Digital Apollo: Human and Machine in Spaceflight (Mit Press) Paperback – Illustrated, September 30, 2011
Purchase options and add-ons
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.

- Reviewed in the United States on February 5, 2011You might think a book entitled "Digital Apollo" would be about the development, programming and operation of the digital computers in the Apollo Command (CM) and Lunar (LM) Modules. You would be partially right. About half of Dr. David Mindell's superb volume covers those subjects, very readably and in great detail. But the book's scope is far broader than that. It is really nothing less than a comprehensive examination of the relationships between humans and machines from the earliest days of aviation, through the X-15, Mercury, Gemini, Apollo and Space Shuttle eras, and into the future of spaceflight.
It's a fascinating story that has not, to my knowledge, previously been told in any depth. The evolution of the Apollo computer hardware and software occurred in parallel with the evolution of the attitudes of steely eyed NASA astronauts, who fought hard to avoid relinquishing any control to machines. All the early astronauts were test pilots--their hard-won experiences with primitive vacuum-tube systems in aircraft had convinced them that "electronics always fail." Thus they opposed NASA's decision, mandated by the complexity of lunar missions, to depend largely on new-fangled transistorized digital computers to help them fly the Apollo spacecraft. At one time, in those days before "fly-by-wire" control systems, some Apollo astronauts wanted actual cables connecting a conventional aircraft-type stick with the CM's attitude control rocket motors. That didn't happen. They feared that computer failures would jeopardize their missions and perhaps cost them their lives. That also didn't happen. To find out what DID happen, there's no better source than "Digital Apollo."
Dr. Mindell says his book "...tells the story of the relationship between human and machine in the Apollo project and how that relationship shaped the experience and the technology of flying to the moon. It is a story of human pilots, of automated systems, and of the two working together to achieve the ultimate in flight. It is also a story of public imagery, professional identities and social relationships among engineers, pilots, flight controllers and many others, each with their own visions of spaceflight." That's a good summary, but I'd like to add to it. First, words like "social relationships" and "working together" and "visions" should not deter technophiles from reading "Digital Apollo." Those subjects are all in there, but much of the book is at the down-and-dirty technical level of bits and bytes and magnetic core memories and DSKYs and other esoterica. Dr. Mindell superbly integrates the human and computer stories in a way that almost anyone should find interesting. Second, "Digital Apollo" is one of the best-written spaceflight books I've read in years. Its tone is brisk and conversational, but the information it contains is deep, broad and very well-explained. You don't have to be a space cadet to enjoy it. It is also exceptionally accurate. I came across only a few minor errors in the parts of the story that I know, such as calling a metal alloy used in the X-15 "Iconel-X" rather than "Inconel-X" (the alloy and the name came from the International Nickel Company, hence "Inco").
"Digital Apollo" fills a niche in the history of technology and spaceflight in a most outstanding way. It reminds me a little of Tracy Kidder's "The Soul of A New Machine," and that is high praise indeed. Even if you think you know Apollo, you should read it. You're sure to learn a lot, and be entertained in the process. I recommend it most highly.
- Reviewed in the United States on August 31, 2009In "Digital Apollo" David Mindell has created a thoughtful and readable account of the design of the Apollo Guidance Computer (AGC), the software that allowed it to succeed, the history of its use, and the bigger picture issues of human factors and automation interface issues in complex systems in general. While I differ with him on some of his perspectives (I am a pilot, and tend to side with the "man in the loop" opinions held by the astronauts, most eloquently voiced by Neil Armstrong and Dave Scott), I found the entire book engrossing and his approach to complex human factors, ergonomic, and automation issues to be extraordinarily useful, especially to professionals in the field.
The book traces the history of the AGC, discusses its growth and capabilities, and its real world use. I was especially pleased with chapters nine and ten which dealt in detail with each of the six landings, differences between the landings, and differing attitudes held by the various astronauts about the computer and its functionality. I was pleased with the detailed coverage that Apollo 12 got, and the explanations of the increasing complexity of the "J missions" which took heavier LMs into much more difficult terrain much more steeply. Mindell gives the best explanation I have yet read (p. 205) of the use of the Landing Point Designator (LPD), and computer incorporation of landing radar returns and resulting Delta H data into final altitude solutions for the crew. As an aside, don't stop reading until the very end: the very last page (p. 361) contans an excellent explanation of the extremely well rendered cover illustration depicting the view from Armstrong's window at about 520 feet above the lurain.
The book is, like any endeavor of this scope, not perfect, with an occasional error or typo: most seem to be due to spell check artifacts not recognizing unusual word use. (The most obvious example is the discussion of the Apollo 1201 and 1202 program alarms on p. 222 which he refers to as "executive overload" instead of "executive overflow" alarms, even though he subsequently used the word overflow correctly in reference to these same events. Amusingly enough, the quote about the alarms from Norman Mailer doesn't really make sense if you read the word as "overload.") This is, of course, nitpicking, and I absolutely don't intend to take away from a brilliant career accomplishment.
The ideal reader for this book will care passionately about manned space flight, and will find Apollo especially worthy of in-depth study. The book does not require any previous knowledge of spaceflight, human factors, computer interface issues, or aviation, but will be slower going for someone with no background in those areas (though still worthwhile). It is not a technical book in the sense that only engineers, programmers, astronauts, or pilots can glean useful information from it, but it does touch on a variety of complex subjects. Fortunately Mindell is more than up to the task and makes learning about this fascinating subject highly rewarding. I recommend this book very highly.
- Reviewed in the United States on January 5, 2013This is wonderful book on the technological side of Apollo. I have not found another that even comes close. I would have loved to give it 5 stars, but many of the photos and illustrations were missing. Also most of the ones that were present were very small and of low resolution. I could forgive that for they would be all that an early Kindle could display, but on a Kindle Fire they simply are too small.
Again a great book, just one with minor flaws.

