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 ...

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 ...
