Martian surface weathering studies [PDF]

open access: yes
The nature of the Martian surface was characterized by means of its reflectance properties. The Mariner 9 photography was used to establish terrain units which were crossed by the Mariner 6 and 7 paths. The IR reflectance measured by the IR spectrometers

Martian Surface and Atmosphere Workshop

open access: yesEos, Transactions American Geophysical Union, 1992
The NASA‐sponsored Martian Surface and Atmosphere Through Time Study Project convened its first major meeting at the University of Colorado in Boulder, September 23–25, 1991. The workshop, co‐sponsored by the Lunar and Planetary Institute (LPI) and the Laboratory for Atmospheric and Space Physics at the University of Colorado, brought together an ...

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

open access: yesJournal 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.

Mars Crater Production Function Based on Mapped Crater Populations

open access: yesSpace: Science & Technology
The Martian isochrons are the basis in analyzing the impact flux and surface dating, and currently, they are usually derived from those of the Moon because no samples have been collected from Mars.

Reflectance spectroscopy of palagonite and iron-rich montmorillonite clay mixtures: Implications for the surface composition of Mars [PDF]

open access: yes
Because of the power of remote sensing reflectance spectroscopy in determining mineralogy, it was used as the major method of identifying possible mineral analogs of the Martian surface. A summary of proposed Martian surface compositions from reflectance

Martian Surface Paleotemperatures from Thermochronology of Meteorites

open access: yesScience, 2005
The temporal evolution of past martian surface temperatures is poorly known. We used thermochronology and published noble gas and petrographic data to constrain the temperature histories of the nakhlites and martian meteorite ALH84001. We found that the nakhlites have not been heated to more than 350°C since they formed.

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

open access: yesJournal 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.

Reconfigurable Intelligent Surface Deployments for Mars: Communication and Localization Across Diverse Terrains

open access: yesIEEE Open Journal of the Communications Society
Space exploration has witnessed a steady increase since the 1960s, with Mars playing a significant role in our quest for further knowledge. As the ambition to colonize Mars becomes a reality through the collaboration of private companies and space ...

Physiological and technological considerations for Mars mission extravehicular activity [PDF]

open access: yes
The nature of the suit is a function of the needs of human physiology, the ambient environment outside the suit, and the type of activity to be accomplished while in the suit.

Origin of Late Noachian‐Early Hesperian Valley Networks on Mars: Insights From Landform Evolution and Ice Sheet Modeling

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.
