March 16, 1926 , Professor Robert Goddard, Massachusetts ( USA) for the first time, successfully launched a rocket powered by liquid fuel ; Robert Goddard: A Man and His Rocket On March 16, 1926, Robert Goddard successfully launched the first liquid-fueled rocket in Auburn, Mass. The first-of-its-kind rocket reached an altitude of 41 feet, lasted 2 seconds and averaged about 60 miles per hour. Dr. Goddard with one of his rockets Goddard wrote in his autobiography about an inspiration that came to him as a boy while up in a cherry tree pruning branches: I imagined how wonderful it would be to make some device which had even the possibility of ascending to Mars. I was a different boy when I descended the tree from when I ascended, for existence at last seemed very purposive. Image to right shows Dr. Robert H. Goddard (1882-1945) and his earlier rockets. He was the first scientist to realize the potential of missiles and space flight and contributed in bringing them to realization.

Clouds of smoke caused a lot of commotion and the faculty, rather than expel him, took an interest in his work. By 1914, Goddard already had received two U.S. patents: one for a rocket using liquid fuel and the other for a two- or three-stage rocket using solid fuel. Until that time, propulsion was provided by various types of gunpowder. Goddard began teaching physics in 1914 at Clark University in Worcester and was named director of the Physical Laboratory in 1923. His thoughts on space flight started to emerge in 1915, when he theorized that a rocket would work in a vacuum, and didnt need to push against air in order to fly. This meant that in the vacuum of space, rocket engines would be able to produce thrust. Goddards discoveries were given little attention by the U.S. government. A modest man, Goddard paid for the rocket experiments from his own paycheck. Funding from the Smithsonian Institution allowed Goddard to continue his rocket research and develop the mathematical theories of rocket propulsion. In 1920, the Smithsonian published his original paper, A Method for Reaching Extreme Altitudes, in which he included a small section stressing that rockets could be used to send payloads to the Moon. Unfortunately, the press got wind of this and the next day, the New York Times wrote a scathing editorial denouncing his theories as folly. Goddard was ridiculed and made to look like a fool. He responded to a reporters question by stating, Every vision is a joke until the first man accomplishes it; once realized, it becomes commonplace. New Mexico rocket launch In 1930, Goddard and a small crew of workers moved to New Mexico to continue his research in seclusion. Goddard died on Aug. 10, 1945, holding 214 patents in rocketry but having received little attention for his propulsion research. Image to left shows a launch in New Mexico. By the mid 1930s, Goddards rockets had broken the sound barrier at 741 mph and flown to heights of up to 1.7 miles.

Now known as the father of modern rocketry, Goddards significant achievements in rocket propulsion have contributed immensely to the scientific exploration of space. Goddard didnt live to see the age of space flight, but his foundation of rocket research became the fundamental principles of rocket propulsion. A day after Apollo 11 set off for the Moon, in July of 1969, the New York Times printed a correction to its 1920 editorial section, stating that it is now definitely established that a rocket can function in a vacuum as well as in an atmosphere. The Times regrets the error. NASAs Goddard Space Flight Center in Greenbelt, Md., a major space science laboratory, was named in his honor.
