Lightning‐Induced Electron Precipitation Events Observed at Low Altitudes

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Lightning‐induced electron precipitation (LEP) events are important phenomena in the Earth's inner magnetosphere, where atmospheric lightning strokes cause energetic electron loss from the radiation belts. Lightning strokes generate electromagnetic waves that penetrate the ionosphere and propagate through the Earth's magnetosphere as so‐called

Modeling Jupiter's Dawnside Magnetodisc: Using Juno Observations to Constrain a Radial Force‐Balance Model

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract This study investigates Jupiter's dawnside magnetodisc, using plasma and magnetic field measurements from Juno orbits 5 to 12 to refine a radial force‐balance magnetodisc model. This iterative vector potential model examines variations in the azimuthal magnetodisc current, coupled with a magnetosphere‐ionosphere coupling model from which the ...

Identifying Landslides in Atla Regio on Venus

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract We performed a systematic search for landslides in the Alta Regio region of Venus, located from (16°S, 179°W) to (21°N, 147°W). Using data primarily from Magellan Cycle 1 radar imagery, we identified 29 landslides in this region. There were 19 previously identified across the entire surface (Malin, 1992, https://doi.org/10.1029/92je01343 ...

Quantities of Ballistically Hopping Water Molecules on the Moon: Consistent With Exospheric Hydration Observations

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Measurements of the lunar surface have revealed a variable presence of hydration, which has contributions from both hydroxyl (OH) and molecular water (H2O). Recent observations of the lunar hydration suggest that a component of this signature is comprised of molecules that are readily mobile and actively migrate across the lunar surface over ...