Eduardo Henrique dos SantosReviewed in Brazil on November 10, 2021
5.0 out of 5 stars Excelente leitura
Eu curti demais o livro. Ele realmente traz uma visão diferente do que se imagina pelo título. Apesar de se procurar elucidar a grande oportunidade e avanços provocados pela tecnologia digital, ora engatinhando, é possível ter uma noção boa do que ocorreu nos instantes antes, durante e após a definição do presidente Kennedy de levar o homem à lua.
Entende-se o quão a tecnologia evoluiu desde os irmãos Wright até a ida do do homem à lua. Tudo isso em apenas duas gerações.
Além disso, o livro aborda os conflitos entre a decisão de máquinas autônomas fazendo tudo ou a possibilidade de o homem ter influência sobre essas máquinas, dando-se ou não o devido valor aos pilotos de caça e astronautas. Isso desde os projetos Mercury e Gemini, e que tiveram influência fundamental nas decisões de Engenharia de sistemas que nortearam todo o programa Apollo.
Mostra um pouco do desafio em se desenvolver algo inédito e desacreditado por muitos, chamado computador digital, instalado sem redundância em uma nave espacial, preparada para funcionar por 8 dias consecutivos, com memória limitada e de extrama dificuldade de programação e teste.
Além disso, o livro aborda o que ocorreu em todas as missões Apollo. Há uma descrição detalhada da entrada em órbita lunar e pouso do Eagle sob o comando do Armstrong, além das dificuldades e o quão ele foi fundamental para que o pouso realmente ocorresse.
O livro, mais do que agradável, tem muita história viva, pessoas fundamentais, nomes que só tinha ouvido falar quando nos estudos da matéria de Controle na faculdade e a importância dessas pessoas em todas as façanhas desse feito de engenharia.
Só quem trabalha com tecnologia sabe as dificuldades de refazer esse feito hoje em dia. O pessoal fez isso há 52 anos. So... Respect!
Recomendo a todos aqueles entusiastas de tecnologia, espaço, aeronáutica, engenharia de sistemas, navegação e sobretudo para quem gosta de ler sobre boas histórias.

5.0 out of 5 stars Very good book, exactly what I was looking for
This book covers both technical aspects and historical aspects of spaceflight dynamics. Topics such as the X15, Mercury, Gemini and Apollo are covered in relative depth.
I particularly enjoyed this book (you know, I'm something of a space fan myself...) because it sheds light on things that I'd never heard about before and that are usually sidelined as seen less interesting than the astronaut's experience (im not saying that it's less interesting).
Definitely a must read for space exploration enthusiasts.

5.0 out of 5 stars Good book that covers all aspects of the Apollo missions
I am very interested in the history of the apollo missions and the computer systems that enabled them to land on the moon. This book is in two halfs, the first is more focused on the astronauts and the pre apollo planes and training. The second half focuses on the computing and technology usef.

5.0 out of 5 stars Indispensable
Lo he disfrutado de principio a fin aunque, como ingeniero que se dedica a desarrollar sistemas de control, me hubiera gustado un poco más de "chicha" técnica.
Es llamativo ver cómo algo que al principio se pensó usar para poco más que sustituir a los integradores analógicos de los acelerómetros del sistema inercial, pasó a ser una herramienta que, de no haber existido, habría hecho prácticamente inviable el proyecto Apolo.
El sistema de almacenamiento del código en memoria de sólo lectura a base de "trenzas" de hilos plagadas de ferritas resulta enternecedor visto desde nuestra perspectiva.
Decisiones como forzar que cada rutina guardase continuamente en memoria no volátil su estado de manera que pudiese continuar en el punto en el que estaba en caso de rearranque del procesador por intervención del watch-dog (algo que por lo visto sucedía bastantes veces), con lo que estos rapidísimos (por no haber sistema operativo) rearranques apenas entorpecían los procesos de control, pueden resultar llamativas hoy día.
En fin, multitud de detalles interesantes para el lector con formación técnica, pero también para el lego en la materia.
