Book excerpt: This is the first book to deal with Titan, one of the most mysterious bodies in the solar system. The largest satellite of the giant planet Saturn, Titan is itself larger than the planet Mercury, and is unique in being the only known moon with a thick atmosphere. In addition, its atmosphere bears a startling resemblance to the Earth's, but is much colder. The American and European space agencies, NASA and ESA, have recently combined efforts to send a huge robot spacecraft to orbit Saturn and land on Titan. This book provides the background to this, the greatest deep space venture of our time, and sets the scene for what may be found when the spacecraft arrives in 2004.
Download or read book Titan written by Athena Coustenis and published by World Scientific. This book was released on 2008 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Titan: Exploring an Earthlike World presents the only comprehensive description in book form of what is currently known about Titan, the largest satellite of the planet Saturn and arguably the most intriguing and mysterious world in the Solar System. Because of its resemblance to our own planet, Titan is often described as a “frozen primitive Earth” and is therefore of wide interest to scientists and educated laypersons from a wide range of backgrounds. The book aims to cater to all of these by using nontechnical language wherever possible, while maintaining a high standard of scientific rigor.The book is a fully revised and extensively updated edition of Titan: The Earthlike Moon, which was published in 1999, before the Cassini and Huygens missions arrived to orbit Saturn and land on Titan. As investigators on these missions, the authors use the latest results to present the most recent revelations and latest surprises about an exciting new world.

Book excerpt: Titan, the largest of Saturn's moons, shares remarkable similarities with Earth. Its thick atmosphere is composed primarily of nitrogen; it features the most complex organic chemistry known outside of Earth and, uniquely, hosts an analog to Earth's hydrological cycle, with methane forming clouds, rain and seas. Using the latest data from the ongoing Cassini-Huygens missions, laboratory measurements and numerical simulations, this comprehensive reference examines the physical processes that shape Titan's fascinating atmospheric structure and chemistry, weather, climate, circulation and surface geology. The text also surveys leading theories about Titan's origin and evolution, and assesses their implications for understanding the formation of other complex planetary bodies. Written by an international team of specialists, chapters offer detailed, comparative treatments of Titan's known properties and discuss the latest frontiers in the Cassini-Huygens mission, offering students and researchers of planetary science, geology, astronomy and space physics an insightful reference and guide.
Download or read book Radiation And Dynamics In Titan s Atmosphere Investigations Of Titan s Present And Past Climate written by Juan Manuel Lora and published by . This book was released on 2014 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation explores the coupling between radiative and three-dimensional dynamical processes in the atmosphere of Titan, and their impact on the seasonal climate and recent paleoclimate. First, a simple calculation is used to demonstrate the atmospheric attenuation on the distribution of insolation. The maximum diurnal-mean surface insolation does not reach the polar regions in summertime, and this impacts both surface temperatures and their destabilizing effect on the atmosphere. Second, a detailed two-stream, fully non-gray radiative transfer model, written specifically for Titan but with high flexibility, is used to calculate radiative fluxes and the associated heating rates. This model reproduces Titan's temperature structure from the surface through the stratopause, over nearly six decades of pressure. Additionally, a physics parameterizations package is developed for Titan, in part based on similar methods from Earth atmospheric models, for use in a Titan general circulation model (GCM). Simulations with this model, including Titan's methane cycle, reproduce two important observational constraints---Titan's temperature profile and atmospheric superrotation---that have proven difficult to satisfy simultaneously for previous models. Simulations with the observed distribution of seas are used to examine the resulting distribution of cloud activity, atmospheric humidity, and temperatures, and show that these are consistent with dry mid- and low-latitudes, while the observed polar temperatures are reproduced as a consequence of evaporative cooling. Analysis of the surface energy budget shows that turbulent fluxes react to the surface insolation, confirming the importance of its distribution. Finally, the GCM is used to simulate Titan's climate during snapshots over the past 42 kyr that capture the amplitude range of variations in eccentricity and longitude of perihelion. The results show that the atmosphere is largely insensitive to orbital forcing, and that it invariably transports methane poleward, suggesting Titan's low-latitudes have been deserts for at least hundreds of thousands of years. In detail, seasonal asymmetries do affect the distribution of methane, moving methane to the pole with the weaker summer, though orbital variations do not imply a long-period asymmetry. If the timescale for the atmosphere to transport the surface liquid reservoir is sufficiently short, this explains the observed north-south dichotomy of lakes and seas.

