Editorial Reviews

Publishers Weekly
As Pyle (Destination Moon) points out, Mars is a “planet of dreams,” provoking fantasies about aliens and busy canals. Advances in technology over the past 50 years, however, have given us a more accurate if equally vivid insight into the red planet. Pyle’s time line of Mars exploration introduces both the missions and the scientists and engineers behind them, such as musician-turned-planetary geologist Jeffrey Plaut and Rob Manning, Pathfinder’s chief engineer and online NASA star. The tour begins with the space probe Mariner 4, which in 1965 captured the first closeup images of “a dry, barren place festooned with craters.” Pyle goes on to describe how later flybys revealed old volcanoes, evidence of wind erosion, and most surprising, gullies, streambeds, and canyons—signs that there had once been moving water on Mars. Succeeding missions sampled soil and delivered more revealing pictures of Mars’s surface. Later robot explorers like Spirit, Opportunity, and Phoenix carried more advanced onboard labs to search for water and evidence of microbial life. As the souped-up Curiosity rover preps for landing later this year, with the capacity to take 3D photos and HD video, Pyle gives readers a workmanlike, enlightening crash course in Mars research and exploration.

From the Publisher
"Destination Mars brings to life an extraordinary part of human exploration—the preliminary reconnaissance of the planet of dreams over the last fifty years. Enlivened by interviews with many of the participants, Destination Mars makes you feel as if you are exploring the planet with them."
-Steven J. Dick, Former NASA chief historian

"The enigmatic Red Planet does not easily give up its secrets. Yet Destination Mars takes the reader on a first-class journey to this new world, one that continues to be a magnet for inquisitive scientists and space engineers. This is a superb, fact-filled, up-to-date book that portrays the legacy of spacecraft and personalities—from cheerleaders to unsung heroes—that have opened up the terra incognito that is Mars to extraordinary exploration."
-Leonard David, Space Insider columnist, SPACE.com

"Mars has long held a special fascination for Americans, perhaps it might even be a planet that harbors life. Rod Pyle has written a fine account of this fascination, outlining the history of the robotic space probes sent to the Red Planet and the knowledge gained through these expeditions."
-Roger D. Launius, Senior curator, Division of Space History, National Air and Space Museum, Smithsonian Institution

"[A]n optimistic, enthusiastic survey of humanity’s ongoing duel of wits with our neighbor planet. Interviews with some of the people involved in Mars missions show the thread of curiosity and wonder connecting the Mars exploration projects of the last fifty years. Getting to Mars has been really difficult, but for Rod Pyle the problems just make it more interesting and worthwhile."
-Stephen Fentress, Director, Strasenburgh Planetarium, Rochester Museum & Science Center

Library Journal

Chapter One

THE FIRST MARTIAN

July 20, 1976: The Viking 1 orbiter instructed its lander to begin the separation sequence to start the long journey to the Martian surface. It was just after midnight at the Jet Propulsion Laboratory (JPL) in Pasadena, but as the probe was automated, no commands had been exchanged for some time. The onboard computer initiated a final round of systems checks. The explosives that joined the lander to the orbiter were armed ...

Anxious flight controllers, largely powerless at this distance, could only watch the time-delayed data as the onboard computers made their own decisions. At 00:00 onboard computers fired the pyrotechnics, separating the Viking lander, which soon fired its own braking thrusters to begin the slow fall out of Martian orbit. In the dusky skies above, the orbiter from which it had recently separated continued on its mission. Below spread the ruddy expanse of Mars: dusty, cold, unexplored ... and in about three and a half increasingly turbulent hours, home.

The Viking 1 lander, at ten feet wide by seven feet tall, was part of the largest and most expensive US unmanned mission to date. The orbiter, eight feet wide and ten tall, with a solar-panel span of thirty-two feet, shared the distinction. In a few weeks, Viking 2, a virtual twin, would arrive on Mars on an identical mission, but within a different landing zone on the opposite side of the planet.

