Book Description
Nearly five billion years ago, Earth and Mars were born together as planetary siblings orbiting a young, emerging Sun. Yet today, one planet is water rich and life bearing, while the other is seemingly cold, dry, and forbidding. Earth and Mars is a fusion of art and science, a blend of images and essays celebrating the successful creation of our life-sustaining planet and the beauty and mystery of Mars. Through images of terrestrial landscapes and photographs selected from recent NASA and European Space Agency missions to Mars, Earth and Mars reveals the profound beauty resulting from the action of volcanism, wind, and water. The accompanying text provides a context for appreciating the role of these elemental forces in shaping the surfaces of each planet, as well as the divergent evolutionary paths that led to an Earth that is teeming with life, and Mars that is seemingly lifeless. Earth and Mars inspires reflection on the extraordinarily delicate balance of forces that has resulted in our good fortune: to be alive and sentient on a bountiful blue world.

Book Description
"Mars and Earth share many features. Maybe one day, cities full of people will be another thing they share! But how similar are the planets, really? Which features aid in supporting human life, and which will make colonization more difficult? Find out what kinds of preparations are underway to make living on Mars possible. Full-color photos give readers a look at this future vacation destination. 21st Century sidebars discuss technological advancements, hypothesize future endeavors and inventions, and solve problems and challenges astronauts might face.

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
The Space Studies Board of the National Research Council (NRC) serves as the primary adviser to the National Aeronautics and Space Administration (NASA) on planetary protection policy, the purpose of which is to preserve conditions for future biological and organic exploration of planets and other solar system objects and to protect Earth and its biosphere from potential extraterrestrial sources of contamination. In October 1995 the NRC received a letter from NASA requesting that the Space Studies Board examine and provide advice on planetary protection issues related to possible sample-return missions to near-Earth solar system bodies.

Book Description
“A handsome and engaging children’s book. . . . This accessible look at interplanetary exploration will appeal to a broad range of young space enthusiasts.” —Publishers Weekly (starred review) On August 6, 2012, the rover Curiosity touched down on the rocky surface of Mars—and now she’s ready to guide you through her journey. From idea to creation and beyond, this fact-filled, stylish book introduces readers to Curiosity and her mission: to discover more about the red planet and search for evidence of life. How did Curiosity get her name? What tools does she use to carry out her tasks? The popular NASA rover narrates how and why she traveled more than 350,000,000 miles to explore a planet no human has ever visited . . . and what she has been doing there for the past decade or so. Markus Motum brings Curiosity’s story to life in vivid color: the deep blues of space set off the warm, rusted hues of Mars’s dusty red surface, marking this lovable rover and her mission as something special—truly a world apart.

Book Description
Recent spacecraft and robotic probes to Mars have yielded data that are changing our understanding significantly about the possibility of existing or past life on that planet. Coupled with advances in biology and life-detection techniques, these developments place increasing importance on the need to protect Mars from contamination by Earth-borne organisms. To help with this effort, NASA requested that the NRC examine existing planetary protection measures for Mars and recommend changes and further research to improve such measures. This report discusses policies, requirements, and techniques to protect Mars from organisms originating on Earth that could interfere with scientific investigations. It provides recommendations on cleanliness and biological burden levels of Mars-bound spacecraft, methods to reach those levels, and research to reduce uncertainties in preventing forward contamination of Mars.

Book Description
From Habitability to Life on Mars explores the current state of knowledge and questions on the past habitability of Mars and the role that rapid environmental changes may have played in the ability of prebiotic chemistry to transition to life. It investigates the role that such changes may have played in the preservation of biosignatures in the geological record and what this means for exploration strategies. Throughout the book, the authors show how the investigation of terrestrial analogs to early Martian habitats under various climates and environmental extremes provide critical clues to understand where, what and how to search for biosignatures on Mars. The authors present an introduction to the newest developments and state-of-the-art remote and in situ detection strategies and technologies that are being currently developed to support the upcoming ExoMars and Mars 2020 missions. They show how the current orbital and ground exploration is guiding the selection for future landing sites. Finally, the book concludes by discussing the critical question of the implications and ethics of finding life on Mars. - Edited by the lead on a NASA project that searches for habitability and life on Mars leading to the Mars 2020 mission - Presents the evidence, questions and answers we have today (including a summary of the current state of knowledge in advance of the ESA ExoMars and NASA Mars 2020 missions) - Includes contributions from authors directly involved in past, current and upcoming Mars missions - Provides key information as to how Mars rovers, such as ExoMars and Mars 2020, will address the search for life on Mars with their instrumentation

Book Description
The search for life on Mars—and the moral issues confronting us as we prepare to send humans there Does life exist on Mars? The question has captivated humans for centuries, but today it has taken on new urgency. As space agencies gear up to send the first manned missions to the Red Planet, we have a responsibility to think deeply about what kinds of life may already dwell there—and whether we have the right to invite ourselves in. Telling the complete story of our ongoing quest to answer one of the most tantalizing questions in astronomy, David Weintraub grapples with the profound moral and ethical questions confronting us as we prepare to introduce an unpredictable new life form—ourselves—into the Martian biosphere. Now with an afterword that discusses the most recent discoveries, Life on Mars explains what we need to know before we go.
