Professor Calculus, Tintin, Tintin's dog Snowy, Captain Haddock, and Calculus' assistant Frank Wolff are aboard an atomic-powered rocket to 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 motor, disrupting the artificial gravity and sending everyone floating until Tintin corrects the problem. They then suffered a relapse of the Formula 14 drug (seen in Land of Black Gold), resulting in their hair to grow rapidly in multiple colours. Calculus administers a cure. Haddock, who has smuggled whisky on board the rocket, gets drunk and takes an impromptu spacewalk, during which he briefly becoming a satellite of the asteroid Adonis but Tintin is able to rescue him.
