A mission control center (MCC) is an entity that manages aerospace vehicle flights. The MCC is often part of a national aerospace agency or a large aerospace company. There are several such national agencies in the world, the top being:
The main task of an MCC is to manage space missions, usually from the point of lift-off until the landing or the end of the mission. A staff of flight controllers and other support personnel monitor all aspects of the mission using telemetry, and send commands to the vehicle using ground stations. Personnel supporting the mission from an MCC can include representatives of the attitude control system, power, propulsion, thermal, attitude dynamics, orbital operations and other subsystem disciplines. The training for these missions usually falls under the responsibility of the flight controllers, typically including extensive rehearsals in the MCC.
