Fractionated noble gases in the nakhlite Martian meteorites [PDF]

open access: yes, 2016
Noble gases measured in Martian meteorites are frequently a mixture of different components, ranging from Martian interior and unfractionated and fractionated atmosphere, to cosmic ray produced isotopes and terrestrial contamination. Here we focus on the

Effect of the Net Charges Carried by Dust on Martian Atmospheric Temperature

open access: yesGeophysical Research Letters, 2023
Dust particles suspended in the dusty Martian atmosphere are prone to being charged. In this paper, we investigate the effect of the net charges carried by dust particles on the radiative properties of Martian dust.

Modeling the variations of Dose Rate measured by RAD during the first MSL Martian year: 2012-2014 [PDF]

open access: yes, 2015
The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) rover Curiosity, measures the {energy spectra} of both energetic charged and neutral particles along with the radiation dose rate at the surface of Mars. With these first-ever measurements on the Martian surface, RAD observed several effects influencing the galactic ...

Very high elevation water ice clouds on Mars: Their morphology and temporal behavior [PDF]

open access: yes
Quantitative analysis of Viking images of the martian planetary limb has uncovered the existence and temporal behavior of water ice clouds that form between 50 and 90 km elevation.

The nakhlite meteorites provide evidence for mineralization of martian CO2 by carbonation of silicates [PDF]

open access: yes, 2013
Evidence from the Lafayette meteorite shows that carbon dioxide could have been sequestered very effectively from the martian atmosphere by mineral ...

Measurements of Forbush decreases at Mars: both by MSL on ground and by MAVEN in orbit

open access: yes, 2017
The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) Curiosity rover, has been measuring ground level particle fluxes along with the radiation dose rate at the surface of Mars since August 2012. Similar to neutron monitors at

Identifying Landslides in Atla Regio on Venus

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract We performed a systematic search for landslides in the Alta Regio region of Venus, located from (16°S, 179°W) to (21°N, 147°W). Using data primarily from Magellan Cycle 1 radar imagery, we identified 29 landslides in this region. There were 19 previously identified across the entire surface (Malin, 1992, https://doi.org/10.1029/92je01343 ...

Gravity and Magnetic Field Signatures in Hydrothermally Affected Regions on Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Multiple lines of evidence indicate that liquid water‐rock interactions occurred on ancient Mars, particularly within the crust, where hydrothermal systems have been hypothesized. Such hydrothermal circulation (HC) can significantly lower temperatures in the crust, thereby restricting the viscoelastic relaxation of impact craters. Craters with
