The third person on the projectile. Although he was once Barbicane's sworn enemy, he shook hands with his rival due to his passion for the space destination and joined this deadly journey. He has a major share in the team's engineering, calculation, and navigation checks. He knows mathematical terms like the back of his hand; he is an extremely orderly, rigid, yet cool-headed officer. He speaks with a logic appropriate to the seriousness of the situation and always refutes Ardan's dreamer arguments within mathematical boundaries.
He is one of the masters of armor science (while Barbicane is the master of cannons/propulsion systems). He had previously fiercely criticized the Gun Club's project and bet money that the projectile would not be able to leave the atmosphere. However, he is honorable enough to have taken a place in the projectile himself to see the truth.
Like Barbicane, he has serious and cold facial features; his military background is felt in his posture.
Michel Ardan
He has learned to tolerate his literary nonsense and has even come to enjoy this distinct aspect of his character.
Impey Barbicane
The old, massive hostility has given way to deep respect and a shared compatibility of mind.