The people who had sent Viking to this dangerous rendezvous waited out the landing confirmation signal in tense quiet. Only the most necessary words were spoken. There was an eighteen-minute delay between Earth and Mars at this distance; whatever happened to Viking now would be of its own doing. Many scientists on this program estimated a 50-50 chance of success, even with two landers. It was, in essence, a blind landing on a rocky, undulating landscape.

The Viking 1 lander was, for the first time in its short life, completely alone.

The tiny craft plummeted into the thin Martian atmosphere at 10,000 mph, still firing its braking thrusters. These rockets were models of simplicity. The fuel was a monopropellant and needed no ignition source and no other chemical mixed with it to explode into thrust. Further, instead of using complex pumps to feed the engine, the propellants were pressurized by stored helium gas. There was little to go wrong once they fired.

The lander was encased by a heat-resistant aeroshell, a dish-shaped structure that protected it from the heat of entry but also placed more demands upon its small digital brain. For as it plummeted through the upper reaches of the tenuous Martian atmosphere, Viking's computer was focused not just on a successful landing but also on conducting research in this wispy environment. Nothing is wasted in space exploration, and this early descent phase was no exception. As the computer labored to steer the craft, data began flowing in from sensors mounted on the aeroshell, providing data about charged particles surrounding the descending craft. Within the parade of arcane obsessions in the mind of the planetary scientist, understanding how the solar wind—high-energy particles streaming forth from the sun—interacts with the upper reaches of the Martian atmosphere is a thrill. The measurements now being recorded on the onboard tape drives should shed some light on this question. But Viking cared not; it simply stored the data for eventual delivery to Earth. Recording data was its raison d'être, and to this task it applied itself from its first moments.

At about 180 miles in altitude, another instrument switched on: the mass spectrometer. This would measure the makeup of the upper atmosphere, analyzing the thin gasses present to provide a more detailed accounting of the "air" to augment the painstakingly gathered information already gleaned from Earth-bound telescopes. This first US spacecraft to enter another planet's atmosphere would accomplish multiple objectives, but primary among them was searching for one capable of supporting life as we understood it in 1976.

At about sixty miles high, this group of instruments switched off and another set became active. These performed an elegant analysis of the pressure, density, and temperature of the lower atmosphere by measuring the slowing of the craft. It was a bit like a waltz with a nonexistent partner, where one's success is measured via self-observation rather than direct feedback from the surroundings. But it was enough.

At about seventeen miles, the trajectory shifted: the aeroshell was sufficiently aerodynamic that it began to generate some lift, and Viking began to glide across the Martian sky. All this was by design; it was another way to scrub off excess velocity. Eventually, weight and drag took their toll and the craft began its steep descent once more.

The continual hiss of the rockets was joined by the roar of the thickening atmosphere, which, while thin, would soon be enough for the single parachute, set to deploy at nineteen thousand feet, to slow the machine sufficiently to land in one piece. This slowing to a sane rate of descent would be aided by more rocket engines. These were ingeniously designed as three clusters of eighteen tiny nozzles that would provide adequate braking propulsion without disturbing the surface upon which it alighted. All this, plus the fanatical sterilization of the spacecraft, was critical to preserving the sanctity of the ground below. For this was central to its primary mission—the search for life.

The onboard radar was scanning the ground, providing excellent data for range to the surface. What it was not providing was any idea of how rough that surface might be. The Viking team back on Earth had searched for the best landing place it could find with Mariner 6 and 7 photographic surveys, and later with results from Mariner 9, but it was barely better than a rough guess. At the Mariner 9 camera resolutions, the best images heretofore available, items smaller than the Rose Bowl were nearly invisible. Anything smaller than that had to be inferred from the analysis of surrounding terrain, and this was more alchemy than science, based on Earth-bound geological assumptions. Teams had agonized over these images for years. Then, data from the just-arrived Viking orbiter cameras resulted in more eleventh-hour angst about the landing area and a new site was selected at the last moment. Now all JPL controllers could do was aim the gun, close their eyes, and squeeze the trigger. In short, Viking was what lab folk later referred to as a BDL—a Big, Dumb Lander. Much of what happened from now on was based on luck. Viking could crash and mission control would be blissfully unaware until eighteen minutes after the fact, when the signal would simply vanish.

