What to read after From the Earth to the Moon and 'Round the Moon (月界旅行和環繞月球)?

From the Earth to the Moon (French: De la Terre à la Lune, 1865) is a humorous science fantasy novel by Jules Verne and is one of the earliest entries in that genre. It tells the story of the president of a post-American Civil War gun club in Baltimore, his rival, a Philadelphia maker of armor, and a Frenchman, who builds an enormous sky-facing Columbiad space gun and launch themselves in a projectile/spaceship from it to a Moon landing.The story is also notable in that Verne attempted to do some rough calculations as to the requirements for the cannon and, considering the comparative lack of any data on the subject at the time, some of his figures are surprisingly close to reality. 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.Includes a Biography of the Author
