That's because the reduced strength of Earth's magnetic field allows the orbiters to be pummeled by incoming solar radiation that disrupts technological systems. Typically, this only causes low ...
Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.
The research team found that the lunar magnetic field intensity may have rebounded around 2.8 billion years ago, challenging the previously accepted conclusion that the lunar magnetic field ...
