The fourth episode of the BBC’s short-lived science fiction series Moonbase 3 premieres. Garrick Hagon (Star Wars) guest stars. 
Talk of massive cuts to Moonbase 3’s budget loom, as does a visit from Dr. Hauser, a member of the Moonbase’s Earthbound appropriations committee. Caulder ramps up the pressure on his resident researchers to come up with a breakthrough – any breakthrough – to impress Hauser and save the Moonbase’s funding. One scientist is on the cusp of just such a major discovery, as he tries to perfect a process by which an incredibly strong but lightweight metal, normally something which can only be formed in microgravity, can be replicated under Earth’s gravity. Another scientist’s experiments into a new energy source are promising, but inconclusive. Both of them already feel isolated from the small community manning Moonbase 3, and the pressure to produce a major breakthrough manifests itself differently in each of them. The metal experiment produces a resounding success before Hauser’s eyes, but Caulder is surprised to see a major breakthrough in the energy experiments as well – but when he discovers that the seemingly successful experiment was faked, he has to decide whether or not to keep that a secret from Hauser.
