Martian Proton Albedo as Signature of Near‐Surface Water

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

Thermal Escape of Atomic Hydrogen on Mars: A Comprehensive View With a General Circulation Model

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Mars loses water mainly through the photodissociation of water vapor, followed by the thermal escape of light hydrogen atoms. Observations have revealed large seasonal variations in hydrogen concentration in the upper thermosphere, peaking during southern summers and intensifying during dust storms.

Power Spectral Characteristics of Martian Ionospheric Irregularities

The Astrophysical Journal
The intrinsic magnetic field of a planet plays a key role in its ionospheric dynamics. Mars lacks a global magnetic field, thus ionospheric plasma is weakly coupled to crustal and induced magnetic field.

Design for stray-light reduction to a Martian ionospheric imager

Applied Optics, 2020
We demonstrate a new design high-contrast optics suitable for use on a stray-light reduction. Two-dimensional distribution of diffracted light was numerically analyzed and confirmed by a laboratory measurement to determine its characteristics. Laboratory measurements confirm stray-light performance with ∼

Thermal Effects of Gravity Waves in Planetary Atmospheres

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Internal atmospheric acoustic‐gravity waves substantially drive the global dynamical, thermal, and compositional structure of planetary atmospheres. While the dynamical effects of acoustic‐gravity waves have been extensively studied, especially on Earth and Mars, their thermal effects are insufficiently explored in planetary atmospheres.

Electrostatic Solitary Waves in Electronegative Martian Plasma

The Astrophysical Journal
The solar wind interacts with planetary magnetospheres, generating plasma waves in both the upstream region and the magnetospheric environment. Mars, lacking an inherent magnetic field, has an induced magnetosphere formed through solar wind interaction ...

MARSIS Observations of the Martian Nightside Ionosphere During the September 2017 Solar Event

Geophysical Research Letters, 2018
We present topside ionospheric sounding on the nightside of Mars during the September 2017 solar event by Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) on board Mars Express along with complementary dayside observations from Mars ...

Planned observations of thermal plasma drifts and solar wind interactions in the Martian ionosphere

, 1997
The structure and dynamics of the Martian ionosphere are believed to be strongly dependent on the nature, magnitude, and topology of its magnetic field, and whether or not Mars has an intrinsic magnetic field.

Phenomena in the ionosphere-magnetosphere system induced by injection of powerful HF radio waves into nightside auroral ionosphere [PDF]

, 2005
International audienceExperimental results from three ionospheric HF pumping experiments in overdense E or F regions are summarized. The experiments were conducted by the use of the EISCAT HF Heating facility located near Tromsø, Norway, allowing HF ...
