The European Remote Sensing Satellite 2 (ERS-2) was a key mission of the European Space Agency (ESA) focused on Earth observation. It was the successor to ERS-1, building on its capabilities with improved instruments and extended mission objectives. The primary objective of ERS-2 was to continue and enhance the observations started by ERS-1, providing valuable data for environmental monitoring, climate studies, and oceanography. It aimed to observe the Earth's surface, atmosphere, and oceans with high precision and over long periods.
