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 ...

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 ...

Sensitivity of the Martian Magnetotail to Model Configuration Choices in Multispecies MHD Simulations

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Numerical modeling has been a key component in the study of the Mars space environment, providing a comprehensive global representation that is not always easy to obtain in spacecraft measurements. However, there are inconsistencies in data‐model and model‐model comparisons, regardless of whether the simulation conditions are identical or ...

Extraction of polar and nonpolar biomarkers from the martian soil using aqueous surfactant solutions [PDF]

, 2012
The Life Marker Chip intends to use an aqueous surfactant solution to extract both polar AND nonpolar biomarkers from the martian soil for transport to an antibody-based detection system. Currently, a solution of 1.5 g l-1 polysorbate 80 in 20:80 (vol:

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.

Impacts of the GDS 2018 Global Dust Storm on Martian Ionosphere‐Thermosphere Coupling via Atmospheric Tides

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract In this study, we investigate the ionospheric and thermospheric responses to the 2018 Mars global dust storm (GDS 2018) by examining atmosphere–ionosphere coupling through tidal structures. Using Mars Atmosphere and Volatile EvolutioN Neutral Gas and Ion Mass Spectrometer observations, we analyze tidal amplitudes, phases, and inter‐species ...

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 ...

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 ...

Mars' O+ ${\mathbf{O}}^{+}$ and O2+ ${\mathbf{O}}_{\mathbf{2}}^{+}$ Ion Escape During Disappearing Solar Wind Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Disappearing solar wind events (DSWEs), intervals when the solar wind proton density <1 cm−3 ${\text{cm}}^{-3}$, represent one extreme of the Mars solar wind interaction. Using data from NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission from February 2016 to May 2024, 154 orbits across 90 unique days were identified.
