Revell 04736 Space Shuttle Discovery & Booster Rockets 1:144 Scale Unbuilt/Unpainted Plastic Model Kit, Multi-color, 59.5 x 36.4 x 6.5 centimetres

Product Information

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. NASA’s “management methodology” for collection of data and determination of risk was laid out in NASA’s 1985 safety analysis for Galileo. The Johnson space center authors explained: “Early in the program it was decided not to use reliability (or probability) numbers in the design of the Shuttle” because the magnitude of testing required to statistically verify the numerical predictions “is not considered practical.” Furthermore, they noted, “experience has shown that with the safety, reliability, and quality assurance requirements imposed on manned space­flight contractors, standard failure rate data are pessimistic.”

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.Another reason was NASA’s “normal program development: you don’t continue to take data; you certify the components and get on with it,” said Rodney’s deputy, James Ehl. “People think that since we’ve flown 28 times, then we have 28 times as much data, but we don ’t. We have maybe three or four tests from the first development flights.” 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. As another incentive for the military to use the shuttle, Congress reportedly told DoD that it would not pay for any satellites not designed to fit into the shuttle cargo bay. [6] Although NRO did not redesign existing satellites for the shuttle, the vehicle retained the ability to retrieve large cargos such as the KH-9 HEXAGON from orbit for refurbishment, and the agency studied resupplying the satellite in space.

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). 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. The probabilities originated in a series of quantitative risk assessments NASA was required to conduct by the Interagency Nuclear Safety Review Panel (INSRP), in anticipation of the launch of the Galileo spacecraft on its voyage to Jupiter, originally scheduled for the early 1980s. Galileo was powered by a plutonium-­fueled radioisotope thermoelectric generator, and Presidential Directive/NSC-25 ruled that either the U.S. President or the director of the office of science and technology policy must examine the safety of any launch of nuclear material before approving it. The INSRP (which consisted of representatives of NASA as the launching agency, the Department of Energy, which manages nuclear devices, and the Department of Defense, whose Air Force manages range safety at launch) was charged with ascertaining the quantitative risks of a catastrophic launch dispersing the radioactive poison into the atmosphere. There were a number of studies because the upper stage for boosting Galileo into interplanetary space was reconfigured several times.
