NASA has delayed its TRACERS mission to no earlier than 2025 to provide additional preparation time for the crew. The mission will send twin satellites to explore how solar wind interacts with Earth’s magnetosphere, particularly through a process called magnetic reconnection. These high-speed solar particles can trigger auroras and impact satellites, astronauts, and communications. Managed by the University of Iowa and launching on a SpaceX Falcon 9, TRACERS is a key effort to understand and forecast space weather effects on Earth.
