Meteoritics &Planetary Science, Volume 60, Issue 3, Page 506-528, March 2025.Abstract JAXA's Hayabusa2 sample return mission visited the volatile‐rich carbonaceous (C‐type) asteroid (162173) Ryugu with the aim of ground‐truthing remote observations, returning a pristine sample from a C‐type asteroid, and strengthening links between asteroids and the meteorite collection. Here, we have conducted a systematic study of coarse (>10

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 529-543, March 2025.Abstract Solar wind Fe and Mg fluences (atoms/cm2) were measured from Genesis collectors. Fe and Mg have similar first ionization potentials and solar wind Fe/Mg should equal the solar ratio. Solar wind Fe/Mg is a more valid measure of solar composition than CI chondrites and can be measured more accurately than spectroscopic photospheric abundances ...

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.

VIS‐to‐MIR reflectance and Raman spectroscopy of the CM2 NWA 12184 carbonaceous chondrite
Meteoritics &Planetary Science, Volume 60, Issue 3, Page 570-595, March 2025.Abstract The spectral analysis of CM meteorites can help to constrain the mineralogical composition of their parent body, the C‐type asteroids. The CM2 NWA 12184 was spectrally examined employing seven complementary techniques at different spatial resolutions, including VIS‐to‐MIR reflectance and Raman spectroscopy.

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 616-631, March 2025.Abstract Results of microanalysis study of NWA 869 meteorite, an ordinary chondrite, where silicates, Fe‐Ni alloys, and troilite are major constituents, are reported. The presented study of microtextures in metallic and sulfide grains provides information on processes occurring from the asteroid's accretion, through the impacts until cooling.

Northwest Africa 13489: A Strongly Metamorphosed Ungrouped Carbonaceous Chondrite
Meteoritics &Planetary Science, EarlyView.Abstract NWA 13489 is a meteorite that has been classified as a brachinite. Brachinites are olivine‐rich primitive achondrites representing residual products after a variable degree of silicate melt extraction on a barely differentiated, noncarbonaceous asteroid.
