Meteoritics &Planetary Science, Volume 60, Issue 12, Page 2913-2934, December 2025.Abstract Enstatite chondrites formed under extremely reducing conditions in the protoplanetary disk. They are derived from two or more parent bodies, EH and EL, and both EH and EL groups contain petrologic type 3–6 samples. The rare lithophile‐ and halogen‐bearing sulfide, djerfisherite, occurs in low abundance in enstatite chondrites, most frequently ...

Boulders on Bennu: Low Apparent Thermal Inertia Caused by Thermal Fatigue Fractures
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract Boulders covering the surfaces of asteroids Bennu and Ryugu have apparent thermal inertias substantially lower than their meteorite analogs. This has led to the inference that boulders on Bennu may be unlike any known meteorite. However, samples returned from Ryugu have a thermal inertia 3.5 times higher than the apparent thermal inertia ...

, 2019 We present in this study the effects of short-term heating on organics in the Tagish Lake meteorite and how the difference in the heating conditions can modify the organic matter (OM) in a way that complicates the interpretation of a parent body’s ...

Petrography of phosphates in CI and CY carbonaceous chondrites
Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2594-2622, November 2025.Abstract Phosphate minerals are significant carriers of volatiles (e.g., OH) and halogens in chondritic material; however, their origin in most groups of carbonaceous chondrites remains poorly characterized. We have determined the abundance, morphology, texture, and composition of phosphate grains in aqueously altered CI chondrites and in hydrated and ...

Regolith behavior under asteroid-level gravity conditions: low-velocity impact experiments
, 2018 The dusty regolith covering the surfaces of asteroids and planetary satellites differs in size, shape, and composition from terrestrial soil particles and is subject to very different environmental conditions.

Special issue “Science of solar system materials examined from Hayabusa and future missions (II)” [PDF]
, 2017 Six years have passed since the first asteroid sample was returned from the S-type near-Earth asteroid 25143 Itokawa by the JAXA’s Hayabusa mission in 2010 (Yada et al. 2014). Considerable progress has been made in the study of surface regolith materials
