Robert Hutchings Goddard Essay

Robert Hutchings Goddard is an American rocketry pioneer; he is considered the father of modern rocket propulsion. In 1926, Goddard had constructed and successfully tested the first rocket that uses liquid fuel. The flight of Goddard’s rocket on March 16, 1926, at Auburn, Massachusetts, was as significant step to improving rockets. The first culture that started to experiment with rockets was the Chinese, the date reporting the first use of rockets was in 1232. The earliest rockets were used by the Chinese to defend their home from the Mongols by shooting a barrage of "arrows of flying fire.". They started to fill gunpowder into bamboo tubes, then they put the gunpowder filled tubes on arrows and began to launch them they eventually found that the gas can launch the arrows. When the

Hypergols are highly toxic and must be used with extreme care. Hypergolic fuels commonly include hydrazine, monomethyl hydrazine (MMH) and unsymmetrical dimethyl hydrazine (UDMH). Hydrazine gives the best performance as a rocket fuel for most situations. Rockets have improved greatly since the time of Robert Hutchings Goddard, now they are able to go further and faster than ever before. The SLS will be NASA’s first exploration-class vehicle that will take Astronauts to mars for the first time in history. It will expand our reach in the solar system, launching crews aboard the new Orion spacecraft to explore multiple, deep-space destinations including mars. A fleet of robotic spacecraft and rovers are already on and around Mars, but to fly to and land humans safely on Mars requires a next-generation spacecraft this is where the SLS will come into play too complete that job. This “Rockets” essay helped me learn about the science of how rockets work such as the propellants used and how newton’s laws of motion affect rockets. Researching rockets led to mea learning about the culture of rockets and how they were first invented and used by the Chinese against the Mongols to defend their
