Book excerpt: With the launch of the Constellation program, NASA finds itself with the opportunity to design the next generation of manned vehicles that will take man to the Moon and beyond in the next two decades. While there are precedents for many aspects of the design, development, test, and evaluation (DDT&E) task at hand - the Apollo program, Space Transportation System, International Space Station (ISS) and others - the Johnson Space Center (JSC) Astronaut Office asked for a fresh look at first principles during the formative times of this new program. As a result, a team directed by the NASA Engineering and Safety Center (NESC) collected methodologies for how best to develop safe and reliable human rated systems and how to identify the drivers that provide the basis for assessing safety and reliability. The team also identified techniques, methodologies, and best practices to assure that NASA can develop safe and reliable human rated systems. The results are drawn from a wide variety of resources, from experts involved with the space program since its inception to the best-practices espoused in contemporary engineering doctrine. This report focuses on safety and reliability considerations and does not duplicate or update any existing references. Neither does it intend to replace existing standards and policy.

Book excerpt: NASA is currently in the process of developing the next generation crewed and cargo launch vehicles and spacecraft to return to the Moon and beyond. With the experience and knowledge base available to NASA from past similar programs, it is important to develop a document that captures the salient aspects of successful programs and serve as an important guide in evaluating next generation and future spacecraft concepts and proposals. This section outlines design, development, testing, and evaluation best practices for robust, reliable space systems. The scope of the section is limited to the space structural and pressurized systems (pressure vessels and pressurized structure). These components are critical to mission success and must operate safely and reliably. As an integrated structural system, the reliability at system level must be shown as well, through analysis and testing, to exceed the stipulated performance metrics of the program. Previous history and experience with similar structural designs provides background and guidance for future designs. Although this section is intended to address the reliability of the space structural systems, the methods and practices specified herein should be applicable to structural components (adaptive structures, engines, rocket nozzles, and thermal protection systems) in other disciplines (propulsion, mechanisms, etc.). To this end, the practices that were followed in similar heritage programs such as the Apollo, Space Shuttle, etc., were first examined. Of special interest are various lessons learned, documented failures, as well as successful designs. In addition, various tools and techniques used in preliminary design, detailed analysis, and verification/validation are documented. Acceptance tests and testing procedures with emphasis on how these tests uncovered errors and defects unforeseen in design and analysis are also described.

Download or read book Software and System Safety written by Terry L. Hardy and published by AuthorHouse. This book was released on 2012 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: System safety is a widely accepted management and engineering approach to analyze and address risks in complex systems in order to prevent accidents. Because software and computing systems are integral to most systems, software safety has become a critical component of an overall system safety effort. Software and System Safety discusses critical elements of the discipline of system safety and shows how software and computing systems fit in the system safety process. Software-specific aspects of the system safety process are addressed to show concerns common to complex systems. The many accidents and incidents presented in this book illustrate important lessons learned and show how software-related hazards can be misidentified, software risks can be improperly assessed, hazard controls may be misapplied, and software and system testing may not effectively verify that the risk had been reduced. The lessons learned come from a variety of industries and organizations, and include the author’s personal experience. The real-world lessons provided in this book can be used to improve existing software safety and system safety efforts, and can help when planning new system safety programs.
Download or read book The System Safety Skeptic written by Terry L. Hardy and published by AuthorHouse. This book was released on 2010 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced technologies and increasing automation have forever changed how systems work and how people interact with them. Transportation systems, energy extraction and production systems, medical devices, and manufacturing processes are increasingly complex. With the use of these complex systems comes increased potential for harm to humans, property, and the environment. System safety is a widely accepted management and engineering approach to analyze and address risks in these complex systems. When used correctly, system safety methods can provide tremendous benefits, focusing resources to reduce risk and improve safety. But poor system safety analyses can lead to overconfidence, and can result in a misunderstanding of the potential for harm. The System Safety Skeptic describes critical aspects of the discipline of system safety, including: Safety planning Hazard identification Hazard risk assessment and associated risk decision making Risk reduction and hazard controls Risk reduction verification Hazard tracking and anomaly reporting Safety management and culture Accidents in multiple industries and organizations are used to illustrate potential missteps in the system safety process, including: Failure to plan and implement systematic safety efforts, and failure to plan for emergencies Failure to accurately identify the hazards and what can go wrong Underestimating the chances that an accident could happen Underestimating the worst possible outcomes Overestimating the effectiveness of safeguards Failure to properly verify that safeguards actually work Failure to learn from the past Failure of the organization to adequately manage system safety efforts This book provides hundreds of lessons learned in safety management and engineering, drawing from examples from many industries as well as the author's years of experience in the field. These real-world lessons help foster a healthy skepticism toward safety analysis and management in order to prevent future accidents.

