It deflects much of the charged material streaming from the Sun and helps keep the upper atmosphere from being stripped away too quickly. A 2025 modelling study adds a more complicated possibility: under the right geometry, the same magnetic environment […] The post For billions of years, Earth’s magnetic field may have been doing something unexpected: helping guide particles stripped from our upper atmosphere across the 385,000 kilometres to the Moon, where they became trapped in lunar soil — a 2025 finding that adds a surprising new argument for studying the regolith beneath a future Moon base. appeared first on Space Daily .
