Thermodynamic Constraints on H2 Production and Habitability From Mg‐Rich Serpentinites as Mars Analogs

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Serpentinization produces hydrogen and methane through abiotic water‐rock interactions, potentially supporting chemotrophic life in planetary subsurface environments. Serpentine deposits in the Martian Noachian landscapes of Nili Fossae and the Southern Highlands have been considered as potential paleo‐habitable zones. However, the geochemical

Exomars entry and descent science [PDF]

, 2008
The entry, descent and landing of ExoMars offer a rare (once-per-mission) opportunity to perform in situ investigation of the martian environment over a wide altitude range.

Non‐Migrating Thermal Tides in the Martian Lower Atmosphere Observed by EMM/EMIRS

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Thermal tides significantly influence Martian atmospheric dynamics and radiative transfer. However, the excitation mechanisms of non‐migrating tides, exhibiting diverse spatial structures, remain poorly understood due to the limited number of observations.

An estimation of the mass dragged by the solar wind from Mars’s atmosphere in its geologic history [PDF]

Geofísica Internacional, 2001
In the past Mars had a denser atmosphere, but it lacks a magnetic field to protect the ionosphere and exosphere from the solar wind. A model for describing the loss of atmosphere in geologic time is presented.

Photovoltaic array for Martian surface power [PDF]

Missions to Mars will require electric power. A leading candidate for providing power is solar power produced by photovoltaic arrays. To design such a power system, detailed information on solar-radiation availability on the Martian surface is necessary.

Martian meso/micro-scale winds and surface energy budget [PDF]

, 2011
Regional, diurnal and seasonal variations of surface temperature are particularly large on Mars. This is mostly due to the Martian surface remaining close to radiative equilibrium.

High‐Latitude Zonal Jets in the Martian Upper Atmosphere Driven by Non‐Orographic Gravity Waves

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract We investigate thermosphere responses to non‐orographic gravity waves (GWs) using wind measurements from the Neutral Gas and Ion Mass Spectrometer onboard the Mars Atmosphere and Volatile EvolutioN mission, alongside simulations from the Mars Planetary Climate Model. We focus on zonal jets in high‐latitude regions of the upper atmosphere.

Seasonal Water "Pump" in the Atmosphere of Mars: Vertical Transport to the Thermosphere

, 2019
We present results of simulations with the Max Planck Institute general circulation model (MPI-MGCM) implementing a hydrological cycle scheme. The simulations reveal a seasonal water "pump" mechanism responsible for the upward transport of water vapor ...
