The launch of Verne's craft was preceded by an actual by-the-second countdown using an accurate electric clock; its mass, approximately 10,000 kg. was very close to the actual mass of the Apollo command module. Verne's capsule also had three astronauts on board (two of them American and one Frenchman, in the spirit of international cooperation); it used a chemical system to generate oxygen and another to extract carbon dioxide during the trip and it made a slingshot trip (named Free Return Trajectory a century later) around the Moon in order to return to the Earth.
"Around the World in 80 days" must have encouraged many people in the last century to travel internationally. Even today, it can be a challenge to achieve Jules Verne's journey in his time limit.
"Journey to the Centre of the Earth" tells how a group of people tried to discover the secrets inside the Earth's core.
