After Wilbur and Orville Wright's amazing breakthroughs, aviation technology - including the development of rockets, passenger planes, and supersonic experimental planes - moved quickly forward.
In 1919 Robert Goddard, an American rocket pioneer, imagined a rocket that could reach the moon. Goddard's dream was realized exactly 50 years later when an American spacecraft, sent into orbit by a huge rocket, reached the moon. But the half-century between Goddard's belief and Neil Armstrong's first steps on the moon was filled with lots of disappointments and failures, not just huge accomplishments.
One of Goddard's most important achievements was his belief that rockets had to be fueled with liquid, not solid (like gunpowder) fuel. After working on the concept for seventeen years, Goddard launched the first liquid fuel rocket on March 16, 1926. Although primitive (the rocket was at the top where it received fuel from two lines connected to the fuel tank at the bottom), it was a stunning conceptual achievement as important to space travel as the Wright brothers' work was to aviation. The rocket traveled 152 feet - about 32 feet more than Orville Wright's first powered flight in 1903.
It was also Dr. Goddard who first envisioned that rockets require several stages. He received a patent in 1914 for the concept that is an indispensable part of space travel today. The list of firsts created by this modest man is awe-inspiring. Some of his 214 patents still produce royalties for his estate.
But Goddard's work was not embraced in his own country. Ridiculed by the American press for thinking - and writing - that a rocket could go through the vacuum of space, his published work was read and admired the year after his death (in 1945) by Wernher von Braun. Goddard, the pioneer, had in fact anticipated the awesome power of von Braun's German A4 rocket (known to a stunned world as the mighty V-2). When von Braun's team launched the A4 on October 3, 1942, it traveled 120 miles and landed on target.
As the first successful ballistic rocket, the A4 is the ancestor of most rockets flown today. Looking back, one could make an argument that October 3, 1942 was the beginning of the space age. One could also make an argument it was the beginning of the age of mass destruction. Known as the V-2, von Braun's A4 became a huge military weapon for the Nazis near the end of the war. Launched from Germany (or German-controlled territories), it killed and injured thousands of people and decimated towns in Belgium (the link depicts death in Antwerp), the south of England, and elsewhere.
As World War II was ending, von Braun and his team of more than a hundred scientists turned themselves over to the Americans. It was the best thing that could have happened for the American space program.
