Space systems refer to the various technologies and components that work together to operate in outer space. This includes satellites, spacecraft, and ground control stations. These systems are designed for a range of purposes, such as communication, weather monitoring, navigation, and scientific research. A key aspect of space systems is their ability to collect and transmit data back to Earth. For example, NASA uses space systems to explore planets and gather information about the universe. Additionally, commercial companies are developing their own space systems for purposes like global internet coverage and Earth observation.
