Description
Caroline E. Caplan and colleagues simulate space weathering on ice-coated silicon in a 2026 lab study. Airless bodies face electron bombardment, and ice-rich shadowed spots on the Moon and Mercury are prime sites. Earlier work hinted that electrons drive odd oxygen exchange between ice and the surface below at very low temperatures.
Fine infrared mapping showed new silicon-oxygen bonds formed where electrons struck the ice layer. The amount of surface oxidation depended on electron energy, ice amount, and timing of ice placement. Electron images confirmed thicker oxide in zones of strongest interaction, suggesting cosmic rays may reshape cold dust grains more than once thought.
