Martian Surface and Atmosphere Workshop

Eos, 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 ...

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Catalytic/Protective Properties of Martian Minerals and Implications for Possible Origin of Life on Mars

Life, 2018
Minerals might have played critical roles for the origin and evolution of possible life forms on Mars. The study of the interactions between the “building blocks of life„ and minerals relevant to Mars mineralogy under conditions mimicking the

Impacts of Carbon Dioxide Deposition on Martian Near‐Surface Wave Activity

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract A prominent feature of Mars' winter atmosphere is near‐surface baroclinic wave activity. These waves exert strong control on dust storm variability and contribute to transport of heat, momentum, and dust. Using a suite of Mars general circulation model simulations, we investigate an underexplored connection between near‐surface wave activity ...

Time and Length Scales of the Martian Atmospheric Turbulence as Observed by the InSight Lander

Geophysical Research Letters
We provide a statistical analysis of the Martian near‐surface atmospheric turbulence based on in situ wind observations from NASA's InSight lander. We focus on the variations in length and time scales of the Martian atmospheric turbulence caused by the ...

Modeling Ganymede's Surface Charging in Preparation for the JUICE Mission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The European Space Agency's (ESA) JUICE mission (JUpiter ICy moons Explorer) is en route to the Jovian system to characterize Ganymede's subsurface ocean. Determining the ocean's conductivity and depth requires precise measurements of its induced magnetic field at the position of JUICE.

Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

Were There Tides on Ancient Mars?

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Tides are a key component in the Earth system as they help regulate climate and sustain life. Mars very likely had a surface ocean around 4–3 billion years ago. The NASA Curiosity Rover and the CNSA Zhurong Rover were sent to Gale Crater and the Vastitas Borealis Formation (VBF) on Mars to explore the surface and search for evidence of the ...

ARAMIS: a Martian radiative environment model built from GEANT4 simulations

Journal of Space Weather and Space Climate
A new model of the Martian surface radiative environment has been built: Atmospheric RAdiation Model for Ionizing spectra on martian Surface (ARAMIS). Based on Monte Carlo calculations, it offers high computational flexibility for surface flux spectra ...
