Book excerpt: The Eglin FPS-85 space surveillance radar is a bi-static phased array radar system located in Northern Florida. In 1994, when a new radar control computer was installed at Eglin, the software for the debris fence was not budgeted. The radar only maintained the capability to erect low elevation angle surveillance fences. The software was upgraded in 1999 to create the debris fence, which extends from 155 to 205 degrees in azimuth and is scanned at 35-degrees elevation. This higher elevation angle enables the detection of smaller-sized debris objects at manned space flight orbits. In this configuration, the radar system has a 0.99 probability of detection for all objects that have a radar cross-section greater than -35 dBsm. The new debris fence is intended to enhance the AFSPC's and NASA's ability to detect small debris objects, which are not currently part of the SSN satellite catalog. This paper presents data collected during software version 99-1 development testing.

Book excerpt: In light of increasing and increasingly serious collisions of debris with the Space Shuttle, the 29 papers look at measuring and modelling space debris and meteoroids; risk analysis and protection; and mitigation measures, space debris handbooks, and standards. The topics include space-based observations of orbital debris, numerical and experimental studies of the shaped charge for assessing space debris, and self-induced collision hazard in high and moderate inclination satellite constellations.

Available in PDF, EPUB and Kindle. Book excerpt: The future evolution of the debris environment will be forecast on the basis of traffic models and possible hazard mitigation practices. The text shows how large trackable objects will have re-entry pinpointed and predictions made on related risk assessment for possible ground impact. Models will also be described for meteoroids which are also a prevailing risk.

Download or read book Space Dust and Debris written by COSPAR. Plenary Meeting and published by Elsevier Science & Technology. This book was released on 1991 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers presented in this publication can be divided into three sections. The section entitled Orbital Debris includes papers which develop techniques to define the environment through models which describe spacecraft traffic and fragment generation from explosions and random collisions; papers which test model predictions through measurements of the environment, the effect that the environment will have on spacecraft and scientific investigations; and techniques to either minimise the effect of the environment or minimise the environment. In Situ Measurement and Laboratory Analysis of Space Dust Particles presents data from NASA's Long Duration Exposure Facility (LDEF) following its recovery by the space shuttle in January 1990. The importance of the LDEF data for an understanding of the particulate space environment is apparent from the preliminary analysis. Ideas on the interrelations between asteroids, comets and dust are changing rapidly. Observations from the spacecraft IRAS, VEGA, GIOTTO and groundbased telescopes have defined more clearly the nature of comets and asteroids.

This book was released on 2003 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vols. 2-6 of the CAIB's Final Report contain appendices that provide the supporting documentation for the main text of the Final Report contained in Vol. 1, which was released on Aug. 26, 2003. These appendix materials were working documents. They contain a number of conclusions and proposed recommendations, several of which were adopted by the CAIB in Vol. 1. The other conclusions and proposed recommendations drawn in Vols. 2-6 do not necessarily reflect the views of the CAIB but are included for the record. When there is conflict, Vol. 1 takes precedence. It alone is the CAIB's official statement.
Download or read book Khobar Towers Tragedy and Response written by Perry D. Jamieson and published by Government Printing Office. This book was released on 2008 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This account of the Khobar Towers bombing tells the story of the horrific attack and the magnificent response of airmen doing their duty under nearly impossible circumstances. None of them view their actions as heroic, yet the reader will marvel at their calm professionalism. All of them say it was just their job, but the reader will wonder how they could be so well trained to act almost instinctively to do the right thing at the right time. None of them would see their actions as selfless, yet countless numbers refused medical attention until the more seriously injured got treatment. Throughout this book, the themes of duty, commitment, and devotion to comrades resoundingly underscore the notion that America's brightest, bravest, and best wear her uniforms in service to the nation. This book is more than heroic actions, though, for there is also controversy. Were commanders responsible for not adequately protecting their people? What should one make of the several conflicting investigations following the attack? Dr. Jamieson has not shied away from these difficult questions, and others, but has discussed them and other controversial judgments in a straightforward and dispassionate way that will bring them into focus for everyone. It is clear from this book that there is a larger issue than just the response to the bombing. It is the issue of the example set by America's airmen. Future airmen who read this book will be stronger and will stand on the shoulders of those who suffered and those who made the ultimate sacrifice.
Download or read book History of On Orbit Satellite Fragmentations 14th Edition written by Nicholas L. Johnson and published by www.Militarybookshop.CompanyUK. This book was released on 2008-06 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Includes full color illustrations. Since the first serious satellite fragmentation occurred in June 1961 (which instantaneously increased the total Earth satellite population by more than 400%) the issue of space operations within the finite region of space around the Earth has been the subject of increasing interest and concern. The prolific satellite fragmentations of the 1970s and the marked increase in the number of fragmentations in the 1980s served to widen international research into the characteristics and consequences of such events. Continued events in all orbits in later years make definition and historical accounting of those events crucial to future research. Large, manned space stations and the growing number of operational robotic satellites demand a better understanding of the hazards of the dynamic Earth satellite population.
