RESEARCH IN MASSACHUSETTS

In 1908 Goddard began a long association with Clark University, Worcester, where he earned his doctorate, taught physics, and carried out rocket experiments. In his small laboratory there, he was the first to prove that thrust and consequent propulsion can take place in a vacuum, needing no air to push against. He was the first to explore mathematically the ratios of energy and thrust per weight of various fuels, including liquid oxygen and liquid hydrogen. He was also the first to develop a rocket motor using liquid fuels (liquid oxygen and gasoline), as used in the German V-2 rocket weapon 15 years later. In a small structure adjoining his laboratory, a liquid-propelled rocket in a static test in 1925 “operated satisfactorily and lifted its own weight,” he wrote. On March 16, 1926, the world’s first flight of a liquid-propelled rocket engine took place on his aunt Effie’s farm in Auburn, Massachusetts, achieving a brief liftoff.

As is frequently the case with scientific theory and invention, developments proceeded in various parts of the world. In achieving lift-off of his small but sophisticated rocket engine, Goddard carried his experiments further than did the Russian and German space pioneers of the day. While Goddard was engaged in building models of a space-bound vehicle, he was unaware that an obscure schoolteacher in a remote village of Russia was equally fascinated by the potential for space flight. In 1903 Konstantin E. Tsiolkovsky wrote “Investigations of Space by Means of Rockets,” which many years later was hailed by the Soviet Union as the forerunner of space flight. The other member of the pioneer space trio—Hermann Oberth of Germany—published his space–flight treatise, Die Rakete zu den Planetenräumen, in 1923, four years after the appearance of Goddard’s early monograph.

Goddard’s early tests and others were modestly financed over a period of several years by the Smithsonian Institution, whose secretary, Charles G. Abbot, had responded to Goddard’s appeal for financial support. In 1929, following an aborted and noisy flight test that brought unwanted press notice to the publicity-shy inventor, Charles A. Lindbergh was instrumental in procuring greater financial assistance for Goddard’s experiments. From 1930 to the mid-1940s, the Guggenheim Fund for the Promotion of Aeronautics financed the work on a scale that made possible a small shop and crew and experimental flights in the open spaces of the American southwest, at Roswell, N.M. There, Goddard spent most of his remaining days in the unending trial-and-error reach for high altitudes.