Soon the lander unhooked from the parachute, now relying only on its tiny landing rockets to control the final descent. At three hundred feet up, low-level radar kicked in to give a last set of readings. At sixty feet, the computer worked to cancel any horizontal motion and the lander settled into a strictly downward mode. It would now land directly below, no matter what. So said the simple instructions burnt into its primitive memory, saved in tiny magnetic cores that lived at the intersection of minute, hair-thin wires. While brutishly dumb by today's standards (your toaster probably holds more data), it was an elegant and almost bombproof method of storing data.

Slowly, Viking descended the final few feet. The rockets would not shut off until the lander made ground contact. But what lay below? The Viking lander had a scant 8.5 inches of ground clearance; any rock larger than that would likely end the mission. Falling in the weak gravity at a leisurely 6 mph, about the speed a person can walk, Viking 1 settled onto Chryse Planitia, Greek for "Golden Plain," a large and relatively flat expanse not far from the Tharsis volcanic region.

Touchdown. Silence returned to Mars. The Viking 1 lander was down, alive and well, after a 440,000,000-mile journey.

The date was July 20, 1976, the seventh anniversary of the landing of Apollo 11 on the moon. It was the first US soft landing on another planet (a moon is a satellite), and the first probe to function for more than a minute on another planetary body (an earlier Soviet probe had landed, but failed upon touchdown). In fact, it would perform well beyond its builders' wildest expectations.

As the lander began surface operations, the Viking orbiter continued overhead, entering a new phase of its own science program. Armed with high-resolution cameras, it continued its observations while also acting as a relay station between the lander below and Earth, a blue star barely visible over the horizon.

Lander 1 went through a deliberate cycle of making sure that the descent engines and associated systems were shut down. It would not do to drip anything caustic or polluting onto the ground below. Hydrazine, the craft's volatile and corrosive fuel, would not be friendly to any microorganisms lurking about and would be a terrible way of saying hello. In fact, not so much as a microbe of Earth biota had been knowingly allowed to fester on Viking either; it had been baked, purged, and sterilized better than any surgeon's tool before launch. Nothing could be allowed to pollute the virgin Martian soil. As the engines were "safed," the computer queried the navigation system, or inertial guidance unit. This simple system, while no longer needed for steering the craft, would help to supply altitude and directional information, so it was run for another five minutes. This information was critical to aiming the radio dish toward Earth, so the more accurate the data, the better.

At the same time, the first postcard to home was being assembled. The Viking landers used a new type of imaging camera. Previous space probes had used state-of-the-art TV cameras, but at the time, the images were not up to what the designers had yearned for. For Viking, the camera stared upward into a mirror that swung vertically, "nodding" up and down. Between each nod the mirror would rotate a small amount. In this way, a series of strips were assembled over time, and these resulted in what was, for the day, a very high-resolution image. Two of these ingenious devices were mounted on each lander, allowing three-dimensional imaging, and the first job of the day was to send an image home.

But this first snapshot of another planet was not to be a splendid panoramic of the landing area; rather, it was a somewhat mundane image of the nearest footpad. This would accomplish multiple goals instantaneously: the safety (or lack thereof) of the landing site would be demonstrated by the placement of the footpad. The amount of sinking into the sandy soil (properly called regolith, as the word soil implies life within) would be shown, and this, along with other measurements such as the amount of slowing at contact and the designed-in collapsing of the lander's legs upon touchdown would supply information about the compactibility of the ground. Remember, nothing is wasted in space exploration.

