Interplanetary Magnetic Field Effect on the Location of the Martian Bow Shock: MAVEN Observations

The Astrophysical Journal, 2023
The Martian bow shock (BS) is generated with the mass-loading and magnetic pileup processes when the solar wind interacts with the Martian ionosphere. In this vein, the interplanetary magnetic field (IMF) frozen in the solar wind can affect the location ...

Revealing the CME Impact on the Martian Nightside Ionosphere Based on MAVEN and Tianwen-1 Observations

The Astrophysical Journal
Due to the absence of an Earth-like dipole magnetic field, the impact of coronal mass ejections (CMEs) on the Martian nightside ionosphere differs from that on Earth and is still not well understood.

MoMo: a new empirical model of the Mars ionospheric total electron content based on Mars Express MARSIS data

Journal of Space Weather and Space Climate, 2019
Aims: Several scientific landers and rovers have reached the Martian surface since the 1970s. Communication between the asset (i.e., lander or rover) and Mars orbiters or Earth antennas uses radio signals in UHF to X-band frequencies passing through the ...

Martian Proton Aurora Brightening Reveals Atmospheric Ion Loss Intensifying

Geophysical Research Letters, 2023
The Martian proton aurora is a distinct aurora phenomenon resulting from the direct deposition of solar wind energy into Mars' dayside atmosphere. What solar wind parameters influence the aurora activity in the short term is yet unknown, as are the ...

How Large Are Marsquakes? Revisiting Magnitude Scaling and Implications for Marsquakes and Meteoroid Impacts

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Reliable estimates of seismic source size on Mars are critical for interpreting tectonic activity and impact processes, constraining the planet's interior evolution, and informing the design of future Martian seismic experiments. However, because InSight observations are limited to a single station, magnitude estimates cannot rely on empirical

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines. Although solar radio bursts have been studied since the 1940s, observations remain mainly restricted within 1 AU.

Sub-solar electron temperatures in the lower Martian ionosphere

Journal of Geophysical Research: Space Physics, 2019
Martian sub-solar electron temperatures obtained below 250 km are examined using data obtained by instruments on the Mars Atmosphere Evolution Mission (MAVEN) during the three sub-solar deep dip campaigns and a one-dimensional fluid model. This analysis was done because of the uncertainty in MAVEN low electron temperature observations at low altitudes ...

Electron Regulation of Proton Cyclotron Waves at Mars

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Proton cyclotron waves (PCWs), generated by the solar wind ionization and subsequent pickup of exospheric hydrogen, offer independent constraints on water loss from Mars. However, translating wave observations into quantitative escape rates has been hindered by an incomplete understanding of wave evolution, particularly the role of electron ...

Optimization of the Mars ionospheric radio occultation retrieval

Earth 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 ...

Retrieval of ionospheric profiles from the Mars Express MARSIS experiment data and comparison with radio occultation data [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2012
Since 2005 the Mars Advanced Radar and Ionospheric Sounding experiment (MARSIS) aboard Mars Express has acquired a unique dataset on the ionosphere of Mars made up of ionospheric soundings taken by the instrument working in its active ionospheric ...
