From the Earth to the Moon（IV）地球到月球（英文版） (English Edition)

From the Earth to the Moon is an novel by Jules Verne in 1865 ．It tells the story of the Baltimore Gun Club, a post-American Civil War society of weapons enthusiasts, and their attempts to build an enormous Columbiad space gun and launch three people—the Gun Club's president, his Philadelphian armor-making rival, and a French poet—in a projectile with the goal of a moon landing. The story is also worthy of attention in that Verne attempted to do some rough calculations as to the requirements for the cannon and, considering the comparative lack of any empirical data on the subject at the time, some of his figures are remarkably accurate. However, his scenario turned out to be impractical for safe manned space travel since a much longer muzzle would have been required to reach escape velocity while limiting acceleration to survivable limits for the passengers.