Back on Earth, strips of the first picture from Mars began to come in. It was innocuous enough: a shot of footpad 3. If the probe had failed then and there, a lot of folks would have been very upset to have nothing more to show for the billion-dollar effort. But this shot was needed to ensure that the craft was stable. Cheers rang out at JPL and Caltech as the proof of a successful landing were made visible. But from Mars, the lander could not hear, nor would it have cared. It merely carried on in its eighteen kilobytes of programmed duties with dogged and ruthless determination.

Next on the lander's to-do list were the pyrotechnic events, known to most of us as explosions. In spaceflight, whether manned or unmanned, small explosives had long had a leading role. Then as now, they were used to separate the stages of rockets as they ascended away from Earth. They released spacecraft once in orbit. They opened and closed valves. And, in Viking's case, they were critical to beginning Mars-based activities. These are, by their nature, one-shot operations-as in, they work or they don't. Their duties included releasing safeties for the life-science experiments and opening the meteorology boom-an arm with instruments to measure wind speed, temperature, and the like. These performed without a hitch.

Now a second photo was taken, and this was the money shot: the first picture of the horizon of Chryse Planitia. As the lander went about its business, breath was again held in mission control. What would we see? What did the surface of Mars look like at ground level? Remember that these were the days of rotary telephones, bias-ply tires, and such state-of-the-art things as The Eagles: Greatest Hits via vinyl records. An image from the surface of Mars was heady stuff. And with the Viking orbiter disappearing over the horizon in about twelve minutes, and with it, the best link to home, this had to be done now.

Once again, Viking 1 did not disappoint. The first image, black and white but glorious nonetheless, slowly assembled, again, a strip at a time. The tension broke slightly as the first strip came in, but like a good mystery novel, Mars was only revealed a small bit at a time. The results were well worth the wait. After years of preparation, a billion dollars, and a journey of many times the 119 million miles then separating Earth from Mars, the first landscape was in. The data was still coming back long after the orbiter was out of touch, given the long transmission travel time across the vast darkness, and the lander went into a base-operation mode while out of communication.

But the picture ... oh, that second picture. It lacked color and was obscured on the bottom by various parts of the spacecraft. But there it was, in all its monochromatic glory: the horizon of Mars. Low, arid hills were off in the distance, and between the lander and those hills was an expanse of sharp, jagged rocks. Hundreds of them. And off to the right, dominating the horizon there, was the bright glow of the sun, unseen and above the frame. It was a dry, cloudless spectacle. For someone seeking the serenity of an English tea garden, or the Mars of Percival Lowell, it would not do. But for any human pining for a glimpse of another world, a world we could relate to, another planet to which we might one day travel, it was nirvana.

Viking 1 was, however, oblivious to such human emotion. The outbursts and cheers from Earth remained unheard. It had a primary mission of just sixty days on the surface, with an extended mission target of 120. At that point, Mars would pass behind the sun and communication would be lost for weeks. And while controllers on Earth planned to "safe" the lander during this time, their confidence in reawakening the machine after this period was limited. But true to what would become JPL's legacy of performing near miracles with distant machines, the first lander operated successfully for well over six years. And the tale of its ultimate demise is not one of equipment failure, but of human error.

With Viking's successful landing, there was now time—well over two months in the primary mission alone—to perform the tasks it was designed to do. The instructions came up from Earth in carefully coded batches, to be processed and executed in sequence. With mechanical exactitude, Viking 1 began its primary labors—taking color images of the surrounding surface, digging scoops of soil and dumping them carefully into small funnels that led to an onboard laboratory, and fulfilling its primary objective: the search for life on Mars.

Just under two months later, on September 3, 1976, the Viking 2 lander settled gently onto Utopia Planitia, 4,200 miles away to the northeast. Humanity now had two outposts on Mars, and the exploration of the red planet began in earnest. Overhead, the Viking orbiters continued to chip away at their intense workload, snapping pictures and sending reams of data earthward. What they imaged and reported would change our understanding of Mars overnight: the Martian Renaissance had begun.

