Rockets were first introduced in 1232 AD. Therefore, they have a very long and extensive history. At first, rockets were just used as weapons, but as early as 1806 they began being used for space travel. The first rockets that were made, were made in China. This was during the time that black powder was discovered. Several years later the largest rocket in the world was built which took 18 months to finish. Many of us don’t think of all the work that has been put into creating rockets. From the tiny weapons that were used to fight off enemies, to the 300 foot tall contraption that sends people to space, rockets have forever changed history and the way that space travel has developed. A rocket is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellants carried within the rocket before use. Rockets are powered by engines, and engines work by action and reaction. Pushing the rocket forward and then throwing the exhaust backwards causes the rocket to go into the air extremely fast. While comparatively inefficient for low speed use, rockets are relatively lightweight and powerful, capable of generating large accelerations and of attaining extremely high speeds with reasonable efficiency. Rockets are not reliant on the atmosphere and work very well in space. Unlike ordinary engines, rockets carry their own supply of oxygen to burn its fuel. As rockets have gotten bigger and bigger so have the engines. The largest rocket in the world which took 18 months to build was NASA’s Saturn V model. Werner von Braun designed this rocket. He developed a rocket that got the first group of men to the moon in July of 1969. The technology of rockets was first k... ... middle of paper ... ... influenced by the Mongol invasions of the previous few centuries. Chemical rockets are the most common type of rocket and they typically create their exhaust by the combustion of rocket propellant. Chemical rockets store a large amount of energy in an easily released form, and can be very dangerous. However, careful design, testing, construction and use minimize risks. In space, there are better ways of propulsion. Many of them get much more mileage, but they are slower and require an electric power source. Once we start to industrialize space, we will surely assemble large "space trucks" in low Earth orbit to haul payloads around space much more efficiently, using something else besides chemical rocketry. However, for people, who need to be transported quickly, we can assume we will be using chemical rocketry in the first stage of large scale space development.
During the late 1950’s the space race began. This was a race to see who could achieve the most space firsts, between the USA and Russia. Sonny, O’Dell, Sherman, Roy Lee and Quentin live in Coalwood, West Virginia.The space race inspired these boys, who decide to call themselves the Rocket Boys, to make their own rockets. The BCMA (Big Creek Missile Agency) was born when Sonny called a meeting with his friends in his room and discussed how he wanted to build rockets. With the help from the a man at the town’s machine shop, Mr.Bykovski, the BCMA built its first rocket, called Auk I. The rocket was named after an extinct bird that was unable to fly. Auk I was equipped with a wooden bullet shaped nose cone, an aluminum tubing body, fins, and a soldered washer at the bottom. The boys mixed together black powder and postage stamp glue to act as fuel for their rocket. The rocket flew up 6ft, and then fell back down. The rocket boys later found out that the reason their rocket stopped flying was because the solder melted. The BCMA was happy with the result from the rocket, because it was their first ever rocket to fly.
Cost management plays a major role when maintaining profit margins. Management must be able to find in which areas of a business costs must be reduced and the consequences that such reductions have in the overall company. In some situations management must change the way the work is being done in order to decrease costs while in other cases changing one supplier for another might be enough, in both situations a tradeoff will occur and the consequences will impact the company as a whole.
"One small step for man, one giant leap for mankind," said by Neil Armstrong as he took his first steps on the moon during the NASA Apollo 11 expedition to the moon. No man has ever been to the moon before and NASA, The National Aeronautics and Space Administration, was the first to get someone to land on the moon. NASA has had many great accomplishments in exploring the "new frontier" that have affected the United States ever since it was first created in July 1958. The idea for NASA first started when the Soviet Union launched the first satellite on October 4, 1957. United States started up its own space travel program and started to work on its own projects that would be better in than the Soviet Union's. This all started the great space race. It was a big race between the Soviet Union and the United States to see who could learn and discover the most. The United States and Soviet Union started building and sending satellites and space ships. Then they tried to see who could make a suit and ship that would be able to allow a living thing to go up in space. They tested out all of the equipment with monkeys and dogs, seeing what would work. Many animals did die in the process but by the results of their testing they were able to build suits and ships that allow human beings to go up in space. Even though they were able to create these machines, that doesn't mean that they didn't have their difficulties and dangers. Two space shuttles were crashed or blown up. There were many key factors that they had learned to fix that resulted in the crashing of those ships. They have made many discoveries and accomplishments like having the first astronauts walk on the moon.
