Thunderbirds Are Go! S01E03 - Space Race

Alan is on "space junk duty" but things take a turn for the dangerous when one of the pieces of debris he attempts to clear away, turns out to be a heat-seeking SAT-MINE that activates and locks onto Thunderbird 3's heat signature. While Alan is forced to keep the mine locked onto his craft to safeguard other ships in orbit, Lady Penelope and Parker attempt to sneak into a top-secret storage facility and find the final digit to the mine's deactivation code, having only thirty minutes until the mine's nuclear charge detonates.
