Moonbase Gravitron Control Room

Gravitron Control Room (Moonbase Command Hub)

Primary control hub for the Gravitron device on the Moonbase, where operators must wear thick protective helmets to shield against the lethal sonic and gravitational forces generated by the machine. This secured compartment serves as the central command center for both legitimate weather control operations and high-stakes sabotage (e.g., redirecting relief ships toward the sun or lifting Cybermen saucers). Key features include exposed gravitron controls, oxygen mask drop panels, and crowded consoles for monitoring relief rockets and Cybermen signals. The room is a linchpin for both legitimate operations and Cyberman sabotage, with machinery humming amid tension, betrayal, and isolation. Its redirection capabilities make it a high-stakes battleground for control of the Moonbase and Earth's climate stability. Key events include: - Evans (Cyberman-controlled): Bursts in, knocks Benson unconscious, seizes a helmet, and mans the console to redirect a relief ship toward the sun under off-screen Cyberman commands. - Benoit: Mans the controls to disengage safety cutouts and manually lower the probe, redirecting the Gravitron's power to the lunar surface to lift Cybermen saucers. - The Doctor: Rips the control device off a dazed Evans while Ben and Jamie prepare to drag him away. The room is also referred to as the Moonbase Control Room in some contexts, reflecting its dual role as both a specialized Gravitron control center and a general command hub for the base.
