Optimization of the Mars ionospheric radio occultation retrieval

open access: yesEarth and Planetary Physics, 2018
Electron density is a key parameter to characterize Martian ionospheric structure and dynamics. Based on the ephemeris and auxiliary information derived from the Spacecraft, Planet, Instruments, C-matrix, and Events (SPICE) toolkit, we calculated the ...

Bidirectional Energy Transfer via Simultaneous Wave‐Particle Resonances in Inhomogeneous Space Plasmas

open access: yesAGU Advances, Volume 7, Issue 4, August 2026.
Abstract Wave‐particle resonance is a key mechanism for energy transfer in collisionless plasmas with important implications for wave excitation and particle acceleration. Cyclotron resonance occurs when a particle's gyromotion synchronizes with the wave fields, with their interactions usually describable by quasilinear diffusion or nonlinear trapping.

Martian Bow Shock and Magnetic Pile-Up Barrier Formation Due to the Exosphere Ion Mass-Loading [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2011
Bow shock, formed by the interaction between the solar wind and a planet, is generated in different patterns depending on the conditions of the planet.

Coupling Seismic, Gravity and Magnetic Surveys for the Investigation of Planetary Lava Tubes: A Terrestrial Analog Case Study in Lanzarote (Spain)

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Lava tubes are subsurface volcanic conduits formed during effusive basaltic eruptions and are considered key targets for planetary exploration. Orbital remote sensing on the Moon and Mars has identified numerous collapse pits interpreted as possible surface expressions of underlying lava tube systems. However, the limited resolution of current

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

open access: yesGeophysical 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.

Currents in the Martian Ionosphere: Cases Without Strong Crustal Magnetic Fields

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The Martian ionosphere hosts complex current systems driven both by solar wind interactions and neutral wind dynamo processes. While the global patterns of these current systems have been statistically examined, their detailed structures and orientations remain poorly constrained.

Variability of the Martian ionosphere

open access: yes, 2021
Historically, studying the Martian ionosphere has been difficult due to the lack of dedicated instruments for electron density measurements in the orbit of Mars.

Martian Magnetotail Neutral Sheet Asymmetry Driven by Heavy Planetary Pickup Ions

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract In the induced magnetotail of Mars, the neutral sheet is an important channel for atmospheric ion escape, yet the role of heavy planetary pickup ions in shaping its geometry has been unclear. Using three‐dimensional hybrid simulations, we demonstrate that these ions induce a global neutral sheet asymmetry via mass loading.

MAVEN Observations of Whistler-mode Waves Within the Magnetic Dips in the Martian Ionopause/Ionosphere

open access: yesThe Astronomical Journal, 2023
Whistler-mode waves are natural and common electromagnetic emissions observed both surrounding planets and their moons with and without intrinsic magnetic field.
