A
mission control center (
MCC, sometimes called a
flight control center or
operations center) is a facility that manages
space flights, usually from the point of launch until landing or the end of the mission. It is part of the
ground segment of spacecraft operations. 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.
