The first of four Cyberman stories in the Second Doctor’s three-season run, this is not the most highly regarded, but it’s no means unpopular either, a solid example of its type. For our purposes, however, what’s interesting is that it attempts to take a hard sci-fi tone, something we don’t often see on the show. It’s also the first time we’ve visited a world other than Earth that actually exists, so that it’s possible to make some concrete statements about it.
Where & When
The story takes place in and around the eponymous base, an unnamed international station located on the Moon. The year is given as 2070, which later stories will confirm is at a time when mankind has expanded through at least the inner solar system (Waters of Mars is set in 2059), but has yet to develop faster-than-light travel.
