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.

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.

Microtextures and structures in metal–sulfide grains in NWA 869 meteorite and their relation to thermal history of L‐chondrite parent body

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.

Magnesium phosphate in the Cold Bokkeveld (CM2) carbonaceous chondrite

Meteoritics &Planetary Science, EarlyView.
Abstract Hydrous Mg‐phosphate was first described from astromaterials in particles returned from the C‐type asteroid Ryugu, and has subsequently been found in samples of the B‐type asteroid Bennu and CI1 carbonaceous chondrites. This phase may have been highly significant as a source of bioessential compounds for early Earth.

Evidence for late impact‐induced metasomatism on the brachinite parent body recorded by a phosphate assemblage in NWA 7828

Meteoritics &Planetary Science, EarlyView.
Abstract Brachinites are a group of ultramafic achondritic meteorites thought to sample a planetesimal from the early inner solar system. They yield predominately ancient crystallization ages within 4 Ma of CAI formation, and while the formation mechanism for these samples is debated, they are widely thought to be partial melt residues from a ...

Matera: A not so ordinary H5 chondrite breccia with very low density and high porosity

Meteoritics &Planetary Science, EarlyView.
Abstract On the evening of February 14, 2023, at 17:58 UT, a fireball was detected by three cameras of the Italian PRISMA network (FRIPON network). The first samples of the Matera meteorite, collected 3 days after the fall, lay on the balcony of a private home.

The sub‐μm petrography of the observed meteorite fall Winchcombe—A complex array of pristine and altered chondrite components

Meteoritics &Planetary Science, EarlyView.
Abstract Samples of observed meteorite falls provide important constraints on alteration histories of Solar System materials. Due to its rapid collection, terrestrial alteration in the observed Mighei‐type (CM) carbonaceous chondrite fall Winchcombe was minimal.

Cosmic ray exposure ages and pre‐atmospheric shielding of Omani meteorites: Implications for 14C and 14C/10Be terrestrial ages of meteorites from hot and cold deserts

Meteoritics &Planetary Science, EarlyView.
Abstract We present isotope concentrations of the light noble gases He and Ne for samples from five well‐documented strewnfields and two individual meteorites from the Omani desert. Cosmogenic (22Ne/21Ne)cos for the strewnfield samples are low, as expected considering the total known masses.

Ultraviolet C (UV‐C) Light Therapy for Equine Ulcerative Keratomycosis—An In Vitro Study

Veterinary Ophthalmology, EarlyView.
ABSTRACT Objectives To assess if an affordable, commercially available 275 nm ultraviolet C (UV‐C) device can inhibit fungal pathogens associated with equine keratomycosis and to establish the optimal exposure time/dose required in vitro. Methods Fungal inhibition zone surface areas of isolates from two fungal genera (Aspergillus and Fusarium spp ...

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.
