Space systems refer to the various technologies and components designed for use in outer space. This includes satellites, spacecraft, and space stations, which are essential for communication, navigation, and scientific research. These systems are often developed by organizations like NASA and ESA to explore space and gather data about our universe. A key aspect of space systems is their ability to operate in the harsh environment of space, where conditions such as extreme temperatures and radiation can affect performance. Engineers and scientists work together to create reliable systems that can withstand these challenges, enabling missions to planets like Mars and beyond.
