Space exploration — A long dream

Going into space was always one of the biggest dreams people had, even thousands of years ago. Many science fiction authors wrote about traveling in space even before the first airplane flight in 1903. One of the most famous science fiction books on space travel is From the Earth to the Moon by Jules Verne — it was written in 1865, more than one hundred years before the first person walked on the moon. Jules Verne's idea was to use a giant cannon! That might seem silly today, but it shows how much our ideas on space travel have changed.
