Earth's Magnetic Field Could Help Protect Astronauts Working On The Moon
It has been 35 years since humans last walked on the moon, but there has been much recent discussion about returning, either for exploration or to stage a mission to Mars. However, there are concerns about potential radiation danger for astronauts during long missions on the lunar surface. A significant part of that danger results from solar storms, which can shoot particles from the sun to Earth at nearly the speed of light and can heat oxygen in the Earth's ionosphere and send it in a hazardous stream toward the moon. Earth is largely protected by its magnetic field, or magnetosphere, but new University of Washington research shows that some parts of the moon also are protected by the magnetosphere for seven days during the....READ ON.....
