How have satellites improved?

Satellites have significantly improved in terms of technology, miniaturization, and functionality. Advances in materials and engineering have allowed for smaller, lighter satellites with enhanced capabilities, such as high-resolution imaging and real-time data transmission. Furthermore, the development of constellations of small satellites enables more comprehensive coverage and faster data collection. Enhanced propulsion systems and power sources have also extended their operational lifespans and expanded their applications across various fields, including communication, weather forecasting, and Earth observation.
