Where does Earth's mysterious 'ring current' come from? NASA and the US Space Force are launching a mission to find out

NASA, working with the Space Force, plans to launch a space weather mission later this month to study a strange "ring current" surrounding our planet.

The payload also aims to answer a big question: do these particles come from the sun, or from Earth?

NASA's STORIE mission will launch as soon as this month on a SpaceX resupply mission to the ISS.
