Moonbase

A moonbase was a base built on a moon.

20th century
In 1903, after receiving a wealth of information from the future, Grigori Rasputin foresaw the lunar space station. (AUDIO: The Wanderer)

Giant Leap Base was said by Greta to be the first moonbase on the Moon. (AUDIO:  The Beginning)

In the 1960s, the United States government built Moonbase Eisenhower on the far side of the Moon using alien technology. It was destroyed by the Sixth Doctor on 23 November 1963. (AUDIO: 1963: The Space Race)

By 1969, the Soviet Union and the United States had secretly established Gagarin Base and Horizon Base, respectively, in Mare Tranquillitatis. (PROSE: Moon Blink)

As early as the 1970s, UNIT planned the construction of a moonbase with assistance from Liz Shaw. (AUDIO: The Cloisters of Terror)

By 1997, IIF was planning to build a nuclear-waste storage facility on the Moon by 1999. (PROSE: The Dying Days)

21st century
In 2006, UNIT set up Moonbase One as a scientific research station. (PROSE: Horror of the Space Snakes)

In 2023, Moonbase One was given to World State and renamed Moonbase Laika. (PROSE: Horror of the Space Snakes)

A moonbase was built on the Moon during the 21st century, with a limited crew of scientists. It was under the control of International Space Command.

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 Telosian 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)

At another point in the 21st century the Moonbase controlled the Earth's T-Mat system and was attacked by the Ice Warriors. (TV: The Seeds of Death)

Later history
Some billionaires went to the Moonbase to escape the plagues (PROSE: A Star's View of Caroline) that ravaged Earth in the years before the 22nd century Dalek invasion. Moon stations were active by this time. (TV: The Dalek Invasion of Earth) The Moonbase was still cut off from post-invasion Earth in the 2190s, (AUDIO: An Earthly Child) though the human colonists there were rescued shortly afterwards. (AUDIO: Quinnis)

There was a Moonbase Academy in the 24th century. (PROSE: The Dimension Riders)

Lunar-1 was a moonbase which was in operation by the year 2400. That year, Lunar-1's space scanners were blocked by an electron shield which the Daleks spread to mask their journey to Venus in anticipation of their invasion of the solar system. (COMIC: Invasion of the Daleks)

Other moonbases
Qurra, a Silurian, killed the inhabitants of a human moonbase. Jen Yates activated a doomsday device before she died, wiping out the populace of the colony planet below. Qurra's guilt at her involvement saw her adopt Yates' identity, which she only spurned, remembering who she truly was, when the Seventh Doctor, Ace and Benny visited her. Consumed with guilt, she left the base without a spacesuit, killing herself. (PROSE: Cold War)

Undated events
The Eleventh Doctor claimed to have helped a "possessed orchestra" on the moonbase. (HOMEVID: Good Night)

Alternate timelines
In an alternate timeline created by Elizabeth Klein, a Moonbase was attacked by the Selachians in 2044. (AUDIO: The Architects of History)
