Earth Space Station

Earth Space Station was a space station in Earth orbit. When the First Doctor warned Earth that a spaceship crewed by Daleks and Voords was en route to the solar system, the Earth Space Station began tracking the ship on their instruments. When the scientists on the station lost track of the ship, the chief scientist decided there was no chance they would reach Earth, and only minor precautions were taken.
