Cao F. et al. Mineralogy, Petrology, and Geochemistry of Ungrouped Achondrite Northwest Africa (NWA) 4587 [#1880]
NWA 4587 is an ungrouped basaltic achondrite with isotopic affinities to the carbonaceous reservoir of the early Solar System. We investigate its mineralogy, petrology, and geochemistry to constrain mineral compositions and thermal–magmatic evolution.

Hsu W. et al. Shengli: An Eagle Station Pallasite from a Layered, Partially Differentiated Carbonaceous Planetesimal [#1072]
The meteorite Shengli shows affinities to PES, and the similarity extends to the refractory HSE contents of Shengli, GAZB, Milton, and Khatgal point to a common origin of their metals from an IVB iron parent body within a CC isotopic reservoir.

Schmeling M. et al. Development of Laser Surface Cleaning for Genesis and Other Space-Related Samples [#1244]
Dry laser cleaning was tested on silicon wafers serving as proxies for Genesis samples. It showed good results in removing contamination and after refinement will be a promising alternative to the traditional cleaning methods currently employed.

Dall’Asén A. G. et al. Characterization of Carbonaceous Meteorite Northwest Africa 6603 by Microscopy and Spectroscopy Techniques [#1553]
Optical microscopy, Raman spectroscopy, Atomic Force Microscopy and Fourier-Transform Infrared spectroscopy were used to study in detail the topography and material composition of carbonaceous chondritic meteorite Northwest Africa (NWA) 6603.

Dowling A. R. et al. Do Carbonates in Thermally Metamorphosed CMs Record Different Shock-Related Microstructural Responses than Those in Unmetamorphosed CMs? [#1609]
Carbonates in thermally metamorphosed CM chondrites show nanoscale porosity and preserved deformation features, consistent with high-temperature shock heating during impact-related metamorphism, which are absent in unmetamorphosed CMs.

Rappenglück M. A. et al. Towards a Methodological Validation of Digital Terrain Models as a Potential Impact Criterion: Requirements, Constraints, and a Roadmap for Empirical Testing [#1078]
This contribution outlines a systematic framework to test the diagnostic potential of DTM-derived morphometric signatures for impact craters across planetary bodies, clarifying their current heuristic role and the requirements for future validation.

Sawicki J. A. Raman Parameters of Diamonds in Impactites and Meteorites [#1017]
The review of distinct differences in Raman D-band parameters of carbon hexagons in diamond, lonsdaleite and graphite allotropes, allows to distinguish them in materials formed under extreme pressure, temperature and impact conditions.

Anae M. et al. Investigating Potassium Distributions Along Temperature Gradients at High Pressure with Implications for the Ar-Ar Chronology of Impact Melts [#1473]
This work experimentally investigates potassium displacement at high pressure and various temperatures as it relates to the thermal gradients of impact melts and subsequent Ar-Ar anomalies in ordinary chondrites.

West A. et al. Hydrocode Modeling of Impact Craters: Chiemgau Low-Altitude Airburst Impact Strewn Field, Germany [#1085]
We report on the first known hydrocode modeling of a large impact crater strewn field. Field observations and laboratory results (large clusters of shallow craters, shock, melting, glasses) are well reproduced by the modeling.

Thanks everyone, ’til next year!
