Seed of Destruction

An ice-cold replica of Commander Koenig takes control of the moon -and orders its destruction.

Background

• Shooting script dated 25th May 1976. Filmed 7th July- around 23rd July 1976

SFX

The opticals from the firestorm in Catacombs Of The Moon are reused. The DVDs contain an interview from July 1976 with Brian Johnson, showing the storyboards and the setting up of one shot. The shot (scene 73, showing the Eagle from below illuminated green) is not in the final episode.

Music

Science

• The crystal asteroid is perhaps related to a white dwarf, where a small star has collapsed into an inert core of carbon and oxygen, about the size of the Earth but extremely dense. They are also extremely hot, although over time they cool into a black dwarf star. The carbon core of a white dwarf may be an enormous diamond. One variable white dwarf star, BPM 37093 is estimated to be 90% crystalised (of a mass 1.1 times that of the sun), making it the largest known diamond.
• The asteroid has Earth gravity and a "localised atmosphere", suggesting it is very dense. However, it seems unlikely the total power of Moonbase Alpha could regenerate an entire planet.
• The term "black sun" is used again. It is featured in the episode Black Sun and also mentioned in Dragon's Domain.

Continuity

Chronology:

1608 days after leaving Earth orbit (Sat 7 Feb 2004)

Alpha Personnel:

0 fatalities.

Alpha Technology: The fixed laser cannons are seen. They are also in The Metamorph, The Beta Cloud, Bringers Of Wonder part 1 and The Dorcons. The multi-function hatch is shown; here it fires the laser canon. There is a close-up shot of a computer panel clearly marked "Satellites".

Eagles:

Eagle 1 (Koenig, Tony)

• The forward view screen is seen. It is also seen in The A B Chrysalis, Seed Of Destruction, Space Warp, Bringers Of Wonder part 2, The Seance Spectre and Devil's Planet.

Maya transformations: lizard animal (as seen in The Beta Cloud), Cranston

Planets:

None (Kalthon asteroid)

Aliens:

Kalthon seed

Props:

Life Support Section is a minimally changed Weapons Section (among the red panels beyond are the "Life Support Systems Control" panels also seen in the Power Room in The Beta Cloud and Bringers Of Wonder part 1)

The first Moonbase window to be seen in Year 2. Note the gravity tower immediately outside. The dish is presumably the transmitter dish- although the model version does not have the number "3".

Errors

Koenig's Eagle has a booster pod when first seen, then a standard pod subsequently
	Koenig is in the Weapons Section when he calls Weapons.

Observations

The original script had an epilogue in which Koenig's crystal sample is projected into space. Martin Landau also played doppelgangers in the 1973 Columbo episode "Double Shock" (thanks to Chris Moore)

Unusually, Helena isn't wearing her long boots in this shot.
