Spatial and Temporal Extent of Plasma Depletion Events in the Ionosphere of Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has detected as many as 1,125 plasma depletion events (PDEs) in the Martian ionosphere from October 2014 to May 2021. PDEs, characterized by significantly reduced plasma density, elevated electron temperatures, and increased electrostatic fluctuations, remain poorly understood in ...

An Inversion of Magnetic Field Measurements to Constrain the Depth, Thickness, and Conductivity of Europa's Ocean

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Galilean satellite Europa is a primary candidate for the study of ocean worlds. In anticipation of NASA's Europa Clipper and ESA's JUICE missions, we revisit the magnetic field measurements of the Galileo spacecraft. The ocean's induction response is governed by its induction amplitude and phase shift, which are a function of the ocean ...

Measurements of Forbush Decrease Events at the Center of the South Atlantic Magnetic Anomaly With Muon Detectors

Space Weather, Volume 23, Issue 10, October 2025.
Abstract We present the construction and validation of a low‐cost muon detector in Paraguay, located at the center of the South Atlantic Magnetic Anomaly (SAMA), where the geomagnetic cutoff rigidity R $R$ is 9.63 GV. The detector consists of plastic scintillator plates coupled with silicon photomultipliers for light detection.

Multi‐MeV Electron Occurrence and Lifetimes in the Outer Radiation Belt and Slot Region During the Maximum of Solar Cycle 22

Space Weather, Volume 23, Issue 10, October 2025.
Abstract The Combined Release and Radiation Effects Satellite (CRRES) observed the response of the Van Allen radiation belts to peak solar activity within solar cycle 22. This study analyses relativistic and ultra‐relativistic electron occurrence and loss timescales within the CRRES High Energy Electron Fluxometer (HEEF) data set, including during ...

Thermospheric Density Disturbances During the 2015 St. Patrick's Day Geomagnetic Storm: Model–Observation Comparisons and Analysis of Intense Polar Density Spikes

Space Weather, Volume 23, Issue 10, October 2025.
Abstract Drag affecting satellites in low Earth orbit varies significantly during geomagnetic storms due to changes in thermospheric density. While neutral density can be inferred from satellite measurements, such data sets are limited and restrict neutral density/orbit prediction capabilities.
