In lieu of using probability numbers, the NSTS [National Space Transportation System] relies on engineering judgment using rigid and well-documented design, configuration, safety, reliability, and quality assurance controls,” the Johnson authors continued. This outlook determined the data NASA managers required engineers to collect. For example, no “lapsed-time indicators” were kept on shuttle components, subsystems, and systems, although “a fairly accurate estimate of time and/or cycles could be derived,” the Johnson authors added.

A Space Shuttle : 12 Steps - Instructables A Space Shuttle : 12 Steps - Instructables

Hey man, Im going to use this for my school project, it looks awesome. When i'm finished do you want me to post a pic?Being a busy student, I made this at home at night times and weekends after completing homework. This project taught me many skills that I was able to incorporate into my other activities from school such as Science Olympiad and Robotics. In addition, I was able to demo the model at an exhibit to generate publicity about the importance of recycling. Lessons learned: in design, to use probabilistic risk assessment more in evaluating and assigning priorities to risks; in operation, to establish certain launch commit criteria that cannot be waived by anyone. Causes: inadequate original design (booster joint rotated farther open than intended); faulty judgment (managers decided to launch despite record low temperatures and ice on launch pad); possible unanticipated external events (severe wind shear may have been a contributing factor). My 1:78 scale model of the NASA Space Shuttle made completely out of recycled materials that can be found in a typical household (although my family is far from that...). As for painting, I chose not to paint it since I knew that it would look worse if I did the paint job. If you chose to paint it, I would recommend finding a non-water based spray paint since soggy models don't look nice.

The NRC committee had several criticisms. In practice, the FMEA was the sole basis for some engineering change decisions and all engineering waivers and rationales for re taining certain high-risk design features. However, the NRC report noted, hazard analyses for some important, high-risk subsystems “were not updated for years at a time even though design changes had occurred or dangerous failures were experienced.” On one procedural flow chart, the report noted, “the ‘Hazard Analysis As Required ’ is a dead-end box with inputs but no output with respect to waiver approval decisions.” Editor’s Note: Today is the 30 th anniversary of the loss of the space shuttle Challenger, which was destroyed 73 seconds in its flight, killing all onboard. To mark the anniversary, IEEE Spectrum is republishing this seminal article which first appeared in June 1989 as part of a special report on risk. The article has been widely cited in both histories of the space program and in analyses of engineering risk management. Despite the potential benefits for the Air Force, the military was satisfied with its expendable boosters and did not need or want the shuttle as much as NASA did. Because the space agency needed outside support, the Defense Department (DoD) and the National Reconnaissance Office (NRO) gained primary control over the design process. For example, NASA planned a 40-by-12-foot (12.2 by 3.7m) cargo bay, but NRO specified a 60-by-15-foot (18.3 by 4.6m) bay because it expected future intelligence satellites to become larger. When Faget again proposed a 12ft (3.7m) wide payload bay, the military almost immediately insisted on retaining the 15ft (4.6m) width. The Air Force also gained the equivalent of the use of one of the shuttles for free despite not paying for the shuttle's development or construction. In exchange for the NASA concessions, the Air Force testified to the Senate Space Committee on the shuttle's behalf in March 1971. [4] :216,232–234 [5] Statistics don’t count for anything,” declared Will Willoughby, the National Aeronautics and Space Administration’s former head of reliability and safety during the Apollo moon landing program. “They have no place in engineering anywhere.” Now director of reliability management and quality assurance for the U.S. Navy, Washington, D.C., he still holds that risk is minimized not by statistical test programs, but by “attention taken in design, where it belongs.” His design-­oriented view prevailed in NASA in the 1970s, when the space shuttle was designed and built by many of the engineers who had worked on the Apollo program.

I am currently an engineering student at UCLA and look forward to sharing more projects with the Instructables community… I made a 1:78 scale model of the NASA Space Shuttle completely out of recycled materials using tools that are common and can be found in an average house. I mainly used cardboard and Elmer's glue. The Space Shuttle program used the HAL/S programming language. [10] The first microprocessor used was the 8088 and later the 80386. The Space Shuttle orbiter avionics computer was the IBM AP-101.