This book was released on 2018-05-29 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: While human-system interaction occurs in all phases of system development and operation, this chapter on Human Factors in the DDT&E for Reliable Spacecraft Systems is restricted to the elements that involve "direct contact" with spacecraft systems. Such interactions will encompass all phases of human activity during the design, fabrication, testing, operation, and maintenance phases of the spacecraft lifespan. This section will therefore consider practices that would accommodate and promote effective, safe, reliable, and robust human interaction with spacecraft systems. By restricting this chapter to what the team terms "direct contact" with the spacecraft, "remote" factors not directly involved in the development and operation of the vehicle, such as management and organizational issues, have been purposely excluded. However, the design of vehicle elements that enable and promote ground control activities such as monitoring, feedback, correction and reversal (override) of on-board human and automation process are considered as per NPR8705.2A, Section 3.3.Adelstein, Bernard and Hobbs, Alan and OHara, John and Null, CynthiaLangley Research CenterHUMAN FACTORS ENGINEERING; SYSTEMS ENGINEERING; ACTIVITY (BIOLOGY); GROUND BASED CONTROL; HUMAN REACTIONS; PROCEDURES; FABRICATION; FEEDBACK; MAINTENANCE
Download or read book Safety Design for Space Systems written by Tommaso Sgobba and published by Elsevier. This book was released on 2023-07-25 with total page 1190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lack of widespread education in space safety engineering and management has profound effects on project team effectiveness in integrating safety during design. On one side, it slows down the professional development of junior safety engineers, while on the other side it creates a sectarian attitude that isolates safety engineers from the rest of the project team. To speed up professional development, bridge the gap within the team, and prevent hampered communication and missed feedback, the entire project team needs to acquire and develop a shared culture of space safety principles and techniques.The second edition of Safety Design for Space Systems continues to address these issues with substantial updates to chapters such as battery safety, life support systems, robotic systems safety, and fire safety. This book also features new chapters on crew survivability design and nuclear space systems safety.

This book was released on 2019-01-16 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document establishes the structural requirements for human-rated spaceflight hardware including launch vehicles, spacecraft and payloads. These requirements are applicable to Government Furnished Equipment activities as well as all related contractor, subcontractor and commercial efforts. These requirements are not imposed on systems other than human-rated spacecraft, such as ground test articles, but may be tailored for use in specific cases where it is prudent to do so such as for personnel safety or when assets are at risk. The requirements in this document are focused on design rather than verification. Implementation of the requirements is expected to be described in a Structural Verification Plan (SVP), which should describe the verification of each structural item for the applicable requirements. The SVP may also document unique verifications that meet or exceed these requirements with NASA Technical Authority approval.

Download or read book Refinements to the Methods for Developing Spacecraft Exposure Guidelines written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-04-07 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human spaceflight is inherently risky, with numerous potential hazards posed at each phase of a mission. Potential health risks during spaceflights include short-term health consequences from being in microgravity, as well as long-term health consequences that arise, or continue, months or years after a flight. Additional health considerations are risks posed by exposure to environmental contaminants onboard spacecraft. Because the International Space Station and spacecraft are closed environments that require recirculation of air and water supplies, some contamination of the air and water will occur. Even with onboard air and water purification systems, chemicals will accumulate in the air and water as they recirculate or are recycled onboard. Therefore, it is necessary for the National Aeronautics and Space Administration (NASA) to identify hazardous contaminants and determine exposure levels that are not expected to pose a health risk to astronauts. NASA uses spacecraft maximum allowance concentrations (SMACs) and spacecraft water exposure guidelines (SWEGs) to provide guidance on acceptable exposures to air and water contaminants during normal operations and emergency situations. Refinements to the Methods for Developing Spacecraft Exposure Guidelines updates the methods for establishing SMACs and SWEGs and assists NASA with identifying chemicals that need updated SMACs or SWEGs and new chemicals for which these guidelines should be developed.
