Solar wind erosion of lunar regolith is suppressed by surface morphology and regolith properties - Communications Earth & Environment
Sputtering yields from solar wind exposure on lunar regolith are up to an order of magnitude lower than expected from prior modeling and calculations, according to laboratory-based experiments on real...

🌕🚀 Just published!
Solar wind erosion on the Moon? Much weaker than we thought!
Using real Apollo 16 lunar samples and 3D modeling, we provide the first realistic sputtering yields for lunar regolith.