    A treat for anyone interested in space exploration and the histo

    A treat for anyone interested in space exploration and the history of our growing relationship with Mars. Pyle’s conversational style makes his complex subject comprehensible to the layman even when discussing the intricate details of technology and Martian geography.

    Destination Mars begins with an account of the Viking 1 lander’s arrival on the Red Planet in 1976, then backtracks to discuss the history of mankind’s interaction with Mars from ancient times to the present. The book outlines each exploration, from Viking 1 to more recent endeavors, discussing key discoveries made in each venture. The encounters are narrated in an easy-to-read style, the individual probes and rovers seeming more like characters than simple pieces of machinery. This engaging style makes even the more esoteric subjects accessible.

    In addition to discussing the various missions, Pyle allows key figures involved in Mars exploration to speak for themselves, discussing various challenges of the projects they worked on. Pyle also discusses future missions such as the Mars Science Laboratory (MSL), nicknamed Curiosity, scheduled to land in August of 2012, and other possible missions.

    Overall, Destination Mars is a highly readable book packed with information. A must read for anyone interested in Mars in particular or space exploration in general.

    "Destination Mars" is an extremely well-written book,

    "Destination Mars" is an extremely well-written book, and the author's passion for the topic is evident throughout. Even for those not usually interested in space exploration, Pyle is able to present information about Mars research in a way that captures every reader's imagination. One of the strongest aspects of the book is the direct quotes from the researchers and scientists who directly worked on projects linked to Mars. It is exciting to hear the trials and triumphs of the space missions through the eyes of people who were there. Some of the scientific descriptions (like the names of the materials found on Mars) can be a little dense, but there are so many great anecdotes and interesting tidbits of information to outweigh the heavier material. It was particularly fascinating to learn how the researchers named different elements (often with tongue in cheek names) or what songs they played each time the rovers landed.

    I would recommend this book to anyone who is curious about the space program or even what's beyond our own planet.

    When I was a child, the exploration of space was a dream that wa

    When I was a child, the exploration of space was a dream that was slowly becoming a reality. I went from watching Lost in Space on TV to watching a rocket take off for the moon. And back then, a rocket launch was something to celebrate. TVs were brought into classrooms and the world stopped working and held their breath until moments after those words were heard – "We have liftoff."
    Since then, space travel has become somewhat common place in our society. The last few space shuttle flights left and came back with little fanfare. It's as if we've come to take space flight for granted. Like shooting a rocket into space is as easy as driving to the grocery store. We feel like that because the incredible men and women of our space program have made it look easy but there's nothing easy about it.

    Destination Mars is an extensive look at the history of the Mars exploration program. After only a few pages, you really start to understand the enormity of it all. Calculating flight speeds and landing sites, angles and temperatures and that's all just to get the craft from here to there. Once on Mars, these landers have to work miracles on their own, taking photos, testing the soil and the air. And if something goes wrong, it's not like you can bring it back, fix it and send it back for round two. The money and the man-hours invested into each mission is insane and one wrong move can mean the end of the mission.

    The best chapter in the book is called A Laugh in the Darkness: The Great Galactic Ghoul. This chapter discusses the two huge failures of 1998 and 1999. Now, it's not that I want to dwell on the negative, but I think we learn more from our mistakes than our successes and this chapter bears that out. The chapter eloquently points out that even though our space scientists and engineers are incredibly brilliant, they're also human and as humans they make mistakes. It's humbling, really, when you read about these lost efforts, which only served to make everyone work harder for next time.

    Destination Mars isn't an easy read. It's very detailed and over 300 pages long but the author does a great job of turning a complicated topic into a readable and entertaining book.

