As Apollo 11's Lunar Module descended toward the moon under automatic control, a program alarm in the guidance computer's software nearly caused a mission abort. Neil Armstrong responded by switching off the automatic mode and taking direct control. He stopped monitoring the computer and began flying the spacecraft, relying on skill to land it and earning praise for a triumph of human over machine. In Digital Apollo, engineer-historian David Mindell takes this famous moment as a starting point for an exploration of the relationship between humans and computers in the Apollo program. In each of the six Apollo landings, the astronaut in command seized control from the computer and landed with his hand on the stick. Mindell recounts the story of astronauts' desire to control their spacecraft in parallel with the history of the Apollo Guidance Computer. From the early days of aviation through the birth of spaceflight, test pilots and astronauts sought to be more than "spam in a can" despite the automatic controls, digital computers, and software developed by engineers. Digital Apollo examines the design and execution of each of the six Apollo moon landings, drawing on transcripts and data telemetry from the flights, astronaut interviews, and NASA's extensive archives. Mindell's exploration of how human pilots and automated systems worked together to achieve the ultimate in flight--a lunar landing--traces and reframes the debate over the future of humans and automation in space. The results have implications for any venture in which human roles seem threatened by automated systems, whether it is the work at our desktops or the future of exploration.David A. Mindell is Dibner Professor of the History of Engineering and Manufacturing, Professor of Engineering Systems, and Director of the Program in Science, Technology, and Society at MIT. He is the author of Between Human and Machine: Feedback, Control, and Computing before Cybernetics and War, Technology, and Experience aboard the USS Monitor.

This textbook covers the range of psychological and interpersonal issues that can affect astronauts living and working in space. It deals with the three major risk areas cited by NASA’s Behavioral Health and Performance Element: Behavioral Medicine, Team Risk, and Sleep Risk. Based on the author’s more than 50 years of experience in space-related activities writing, conducting research, and teaching undergraduate and graduate courses, the book follows a comprehensive range of topics that include: cognitive effects; psychiatric issues; cultural influences; salutogenic and positive aspects of space travel; autonomy and delayed communication; current plans to return to the Moon and Mars; analysis of study environments such as the polar regions, submersible habitats, and space simulation facilities; and more. It draws on research, literature, and case studies from the 1950s onward, showing readers in a natural and accessible way how the field has progressed over time. The book contains ample end-of-chapter summaries and exercises as well as a complete glossary of key terms. As such, it will serve students taking courses in aerospace psychology, psychiatry, sociology, human factors, medicine, and related social sciences, in addition to space industry professionals and others interested in the complexities of people living and working in space.

The N1 was the booster rocket for the Soviet manned moon program and was thus the direct counterpart of the Saturn V, the rocket that took American astronauts to the moon in 1969. Standing 345 feet tall, the N1 was the largest rocket ever built by the Soviets and was roughly the same height and weight as the Saturn. Though initially ahead of the US in the space race, the Soviets lagged behind as the pace for being first on the moon accelerated. Massive technical and personnel difficulties, plus spectacular failures, repeatedly delayed the N1 program. After the successful American landings on the moon, it was finally canceled without the N1 ever achieving orbit. The complete history of this rarely known Soviet program is presented here, starting in 1959, along with detailed technical descriptions of the N1's design and development. A full discussion of its attempted launches, disasters, and ultimate cancellation in 1974 completes this definitive history.
