The space crew of Tintin will soon leave the planet to firsthand experience the challenges of space missions. Communications, difficulty in maintaining course, and uninvited passengers will turn the monotony of space into an adventure for those with strong nerves.

While the moon landing seemed easy, the same cannot be said for the problems hidden in the rocket, in the form of Colonel Jorgen who, in collaboration with scientist Wolff, will fatally threaten the lives of Tintin's crew. But since the most beloved place in the world is Earth, as the captain says, Tintin will manage to get rid of all these dangers for good, and just in the nick of time.
