    Earth's magnetic field creates a previously undetected pocket of protection from radiation on the moon
    Illustration of the formation of the GCR cavity in the ecliptic plane. white lines from the Sun show the typical pattern of magnetic field lines in interplanetary space, referred to as the Parker spiral IMF. The magenta segment of the lunar orbit (dashed white circle) indicates the operational periods of LND, specifically from LP = 7.5 to 16.5 hM. The cylindrical spirals in two colors indicate two opposing directions of motion for GCR protons along the magnetic field lines. Shielded by Earth’s magnetic field, two regions of reduced GCRs in the near-Earth space are expected to exist, as marked by the shadowed areas...
