Lobate Forms Around Craters on the Moon and Mercury: Origin From Landslides, Ejecta Flows and Modification Stage Collapse

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Lobate forms emanate from impact craters and have morphologies indicating ground‐hugging emplacement via flow. We present global surveys of lobate forms on the Moon and Mercury. Very few examples have previously been reported on either body, with debate over their interpretation as either crater rim landslides or ejecta flows.

Seven-year climatology of dust opacity on Mars [PDF]

open access: yes, 2012
This paper describes the procedure we have used to produce multi-annual dust scenarios for Martian years 24 to 30 from a multi-instrument dataset of total dust opacity observations.

On the Crustal Architecture of the Terrestrial Planets

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Understanding the structure and composition of planetary crusts is fundamental for unraveling the diverse geologic pathways of rocky bodies in the solar system. In recent years, geophysical missions have shed light on the crustal architecture of the Moon and Mars.

Reviewing Martian Atmospheric Noble Gas Measurements: From Martian Meteorites to Mars Missions

open access: yesGeosciences, 2020
Martian meteorites are the only samples from Mars available for extensive studies in laboratories on Earth. Among the various unresolved science questions, the question of the Martian atmospheric composition, distribution, and evolution over geological ...

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

open access: yes, 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 ...

Deep Learning‐Based Automated Segmentation of Layered Crater Ejecta on Mars

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Layered crater ejecta (LCE) with fluidization on Mars is generally believed to be related to the near‐surface ice‐bearing deposits. The improvement in the resolution of planetary image data has led to the discovery of more and more LCE, providing support for further research on the formation and geological significance of layered ejecta ...

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

open access: yesGeofísica 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.

Evaluating Local Ionization Balance in the Nightside Martian Upper Atmosphere during MAVEN Deep Dip Campaigns

open access: yesAstrophysical Journal, 2019
Combining the Mars Atmosphere and Volatile Evolution (MAVEN) measurements of atmospheric neutral and ion densities, electron temperature, and energetic electron intensity, we perform the first quantitative evaluation of local ionization balance in the ...
