Book excerpt: This report analyzes the probability of a launch vehicle colliding with one of the nearly 10,000 tracked objects orbiting the Earth, given that an object on a near-collision course with the launch vehicle has been identified. Knowledge of the probability of collision throughout the launch window can be used to avoid launching at times when the probability of collision is unacceptably high. The analysis in this report assumes that the positions of the orbiting objects and the launch vehicle can be predicted as a function of time and therefore that any tracked object which comes close to the launch vehicle can be identified. The analysis further assumes that the position uncertainty of the launch vehicle and the approaching space object can be described with position covariance matrices. With these and some additional simplifying assumptions, a closed-form solution is developed using two approaches. The solution shows that the probability of collision is a function of position uncertainties, the size of the two potentially colliding objects, and the nominal separation distance at the point of closest approach. ne impact of the simplifying assumptions on the accuracy of the final result is assessed and the application of the results to the Cassini mission, launched in October 1997, is described. Other factors that affect the probability of collision are also discussed. Finally, the report offers alternative approaches that can be used to evaluate the probability of collision.Bollenbacher, Gary and Guptill, James D.Glenn Research CenterCASSINI MISSION; LAUNCH VEHICLES; SPACE EXPLORATION; LAUNCH WINDOWS; SPACECRAFT LAUNCHING; MISSION PLANNING; PROBABILITY THEORY; COLLISIONS; COLLISION AVOIDANCE; COVARIANCE; MATRICES (MATHEMATICS)

Download or read book Limiting Future Collision Risk to Spacecraft written by National Research Council and published by National Academies Press. This book was released on 2011-12-16 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Derelict satellites, equipment and other debris orbiting Earth (aka space junk) have been accumulating for many decades and could damage or even possibly destroy satellites and human spacecraft if they collide. During the past 50 years, various National Aeronautics and Space Administration (NASA) communities have contributed significantly to maturing meteoroid and orbital debris (MMOD) programs to their current state. Satellites have been redesigned to protect critical components from MMOD damage by moving critical components from exterior surfaces to deep inside a satellite's structure. Orbits are monitored and altered to minimize the risk of collision with tracked orbital debris. MMOD shielding added to the International Space Station (ISS) protects critical components and astronauts from potentially catastrophic damage that might result from smaller, untracked debris and meteoroid impacts. Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Program examines NASA's efforts to understand the meteoroid and orbital debris environment, identifies what NASA is and is not doing to mitigate the risks posed by this threat, and makes recommendations as to how they can improve their programs. While the report identified many positive aspects of NASA's MMOD programs and efforts including responsible use of resources, it recommends that the agency develop a formal strategic plan that provides the basis for prioritizing the allocation of funds and effort over various MMOD program needs. Other necessary steps include improvements in long-term modeling, better measurements, more regular updates of the debris environmental models, and other actions to better characterize the long-term evolution of the debris environment.

Book excerpt: The amount of space debris is growing at an alarming rate, raising concern about its collision with operational spacecraft. This book analyzes the probability of such a collision when the orbits of two approaching objects are based on measurements with inherent errors. Many recent papers have dealt with the methodology of computing the collision probability in the encounter region, but they have assumed that the encounter is a flyby and is short-term, with the trajectories of the objects represented by straight lines. By contrast, Spacecraft Collision Probability, the outgrowth of the authors research during the past two decades, deals not only with those cases but also with important long-term cases in which objects spend protracted periods in the vicinity of each other. An extensive chapter is included on the International Space Station (ISS), to demonstrate how one would accurately gauge its probability of collision. The ISS is modeled according to its actual complex shape, component by componentenabling the detailed computation of a more realistic collision probability than one would obtain by the routine practice of modeling it as a sphere. In addition, the author developed Excel macros to obtain the numerical tables and graphical plots appearing in the book. That software is available on the Supporting Materials page of the AIAA Web site.

Download or read book Space Insurance: International Legal Aspects written by Katarzyna Malinowska and published by Kluwer Law International B.V.. This book was released on 2017-03-15 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insurance related to outer space activities has been around since the 1960s, but has become vastly more significant with the increased commercial use of satellites. This book focuses on the legal aspects of space insurance in the contractual context, analysing space risk as well as the insurance terms used on the market. It offers the first in-depth coverage, both practical and theoretical, of space insurance from an international law perspective. Attending throughout to the important and problematic distinction between the space segment (upstream) and ground segment (downstream) in space law, this book deals comprehensively with such issues and topics as the following: - the main hazards relating to space activities; - the impact of new space technologies on the level of risk and insurance; - the differing types of risks attributable to various entities in the context of insurable interest; - aspects of the space risk allocation regimes and risk assessment; - the impact of the five ‘space treaties’ – the Outer Space Treaty, the Liability Convention, the Rescue Agreement, the Registration Convention and the Moon Agreement – on the subject and scope of insurance coverage; - the advent of suborbital flight, commercial human space flight and space tourism in the context of emerging insurance risks; - the problem of space debris; - contractual aspects of space activities affecting the space insurance risks; - basic notions such as ‘outer space’, ‘space object’ in the context of space activities and related insurance coverage; - basic insurance principles and their operation in the space insurance; and - the adjustment of losses and the settlement of disputes in space insurance. The author emphasises the need to understand the various insurance risks facing particular types of commercial space activities, including pre-launch, launch, transportation, spaceflight, satellite communications, satellite navigation, satellite remote sensing and space station operation. Satellites are increasingly a vital part of many daily activities of contemporary society and the Earth’s orbit is becoming ever more crowded, heightening the risks of collision, damage and claims. This thoroughly researched book will therefore be extremely useful to lawyers, policymakers and academics tasked with defining the scope of insurance coverage that accurately mirrors technological, contractual and legal reality. Its practical aspect will be of extraordinary value to insurance lawyers, underwriters and brokers.
