On October 4, 1957, the Soviet Union launched Sputnik I, and the space race was born. Desperate to beat the Russians into space, NASA put together a crew of the nation's most daring test pilots: the seven men who were to lead America to the moon. The first into space was Alan Shepard; the last was Deke Slayton, whose irregular heartbeat kept him grounded until 1975. They spent the 1960s at the forefront of NASA's effort to conquer space, and Moon Shot is their inside account of what many call the 20th century's greatest feat - landing humans on another world.

On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals including Allan McDonald. The fiery destruction of Challenger on live television moments after launch remains an indelible image in the nation's collective memory. In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center.

The history of computing could be told as the story of hardware and software or the story of the Internet or the story of "smart" handheld devices, with subplots involving IBM, Microsoft, Apple, Facebook, and Twitter. In this concise and accessible account of the invention and development of digital technology, computer historian Paul Ceruzzi offers a broader and more useful perspective. He identifies four major threads that run throughout all of computing's technological development.

After the Apollo program put 12 men on the moon and safely brought them home, anything seemed possible. In this spirit, the team at NASA set about developing the space shuttle, arguably the most complex piece of machinery ever created.

Renowned space historian John Logsdon traces the greatest moments in human spaceflight by weaving together essential, fascinating documents from NASA's history with his expert narrative guidance. Beginning with rocket genius Wernher von Braun's vision for voyaging to Mars and closing with Elon Musk's contemporary plan to get there, this volume traces major events like the founding of NASA, the first American astronauts in space, the Apollo moon landings, the Challenger disaster, the daring Hubble Telescope repairs, and more.

As NASA prepared for the launch of Apollo 11 in July 1969, many African American leaders protested the billions of dollars used to fund "space joyrides" rather than help tackle poverty, inequality, and discrimination at home. This volume examines such tensions as well as the ways in which NASA's goal of space exploration aligned with the cause of racial equality. It provides new insights into the complex relationship between the space program and the civil rights movement in the Jim Crow South and abroad.

In Code Work, Hector Beltrán examines Mexican and Latinx coders' personal strategies of self-making as they navigate a transnational economy of tech work. Beltrán shows how these hackers apply concepts from the code worlds to their lived experiences, deploying batches, loose coupling, iterative processing (looping), hacking, prototyping, and full-stack development in their daily social interactions-at home, in the workplace, on the dating scene, and in their understanding of the economy, culture, and geopolitics.

Homesteading Space is more than a story of technological and scientific success; it is also an absorbing, sometimes humorous, often inspiring account of the determined, hardworking individuals who shepherded the program through a near-disastrous launch, a heroic rescue, an exhausting study of Comet Kohoutek, and the lab's descent into the Indian Ocean. Featuring the unpublished in-flight diary of astronaut Alan Bean, it is replete with the personal recollections and experiences of the Skylab crew and those who worked with them in training, during the mission, and the return.

Humanity's first reusable spacecraft and the most complex machine ever built, NASA's space shuttle debuted with great promise and as a dependable source of wonder and national pride. But with the Challenger catastrophe in 1986, the whole space shuttle program came into question, as did NASA itself, so long an institution that was seemingly above reproach. Wheels Stop tells the stirring story of how, after the Challenger disaster, the space shuttle not only recovered but went on to perform its greatest missions.

Driven by eyewitness accounts and combining urban history with a life-and-death drama and a technological detective story, Floodpath grippingly reanimates the reality behind LA noir fictions like the classic film Chinatown. In an era of climate change, increasing demand on water resources, and a neglected American infrastructure, the tragedy of the St. Francis Dam has never been more relevant.

The intercontinental ballistic missile (ICBM), designed to quickly deliver thermonuclear weapons to distant targets, was the central weapons system of the Cold War. ICBMs also carried the first astronauts and cosmonauts into orbit. More than a generation later, we are still living with the political, technological, and scientific effects of the space race, while nuclear-armed ICBMs remain on alert and in the headlines around the world. Christopher Gainor explores the US Air Force's decision, in March 1954, to build the Atlas, America's first ICBM.

At the onset of the American Revolution, the British expected to quell the rebellion quickly with a show of overwhelming force. In an experiment in asymmetric warfare, David Bushnell created the first submarine vessel designed specifically “for the destruction of vessels of war”. In Turtle, the authors provide new insight into Bushnell’s “engine of devastation”, tracing the history of undersea warfare before Bushnell and the origin of the many innovations Bushnell understood would be necessary for conducting a covert submarine attack.

Throughout the 1960s and 1970s, a diverse group of teachers and students working together on academic computing systems conducted many of the activities we now recognize as personal and social computing. Joy Rankin draws on detailed records to explore how users exchanged messages, programmed music and poems, fostered communities, and developed computer games like The Oregon Trail. These unsung pioneers helped shape our digital world, just as much as the inventors, garage hobbyists, and eccentric billionaires of Palo Alto.

Humans have been farming for thousands of years, and yet agriculture has undergone more fundamental changes in the past 80 years than in the previous several centuries. In 1900, 30 million American farmers tilled the soil or tended livestock; today there are fewer than 4.5 million farmers who feed a population four times larger than it was at the beginning of the century.

In two southern Illinois towns only forty miles apart, explosions killed 111 men at the Centralia No. 5 mine in 1947 and 119 men at the New Orient No. 2 mine in West Frankfort in 1951. Robert E. Hartley and David Kenney explain the causes of the accidents, identify who was to blame, and detail the emotional impact the disasters had on the survivors, their families, and their communities.

Activists, pundits, politicians, and the press frequently proclaim today's digitally mediated racial justice activism the new civil rights movement. As Charlton D. McIlwain shows in this book, the story of racial justice movement organizing online is much longer and varied than most people know. Beginning with the simultaneous rise of civil rights and computer revolutions in the 1960s, McIlwain, for the first time, chronicles the long relationship between African Americans, computing technology, and the Internet.

The history of the American gun is intricately entwined with the history of America itself, and the potential future developments in gun technology could change the world. However, the radical anti-gun lobby stands between innovation and the American people. Bestselling author Frank Miniter describes amazing breakthroughs waiting to happen in gun technology - and how gun grabbers threaten to stop progress in its tracks.
