* (1909) was one of the first novels to include a spacecraft explicitly powered by nuclear energy, even if the details were a little vague. This can’t be said of the Flying Ring in The Moon-Maker , a novel published in 1915 by Robert Wood and Arthur Train. It is propelled on a mission to intercept an asteroid by a beam of alpha particles produced by the disintegration of uranium. (Not only were the authors the first ever to suggest the potential danger of an asteroid collision with the Earth, and to suggest a solution identical to those being proposed today, they included one of the first female astronauts in literature, the amazing Rhoda Gibbs.)
With the dawn of the new century, the spaceship as we know it today had been fully developed in the fiction of the age.
IV The Experimenters
The problem of spaceflight gradually evolved away from the purely speculative and theoretical. A more or less developmental approach was undertaken by those interested in the possibilities of spaceflight, though this approach was in many ways dictated as much by necessity as by intent. It was far simpler, cheaper and safer to experiment with small-scale rockets than with full-size spaceships; it was realized very early on that the exploration of space would be a fabulously expensive and difficult proposition.
In 1903 Tsiolkovsky published the first of his spacecraft designs; it employed liquid fuel and gyroscopic stabilization. In outward appearance his spaceship laid the groundwork for the modern spaceship to come.
Between 1913 and 1916, Andre Mas, Drouet and Henri de Graffigny devised schemes for centrifugally launched spacecraft, thrown from the rims of rapidly-spinning flywheels. Arthur Train and Robert Wood described the Flying Ring, a 66-foot-diameter torus propelled by an atomic motor suspended in gimbals from the apex of a tripod over the center of the doughnut-shaped ship. The fuel was uranium, producing a beam of alpha particles as it disintegrated.
The year 1923 saw the publication of Hermann Oberth’s seminal Die Rakete zu den Planetenräumen (The Rocket in Planetary Space), one of the theoreticial cornerstones of modern spaceflight. In it he first proposed his “Model E,” an enormous manned rocket that finally settled the outward form of the classic spaceship. It was an artillery-shell-shaped hull 100 feet tall and 30 feet in diameter that stood erect on the tips of four big fins. Oberth later elaborated upon the design in the 1929 revised edition of his book, Wege zur Raumschiffahrt (Ways to Spaceflight). In it he described a fictional circumlunar flight by the Model E spaceship Luna (on June 14, 1932). It was a three-stage rocket launched from the Indian Ocean. The pilots were ensconced in a small cabin shaped like an oblate spheroid, contained in the nose of the third stage. This was equipped with a parachute for the final descent to the Earth. Oberth, with his typical meticulous care, considered every detail: how his crew were to eat in free fall, waste disposal, heating and cooling, etc.
Oberth’s Model E formed the basis for the design of the spaceship Friede, which he provided for Fritz Lang’s 1929 motion picture Frau im Mond, the first realistic spaceship in movie history.
At about this same time rocketry pioneer Max Valier was actively publishing his own designs for spacecraft. A hyperactive proselytizer of space flight, he lectured all over Europe while his magazine articles were republished in every language all over the world. His influence over the popular conception of space travel was equaled only by that of Wernher von Braun in the 1950s.
Although Valier evolved his spaceship from existing aircraft—they even took off more or less horizontally from inclined ramps—the final design was aesthetically more pleasing than Oberth’s rather ultrafunctional rockets. Valier’s final design was a chunky streamlined spindle with curved fins at the rear and two outrigger nacelles containing the rocket
