NASA’s TRACERS Studies Magnetic Explosions above Earth | NASA Goddard

NASA's TRACERS mission, or the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, will fly in low Earth orbit through the polar cusps, funnel-shaped holes in the magnetic field, to study magnetic reconnection and its effects in Earth's atmosphere. 

Magnetic reconnection is a mysterious process that happens when the solar wind, made of electrically charged particles and magnetic fields from the Sun, collides with Earth's magnetic shield, causing magnetic field lines to violently snap and explosively fling away particles at high speeds. This process has huge impacts on Earth, from causing breathtaking auroras to disrupting communications and power grids on Earth. 

TRACERS is launching no earlier than summer 2025 aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California.
