NASA’s TRACERS Studies Explosive Process in Earth’s Magnetic Shield
Wednesday, July 16, 2025
High above us, particles from the Sun hurtle toward Earth, colliding with the upper atmosphere and creating powerful explosions in a murky process called magnetic reconnection. A single magnetic reconnection event can release as much energy as the entire United States uses in a day. NASA’s new TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission will study magnetic reconnection, answering key questions about how it shapes the impacts of the Sun and space weather on our daily lives.
