Every day, people rely on about fifty satellites orbiting Earth, which are crucial for many aspects of modern life. These include geolocation services like GPS, weather forecasting, and the synchronization of global banking systems. Major satellite networks include the American GPS, the European Galileo, the Russian Glonass, and the Chinese Beidou, each consisting of around thirty satellites. These systems provide essential data that helps in everything from navigation to tracking weather patterns. In France, for instance, about 90% of the data used by Météo-France comes from satellites. Since 2022, new satellites have been launched to improve the accuracy of weather forecasts and to detect rapidly forming storms more effectively. Satellites also play a key role in keeping international banking systems in sync. This synchronization ensures that stock exchanges operate smoothly and that individuals can use credit cards and withdraw money from ATMs without issues. Beyond finance, satellite-based time synchronization is important for managing electricity distribution networks. If these systems were to fail, the entire electrical grid could become unstable, potentially leading to blackouts and power outages with serious and unpredictable consequences. Space technology has influenced many everyday items beyond satellites. For example, smartphone cameras were developed using technology originally created by NASA's Jet Propulsion Laboratory in the 1960s. Similarly, the development of modern disposable diapers can be traced back to NASA's research into absorbent materials for astronauts' suits. This innovation eventually led to the creation of the baby diaper industry. Another example is the survival blanket, which was first designed to protect satellites from extreme temperatures and has since been adapted for use in emergency situations and outdoor gear. Space activities are seen as a direct extension of human endeavors on Earth, emphasizing their importance in modern societies. To highlight this, France is hosting an international summit on space in Paris on September 9. The event aims to bring together experts and leaders to discuss the future of space exploration and its impact on global challenges.
