On a marché sur la Lune
Hergé's use of research would include months of preparation for Tintin's voyage to the moon in the two-part storyline spread across "Destination Moon" and "Explorers on the Moon". His research for the storyline was noted in "New Scientist": "The considerable research undertaken by Hergé enabled him to come very close to the type of space suit that would be used in future Moon exploration, although his portrayal of the type of rocket that was actually used was a long way off the mark". The moon rocket is based on the German V-2 rockets.
