Source plot synopsis — includes the ending
An old enemy of Barbicane, a Captain Nicholl of Philadelphia, designer of plate armor, declares that the entire enterprise is absurd and makes a series of bets with Barbicane, each of them of increasing amount, over the impossibility of such a feat.
The first obstacle, enough money to construct the giant cannon (and against which Nicholl has bet $1,000), is raised from a number of countries in America and Europe. Notably, the U.S. donates four million dollars, whilst England, at first, does not give anything. In the end, nearly five and a half million dollars are raised, which ensures the financial feasibility of the project.
Stone's Hill in "Tampa Town", Florida is chosen as the site for the cannon's construction. The Gun Club travels there and begins construction of the Columbiad cannon, which requires the excavation of a 900-foot-deep (270 m) and 60-foot-wide (18 m) circular hole, which is completed in the nick of time, but a surprise awaits Barbicane: Michel Ardan, a French adventurer, plans to travel to the Moon aboard the projectile.
During a meeting between Ardan, the Gun Club, and the inhabitants of Florida, Nicholl appears and challenges Barbicane to a duel. The duel is stopped when Ardan—having been warned by J. T. Maston, secretary of the Gun Club—meets the rivals in the forest where they have agreed to duel. Meanwhile, Barbicane finds the solution to the problem of surviving the incredible acceleration that the explosion would cause. Ardan suggests that Barbicane and Nicholl travel with him in the projectile, and his proposition is accepted.
In the end, the projectile is successfully launched, but the destinies of the three astronauts are left inconclusive. The sequel, Around the Moon, deals with what happens to the three men during their voyage from the Earth to the Moon.
