Satellite design involves creating spacecraft that can operate in space for various purposes, such as communication, weather monitoring, or scientific research. Engineers consider factors like size, weight, power supply, and materials to ensure the satellite can withstand harsh conditions in orbit. The design process includes selecting components like antennas, sensors, and propulsion systems. Each satellite must also have a reliable communication system to transmit data back to Earth. Overall, effective satellite design is crucial for successful missions and achieving specific objectives, whether for NASA, commercial companies, or international organizations.
