The flow of plasma in the solar terrestrial environment [PDF]
The overall goal of our NASA Theory Program was to study the coupling, time delays, and feedback mechanisms between the various regions of the solar-terrestrial system in a self-consistent, quantitative manner. To accomplish this goal, it will eventually

The Evolution of Hot Flow Anomalies in Martian Space Environment
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Hot Flow Anomalies (HFAs) are transient foreshock structures generated by solar wind discontinuity‐bow shock interactions, with their evolution only confirmed near Earth. Using MAVEN and Tianwen‐1 joint observations, we study the evolution of a Martian HFA event detected on 17 September 2022 (dayside by MAVEN, nightside by Tianwen‐1).

Continuation of data analysis from the ion mass spectrometer on the ISIS-2 spacecraft [PDF]
The spectrometer measures the composition and number density of the positive ion species in the ionosphere as well as the ion flux normal to the spacecraft trajectory. The measurement of high latitude ionospheric dynamics is reported.

Role of gravity waves in vertical coupling during sudden stratospheric warmings
, 2016 Gravity waves are primarily generated in the lower atmosphere, and can reach thermospheric heights in the course of their propagation. This paper reviews the recent progress in understanding the role of gravity waves in vertical coupling during sudden ...

Reconnection Preferentially Accelerates Light Ions at Ganymede's Magnetopause
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Juno's flyby of Ganymede revealed ion composition in its vicinity with the Jovian Auroral Distributions Experiment–Ion (JADE‐I) instrument. Throughout this flyby, we derive species‐resolved ion density and velocity moments by decomposing the time‐of‐flight data into contributions from individual ion species using species‐dependent fits. At the

On the Feasibility of Interhemispheric Patch Detection Using Ground-Based GNSS Measurements
Remote Sensing, 2018 Dual-frequency GNSS data processing is currently one of the most useful techniques for sounding the ionosphere. Hence, this work was aimed at the evaluation of ground-based GNSS data for the continuous monitoring of polar patches in both hemispheres.

Global Effects of Chorus and Hiss Waves on Trapped Energetic Electrons at Jupiter
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Unlike Earth, where whistler‐mode chorus is generally observed outside the plasmasphere and hiss is predominantly confined within it, Jupiter's magnetosphere frequently hosts both wave modes simultaneously. Using Juno observations, we present a global survey of whistler‐mode waves at Jupiter, demonstrating that both chorus and hiss are ...
