Oued Chebeika 002: A new CI1 meteorite linked to outer solar system bodies

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1441-1479, July 2025.
Abstract CI1 chondrites are rare meteorites with high scientific value. In fact, they are the most chemically primitive meteorites and show evidence of intense parent‐body aqueous alteration. They also share strong similarities with samples from Ryugu and Bennu asteroids returned by the JAXA Hayabusa2 and NASA's OSIRIS‐REx missions.

Earth's Minimoons: Opportunities for Science and Technology

Frontiers in Astronomy and Space Sciences, 2018
Twelve years ago the Catalina Sky Survey discovered Earth's first known natural geocentric object other than the Moon, a few-meter diameter asteroid designated 2006 RH120. Despite significant improvements in ground-based telescope and detector technology

Silicate–sulfide interaction within quenched melts of space weathered Ryugu grains

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1480-1501, July 2025.
Abstract The first few microns of the surface of airless bodies are subject to severe changes due to the harsh environment of space, known as space weathering. The Hayabusa2 sample return mission from the asteroid Ryugu provides the first opportunity to study these effects on a carbonaceous and hydrated body.

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

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1502-1519, July 2025.
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 ...

Experimental simulations of space weathering on pentlandite

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1555-1572, July 2025.
Abstract Pentlandite (Fe, Ni)9S8 is an important accessory mineral on asteroidal surfaces. It has been identified in returned regolith samples from asteroids Itokawa, Ryugu, and Bennu. Currently, systematic studies to understand the response of this mineral phase under space weathering conditions are lacking.

Low‐temperature dissociation of zircon in highly alkaline conditions: A cautionary note for studies on natural glasses of debated origin

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1573-1586, July 2025.
Abstract Dissociated zircon is largely used as a robust indicator of glasses generated by impact cratering and airbursts. The reaction of zircon dissociation, i.e. ‘ZrSiO4 → ZrO2 + SiO2’, requires high temperatures (>1670°C) only reached by extreme geological processes. Using high‐temperature experiments, this study shows that zircon can dissociate and

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

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1592-1608, July 2025.
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.
