Transport of Water in a Transient, Impact‐Generated Atmosphere on Mercury

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Mercury's polar cold traps host water ice deposits that are likely populated with impact‐delivered water via Mercury's exosphere. However, Mercury's near‐sun location experiences an extremely high photodestruction rate that rapidly destroys water with a timescale of only ∼3.5 hr.

Angular Momentum Balance of Superrotation in Venus's Middle and Upper Atmosphere Simulated by AFES‐Venus

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Based on simulations of the Venusian atmosphere using the AFES‐Venus GCM, we investigated the angular momentum (AM) balance that maintains the atmospheric superrotation (SR) at 35–90 km altitudes. In and above the cloud layer, the Eulerian‐mean meridional circulation consists of Hadley‐like cells at low latitudes and Ferrel‐like cells at ...

Impact Plasma Amplification of the Ancient Mercury Magnetic Field

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
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 ...

Energy Conservation in Flat FRW Cosmology

open access: yes, 2009
The consequence of energy conservation in the flat Friedmannn-Robertson-Walker (FRW) cosmology is a strictly positive accelerating expansion. A mechanism is proposed for this expansion due to the effect of the attractive (negative) gravitational potential of matter as it is being included within the expanding horizon, and the offsetting work of metric ...

Characterization of Mass Wasting Events on Lunar Maria Using Mini‐RF Radar Observations

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
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 ...
