Goddard, who successfully launches the world’s first liquid-fueled rocket at Auburn, Massachusetts, on March 16, 1926. The rocket traveled for 2.5 seconds at a speed of about 60 mph, reaching an altitude of 41 feet and landing 184 feet away. The rocket was 10 feet tall, constructed out of thin pipes, and was fueled by liquid oxygen and gasoline.

The Chinese developed the first military rockets in the early 13th century using gunpowder and probably built firework rockets at an earlier date. Gunpowder-propelled military rockets appeared in Europe sometime in the 13th century, and in the 19th century British engineers made several important advances in early rocket science. In 1903, an obscure Russian inventor named Konstantin E. Tsiolkovsky published a treatise on the theoretical problems of using rocket engines in space, but it was not until Robert Goddard’s work in the 1920 s that anyone began to build the modern, liquid-fueled type of rocket that by the early 1960 s would be launching humans into space.
