Deeper solar wind penetration on the Moonβs farside from noble gas records
Nature Geoscience, Published online: 15 July 2026; doi:10.1038/s41561-026-02042-w
Krypton and xenon in lunar farside soils are derived from solar wind and suggest deeper penetration because the solar wind is not slowed by Earthβs magnetosphere. This contrasts with the nearside, according to noble gas analyses of soil samples collected by the Changβe-6 mission.
