Space weather tour

Space weather refers to conditions on the Sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the performance and reliability of space-borne and ground-based technological systems and that can affect human life or health.

The Sun is the main driver of space weather near Earth. Other phenomena such as galactic cosmic rays also contribute to space weather.