A shuttle is the size of a jetliner, lifts into space using powerful boosters, and returns to Earth as a glider due to its aerodynamic wings. Launching like a rocket, it orbits the earth like a spacecraft and lands like an airplane ("Shuttle Basics," par. 1). It takes eight and a half minutes for the shuttle to reach space, it travels at 17,500 miles per hour, and the crew can see the sunrise or sunset every 45 minutes ("Space Shuttle Program," par. 3). The shuttle consists three main parts: the Orbiter Vehicle, two Solid Rocket Boosters, and the External Tank.
This blow to national pride along with the fear that the Soviets could potentially launch ICBMs from space led to “Rocket fever”. The sudden wave of nationalism and the desire to build a space program worthier to that of the Soviet Union led to the establishment of the National Aeronautics and Space Administration (NASA) under President Eisenhower, the investment of billions of dollars in missile development, and the expansion of the National Academy of Science’s charter.... ... middle of paper ... ...
The Soviets took a lead by launching the first successful satellite into space. On October 4, 1957 the Soviets launched the first successful satellite into orbit. It was called Sputnik I and it successfully entered Earth’s orbit. This first success started the Space Age. The Soviets successful launch shocked the whole world, giving the Soviet Union the respect for putting the first man-made object into outer space. The Americans successfully launched their first satellite four months after Sputnik I, called the Explorer I. The US would have had the first satellite in orbit if they were allowed to use military rockets from the beginning. But, Eisenhower was worried he would be called a warmonger if he used military rockets for launching a satellite into orbit. He told the sci...
Space exploration has changed and developed since the first man was sent into space. Advanced rockets, new computer technology, and remote controlled robots are only a few of the things that made space travel possible. Even though this technology was efficient, it was not cheap. When a rocket was sent into space, only the capsule holding the astronauts returned to space. This expensive way of space travel was forever changed with the creation of the space shuttle. The Columbia space shuttle was important to space exploration because it used new technology that changed space travel, completed missions that other spacecraft could not, and brought new people into space.
The first solid fuel rocket was invented in 1805. Ever since then rockets have made a huge impact not only in the scientific world but also in everyday life. To build a model rocket and to get it to launch into the air succesfully does not involve much rocket science, but it does involve chemical reactions. Without a heart we wouldn’t be able to live, as with a rocket without an engine it would not be able to be a full rocket. To successfully make an engine to your rocket that will allow it to launch into the air and land you must use chemical reactions to generate a well built engine.
On May 25, 1961, just two weeks after the US had successfully got an American into space, John F. Kennedy gave a speech addressing it and exclaimed, "I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project...will be more exciting, or more impressive to mankind, or more important...and none will be so difficult or expensive to accomplish..." (Kruse). The Space Race became an important event for all of humanity during the 20th century because it improved our knowledge of space, improved and inspired new technology, and improved our education. It sparked a mix of both friendly and non friendly competition between the Capitalist United States and the Communist Russia (USSR) from the launch of Sputnik in 1957, all the way to the Apollo-Soyuz project that ended the race in 1975 .
Space travel was born from the flames of war – or in this case, the refrigerators of war. The Soviet Union and the United States were ready to show up each other in the fields of science and engineering, and with the recent advent of rocketry, it was evident that space was the next goal. Russia held the first few victories: including the first man-made satellite and the first man in space. Following these defeats, America picked itself up, and defeated the Russians on the race to the moon.
