MDSCC Training and Visitor Center is the public interpretation building beside the operational Madrid Deep Space Communications Complex. It is currently closed to visitors and schools until further notice. Its three exhibition rooms, workshop area, and auditorium explain NASA missions, the Deep Space Network, astronomy, and Solar System exploration through models, murals, original objects, and multimedia; a real Apollo 15 Moon rock is the permanent exhibition's centrepiece, and the building overlooks the 70-metre DSS-63 antenna.
