic evaluation of lead‐free solder alloys, which form valuable evidence from post‐blast crime scenes involving homemade and ...
