The latter is one of the earliest depictions of space travel in popular fiction, featuring a capsule shot out of a cannon. It seems absurd by modern standards, but there's a hint of solid science underneath the fiction.
Set a few years after the resolution of the American Civil War, the novel centers on the disaffected members of the Baltimore Gun Club. The men are bored and restless; there are no new artillery weapons to construct and test, nothing left to blow to smithereens.
So their leader, Impey Barbicane (!), proposes they build a gigantic cannon to fire a projectile to the moon. Ultimately the plucky Gun Club succeeds in launching not just a projectile, but three men into space.
