the first story to be based on scientific principles – science fiction. There had been earlier stories about interplanetary travel. Perhaps the earliest known story was written during the Second Century AD. It was the “True History” by Lucian of Samos. At that time it was widely thought that the earth was the centre of the universe (the Geocentric theory). After Lucian, stories about interplanetary travel were neglected until the invention of the telescope.
The telescope was invented in the Netherlands in 1608 but was made famous by Galileo Galilei. The original design was easy to copy. It was a three-powered instrument that magnified the image three times. Galileo constructed his own instruments, making them increasingly more powerful. Using a twenty-powered instrument he observed the Moon, discovered four satellites of Jupiter, and resolved nebular patches into stars. He published his findings as
The astronomer Johannes Kepler (1571–1630) was the first man to discover the exact laws governing the movements of the planets – principles which apply to the movements of spacecraft. Kepler also wrote a story about interplanetary travel which was published in 1634, after his death. In Kepler’s story,

An earlier work of science fiction had featured a spacecraft powered by a form of rocket propulsion, like a ram jet. In 1656 Cyrano de Bergerac wrote
H.G. Wells’s contribution was less scientific but more readable than earlier interplanetary stories. His
The concept of an anti-gravity substance originated with J. Atterley, whose
Wells’ book was followed by numerous works that referred to interplanetary flight. In 1951, the science fiction writer Arthur C. Clarke attributed the increase in the number of books on this subject to two causes: in the first case, the conquest of the air had acted as a stimulus to imagination; in the second, the foundations of astronautics were being laid by competent scientists, and the result of their work was slowly filtering through to the general public. The researches of Goddard (from 1914 onwards) and later of Oberth had focused attention onto the rocket, and even before the modern era of large-scale experimental work had confirmed the accuracy of these men’s predictions, the rocket had been accepted as the motive power for spaceships in the majority of stories of interplanetary travel. Numerous rocket scientists, including Goddard and Oberth, acknowledged the inspiration of the fiction of Verne and Wells.
In 1903 the Wright brothers made their first historic flight. In the same year, the Russian, Konstantin Eduardovich Tsiolkovsky (1857–1935) published his book,
Originally, Tsiolkovsky was a schoolteacher, but was so inspired by Jules Verne’s stories that he, too, tried to write science fiction. He soon introduced real technical problems into his tales of interplanetary travel, such as rocket control in moving into and out of gravitational fields. Before he wrote his book, Tsiolkovsky had actually evolved from fiction writer to scientist and theoretician.
German rocket scientists like Ernest Stuhlinger and Wernher von Braun were also inspired by a 1926 Fritz Lang film,
The prophets of fiction did not always get it right. In 1951 Arthur C. Clarke, himself, predicted that “orbital refuelling is the key to interplanetary flight.” The single-stage rocket which he anticipated might have needed this. But the next year Wernher von Braun was explaining the concept of the multiple-stage rocket.
A science fiction novel was later responsible for modifications to the US space program. An additional safety measure was added to the Gemini program, with Gemini III (1965) becoming the first manned Gemini mission, practising a maneuvre to act as a safety precaution. The point of the maneuvre was to avoid a scenario which had been envisaged in Martin Caidin’s novel
On Gemini III’s third orbit it completed a fail-safe plan and made a two and-a half-minute burn with its thrusters that reduced the spacecraft’s orbit to 72 kilometres to ensure re-entry even if the retrorockets failed to work.

On the recommendation of Clarke, Kubrick hired spacecraft consultants Frederick Ordway and Harry Lange as technical advisors on the film. Ordway and Lange had assisted some of the major contractors in the aerospace industry and NASA with the development of advanced space vehicle concepts. Ordway was able to convince dozens of aerospace giants such as IBM, Honeywell, Boeing, General Dynamics, Grumman, Bell Telephone and General Electric that participating in the production of

Gene Cernan, the commander of Apollo 17, the last manned mission to land on the Moon, agreed about the need for inspiration. He said that it is vital to “inspire young people to reach out further than they thought they could reach before”. “The inspiration of our young people is truly what the future is all about,” he said.
Science fiction has provided some of the terms by which we describe developments in space. In 1997, aboard the space station Mir, the astronaut Jerry Linenger wrote to his son: “Space is a frontier, and I’m out here
