Turning data from space into action for Earth
Happy Earth Day, 22 April – a global call to act and protect our planet. At the European Space Agency, that action begins in orbit, where satellites deliver a continuous, global view of Earth and track environmental change. Working with partners, ESA turns this stream of data into actionable information, helping governments and communities respond faster and more effectively to climate-driven risks. Here are two examples of how space technology is being used to anticipate threats to safeguard food security and public health.
