Old NASA science satellite plunges back to Earth
An old NASA science satellite plunged uncontrolled from orbit and reentered over the Pacific on Wednesday.
Space weather as a research area investigates the variable conditions in space driven primarily by solar activity and their impact on the heliosphere, near-Earth environment, and technological systems. It encompasses the study of the solar magnetic field, flares, coronal mass ejections, high-speed solar wind streams, and energetic particles, and how these phenomena interact with planetary magnetospheres, ionospheres, and upper atmospheres. Research integrates observations, theory, and physics-based modeling to understand and predict geomagnetic storms, radiation belt dynamics, ionospheric disturbances, and associated hazards to satellites, communication and navigation systems, power grids, and human spaceflight.
