This book was released on 2018-11-07 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current Lower Earth Orbit (LEO) environment has become overly crowded with space debris. An evaluation of types of debris is presented in order to determine which debris poses the greatest threat to operation in space, and would therefore provide a feasible target for removal. A target meeting these functional requirements was found in the Cosmos C-1B Rocket Body. These launchers are spent space transporters which constitute a very grave risk of collision and fragmentation in LEO. The motion and physical characteristics of these rocket bodies have determined the most feasible method of removal. The proposed Orbital Debris Collector (ODC) device is designed to attach to the Orbital Maneuvering Vehicle (OMV), which provides all propulsion, tracking, and power systems. The OMV/ODC combination, the Rocket Body Retrieval Vehicle (RBRV), will match orbits with the rocket body, use a spin table to match the rotational motion of the debris, capture it, despin it, and remove it from orbit by allowing it to fall into the Earth's atmosphere. A disposal analysis is presented to show how the debris will be deorbited into the Earth's atmosphere. The conceptual means of operation of a sample mission is described.

Download or read book Conceptual Design of a Space Vehicle for Orbital Debris Protection written by Daniel Thomson and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As the orbital debris environment deteriorates, the threat to spacecraft is becoming increasingly significant. Additionally, current protection techniques leave them vulnerable to objects between 1 and 10 cm. The objective for this project was to design a "defender" space vehicle capable of shielding spacecraft from objects in this range of sizes. The design was divided into three stages: first, using SPH simulations, a shield capable of defeating large projectiles was designed based on existing shield types; next, a deployment mechanism that allowed the shield to be stored compactly for launch was designed and analyzed using a vector-based kinematics and dynamics method; finally, a general design of the service module was made. The final design consisted of an eight-layer shield with an umbrella-inspired deployment mechanism. It was 3 m in diameter by 7 m long with the shield folded and had a mass of 5100 kg; proving the feasibility of this measure.

Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of space flight, the collision hazard in Earth orbit has increased as the number of artificial objects orbiting the Earth has grown. Spacecraft performing communications, navigation, scientific, and other missions now share Earth orbit with spent rocket bodies, nonfunctional spacecraft, fragments from spacecraft breakups, and other debris created as a byproduct of space operations. Orbital Debris examines the methods we can use to characterize orbital debris, estimates the magnitude of the debris population, and assesses the hazard that this population poses to spacecraft. Potential methods to protect spacecraft are explored. The report also takes a close look at the projected future growth in the debris population and evaluates approaches to reducing that growth. Orbital Debris offers clear recommendations for targeted research on the debris population, for methods to improve the protection of spacecraft, on methods to reduce the creation of debris in the future, and much more.

Book excerpt: When the first sputnik was launched and the space era began, few gave thought to the possible negative impact of putting satellites into orbit. In fact, man's space activity has led to the formation of a new media named "space debris," i.e. man-made objects and their fragments launched into space, currently inactive and no longer serving any useful purpose. Space Debris: Hazard Evaluation and Mitigation will appeal to readers unfamiliar with the issues, as well as experts and designers. It introduces concepts behind the problems of space ecology. The volume features actual data on the space debris environment; new mathematical models for space debris evolution, production and self-production; description of the existing software and concepts for shield design. The author also reviews methods of collision risk assessment, including the attitudes and inclinations of orbits, collision hazard evaluation and suggestions for preventative measures.

This book was released on 1989 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The orbital debris environment model contained in this report is intended to be used by the spacecraft community for the design and operation of spacecraft in low Earth orbit. This environment, when combined with material dependent impact tests and spacecraft failure analysis, is intended to be used to evaluate spacecraft vulnerability, reliability, and shielding requirements. The environment represents a compromise between existing data to measure the environment, modeling of these data to predict the future environment, the uncertainty in both measurements and modeling, and the need to describe the environment so that various options concerning spacecraft design and operations can be easily evaluated.
