Episode Title:Explorers on the Moon Part 1.Episode Description:Professor Calculus, Tintin, Snowy, Captain Haddock, and Calculus's assistant Frank Wolff are aboard an atomic rocket-powered spacecraft leaving the Earth bound for the Moon. Soon after takeoff they discover that the detectives Thomson and Thompson have accidentally stowed away on board, putting a strain on the oxygen supply. The detectives accidentally turn off the nuclear motor, disrupting the artificial gravity and sending everyone floating until Tintin corrects the problem. They then suffer a relapse of the Formula 14 drug (seen in Land of Black Gold), resulting in their hair growing rapidly in multiple colours, until Calculus subsequently administers a cure. Haddock, who has smuggled whisky aboard the rocket, gets drunk and takes an impromptu spacewalk, during which he briefly becomes a satellite of the asteroid Adonis, but Tintin is able to rescue him.
