In 1961, very few had an idea of how humans might travel to and land on the Moon and return safely to Earth. But many had envisioned such attempts. Johannes Kepler, who in the 17th century, calculated the true elliptical orbits of the planets, also wrote “Somnium,” the dream, where aerial demons carry a voyager to the Moon. Many consider his story to be the first work of science fiction. Around the same time, Cyrano de Bergerac’s “Voyage dans la Lune” launches a traveler toward the Moon by fireworks. Even Edgar Allan Poe got into the lunar fiction act with "The Unparalleled Adventure of One Hans Pfaall," where his hero constructs a giant balloon to journey to the Moon.
