NASA Van Allen probes confirm Earth as giant particle accelerator

NASA Van Allen probes confirm Earth as giant particle accelerator

The NASA Van Allen twin probes launched last year have revealed that the Earth is a giant particle accelerator. Recently it was reported that particles in the magnetosphere sometimes accelerate across distances of a few hundred meters. But the newer discovery shows the acceleration can occur across hundreds of thousands of kilometers. The data will be helpful to to scientists helping satellite operators and the International Space Station to predict and prepare for the destructive tendencies of the seemingly random fluctuations that can occur in the magnetosphere.

A spacecraft taking humans to explore the moon and beyond has to be able to carry the crew, air, fuel, water, and food to serve the entire mission. Finding ways to reduce the amount of one of those items that has to be packed in the ship leaves more space for others.
