Magnetospheric considerations for solar system ice state [PDF]

, 2018
The current lattice configuration of the water ice on the surfaces of the inner satellites of Jupiter and Saturn is likely shaped by many factors. But laboratory experiments have found that energetic proton irradiation can cause a transition in the ...

Spatial Scales of Electron Density Fluctuations in the Martian Ionosphere

The Astrophysical Journal
In recent Martian ionospheric studies, the spatial scales of electron density irregularities have been computed using magnetic field measurements by treating these fluctuations as electromagnetic.

UVMag: stellar formation, evolution, structure and environment with space UV and visible spectropolarimetry

, 2014
Important insights into the formation, structure, evolution and environment of all types of stars can be obtained through the measurement of their winds and possible magnetospheres.

The Colocation of Magnetic Reconnection and Current Disruption in Jovian Middle Magnetosphere

The Astrophysical Journal Letters
Magnetic reconnection and current disruption are two key processes in driving energy conversion and dissipation in planetary magnetospheres. At the Earth, the two processes usually occur at different locations: the current disruption process occurs more ...

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

The Incompressible Magnetohydrodynamic Energy Cascade Rate Upstream of Mars: Effects of the Total Energy and the Cross-helicity on Solar Wind Turbulence

The Astrophysical Journal
Solar wind turbulence is a dynamical phenomenon that evolves with heliocentric distance. Orbiting Mars since 2014 September, Mars Atmosphere and Volatile EvolutioN offers a unique opportunity to explore some of its main properties beyond ∼1.38 au.

Perspective on Energetic and Thermal Atmospheric Photoelectrons

Frontiers in Astronomy and Space Sciences, 2021
Atmospheric photoelectrons are central to the production of planetary ionospheres. They are created by photoionization of the neutral planetary atmosphere by solar EUV and soft X-ray irradiance.

Breaking Down the Wall That Historically Separates the Atmosphere, Ionosphere, and Magnetosphere (AIM) Communities: AGU Chapman Conference on AIM Coupling

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract This meeting report summarizes outcomes from the AGU Chapman Conference on Particle Precipitation: Drivers, Properties, and Impacts on Atmosphere, Ionosphere, Magnetosphere (AIM) Coupling, held 14–21 February 2025, in Melbourne, Australia. This conference brought together scientists from around the world to identify pressing AIM open science ...

Observations of a Mini‐Magnetosphere Above the Martian Crustal Magnetic Fields

Geophysical Research Letters, 2023
Mars is typically regarded as a non‐magnetic planet. Currents in the Martian ionosphere generate a Venus‐like induced magnetosphere which deflects the solar wind flows and piles up the interplanetary magnetic fields.

Fast magnetic reconnection via jets and current microsheets [PDF]

, 2003
Numerical simulations of highly nonlinear magnetic reconnection provide evidence of ultrathin current microsheets. These small-scale sheets are formed by strong exhaust jets from a primary large-scale current layer.
