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.

An overview of the petrography and petrology of particles from aggregate sample from asteroid Bennu
Meteoritics &Planetary Science, Volume 60, Issue 5, Page 979-996, May 2025.Abstract The OSIRIS‐REx mission returned a sample of regolith from the carbonaceous asteroid Bennu in September 2023. We present preliminary in situ investigations of the petrology and petrography of selected particles ranging in size from 0.5 to 3 mm.

Implications of cohesive strength in asteroid interiors and surfaces and its measurement
Progress in Earth and Planetary Science, 2018 Recent observations and theory have indicated that rubble pile asteroids may have a small, but finite, level of tensile strength, allowing them to spin above their spin deformation limit as defined in Holsapple (Icarus 205:430–442, 2010).

Planetary Defence Activities Beyond NASA and ESA [PDF]
The collision of a significant asteroid or comet with Earth represents a singular natural disaster for a myriad of reasons, including: its extraterrestrial origin; the fact that it is perhaps the only natural disaster that is preventable in many cases ...

Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material
Meteoritics &Planetary Science, Volume 60, Issue 5, Page 1073-1094, May 2025.Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.Abstract Space weathering alters the surface materials of airless planetary bodies; however, the effects on moderately volatile elements in the lunar regolith are not well constrained. For the first time, we provide depth profiles for stable K and Fe isotopes in a continuous lunar regolith core, Apollo 17 double drive tube 73001/2.

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
