Seventeen wide-ranging essays explore the evolving scientific understanding of Mars, and the relationship between that understanding and the role of Mars in literature, the arts and popular culture. Essays in the first section examine different approaches to Mars by scientists and writers Jules Verne and J.H. Rosny. Section Two covers the uses of Mars in early Bolshevik literature, Wells, Brackett, Burroughs, Bradbury, Heinlein, Dick and Robinson, among others. The third section looks at Mars as a cultural mirror in science fiction. Essayists include prominent writers (e.g., Kim Stanley Robinson), scientists and literary critics from many nations.

Sure to be both an education and revelation for all, "Visions of Mars" takes readers on an extraordinary visual tour of Mars through a selection of dazzling photographs. 209 photos, 199 in full color., including two 8-page gatefolds.

The Apollo 11 astronaut invites young people to evaluate Mars as a potential planet for human colonization, and describes what Mars residents might experience while traveling to and living on the Red Planet.

Can astronauts reach Mars by 2035? Absolutely, says Buzz Aldrin, one of the first men to walk on the moon. Celebrated astronaut, brilliant engineer, bestselling author, Aldrin believes it is not only possibly but vital to America's future to keep pushing the space frontier outward for the sake of exploration, science, development, commerce, and security. What we need, he argues, is a commitment by the U.S. President as rousing as JFK's promise to reach the moon by the end of the 1960 - an audacious, inspiring goal-and a unified vision for space exploration. In Mission to Mars, Aldrin plots that trajectory, stressing that American-led space exploration is essential to the economic and technological vitality of the nation and the world. Do you dare to dream big? Then join Aldrin in his thought provoking and inspiring Mission to Mars.

Buzz Aldrin speaks out as a vital advocate for the continuing quest to push the boundaries of the universe as we know it. As a pioneering astronaut who first set foot on the moon during mankind's first landing of Apollo 11-- and as an aerospace engineer who designed an orbital rendezvous technique critical to future planetary landings -- Aldrin has a vision, and in this book he plots out the path he proposes, taking humans to Mars by 2035. --

Mars has long offered the prospect of another living world near Earth. Although NASA's first spacecraft dashed visions of little green men tending canals, recent voyages have painted a picture of an intriguing planet that may have once resembled Earth, with warmth, water, and possibly life. Mars may answer the great question "Are we alone?"; for if Mars, like Earth, gave rise to life, then trillions of other worlds throughout the universe have surely done the same. Harvard-trained astronomer Ken Croswell set the standard for elegance and eloquence with his stunning photographic triumph, Magnificent Universe. Now, with insightful prose and astonishing images, he presents the red planet's full glory in Magnificent Mars, showing volcanoes taller than Mount Everest, spiral-shaped polar caps of ice, and a canyon system that could stretch from Ohio to California. Here is a concise synthesis of the latest research on Mars, accompanied with the very best full-color images, expertly reprocessed to look even better than NASA's own versions, from the Hubble Space Telescope, Viking, Pathfinder, Mars Global Surveyor, Mars Odyssey, and other spacecraft. Highlights include a foldout panorama of the Martian surface; a never-before-published, rainbow-colored topographic map; and a sequence showing a full rotation of Mars, courtesy of the Hubble Space Telescope. Many of these images have never appeared in a book before. Few have ever looked so good. In lyrical prose, Dr. Croswell weaves these stupendous images into a virtual tour of Mars by organizing them around the four elements -- Earth, Air, Fire, and Water. From the northern plains of Vastitas Borealis to the towering Olympus Mons and other volcanoes of the Tharsis bulge, we explore the red planet's geology, topography, and surface. From the frigid climate to the massive dust storms that can engulf the entire globe, we examine the thin Martian atmosphere and the clues it preserves to the planet's wetter past. And, from the flood channels that spill into Chryse Planitia to the vast potential lakebed of ancient Hellas, we see stunning images of ancient rivers and floods, triggering speculation that a warm, wet Mars may have given rise to life that survives to this day. The tour concludes with a voyage to the planet's two potato-shaped moons, Phobos and Deimos, complete with rainbow-colored topographic maps. Unique color-coded tables on Mars, its atmosphere, its life history, its moons, and NASA missions to the planets appear in a useful reference section, along with a glossary and suggestions for further reading. With its large format, superb images, and compelling text, Magnificent Mars is the next best thing to standing on the red planet itself. In future years NASA will launch numerous missions to Mars, and Magnificent Mars is the definitive guide to what these spacecraft will see. Indeed, the first human explorers to Mars may want to take a copy of Magnificent Mars aboard their spaceship.

In spring 2011 the National Academies of Sciences, Engineering, and Medicine produced a report outlining the next decade in planetary sciences. That report, titled Vision and Voyages for Planetary Science in the Decade 2013-2022, and popularly referred to as the "decadal survey," has provided high-level prioritization and guidance for NASA's Planetary Science Division. Other considerations, such as budget realities, congressional language in authorization and appropriations bills, administration requirements, and cross-division and cross-directorate requirements (notably in retiring risk or providing needed information for the human program) are also necessary inputs to how NASA develops its planetary science program. In 2016 NASA asked the National Academies to undertake a study assessing NASA's progress at meeting the objectives of the decadal survey. After the study was underway, Congress passed the National Aeronautics and Space Administration Transition Authorization Act of 2017 which called for NASA to engage the National Academies in a review of NASA's Mars Exploration Program. NASA and the Academies agreed to incorporate that review into the midterm study. That study has produced this report, which serves as a midterm assessment and provides guidance on achieving the goals in the remaining years covered by the decadal survey as well as preparing for the next decadal survey, currently scheduled to begin in 2020.
