"Schritte auf dem Mond" ("Explorers on the Moon," 1954) picks up right where "Reiseziel Mond" ("Destination Moon") left off, with Tintin and his friends unconscious in a rocket hurtling for the moon and everybody back at the Sprodj Atomic Research Center in Syldavia worried sick about them. No surprise, they wake up and land on the moon (otherwise the title does not make any sense). Ultimately, what makes "Schritte auf dem Mond" so fascinating is the documentary detail that Hergé infuses into the story. I cannot think of a 1950s science fiction film made during this same period that predicts as accurately what happened when Apollo 11 went to the moon a decade and a half later (and I thnk have seen just about all of those black & white science fiction films from the Fifties).
One of the chief charms of Hergé's artwork has always been the way his caricature drawings of Tintin and friends are contrasted by the realistic backgrounds, and this artistic style achieves its apex when we see the spaceship approaching the moon. "Schritte auf dem Mond" would work as a straight-forward first man on the moon type story, but, of course, in Hergé's capable hands it becomes so much more. Taken together with "Reiseziel Mond," these are one of Tintin's greatest adventure. After all, what greater height can our intrepid reporter, Struppi, Captain Haddock, Professor Beinlein, and Schulze and Schultze reach than the Mond?
