On Earth, lakes provide favorable environments for the development of life and its preservation as fossils. They are extremely sensitive to climate fluctuations and to conditions within their watersheds. As such, lakes are unique markers of the impact of environmental changes. Past and current missions have now demonstrated that water once flowed at the surface of Mars early in its history. Evidence of ancient ponding has been uncovered at scales ranging from a few kilometers to possibly that of the Arctic ocean. Whether life existed on Mars is still unknown; upcoming missions may find critical evidence to address this question in ancient lakebeds as clues about Mars’ climate evolution and its habitability potential are still preserved in their sedimentary record. Lakes on Mars is the first review on this subject. It is written by leading planetary scientists who have dedicated their careers to searching and exploring the questions of water, lakes, and oceans on Mars through their involvement in planetary exploration, and the analysis of orbital and ground data beginning with Viking up to the most recent missions. In thirteen chapters, Lakes on Mars critically discusses new data and explores the role that water played in the evolution of the surface of Mars, the past hydrological provinces of the planet, the possibility of heated lake habitats through enhanced geothermal flux associated with volcanic activity and impact cratering. The book also explores alternate hypotheses to explain the geological record. Topographic, morphologic, stratigraphic, and mineralogic evidence are presented that suggest successions of ancient lake environments in Valles Marineris and Hellas. The existence of large lakes and/or small oceans in Elysium and the Northern Plains is supported both by the global distribution of deltaic deposits and by equipotential surfaces that may reflect their past margins. Whether those environments were conducive to life has yet to be demonstrated but from comparison with our planet, their sedimentary deposits may provide the best opportunity to find its record, if any. The final chapters explore the impact of climate variability on declining lake habitats in one of the closest terrestrial analogs to Mars at the Noachian/Hesperian transition, identify the geologic, morphologic and mineralogic signatures of ancient lakes to be searched for on Mars, and present the case for landing the Mars Science Laboratory mission in such an environment. First review on the subject by worldwide leading authorities in the field New studies with most recent data, new images, figures, and maps Most recent results from research in terrestrial analogs

The search for life is one of the most active fields in space science and involves a wide variety of scientific disciplines, including planetary science, astronomy and astrophysics, chemistry, biology, chemistry, and geoscience. In December 2016, the Space Studies Board hosted a workshop to explore the possibility of habitable environments in the solar system and in exoplanets, techniques for detecting life, and the instrumentation used. This publication summarizes the presentations and discussions from the workshop.

The Lakes of Mars is a stunning new collection of poems by Chris Orsman that follow on from his most recent book, South: An Antarctic Journey, a sequence about Captain Scott's final expedition to Antarctica. These new poems are a characteristic mix of thoughtful reflection and precise imagery of landscape and object. Chris Orsman captures 'the plainness of life' with a visual clarity, but always pushes his descriptions further, broadening the poems 'into intellectual and moral meaning'. He is also particularly good at vividly recreating historical moments, while evoking the gifts and loss of the past. The first part of The Lakes of Mars encompasses the Wellington hills; a wonderful long poem of the camera and its nostalgia, 'Instamatic'; the light art of Bill Culbert; and 'a total stock of words'. The second and third parts, 'The Lakes of Mars' and 'The Book of the Dead', were inspired by Orsman's 1998 trip to the Antarctic as inaugural recipient of an Artists to Antarctica Fellowship. The New Zealand 'Antarctic' poem is now a settled form, but Orsman was one of its originators and, as these poems prove, a true master of it. The poems in The Lakes of Mars are distinctive, scrupulous, splendid - they have much to offer an attentive reader.

"Sediments and morphological features associated with the martian paleolakes are believed to occur in Valles Marineris, and several large basins including Amazonis, Chryse and Elysium planitia. ... Ice covered lakes can persist even when the mean annual temperatures fall below freezing. Thus, the most recent lacustrine sediments on Mars were probably deposited in ice-covered lakes. ... There is a general consensus among exobiologists that the search for extraterrestrial life should be based upon liquid water. The inference that there was liquid water on Mars during an earlier epoch is the primary motivation for considering the possibility of life during this time. It would be of enormous interest from both an exobiological and paleolimnological perspective to discover lakes or the evidence of former lakes on another planet such as Mars"--P. 1.

Based on topographic, morphologic, and stratigraphic evidence, we propose that ancient water-laid sediment is the dominant component of deposits within Hellas Planitia, Mars. Multiply layered sediment is manifested by alternating benches and scarps visible in Mars Orbiting Camera narrow-angle (MOC NA) images. Viking Orbiter camera and MOC NA images were used to map contacts and stratigraphically order the different materials units within Hellas. Mar's Orbiting Laser Altimeter (MOLA) data reveal that the contacts of these sedimentary units, as well as a number of scarps or other abrupt changes in landscape texture, trace contours of constant elevation for thousands of km, and in one case all around the basin. Channels, consensually interpreted to be cut by water, lead into the basin. MOLA results indicate that the area encompassed by greater Hellas' highest closed contour is nearly one-fifth that of the entire northern plains, making the Hellas 'drainage' area much larger than previously reported. If lakes formed under climatic conditions similar to the modern Martian climate, they would develop thick ice carapaces, then the lakes would eventually sublimate away. Two units within Hellas exhibit a reticulate or honeycomb pattern we speculate are impressions made by lake-lowered ice blocks grounding into initially soft mud.

There have been many books about Antarctica in the past, but all have focused on only one aspect of the continent - its science, its wildlife, the heroic age of exploration, personal experiences or the sheer awesome beauty of the landscape, for example - but none has managed to capture whole story, till now. Gabrielle Walker, author, consultant to New Scientist and regular broadcaster with the BBC has written a book unlike any that has ever been written about the continent. Antarctica weaves all the significant threads into an intricate tapestry, made up of science, natural history, poetry, epic history, what it feels like to be there and why it draws so many different kinds of people back there again and again. It is only when all the parts come together that the underlying truths of the continent emerge. Antarctica is the most alien place on Earth, the only part of our planet where humans could never survive unaided. It is truly like walking on another planet. And yet, in its silence, its agelessness and its mysteries lie the secrets of our past, and of our future.

Battling a climate of waning support for space flight in general and the human exploration of Mars in particular, natural and social scientists, engineers, and other advocates gathered to provide a vehicle for maintaining a continuous dialogue among people in the technical community who were exploring the issue. In 33 papers they discuss planning, surface exploration, transportation concepts, power and fuel systems on Mars, terraforming, and Mars Base concepts for long-term habitation. Abstracts are included for about 90 additional papers. There is no subject index. Annotation copyrighted by Book News, Inc., Portland, OR