This book was released on 2013-12-11 with total page 3529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advancements in science and engineering have occurred at a surprisingly rapid pace since the release of the seventh edition of this encyclopedia. Large portions of the reference have required comprehensive rewriting and new illustrations. Scores of new topics have been included to create this thoroughly updated eighth edition. The appearance of this new edition in 1994 marks the continuation of a tradition commenced well over a half-century ago in 1938 Van Nostrand's Scientific Encyclopedia, First Edition, was published and welcomed by educators worldwide at a time when what we know today as modern science was just getting underway. The early encyclopedia was well received by students and educators alike during a critical time span when science became established as a major factor in shaping the progress and economy of individual nations and at the global level. A vital need existed for a permanent science reference that could be updated periodically and made conveniently available to audiences that numbered in the millions. The pioneering VNSE met these criteria and continues today as a reliable technical information source for making private and public decisions that present a backdrop of technical alternatives.

Download or read book A Study of Mid Latitude Clouds in Saturn s Moon Titan written by Tersi Marcela Arias-Young and published by . This book was released on 2021 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Saturn's largest moon, Titan, provides a new perspective on planetary climate. It is larger than Mercury, has a 16-day rotation period, 29.5-year annual cycle, and a ~1.5-bar nitrogen atmosphere. Titan has a fully developed atmosphere, analogous to that of Earth, and methane plays a similar role to water in the hydrological cycle on our planet, generating clouds, storms and precipitation. Titan's clouds have been under investigation since their detection in 1995 with ground-based telescopes and were observed in detail during the Cassini-Huygens mission to the Saturn system. "Cassini" orbited Saturn and its moons from 2004 to 2017, giving unparalleled views that have led to countless discoveries and clouds are one of many fascinating Titan phenomena revealed by it. To this day, cloud formation mechanisms, dynamics and duration of the associated storms are still not fully understood and are the subject of ongoing study. The central goal of this work is to provide a general physical interpretation of observed storms and their relation to atmospheric dynamics of the moon. Two previous studies are the foundation for this research: Mitchell et al. (2011), who developed a process for interpreting Titan's cloud morphologies and precipitation through a combined analysis of observations and general circulation model (GCM) simulations; and Turtle et al. (2011), who reported the first evidence of seasonal changes on the moon obtained from Cassini cloud data. This dissertation presents a survey of Titan's mid-latitude clouds, as seen from space by the Cassini Imaging Science Subsystem (ISS) instrument, compares a subset of the observed clouds to the methane storms produced in a climate model of Titan, and infers the underlying storm dynamics by connecting the two. ISS is a multi-wavelength - ultraviolet to near-infrared - camera specifically designed to take high resolution images from the top of the atmosphere to the surface of Titan piercing through the thick haze located in the stratospheric layer of the moon, which typically blocks the view of tropospheric clouds underneath it. This study starts with an analysis of the physics of clouds applied to Titan's conditions and a microphysical cloud scheme to show how the abundant haze particles in the atmosphere are likely the seeds for methane droplets that catalyze cloud formation. Next, the ISS image archive is searched for cloud phenomena and various types of storms are surveyed. This is followed by Image processing, that require the conversion of raw images into maps with global locations of the clouds and the production of enhanced views of cloud features against the surface background to reveal their morphology. We then search for storms with temporally resolved observations and use their spatio-temporal distributions to identify the atmospheric dynamics behind them, including Rossby and gravity waves. Although many clouds/storms are identified, only two of them provide clear spatial and temporal information that allow this type of analysis. The manuscript then pivots to analysis of methane storms in model simulations of Titan's climate using the Titan Atmosphere Model (TAM; Lora et al. 2015) with full surface hydrology (Faulk et al., 2019). The spatio-temporal features of observed clouds combined with the simulated storms at the same season as the observations suggest that just as waves organize storms on Earth, they do so on Titan as well. The results of the study strongly indicate that Titan's cloud formation and propagation are associated with Rossby and equatorial Kelvin waves, and perhaps combinations thereof, and that the clouds/storms can persist for weeks and perhaps much longer as they propagate around the moon's globe - a phenomenon referred to in this work as "persistence". These findings offer a glance into the complex phenomenology, dynamics and persistence of Titan's clouds. The methodology developed in the course of this work for comparing the spatio-temporal distribution of observed clouds to analog storms in TAM is novel, while also being consistent with previous studies focused either on the spatial distribution or seasonal evolution of observed clouds. Future missions to Titan, including the funded Dragonfly mission, will facilitate further model-data comparisons, for instance the long-term persistence of the Kelvin wave in TAM. This methodology, documented in detail in a "cookbook", provides a set of useful tools and guidance for future explorations of the clouds and storms of Titan.
