Science has progressed to amazing levels over the past century. Mankind has gone from exploring the oceans to exploring the near reaches of space. Many spacecraft are inefficient and short-lived due to their constituent engines. The introduction of the electric ion drive (ion thruster) recently has helped accelerate development and information gathering in space. The first to even publish the idea of electric propulsion was the Russian scientist Konstantin Tsiolkovsky in 1911. There are notes, however, to indicate that the man Robert Goddard first proposed the idea in 1906. Early experimentation took place at Clark University by Goddard himself around 1916. Years later, in 1959, a functional electrical ion thruster was produced by Harold Kaufman at the NASA Glenn Research Center. This engine was tested in 1964 aboard the SERT 1 (Space Electric Rocket Test 1), while successfully maintaining operation for thirty-one minutes. (“Ion Thruster”) Ion drive technology has greatly improved since then, and can be found in the majority of commercial satellites orbiting the planet today. Many spacecraft and satellites still use conventional liquid or solid-fuel rocket practices. While conventional rocketry has it’s upsides, it has no major place in the field of future space exploration. Ion drive spacecraft engines are the best for today’s space exploration because they are simple, safer to use, and very efficient.
Simplicity is one of the many upsides of an electric ion thruster. All ion drives vary in design and function, but the underlying physics that allow the system to actuate is almost identical for all. Many particles located in the universe have charges. An important particle is known as an electron. Electrons have negative ch...

...ets. Noble gases are also not as toxic as other elements available as fuel. A good example of this is helium; many people find amusement in breathing in helium to create a higher voice due to the speed of sound in helium, or conversely, a heavier noble gas to create a deeper voice. If a storage tank began to leak on a spacecraft, it is safer than if combustible fuel starts to drift into the cabin. Ion drives are also more controllable than conventional thrusters, therefore safer. If errors begin to persist or become evident during flight, it is harder to shut down a chemical rocket than an ion drive; an ion thruster only needs to have the power shut off to be disabled. Power generation for an ion drive is simple and safe as well. Electric current can be produced in a variety of ways, with solar generation being the most abundant currently. Larger ion systems require
MagLev technology is entirely different from any form of transportation in operation today, but the basic principles that lie at the foundation are not beyond the understanding of the beginning electricity and magnetism student. It is in the application of these principles to design and optimize an actual train that things get hairy. The basic idea has been researched since the mid-sixties, but it is only now that economically feasible prototypes are being built and governments are seriously looking towards magnets to propel us into the next century. Leading the race is Germany. Their design, the Transrapid 07, is ready for commercial production. It utilizes conventional electromagnets and forces of attraction to levitate the train. A good web site to find out more about German plans for their design is http://transrapid.simplenet.com/index-e.htm
With respect to the rocket program, the A1 rocket was first completed at the end of 1933. It was only 5 feet long and powered by an alcohol and liquid oxygen motor. Gener...

Therefore, the initial excitement for space-nuclear power sources was quickly ended by uncertain requirements, and the broad range of more feasible technical approaches was researched.
...ion is not an easy one to refute, though I believe that rather than disallowing all exotic thought experiments we should perhaps judge the suitability of each individual scenario on its own merits. This appears to be a more achievable task.
We as humans have always been fascinated with the unknown.� We seek to conquer every frontier.� Today, the final frontier is space.� So, many people are very interested in rockets, the vehicle for conquering the final frontier.� Most people have a general idea of how rockets work, but very few have an understanding of the physics behind their flight, which scientists spent many years perfecting.
A mechanism by which a self sustaining structure generates an attraction field is described, together with the mechanism by which multiple structures interact. The process relating to interaction within a single structure is also described. The paper examines the nature of the gravitational field. It follows from the prognosis that the atomic particles identified so far from accelerators, are formed by a quanta/energy degradation which takes place. The core exists as a single entity in an electron, this same particle forming an assembly in all the structures identified in the periodic table.
Rocketry, the use of rocket power as a propulsion mechanism, has changed the boundaries of man’s domain.Before the advent of efficient rocket power, space flight was seen as an impossibility and exclusively the subject of science fiction stories.The nature of rocket power changed in the early twentieth century when a man named Robert Hutchings Goddard focused his research and his entire life on efficient rocket propulsion.Rocket power had been thought of long before Goddard’s time, but he was the first to have success with it.
From early childhood rockets, a V-2 rocket, and America’s first orbital satellite, Wernher von Braun’s life inventions really made an impact on history after the completion and success of the Saturn V “moon rocket” that carried man to space and then eventually to the moon with a various string of Apollo Missions. There would be an outstanding amount of components both electrical and mechanical that would be needed to bring together a dream that von Braun had long sought for. This dream invention of his would focus on carrying three astronauts, be comprised of 3 rocket booster stages, lifted initially by the thrust of five F-1 rocket engines, and need a number of things to happen in sequence.
The Space Race was the competition between two Cold War rivals, the Soviet Union (USSR) and the United States (US), for supremacy of space travel and exploration. The content of Civil War was continuously taught at school since elementary. Through our past experiences and learning, my partner and I are greatly informed in this area of history which making it as an advantage for us. In addition, my partner have visited the NASA convention center where she gathered additional information to develop this project. It was a great experience for her to actually see all the technologies that were used during that period and ask questions about the future innovations. We chose this topic not just because of our passion and reliable sources for the topic but how it relates to the theme, Exploration, Encounter, and Exchange in History. Through the Space race, it led
Although Wernher Von Braun hated math and science as a child in school, he pushed his teachers. Studying, and nights of hard labor and research led to the greatest space exploration program in all of mankind. Von Braun was awarded with many medals, certificates, and trophies. He launched satellites and astronauts into space, and to the moon. He led over 4,000 scientists to NASA and controlled the space flight center for over 10 years. America’s asset, Wernher Von Braun was a clever, revolutionary man that not only sent our men to the moon, but kick started the entire space exploration program.
Types of rockets in the world can include The Ion rocket and a Small Satellite. The Ion rockets use solar cells to make electrical energy into thrust. The Ion rocket can not carry any chemicals on a mission. It is used for pushing satellites into the right position. There are Small satellites that can fly around the earth’s wide range of orbit. It has low thrust being that it does not need much to orbit Earth and the cost is very low. The Small satellites do not do much other than orbit Earth and help bring signals to Earth. So, the Ion rocket is better for long distance and pushing weight while The Small satellites just
Generally when people think of monsters all they think about are some scaly, or hairy, or just big some big scary monster. But actually spending some time with said monsters start to discover a bigger meaning of these monsters. You see a monsters isn't just made off the top of someones head it is actually thought about like what features it will include. For example the makers of horror film monsters have to think about things like what audience are they making this monster for or what kind of features will the monster have to have to scare this audience.
Before learning about the space explorations and all those courageous astronauts, it is crucial to know the genius masterminds of the explorations. Sergei Korolev was the chief Soviet designer and former political prisoner. His budget was small, yet he accomplished so much (Cadbury 129). Of course, his rival is Wernher von Braun, America’s much loved leader of the rocket team. After WWII, von Braun came to America. Few people knew this, but he was an SS officer and member of the Nazi party (Roger 236). Nevertheless, even though von Braun had a horrific past, he developed many launch vehicles for the U.S.
