Materials Of A Rocket Or Space Shuttle

Rockwell, the shuttle’s primary contractor, did not support the launch due to the possibility of ice leaving the structure and damaging the thermal shield tiles during takeoff. Their concerns were relayed to NASA, but in such a way that NASA chose to proceed with the launch [2]. Though this was eventually determined to be a non-issue in the Challenger launch, the true nature of the problems that can occur when an object strikes the shuttle during takeoff would not be learned until 2003, when the space shuttle Columbia disintegrated on re-entry due to damage of a heat shield tile that occurred during takeoff [2]--[3].

The National Aeronautics and Space Administration (NASA) is one of the leading organizations in space technology and research. In the past 60 years, NASA has sent numerous satellites, telescopes and crew modules into space. Despite drawbacks in launch failures and lack of funding, NASA continues to focus on its mission in space exploration and technological advancement. One of NASA’s projects is to explore deep space, in which entails a manned missions to Mars, exploration of the asteroid belt, and beyond. With these goals in mind, NASA has engineered new rocketry and even created a program to better allocate costs of such conquests. With these new advancements, NASA has created a new age of how space travel is carried out.

Neil Armstrong 's 1969 lunar landing was one of humanity 's greatest accomplishments. Since then, we have found that an infinite supply of knowledge and resources await us just outside our atmosphere. Today, however, critics are beginning to argue more and more that the cost of space exploration is too high, and therefore new technological developments should be left to the private sector. Whether funded privately or by the government, funding of space exploration is imperative because NASA is essentially the only agency with the technological capabilities to support aircraft manufacturing, air safety and air transportation. Space exploration has also resulted in remarkable innovations that has played a key role in aeronautics research, preventative medicine, and allows scientists to study asteroids, along with other space debris and their impacts on Earth.

America’s space program is undoubtedly one of its greatest modern achievements. Few people cannot recall the famous quote “That’s one small step for man, one giant leap for mankind,” or do not know where it came from. The story leading up to the moment a man walked on the moon, as well as everything that came after, is just as interesting and important as the moment itself. The significance of the history of America’s aeronautics programs cannot possibly be overestimated, and their story is one that is incredibly important to the modern world of today. It would not be the nation that it is, with the technology it possesses, without its crucial involvement in the “space race”. If the technology that sent a man to the moon did not exist, our daily lives would be impacted and basic tools would be missing. Beginning with America’s first official aeronautics organization, the National Advisory Committee for Aeronautics (or NACA) and continuing through to the present day and the National Aeronautics and Space Administration (or NASA), the story of America’s aerospace programs is interesting and extremely important. It is a story that spans many years and giant leaps in technology, and involves important locations like Wallops Flight Facility and Kennedy Space Center. From the early beginnings of NACA and Wallops, and continuing on to the rise and success of NASA and Kennedy Space Center, aeronautics

The space industry has produced many amazing technologies in the past from the development of fireproof material that makes up the modern firefighter suit to new forms of power generation. This is based on the fact that the National Aeronautics Space Agency (NASA)

During the year of 1986, on January the twenty sixth, a horrific shock was felt around the country. After Neil Armstrong’s landing on the moon, Americans felt a great sense of national pride and invincibility but many Americans learned on that fateful day that nobody is invincible; one of the worst catastrophes of the United States space program occurred on that day. About forty five seconds after liftoff, Americans witnessed the destruction of the breathtaking challenger space shuttle. Even though the disaster caused nationwide sadness, the reasons for its failure are clear. Named after the British ship that sailed across the Atlantic hundreds of years, could carry more than two thousand pounds the challenger was truly a glorious achievement.

