The main objective is to explore implications of these results for assessing the relative importance of solar wind implantation versus micrometeorite impacts for lunar space weathering as well as three hypotheses (solar wind deflection, comet impact and dust transport) for swirl formation on the Moon. Results from this study can help to make connections between ordinary chondritic meteorites and asteroids, and put physical and chemical constraints on heating processes in the early solar system.en-USLunar swirlMoonRadiative transfer modelRemote sensingSpace weatheringLunar soilGeochemistrySolar windMoonSpace environmentCosmologyMeteoritesAsteroids
