This book was released on 1973 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: A potential interference problem for the Viking '75 scientific investigation of the Martian surface resulting from retrorocket exhaust plume impingement of the surface was investigated experimentally and analytically. It was discovered that the conventional bell nozzle originally planned for the Viking Lander retrorockets would produce an unacceptably large amount of physical disturbance to the landing site. An experimental program was subsequently undertaken to find and/or develop a nozzle configuration which would significantly reduce the site alteration. A multiple nozzle configuration, consisting of 18 small bell nozzles, was shown to produce a level of disturbance that was considered by the Viking Lander Science Teams to be acceptable on the basis of results from full-scale tests on simulated Martian soils.

Download or read book Preventing the Forward Contamination of Mars written by National Research Council and published by National Academies Press. This book was released on 2006-04-22 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent spacecraft and robotic probes to Mars have yielded data that are changing our understanding significantly about the possibility of existing or past life on that planet. Coupled with advances in biology and life-detection techniques, these developments place increasing importance on the need to protect Mars from contamination by Earth-borne organisms. To help with this effort, NASA requested that the NRC examine existing planetary protection measures for Mars and recommend changes and further research to improve such measures. This report discusses policies, requirements, and techniques to protect Mars from organisms originating on Earth that could interfere with scientific investigations. It provides recommendations on cleanliness and biological burden levels of Mars-bound spacecraft, methods to reach those levels, and research to reduce uncertainties in preventing forward contamination of Mars.

Download or read book Hydrazine and Its Derivatives written by Eckart Walter Schmidt and published by John Wiley & Sons. This book was released on 2001-08-24 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new edition of the authoritative source on hydrazine chemistry In the past century, hydrazine, an important intermediate in the synthesis of countless chemicals with N-N bonds, has grown into a major industrial commodity with a wide range of uses. It is used as a fuel in rocket propulsion, as a boiler feedwater deoxygenating agent, and in the manufacture of foamed plastics, pharmaceuticals, and biodegradable pesticides and herbicides, to name just a few uses. Since the first edition of Hydrazine and Its Derivatives: Preparation, Properties, Applications was published in 1984, there has been considerable development in this field and many new aspects of hydrazine chemistry and applications have evolved. Offering an overview of hydrazines and their industrial applications, this book also provides a compilation of numerous references to the scientific and technical literature arranged in a systematic manner, allowing the reader to find the necessary information by accessing the pages either from the table of contents or the alphabetical subject index. Some other features of the significantly enlarged Second Edition include: Frequent "see also" cross-references/links to other relevant sections of the bookOver 8,400 references, most of which cover the period from 1980 to 1998 Extremely thorough, encyclopedia-style coverage of topics Information to aid in the design of environmentally benign, biodegradable pesticides and more energetic rocket propellants Background information on the adverse effects of pesticide residue in food Hydrazine and Its Derivatives: Preparation, Properties, Applications, Second Edition is the most comprehensive book ever published on hydrazines, and this new edition is indispensable reading material for chemists, toxicologists, environmentalists, propulsion engineers, materials engineers, and satellite builders.
