Object
Moonbase Observation Dome
Transparent structure enclosing the Moonbase observation area, which cracks open from Cyberman sabotage, venting oxygen into vacuum. The dome serves multiple functions: it is a vantage point for observing the lunar surface, a communication hub (e.g., Polly uses it to shout instructions to Benoit), and a critical structural weak point. Hobson and Benoit seal a breach in the dome with a lab coat, while pressure gauges monitor the dome's integrity. The dome also houses a telescope for scanning external threats, such as Cybermen tunneling and antenna sabotage, and is used by Hobson and the Doctor to observe these threats.