Although the two countries never said that The Space Race was a competition, everyone knew it was because the two countries were already competing for weapons. The Soviets “won” the first “round” by shooting an item into space, Sputnik 1; this became the first human made satellite to be launched into space. This accomplishment had triggered the Space Race. About four months later, Wernher von Braun, a German engineer and space architect, and the US launched their first satellite, known as Juno 1. Wernher von Braun was said to be the “Father of Rocket Science”. Although Von Braun was a Nazis, he was allowed protection and entrance into America.
Long ago rockets were used to launch fire crackers into the air in china, now they are used to travel beyond the stars. Rockets became bigger and much more manageable which instantly made them beneficial to U.S. and the Soviet Union’s space race. The Soviet Union was the first to orbit around the world while the U.S was the first to put a man on the moon. After World War II rockets were also used specifically for launching satellites in orbit, because of this we now have gps, we can predict when the weather changes, when storms are coming, make international calls, for the most part, even use our cell phones. The final technological change of the 20th century are atomic weapons. During World War II the atomic bomb that was dropped on Hiroshima proved to be lethal to everyone. Humans now had the ability to destroy an entire country by just the push of a button. Powerful countries like the U.S and the Soviet Union realized the deadly future ahead and made it their goal to never have another world war. Atomic science on the other hand led to a controversial process of producing energy called fission, which is now used to power submarines, electricity, and aircraft
Even in the late 19th century, few people believed such a feat was possible, and yet, a mere half a century later, the first man was launched into space (Irvine 5). How did the human race go from just dreaming about space to actually launching human beings into space in such a short time? Surprisingly, the United States’ space program started with the Cold War. The Cold War pushed the United States and the Soviet Union into a space race in which both nations rapidly developed space programs and tried to best each other in space exploration (Cold War 1). The Kennedy Space Center was built in Florida as a control center which handled many of the shuttle launches into space (NASA 1).
In the past 100 years, we have made much advancement in all areas of society. The way people live has changed drastically just in the past century. Technology in particular has advanced more in these last 100 years then all previous time combined. For example, because of the research done by many innovative and dedicated individuals such as the Wright Brothers who were the first to sustain flight in a powered airplane, we are able to fly all over the world in a matter of hours in jet propelled pressurized aircraft. One hundred years ago, the thought of man flying in a machine was insane. The Wright Brothers helped to realize the dream of manned flight. Many years later, after the idea of manned flight becoming a reality, space exploration was the next step. In 1969, many people did not believe what happened. Neil Armstrong and Buzz Aldrin landed on the moon. They posted an American flag, explored, collected space rocks and came back home. Many Americans did not believe that the technology existed to go that far. Today, several missions a year are launched using manned space shuttles that can be flown back to earth like gliders and reused on future space missions.
There are many inventions of the future that people either know or hope will happen and some inventions that people have never thought that would happen in this or the next lifetime. For instance, one piece of future technology that I believe may come to pass is the invention of flying cars. Since the time of being young and watching the Jetsons, many people have been waiting to see the first flying car. While bringing up the idea of a flying car to a lot of people would seem absurd or downright impossible to some, I actually believe that it is very much so possible to create given how far technology has come in the past few decades. I think that it is a very logical conclusion to assume that at some point in the future engineers, car makers, and others will start to pursue other alternatives to avoiding traffic jams and other problems on the road, and instead begin to examine the possibilities of taking to the air as an alternative solution. There is much talk about it over the internet and many people would like to try flying cars. While it would greatly improve traffic for those that prefer staying on the ground, it may prove dangerous in the beginning because of accidents in the air with other cars, planes, trees, and buildings. Some would say though, that the convenience would outweigh the risks because there would not be traffic jams, or detours because of road work. These cars would need something like a GPS system and an anti-wrecking system so people would not run into each other or other objects (How Flying Cars Will Work).
