This book was released on 2013-03-07 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft study of the Solar system is one of humanity's most outstanding achievements. Thanks to this study, our present knowledge of properties of and conditions on the planets exceeds many-fold that of 20 years ago: planets have been rediscovered. This is especially the case for planetary atmospheres, whose properties were for the most part either not at all or only erroneously known. Much research has been invested in the study of the atmospheres of Mars and Venus, and their chemical composition and photochemistry are basic problems in these studies. In the present publication I have tried to summarize all findings in this field. The English version of the book includes new data in the field from the last 3 years since the book was published in Russian.

Download or read book Muadee written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-18 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document is the final report of the MAUDEE (Mars Upper Atmosphere Dynamics, Energetics, and Evolution) consortium. It describes a low cost Discovery mission to investigate the upper atmosphere of Mars and to understand the manner in which Mars has evolved over geologic time. In keeping with the innovative philosophy permeating the Discovery Program and in order to minimize the burden of reading an extensive prose exposition, a new presentation format has been adopted. The format involves a series of view graphs with facing text. The view graphs form the basis of a complete oral presentation of the MAUDEE mission and the facing text provides more detailed, but still brief, explanatory descriptions. Readers can scan the view graphs and/or read the facing text at their discretion. The oral presentation of this study was given to code SL personnel at NASA Headquarters on February 23, 1994. MAUDEE is an essential component of the Mars Exploration Program. It provides the information required to understand the evolution of the planet via the escape of volatiles. It provides the key measurements needed to understand the upper atmosphere of the last of the three terrestrial planets to be so studied. It connects and supplements investigations based on other Mars missions: Mars Surveyor, Planet-B and Mars-96. The MAUDEE mission plan involves a combination of remote and in-situ sensors, housed in three instrument packages. The sensors make measurements of the atmospheric regions between 60-200 km. These instruments are based on extensive heritage from Earth explorers and Pioneer Venus. The mission scenario has several phases and employs aerobraking maneuvers to lower initial apoapsis, thereby reducing fuel requirements. The spacecraft has body-mounted solar cells, enabling deep diving into the Martian atmosphere. The orbital inclination allows for pole-to-pole latitudinal sweeps in an initial elliptical phase, followed by a circular phase affording detailed diurnal measur...

This book was released on 2019-02-14 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemical composition of any planetary atmosphere is of fundamental importance in determining its photochemistry and dynamics in addition to its thermal balance, climate, origin and evolution. Divided into two parts, this book begins with a set of introductory chapters, starting with a concise review of the Solar System and fundamental atmospheric physics. Chapters then describe the basic principles and methods of spectroscopy, the main tool for studying the chemical composition of planetary atmospheres, and of photochemical modeling and its use in the theoretical interpretation of observational data on chemical composition. The second part of the book provides a detailed review of the carbon dioxide atmospheres and ionospheres of Mars and Venus, and the nitrogen-methane atmospheres of Titan, Triton and Pluto. Written by an expert author, this comprehensive text will make a valuable reference for graduate students, researchers and professional scientists specializing in planetary atmospheres.

This book was released on 2013 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of this thesis is to contribute to a better understanding of the dynamics of the Venusian atmosphere, constraining its characterization at cloud top level, complementing the observations of the Venus Express spacecraft with ground-based observations. In order to achieve this objective of studying the atmospheric super-rotation, I measured the zonal wind velocity (crosswind the planet from East to West) and its spatial and temporal variability, by means of high precision spectroscopy and Doppler velocimetry. The observations were made with the high-resolution spectrograph UVES with ESO's Very Large Telescope (VLT) and with the high-resolution ESPaDOnS spectropolarimeter at the Canada-France-Hawaii telescope (CFHT) at Mauna Kea observatory. I use a method of direct measurement of the planetary winds based on high resolution spectroscopy in the visible range. The atmosphere of Venus contains highly scattering aerosols in suspension, mostly at cloud top layer. This cloud deck covers entirely the planet, imposing an unusually high albedo. These particles are carried by the wind, carrying with them the information on atmospheric dynamics. The upper cloud layer is located about 70 km altitude. This altitude corresponds to the maximum velocity of zonal superrotation. The method used, in the case of long-slit observations obtained with VLT/UVES, allowed to characterize the spatial variations of zonal wind as a function of latitude (since the slit is thin compared to the size of the disk image of Venus), and a comparison with VEx/VIRTIS cloud tracking was also performed using CFHT/ESPaDOnS.

This book was released on 2018-07-23 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upper Atmosphere Research Satellite flight data from the first 737 days after launch (September 1991) was used to investigate spacecraft disturbances and responses. The investigation included two in-flight dynamics experiments (approximately three orbits each). Orbital and configuration influences on spacecraft dynamic response were also examined. Orbital influences were due to temperature variation from crossing the Earth's terminator and variation of the solar incident energy as the orbit precessed. During the terminator crossing, the rapid ambient temperature change caused the spacecraft's two flexible appendages to experience thermal elastic bending (thermal snap). The resulting response was dependent upon the orientation of the solar array and the solar incident energy. Orbital influences were also caused by on-board and environmental disturbances and spacecraft configuration changes resulting in dynamic responses which were repeated each orbit. Configuration influences were due to solar array rotation changing spacecraft modal properties. The investigation quantified the spacecraft dynamic response produced by the solar array and high gain antenna harmonic drive disturbances. The solar array's harmonic drive output resonated two solar array modes. Friction in the solar array gear drive provided sufficient energy dissipation which prevented the solar panels from resonating catastrophically; however, the solar array vibration amplitude was excessively large. The resulting vibration had a latitude-specific pattern. Woodard, Stanley E.
