Lunar Samples Show Earth's Magnetosphere Slows Solar Wind

A Chinese study, based on noble gas analysis of lunar farside samples from the Chang'e 6 mission, has revealed a new interaction between Earth and the solar wind. The findings indicate that Earth's magnetosphere significantly slows down the solar wind before it reaches the Moon's nearside. This discovery suggests Earth's magnetic field acts as a natural 'speed governor,' leaving a permanent imprint in the lunar soil's noble gas record.