With seven ‒ novice as well as seasoned ‒ astronauts on board, they were going to space to deploy a satellite “into orbit to observe Halley’s comet”(“The Space Shuttle Challenger Accident” 256). The first affirmation of a problem was gray smoke, this was detected 678 seconds into flight. Shortly after the smoke there was a small flame and “at 73 seconds, the Challenger reached an altitude of 46,000 feet and exploded”(“The Space Shuttle Challenger Accident” 256). That evening, President Ronald Reagan said: “We will never forget them, nor the last time we saw them this morning as they prepared for their journey and waved goodbye”(“The Space Shuttle Challenger Accident” 256). Five months later, in June 1986, it was conjectured “that a fuel leak through faulty rubber O-rings that sealed joint sections of the rocket booster caused the accident”(“The Space Shuttle Challenger Accident”

In 1972, Nixon completed one of his most impacted successes of his life and the life of America. What Nixon did was sign a bill giving the “ok” to build the U.S space shuttle (Accomplishments). The space shuttle represented a giant leap forward in the technology of space travel. Designed to function more like a cost-efficient “reusable” airplane than a one-use-only rocket-launched capsules, the shuttle afforded NASA pilots and scientists more time in space with which to conduct space-related research. Due to Nixon’s hard work and research NASA launched Columbia, the first space shuttle, in 1981 (Accomplishments).

The Challenger Disaster was one of the biggest events of the 1980’s. It symbolized that space travel is a challenging endeavor which bears it’s own set of risks, especially when the entirety of the shuttle program was plagued with issues up until the Challenger incident. Initially, America put a ton of resources into the space program in order to achieve the goal of winning the Space Race. Once that goal was achieved, America’s space program was scaled down to a fraction of the previous budget (space.com article). Out of the small budget, the shuttle program came into existence. During it’s conception, various bedget cuts and

The invention of new technology carried over throughout the years. After World War II, technology has progressed so much, that the first space shuttle had been made in 1957. Technology only progressed further to put rovers on other planets by 2004. By 1971, there was enough equipment to make computers.

The Cold War was a turning point in both technological advancements and education in the hard sciences. Because of the Cold War, it formed several competitions, including the Nuclear Arms race and the Space Race. The United States continued their space passion by opening the space shuttle program in January of 1972, twenty-five years after the Cold War began. During the space shuttle programs, NASA sent over 600 astronauts to space, along with numerous other satellites. NASA’s space shuttles consisted of mainly three components which included the two 185,000 pound rocket boosters, orbiter, and the 78,100 pound external tank. Within the external tank were the shuttle’s propellants, which was mainly consisted of liquid hydrogen fuel and oxygen

On 1st of February, 2003, the space shuttle Columbia exploded when it re-entered the Earth’s atmosphere after finished a 16 days mission in space. All seven astronauts were dead because of this incident. The National Aeronautics and Space Administration (NASA) had stopped the space shuttle program for more than two years to investigate this tragedy. In the 16 days period, the astronauts did approximately 80 experiments on different categories, for example, life science and material science [1]. An investigation later has found out that the disaster was caused by a problem on the day that took off on 16th of January.

Unfortunately, there is always risk when it comes to space flight. This makes it difficult to determine what constitutes an “Acceptable” risk. A space agency has many worries such as their reputation with the public and the world, the success of their missions, and most importantly the lives of their staff and astronauts. Engineers are usually technically gifted but lacking in organization. This spawns a need for non-technical managers to oversee the day to day operations of projects and companies. While the engineers worry about the functionality of the project (in this case, a space shuttle), the managers worry about the cost to the company and the infamous pick 2 triangle of good, cheap, fast. This causes a disconnect between the engineers and the management where pressure from anything whether it be the public or CEO, can cause concerns to be overlooked.

to the side of it that disconnect when the shuttle gets into orbit. The rockets

Although the Space Elevator will not make trips to space faster, it will make trips to space more frequent and it will open up space to a new era of development. Perhaps the biggest factor propelling the idea of a space elevator is that it would significantly lower the cost of putting cargo into space. Although slower than the chemically propelled space shuttle, the lifters reduce launch costs from $10,000 to $20,000 per pound, to approximately $400 per pound. This dramatic drop of expense required to traverse space would finally allow private investors to invest in a new area, known as “space production”. For example, titanium produced in earth’s environment has a maximum tensile strength of 200,000 psi but in the zero gravity of space “in theory” the tensile strength of titanium can be increased to over 500,000 psi. In addition, titanium will be much easier to manipulate in space thereby giving rise to new applications—with double strength.
