Overview

• Samples from asteroid Ryugu show evidence of space weathering, likely caused by high-energy particles and micrometeoroid bombardment.
• Electron holography used in the study reveals detailed structural and magnetic properties of Ryugu's surface.
• Findings include the alteration of magnetic properties in magnetite particles, attributed to high velocity micrometeoroid impacts.
• The research enhances understanding of early solar system magnetic fields and could influence future remote sensing interpretations.
• Studies suggest potential implications for estimating the degradation of spacecraft due to space dust impacts.
