Aiming to uncover the physics that power the auroras that crown Earth's poles, five tiny probes have been launched into space for a synchronized orbital dance to locate where the trigger is pulled to create the eerily magnificent displays. Each of the 282-pound spacecraft is equipped with identical suites of instruments to examine the origin of space explosions known as substorms. The events start with the soup of ionized particles from the sun, called the solar wind, buffeting the Earth at a million miles per hour. Some of that energy gets trapped in the magnetic field, causing the field lines to stretch back in the direction opposite the sun like rubberbands. But when stretched too far the lines snap, releasing the energy that generates shimmering auroral displays.
