X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 405-426, March 2026.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

Drelów, the 13th and latest meteorite fall in Poland—A typical L6 chondrite with shock veins

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 466-486, March 2026.
Abstract On Tuesday, February 18, 2025, at 18:04:14 local time, residents of Poland observed a bright fireball registered by many Polish fireball stations belonging to the Skytinel Network established a few months before by Mateusz Żmija. Thus, the meteoroid's orbit, atmospheric trajectory, and the strewn field were calculated, and over 70 fragments ...

Combining universal‐stage, backscatter electron imaging and electron backscatter diffraction for improved indexing of planar microstructures in quartz and plagioclase

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 487-503, March 2026.
Abstract Quartz and feldspar commonly develop planar microstructures due to shock metamorphism. These are generally investigated and indexed (identifying the crystallographic orientation along which they developed) using a universal stage (U‐stage) on a petrographic microscope.

Substitution of Fe3+ into anorthite in oxidized, Al‐deficient ferrobasaltic systems with implications for the petrogenesis of angrite meteorites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 427-443, March 2026.
Abstract Angrite meteorites are critically silica‐undersaturated igneous rocks with high Ca/Al and Fe/Mg, along with depletion in volatile lithophile elements Na and K such that they crystallize anorthite along with olivine and calcic pyroxene. The anorthite in angrites contains substantial Fe, and in NWA 1670 and NWA 1296, it is present at major ...
