Solar flares are massive explosions that occur on the surface of the Sun, unleashing tremendous amounts of energy that can cause significant disruptions in various technological systems on Earth. These powerful bursts of energy can cause disturbances in the Earth’s ionosphere, leading to interference with high-frequency radio communications, satellite navigation signals, and even electric power grids.

The release of high-energy particles and radiation during a solar event can damage the sensitive electronic equipment onboard spacecraft and threaten the health of astronauts.
