ESA / About Us / Exhibitions / Ready-to-use material

Space weather refers to the environmental conditions in space as influenced by solar activity. For our daily lives and routine economic activities on planet Earth, the conditions within the Earth's magnetosphere, ionosphere and thermosphere are particularly important, as dynamic changes in the environment caused by the Sun and the solar wind can influence the functioning and reliability of spaceborne and ground-based systems and services, thereby potentially endangering human health and wellbeing through impact on this infrastructure.
