Book Description
No convincing explanation for the anomalous behavior of the Atmospheric Structure Experiment temperature sensors at approximately 13 km altitude has been found. It occurred on all of the widely-spaced probes, in a similar fashion. A preliminary effort has been made to determine atmospheric chemical species which might be present at 13 km. The purpose of this effort is to initiate suggestions of possible chemical interactions and to explore the effects of the presence of possible metal reactants including condensation. Equilibrium fractions of chemical species were calculated at a variety of conditions. Baseline calculations were made for the altitudes near 13 km. For comparison calculations were also made at 13 km but with the introduction of plausible metal atoms. Craig, Roger A. NCC2-653...

Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 176. With the search for extra-solar planets in full gear, it has become essential to gain a more detailed understanding of the evolution of the other earth-like planets in our own solar system. Space missions to Venus, including the Soviet Veneras, Pioneer Venus, and Magellan, provided a wealth of information about this planet' enigmatic surface and atmosphere, but left many fundamental questions about its origin and evolution unanswered. This book discusses how the study of Venus will aid our understanding of terrestrial and extra-solar planet evolution, with particular reference to surface and interior processes, atmospheric circulation, chemistry, and aeronomy. Incorporating results from the recent European Venus Express mission, Exploring Venus as a Terrestrial Planet examines the open questions and relates them to Earth and other terrestrial planets. The goal is to stimulate thinking about those broader issues as the new Venus data arrive.

Book Description
The final orbit of Venus by the Magellan spacecraft in October 1994 brought to a close an exciting period of Venus reconnaissance and exploration. The scientific studies resulting from data collected by the Magellan, Galileo, and Pioneer missions are unprecedented in their detail for any planet except Earth. Venus II re-evaluates initial assessments of Venus in light of these and other spacecraft missions and ground-based observations conducted over the past 30 years. More than a hundred contributors summarize our current knowledge of the planet, consider points of disagreement in interpretation, and identify priorities for future research. Topics addressed include geology, surface processes, volcanism, tectonism, impact cratering, geodynamics, upper and lower atmospheres, and solar wind environment. The diversity of the coverage reflects the interdisciplinary nature of Venus science and the breadth of knowledge that has contributed to it. A CD-ROM developed by the Jet Propulsion Laboratory accompanies the book and incorporates text, graphics, video, software, and various digital products from selected contributors to the text. A multimedia interface allows users to navigate the text and the extensive databases included on the disk. Venus II is the most authoritative single volume available on the second planet. Its contents will not only help shape the goals of future Venus missions but will also enhance our understanding of current Mars explorations.

Book Description
Humanity has long been fascinated by the planet Mars. Was its climate ever conducive to life? What is the atmosphere like today and why did it change so dramatically over time? Eleven spacecraft have successfully flown to Mars since the Viking mission of the 1970s and early 1980s. These orbiters, landers and rovers have generated vast amounts of data that now span a Martian decade (roughly eighteen years). This new volume brings together the many new ideas about the atmosphere and climate system that have emerged, including the complex interplay of the volatile and dust cycles, the atmosphere-surface interactions that connect them over time, and the diversity of the planet's environment and its complex history. Including tutorials and explanations of complicated ideas, students, researchers and non-specialists alike are able to use this resource to gain a thorough and up-to-date understanding of this most Earth-like of planetary neighbours.
