Magnetism earth defends astronauts

Astronauts exploring the moon will be protected from the flow of electrons from the sun when the moon is in the earth's magnetic field for about 7 consecutive days each month.

Robert Winglee of the University of Washington, Seattle, said: "Some places on the moon will be protected from the earth in a time equal to half of the moon's orbit."

Robert explained that there are very few molecules that carry the maximum charge that can reach the moon's equator once it is shielded by the Earth's magnetosphere. While solar storms can still endanger astronauts walking in space, they will have enough time to return to safe areas.
