NASA's TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission has gathered its first clues to how space weather affects Earth's magnetic field. In a new paper published in the Journal of Geophysical Research: Space Physics, researchers break down

NASA's TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission has gathered its first clues to how space weather affects Earth's magnetic field. In a new paper published in the Journal of Geophysical Research: Space Physics, researchers break down how these interactions work after analyzing initial observations from the first year of the mission.
