Mid‐infrared detection and characterization of refractory inclusions in CM and CO chondrites: A non‐destructive approach for returned space samples

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 544-569, March 2025.
Abstract Refractory inclusions (RIs) in chondrites are widely used as tracers of early solar system formation conditions. In the context of sample‐return missions, a non‐destructive and non‐invasive analytical tool that can rapidly detect and characterize RIs in space samples during their early phase of study is highly needed.

Selective sampling of asteroids, the Moon, and Mars: Factors affecting the numerical abundances of members of meteorite groups

Meteoritics &Planetary Science, EarlyView.
Abstract Meteorite collection inventories show that many related meteorite groups have very different numerical abundances (e.g., lunar versus Martian meteorites; Eagle Station pallasites versus main‐group pallasites; eucrites versus diogenites; ungrouped Antarctic irons versus ungrouped non‐Antarctic irons; carbonaceous chondrite‐related (CC) iron ...

The Martian surface radiation environment – a comparison of models and MSL/RAD measurements

Journal of Space Weather and Space Climate, 2016
Context: The Radiation Assessment Detector (RAD) on the Mars Science Laboratory (MSL) has been measuring the radiation environment on the surface of Mars since August 6th 2012. MSL-RAD is the first instrument to provide detailed information about charged

The depth of the convective boundary layer and implications for a Walker-like circulation on Mars [PDF]

, 2011
Radio science observations indicate that the depth of the martian convective boundary layer varies strongly with surface height, although the surface temperature does not.

Simulating evaporative wet and dry cycles in Gale crater, Mars using thermochemical modeling techniques

Meteoritics &Planetary Science, EarlyView.
Abstract The aim of this work is to provide a model‐backed hypothesis for the formation of evaporites—sulfates, borates—in Gale crater using thermochemical modeling to determine constraints on their formation. We test the hypothesis that primary evaporites required multiple wet–dry cycles to form, akin to how evaporite assemblages form on Earth ...

Pairing relationships of howardites, eucrites and diogenites (HED) from the Miller Range ice fields, Antarctica

Meteoritics &Planetary Science, EarlyView.
Abstract We reevaluated pairing relationships among 56 Antarctic howardites, eucrites, and diogenites (HED) from the Miller Range ice fields (MIL) based on new measurements of cosmogenic radionuclides and bulk composition of 28 HED samples and one HED‐related dunite.

Sustainable colonization of Mars using shape optimized structures and in situ concrete

Scientific Reports, 2023
The major obstacle to Martian colonization is the mission cost which requires significant reduction. From the structural engineering point of view, importing materials and structural elements from Earth or massive excavations on the surface of Mars ...

Water induced sediment levitation enhances downslope transport on Mars [PDF]

, 2017
On Mars, locally warm surface temperatures (~293 K) occur, leading to the possibility of (transient) liquid water on the surface. However, water exposed to the martian atmosphere will boil, and the sediment transport capacity of such unstable water is ...

Olivine–gabbroic shergottites: A petrogenetic link between poikilitic and gabbroic shergottites

Meteoritics &Planetary Science, EarlyView.
Abstract Shergottites span a textural, mineralogical, and geochemical range, and finding links between the various petrologic and geochemical groups is of great interest as it provides insight into the conditions of the Martian interior. Here, we compare the texture, mineralogy, mineral chemistry, and geochemistry of REE‐enriched intrusive shergottite ...
