Moonbase (disambiguation)for other, similarly-named pages.
Circa the 2050s, the Gravitron (a device capable of gravitationally manipulating the tides on Earth and through them its weather) was installed. By the 2070s, it was connected to the Earth by monthly shuttle rocket runs.
In 2070, the base seemed to be struck by a disease. This was in fact a prelude to an attack by the Cybermen. The Cybermen wanted to take the base and use the Gravitron to destroy life on Earth, eliminating it as a threat. They failed, and though the normal operations of the Gravitron were briefly disturbed, eventually it resumed normal operations. (TV: The Moonbase)
In the 2190s, the Moonbase was still cut off from the Earth following the Dalek invasion. (AUDIO: An Unearthly Child) However, the human colonists stranded in the Moonbase were rescued shortly afterwards. (AUDIO: Quinnis)