    This was my first time reading a book about the explorations of mars. Roy Pyle showed Mars as this unique planet where dreams can be formed but also revealed the scientist and engineers behind all that took place on these missions. I enjoyed the book, it was easy to read, well organized, a page turner. I would recommend this book to any one who has every dreamed of going to space, because this book takes you there.

    Rod Pyles book, "Destination Mars" offers a fascinatin

    Rod Pyles book, "Destination Mars" offers a fascinating history of Mars exploration and the scientist behind America's space satellite missions.

    Pyle details the triumphs, near misses and failures of Martian exploration in an entertaining and accessible way. He does an especially good job in describing the way that various satellites worked in layman’s terms without being condescending. He illustrates the manner in which information about Martian geology was obtained while explaining what that information meant to scientists in a clear manner. The book details the challenges and frustrations experienced by some of America's most brilliant minds as they struggled to unveil the mysteries of the red planet while battling naysayers from religious zealots to those who insisted that the space program wasn’t worth the money.

    "Destination Mars" offers a searing and insightful argument for keeping the space program alive.

    I thoroughly enjoyed this read. Ever since my junior high science teacher showed us how to find Mars in the night sky I’ve been fascinated with the red planet. I’ve watched all the cheesy science fiction movies about Mars and Martian coming to Earth and they are a lot of fun. Destination Mars is the flip side. It is the real science that has been used over the past forty years to show us humans what our neighboring planet is like. Maybe someday we’ll actually be living on Mars, like in the movies. If we do it will be because of the passionate work of thousands of people at JPL and Nasa. Their story is lovingly and told in this book. It is obvious that Pyle shares my love for Mars and has his own dream of setting foot on that red soil someday himself.

    One can easily get caught up in the excitement of exploring the red planet. Written in language understandable to the average reader without dumbing down the science, Pyle walks the fine line between hard science and accessibility. From the invention of the Gas Chromatograph to the earliest Viking landing in 1976 and the more recent Rover missions, Destination Mars relates in stunning detail the herculean effort it has taken to get a look at Mars. With numerous photos provided by the Jet Propulsion Laboratory and NASA you really get a feel for the Martian surface and experience the thrill of exploring. What other secrets does the red planet hold? Will exploration of our neighbor planet continue in the future? Only time will tell.

    I am a total geek for all things Mars! I heard about the book through word of a colleague at at work. I work around 'Tech Junkies' (I can call myself one too); and with the release this April I had to get my hands on a copy. I cover the 380 page book from cover to cover in a few shorts days. The historical narrative is well written and expertly detailed. The scientific research is thorough and detailed, which adds to my keen interest. I sincerely recommend this book for those from any path of life!

    I bought this book after reading enthusiastic reviews on Publisher's Weekly and in the journal "Nature," as I respect both publications. "Destination Mars" is a fact-based book about the human exploration of Mars, yet in the tradition of Simon Winchester and others, reads like an adventure novel. Beginning with a you-are-there accounting of the landing of Viking 1 in 1976 (one of my personal favorite moments from childhood- yes I am a Mars enthusiast), the author gives us a brief introduction to Mars as a physical entity, then goes back in time to review how humanity's understanding of the planet has evolved. Finally, as the author puts it, in 1965, the Victorian-era idea of a "Martian Empire was smashed" when NASA's Mariner 4 flew past the planet, revealing a dry, dead place. The rest of the book moves through the missions of JPL and others as robots were sent off to explore the red planet. Finally, the book discusses Earth-based efforts to research the Martian environs via terrestrial analogues (Antarctica, the Atacama desert, etc), then sketches out future exploration scenarios.

    The overall tone is one of enthusiasm and reverence for the robotic drones such as the Mariners, Viking, the Mars rovers and upcoming Mars Science Lab. While there is much discussion of the discoveries made there and the science involved, I never found my attention wandering- this is a book for the layman.

    I heartily recommend "Destination Mars" as an enjoyable and educational read.
