Available in PDF, EPUB and Kindle. Book excerpt: The report presents the results of Phase II of a research and development effort to provide quantitative information on the effects of earth contours and ground plane snow covers on the Null-Reference, Sideband-Reference, and Capture-Effect Glide Path Systems. The mathematical model developed in Phase I (see AD-618 085) was used to predict the amplitude and position of glide path roughness at Pittsburgh, Pennsylvania; Charleston, West Virginia; and Ohio University Airport, Athens, Ohio, due to reflection of signals from irregular terrain in the approach region. Pittsburgh and Charleston predictions were confirmed by comparing with FAA flight inspection data. Development of a second mathematical model begun in Phase I was completed in this phase to provide a clear indication of effects on the monitor produced by snow coverings on the earth between the transmitter and the monitor. Computer calculations demonstrated that the glide path angle may be expected to increase or decrease at the monitor depending on the value of the dielectric constant of the snow. Low values of dielectric constant which are associated with light, fluffy, dry snow produce a decrease in path angle at the monitor and a wet snow with a high dielectric constant produces a raising of this path angle. Evidence from field measurements corroborates the calculated results. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: NASA commissioned the Columbia Accident Investigation Board (CAIB) to conduct a thorough review of both the technical and the organizational causes of the loss of the Space Shuttle Columbia and her crew on February 1, 2003. The accident investigation that followed determined that a large piece of insulating foam from Columbia's external tank (ET) had come off during ascent and struck the leading edge of the left wing, causing critical damage. The damage was undetected during the mission. The Columbia accident was not survivable. After the Columbia Accident Investigation Board (CAIB) investigation regarding the cause of the accident was completed, further consideration produced the question of whether there were lessons to be learned about how to improve crew survival in the future. This investigation was performed with the belief that a comprehensive, respectful investigation could provide knowledge that can protect future crews in the worldwide community of human space flight. Additionally, in the course of the investigation, several areas of research were identified that could improve our understanding of both nominal space flight and future spacecraft accidents. This report is the first comprehensive, publicly available accident investigation report addressing crew survival for a human spacecraft mishap, and it provides key information for future crew survival investigations. The results of this investigation are intended to add meaning to the sacrifice of the crew's lives by making space flight safer for all future generations.
