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.

Book Description
The twenty-two papers contained in this volume have been selected from the Proceedings of the 2nd COSPAR Colloquium. The exploration of planet Mars will be the focal point of the planetary missions in the coming years, so the investigation of the surface and the upper layers of the soil is of primary importance. The major space agencies are actively working to understand the environmental and technical requirements of the planned missions and experiments and it is predicted that the planet will be host to both ground based and atmospheric investigations in the near future.

Book Description
A major surprise of the Apollo Moon missions was the deleterious impact of lunar dust on the astronauts, their spacesuits and other equipment, and even inside the Command/Service Module during their return to Earth. Lunar dust permeated everything and impacted mechanical systems. The dust on the Moon’s surface was disturbed and became airborne by the routine actions of the astronauts as they walked and performed their exploration of the lunar surface. Over the last decade, as NASA’s plans for the human exploration of Mars have developed and matured, a major concern has been the possible negative impacts of Mars surface and atmospheric dust on human health and on the human surface systems and surface operations on the Red Planet. In this book, 41 Mars scientists, mission engineers and planners and medical researchers have reviewed our current understanding and identified the knowledge gaps in a wide range of areas, including the chemical, physical and electrical properties of Mars atmospheric dust; the evolution and occurrence of localized, regional and planetary-scale dust storms; the human health effects of Mars atmospheric dust, including inhalation of and potential toxicity of dust particles; and the impact of Mars atmospheric dust on surface systems and on surface operations, among others.

Book Description
In recent years, planetary science has seen a tremendous growth in new knowledge. Deposits of water ice exist at the Moon's poles. Discoveries on the surface of Mars point to an early warm wet climate, and perhaps conditions under which life could have emerged. Liquid methane rain falls on Saturn's moon Titan, creating rivers, lakes, and geologic landscapes with uncanny resemblances to Earth's. Vision and Voyages for Planetary Science in the Decade 2013-2022 surveys the current state of knowledge of the solar system and recommends a suite of planetary science flagship missions for the decade 2013-2022 that could provide a steady stream of important new discoveries about the solar system. Research priorities defined in the report were selected through a rigorous review that included input from five expert panels. NASA's highest priority large mission should be the Mars Astrobiology Explorer Cacher (MAX-C), a mission to Mars that could help determine whether the planet ever supported life and could also help answer questions about its geologic and climatic history. Other projects should include a mission to Jupiter's icy moon Europa and its subsurface ocean, and the Uranus Orbiter and Probe mission to investigate that planet's interior structure, atmosphere, and composition. For medium-size missions, Vision and Voyages for Planetary Science in the Decade 2013-2022 recommends that NASA select two new missions to be included in its New Frontiers program, which explores the solar system with frequent, mid-size spacecraft missions. If NASA cannot stay within budget for any of these proposed flagship projects, it should focus on smaller, less expensive missions first. Vision and Voyages for Planetary Science in the Decade 2013-2022 suggests that the National Science Foundation expand its funding for existing laboratories and establish new facilities as needed. It also recommends that the program enlist the participation of international partners. This report is a vital resource for government agencies supporting space science, the planetary science community, and the public.

Book Description
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. I wish to thank U. von Zahn, who initiated my talks with Springer-Verlag and acted as technical editor. December 2, 1985 V. A.

Book Description
Paperback. This publication contains 18 papers on the planetary atmospheres and ionospheres, and reference atmospheres. The papers survey the latest results, including experimental and numerical modelling and theoretical research of the atmospheres of planets. Presented are inputs in updating the Venus (VIRA) and Mars (Mars-GRAM) reference atmosphere models based on new data obtained over the last decade and the results of reanalysis of the previous experiments. Special attention is now drawn to Mars, which is in a focus of space probe investigations. Numerical modellings, using Mars general circulation models describe dynamical, thermal and seasonal processes, which take place in the Martian atmosphere. The data obtained in these studies are of interest not only for science, but also for engineering, for planning and designing missions. Some scientific instruments on Mars spacecraft and their scientific goals are presented.
