Ground control refers to the team of professionals responsible for monitoring and managing spacecraft operations from the Earth. This team ensures that all systems are functioning correctly and communicates with astronauts during missions. They play a crucial role in coordinating launches, landings, and any in-flight adjustments needed to keep the mission on track. The ground control team uses advanced technology and communication systems to maintain contact with spacecraft like those operated by NASA or SpaceX. They analyze data received from the spacecraft, troubleshoot issues, and provide guidance to ensure the safety and success of missions in space.
