On May 24, 1869 a one-armed Civil War veteran, John Wesley Powell, and a ragtag band of nine mountain men embarked on the last great quest in the American West. The Grand Canyon, not explored before, was as mysterious as Atlantis - and as perilous. The 10 men set out from Green River Station, Wyoming Territory, down the Colorado in four wooden rowboats. Ninety-nine days later, six half-starved wretches came ashore near Callville, Arizona.

In 1803, President Thomas Jefferson selected his personal secretary, Captain Meriwether Lewis, to lead a voyage up the Missouri River, across the forbidding Rockies, and - by way of the Snake and the Columbia rivers - down to the Pacific Ocean. Lewis and his partner, Captain William Clark, endured incredible hardships and witnessed astounding sights. With great perseverance, they worked their way into an unexplored West. When they returned two years later, they had long since been given up for dead.

The Viking Age - from 750 to 1050 saw an unprecedented expansion of the Scandinavian peoples into the wider world. As traders and raiders, explorers and colonists, they ranged from eastern North America to the Asian steppe. But for centuries, the Vikings have been seen through the eyes of others, distorted to suit the tastes of medieval clerics and Elizabethan playwrights, Victorian imperialists, Nazis, and more. None of these appropriations capture the real Vikings, or the richness and sophistication of their culture.

In 1528, a mission set out from Spain to colonize Florida. But the expedition went horribly wrong: Delayed by a hurricane, knocked off course by a colossal error of navigation, and ultimately doomed by a disastrous decision to separate the men from their ships, the mission quickly became a desperate journey of survival. Of the 300 men who had embarked on the journey, only four survived - three Spaniards and an African slave.

The “mountain men” were the hunters and trappers who fiercely strode the Rocky Mountains in the early to mid-1800s. They braved the elements in search of the skins of beavers and other wild animals, to sell or barter for goods. The lifestyle of the mountain men could be harsh, existing as they did among animals, and spending most of their days and nights living and camping out in the great unexplored wilds of the Rockies.

They came on foot and by horseback, in wagons and on rafts, singly and by the score, restless, adventurous, enterprising, relentless, seeking a foothold on the future. European immigrants and American colonists, settlers and speculators, soldiers and missionaries, fugitives from justice and from despair-pioneers all, in the great and inexorable westward expansion defined at its heart by the majestic flow of the Ohio River. This is their story, a chronicle of monumental dimension, of resounding drama and impact set during a pivotal era in our history: the birth and growth of a nation.

Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves. Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes "backwards" sometimes; how to turn the tide in the fight against AIDS.

In February 1959, a group of nine experienced hikers in the Russian Ural Mountains died mysteriously on an elevation known as Dead Mountain. Eerie aspects of the incident—unexplained violent injuries, signs that they cut open and fled the tent without proper clothing or shoes, a strange final photograph taken by one of the hikers, and elevated levels of radiation found on some of their clothes—have led to decades of speculation over what really happened.

Apollo is the behind-the-scenes story of an epic achievement. Based on exhaustive research that included many exclusive interviews, Apollo tells how America went from a standing start to a landing on the moon at a speed that now seems impossible. It describes the unprecedented engineering challenges that had to be overcome to create the mammoth Saturn V and the facilities to launch it.

More than 200 million years ago, geological forces split apart the continents. Isolated from each other, the two halves of the world developed radically different suites of plants and animals. When Christopher Columbus set foot in the Americas, he ended that separation at a stroke. Driven by the economic goal of establishing trade with China, he accidentally set off an ecological convulsion as European vessels carried thousands of species to new homes across the oceans.

Written with all the color and drama of the best fiction, Apollo 13 (previously published as Lost Moon) tells the full story of the moon shot that almost ended in catastrophe.

For millennia the location of the Nile River’s headwaters was shrouded in mystery. In the 19th century, there was a frenzy of interest in ancient Egypt. At the same time, European powers sent off waves of explorations intended to map the unknown corners of the globe—and extend their colonial empires.

In the summer of 1913, the wooden-hulled brigantine Karluk departed Canada for the Arctic Ocean. At the helm was Captain Bob Bartlett, considered the world’s greatest living ice navigator. The expedition’s visionary leader was a flamboyant impresario named Vilhjalmur Stefansson hungry for fame. Just six weeks after the Karluk departed, giant ice floes closed in around her. As the ship became icebound, Stefansson disembarked with five companions and struck out on what he claimed was a 10-day caribou hunting trip. Most on board would never see him again.

Breaking All The Rules: The Inside Story of the New Race traces the origins of a second Space Race that began at the end of the original 1960s US-Soviet space race and eventually led to SpaceX and the explosive growth in commercial space being seen today. The story covers how this revolution began with a band of misfit engineers and scientists and the inside story of how this was eventually ignited with the money and vision of billionaires such as Elon Musk, Jeff Bezos, and Richard Branson.

In August 1897, the young Belgian commandant Adrien de Gerlache set sail for a three-year expedition aboard the good ship Belgica with dreams of glory.
