From a long-term planning lead for the Mars Exploration Rover Project comes this vivid insider account of some of NASA’s most vital and exciting missions to the Red Planet, illustrated with full-color photographs—a wondrous chronicle of unprecedented scientific discovery and the search for evidence of life on Mars. “There are probably just a few of moments in human history when a small group of humans stood on the margins of a vast new world, and it is no stretch of the romantic imagination that the arrival of two rovers on the surface of another planet was surely one of them.” Human exploration of Mars is the most ambitious and exciting scientific goal of the twenty-first century. Few people know as much about this fascinating planet as Dr. Larry Crumpler. As one of the long-term planning leads for the Mars Exploration Rover Project, he helped control the daily communications between NASA and the rovers roaming the planet to gather scientific data. Thanks to the Rover Project, we now know that the dry, red dust of the planet’s surface hides a wet, possibly living history, and that conditions were present for the evolution of complex, organic life. In this magnificent compendium, Dr. Crumpler recounts the history of the Red Planet, from the earliest days when ancient astronomers turned their eyes to the heavens to the breakthrough discoveries being unearthed by modern technology today, including some of the first images from the latest rover, Perseverance. Paired with stunning, full-color photographs taken by rovers and NASA satellites images, this magnificent “biography” of the red planet allows us to understand and experience it as never before. When the Spirit and Opportunity Rovers landed on Mars in January 2004, scientists expected them to function for 90 days. But those three months turned into fifteen years. With data gathered by the rovers, Dr. Crumpler and his fellow team members were able to reconstruct the planet’s stunning geological past, when it was once inundated with water, and perhaps could have supported microbial life. Dr Crumpler also reveals the joys and demands of life as a scientist taking part in these historic missions. Exploring fundamental questions about this remarkable planet that have intrigued us earthlings for years, Missions to Mars illuminates Mars’ significance in the solar system—and the human imagination.

This is the comprehensive story of NASA’s pioneering Mars 2020 mission, which at this moment continues to break ground on the surface of the Red Planet. The book takes readers through every stage of the Mars mission, describing its major goals and objectives, the cutting-edge technology and instrumentation onboard the Perseverance rover and other spacecraft components, and the members of the scientific team who steered the mission along the way. Mars 2020 is the first to actually take samples of the Red Planet and prepare them for subsequent return to Earth. The chapters therefore delve into how and why Jezero Crater was selected as the optimal landing and sample collecting site to meet the mission objectives. Featuring dozens of high-resolution images of the mission, this book gives readers a deeper understanding of the technology underlying Mars 2020 and why its work is so important for planetary science and space exploration.

With authoritative text and NASA photography and artworks, NASA Missions to Mars tells the story of NASA’s programs to explore the Red Planet—from the first tentative flybys to the present—and offers a glimpse into the future of Mars exploration.

For centuries humankind has fantasized about life on Mars, whether it’s intelligent Martian life invading our planet (immortalized in H.G. Wells’s The War of the Worlds) or humanity colonizing Mars (the late Ray Bradbury’s The Martian Chronicles). The Red Planet’s proximity and likeness to Earth make it a magnet for our collective imagination. Yet the question of whether life exists on Mars—or has ever existed there—remains an open one. Science has not caught up to science fiction—at least not yet. This summer we will be one step closer to finding the answer. On August 5th, Curiosity—a one-ton, Mini Cooper-sized nuclear-powered rover—is scheduled to land on Mars, with the primary mission of determining whether the red planet has ever been physically capable of supporting life. In Getting to Mars, Roger Wiens, the principal investigator for the ChemCam instrument on the rover—the main tool for measuring Mars’s past habitability—will tell the unlikely story of the development of this payload and rover now blasting towards a planet 354 million miles from Earth. ChemCam (short for Chemistry and Camera) is an instrument onboard the Curiosity designed to vaporize and measure the chemical makeup of Martian rocks. Different elements give off uniquely colored light when zapped with a laser; the light is then read by the instrument’s spectrometer and identified. The idea is to use ChemCam to detect life-supporting elements such as carbon, nitrogen, and oxygen to evaluate whether conditions on Mars have ever been favorable for microbial life. This is not only an inside story about sending fantastic lasers to Mars, however. It’s the story of a new era in space exploration. Starting with NASA’s introduction of the Discovery Program in 1992, smaller, scrappier, more nimble missions won out as behemoth manned projects went extinct. This strategic shift presented huge opportunities—but also presented huge risks for shutdown and failure. And as Wiens recounts, his project came close to being closed down on numerous occasions. Getting to Mars is the inspiring account of how Wiens and his team overcame incredible challenges—logistical, financial, and political—to successfully launch a rover in an effort to answer the eternal question: is there life on Mars?

In the next decade, NASA, by itself and in collaboration with the European Space Agency, is planning a minimum of four separate missions to Mars. Clearly, exciting times are ahead for Mars exploration. This is an insider’s look into the amazing projects now being developed here and abroad to visit the legendary red planet. Drawing on his contacts at NASA and the Jet Propulsion Laboratory, the author provides stunning insights into the history of Mars exploration and the difficulties and dangers of traveling there. After an entertaining survey of the human fascination with Mars over the centuries, the author offers an introduction to the geography, geology, and water processes of the planet. He then briefly describes the many successful missions by NASA and others to that distant world. But failure and frustration also get their due. As the author makes clear, going to Mars is not, and never will be, easy. Later in the book, he describes in detail what each upcoming mission will involve. In the second half of the book, he offers the reader a glimpse inside the world of Earth-based "Mars analogs," places on Earth where scientists are conducting research in hostile environments that are eerily "Martian." Finally, he constructs a probable scenario of a crewed expedition to Mars, so that readers can see how earlier robotic missions and human Earth simulations will fit together. All this is punctuated by numerous firsthand interviews with some of the finest Mars explorers of our day, including Stephen Squyres (Mars Exploration Rover), Bruce Murray (former director of the Jet Propulsion Laboratory), and Peter Smith (chief of the Mars Phoenix Lander and the upcoming OSIRIS-REx missions). These stellar individuals give us an insider’s view of the difficulties and rewards of roaming the red planet. The author’s infectious enthusiasm and firsthand knowledge of the international space industry combine to make a uniquely appealing and accessible book about Mars.

This book describes the most complex machine ever sent to another planet: Curiosity. It is a one-ton robot with two brains, seventeen cameras, six wheels, nuclear power, and a laser beam on its head. No one human understands how all of its systems and instruments work. This essential reference to the Curiosity mission explains the engineering behind every system on the rover, from its rocket-powered jetpack to its radioisotope thermoelectric generator to its fiendishly complex sample handling system. Its lavishly illustrated text explains how all the instruments work -- its cameras, spectrometers, sample-cooking oven, and weather station -- and describes the instruments' abilities and limitations. It tells you how the systems have functioned on Mars, and how scientists and engineers have worked around problems developed on a faraway planet: holey wheels and broken focus lasers. And it explains the grueling mission operations schedule that keeps the rover working day in and day out.
