Spacecraft ground support refers to the systems and services that assist in the preparation, launch, and operation of spacecraft from Earth. This includes facilities for testing and assembling spacecraft, as well as equipment for monitoring and controlling missions. Ground support ensures that all systems function correctly before and during a mission. Additionally, ground support teams are responsible for communication with spacecraft, providing data analysis, and troubleshooting any issues that arise. They work closely with organizations like NASA and SpaceX to ensure successful missions, from initial design to post-launch operations.
