This classic adventure story begins when the Baltimore Gun Club, a group of brilliant but bored American weapons experts after the Civil War, decides to build a giant cannon to shoot a projectile to the Moon! Three brave explorers—Michel Ardan, Barbicane, and Captain Nicholl—volunteer to ride inside a special capsule. The book follows their incredible journey from planning and building to the thrilling launch, imagining what space travel might be like long before it was possible.
