Space Shuttle Case Study

Superior Essays
The fifth system engineering process is identification and prioritization of technical performance measures (TPMs). This part of the process will ensure the designer what is more important (Blanchard). An “objective tree,” like in figure 2 below, may help in facilitating the prioritization task of this process. For instance, is it more important to maximize cost effectiveness or to maximize system effectiveness? In the case of the space shuttle for NASA, they prioritized on maximizing cost effectiveness due to the budget cuts they received during the 1970s (“Challenger…”). They figured it will be more cost effective to have a reusable space shuttle instead of a disposable one. Therefore, they prioritized in designing a reusable space shuttle. …show more content…
Therefore, it’ll require a component to hold the satellite along with the crew. Also, the orbiter will need to handle additional payloads. If this function fails, the space shuttle would not be able to take flight or safely fly up to space with the satellite. Furthermore, there should be an additional thrust to help the orbiter to escape the gravitational pull. Therefore, it will need a component to do this task. This component ended up being the solid rocket boosters. Also, the solid rocket boosters were required to provide 80% of thrust and operate in parallel with the main engines of the orbiter for two minutes (Dunbar). Another primary function of the space shuttle is to be reusable. Majority of components needed to be reusable for future launches to cut down cost. For instance, the orbiter needs to be reusable after each launch. Also, the solid rocket boosters will be recovered and refurbished after each launch. If this reusability function fails, then the cost of each launch will still be high. This function is important, since one of NASA’s requirements is to cut down cost due to the budget cuts in the 1970s …show more content…
The critical part of the construction process is to make sure the design that was tested, evaluated, and optimized matches the system being constructed (Blanchard). The Challenger space shuttle was constructed by its design fully. Due to its faulty design, the challenger was doomed to fail. The operational use and life cycle support process indicate how long this system, the space shuttle, will last since it will degrade through time, use, and exposure. Lastly, the system retirement and material disposal process indicate how the system will be disposed once it

    Bottled oxygen will be required to sustain the astronauts and as a result will be used up very quickly. Water on Mars can be electrolysed to make oxygen using several redundant systems like on the international space station, but a backup for these systems in the event of failure or malfunction will be required. In the long term, terraforming is a solution. Changing the atmospheric composition on Mars will make it more habitable and eventually eliminate the need for bottled oxygen but this extremely research intensive activity could take thousands of years to achieve its desired end…

    If the SLS gets more funding, perhaps NASA would actually start developing some parts for rocket, and more importantly: payloads for the rocket to launch. This would eventually lead to the future goal of humans on mars, but that would still not happen for a long time. The other option scraps SLS entirely and puts the responsibility in the hands of private space companies. These companies have already proved to be more efficient in terms of development time and cost. Private companies can raise funds from investors, source supplies from anywhere, and avoid government inefficiencies.…

    NASA Space Regulation

    Since the glory days of the American space program are long past, the role of the National Aeronautic and Space Administration should pivot — from space exploration to space regulation. In particular, private companies — not NASA — should undertake the exploration of space and NASA should oversee these ventures, much as another federal agency, the FAA, oversees private aviation. Private space companies would go through rigorous tests and monitoring period and at a certain point be 'cleared ' for space travel with humans. This would be very successful because competition drives down prices, and the more companies there are, the cheaper it would be to go to space. Also, this oversight would allow NASA to discover more and do more, due to the…

    These past few years the US government has drastically lowered the amount of funding NASA receives, hindering what they are able to do. However, recently privately owned companies such as SpaceX and Boeing have begun to design commercial space ships, and have even had major success and break through with those ships. Space is one of the last places, that we’re able to truly explore and find new things that could possibly help us back here on earth. Given this, NASA should receive a higher amount of funding so that it may keep up with the privately owned companies, explore new planets that could be used for colonization, and explore and discover of new and exotic places that we would never think were possible. Many people oppose the position…

    Space can push humanity towards better education. Using the STEM education system, (Science, Technology, Engineering, and Math) we can create a better field of workers capable for a space career. Even if we increase the education for a small part of the population, many will still not even have any type of education. We should worry about our world and not how to further our lives on a different one if we haven’t made the best of the world we occupy. Furthermore, the rocketry type, (thermal rocketry) is the same from what we used over 50 years ago.…

    One of the International Space Nation Missions is the ISS-RapidScat, which is a cost effective replacement for the QuikScat. It monitors ocean winds used to measure weather predictions. For example, it monitors for hurricanes. The QuikScat stopped working in 2009, so NASA was left with a problem. They had to come up with an instrument to replace it, but yet was cost effective.…

    But NASA is funded by the government, so the money is wasted for the United States economy. Upgrading and testing space shuttles and suits go towards to United States economy as stated before and that affects the world economy for the good to make more space shuttles and better suits. There are many more pros to expanding space exploration then there are cons to it. Many people believe expanding space exploration can increase our knowledge and help the the world as one in the long run. For example, according to Issit and Moreno-Riano, authors of We all…

    They do not know that space exploration is vital to their survival, or that they need space exploration to keep living the same lives they do today. They also take for granted the items that are now available to use thanks to NASA, which was created for space exploration. In a chart from Gallup, they show 68% of Americans think space exploration costs are justified (Majority of Americans Say Space Program Costs Justified). Space exploration is important for the human race to evolve, and to avoid extinction. People need to consider space exploration important and continue funding the program.…
