Relic.When a meteor shower is projected to hit the decommissioned Shadow Alpha One moon base, concern arises with the discovery the base is still inhabited by a lone crew member - Captain Lee Taylor, an old friend of Jeff Tracy. Scott and Alan take Thunderbird 3 on a rescue mission after attempts to warn him fail, but when Scott boards the base, he's surprised to find Taylor attempting to maintain its defence system against meteors. After initial attempts to defend the base against continuing waves of meteors start to fail, both Scott and Taylor are forced to abandon the base to meet Thunderbird 3 at a rendezvous on the moon's surface that is itself threatened by the meteor shower.
