On July 20, 1969, the whole world gathered around their flickering television sets and watched in awe as astronaut Neil Armstrong who, if not for someone secretly slipping his very late application to the astronaut program into the pile wouldn’t have even been there (more on this in the Bonus Facts later), climbed down the leg of a strange, spidery vehicle, stepped onto the surface of the moon, and spoke the immortal words: “That’s one small step for [a] man, one giant leap for mankind.” …Followed by the much less memorable second words, “I can – I can pick it up loosely with my toe. It does adhere in fine layers like powdered charcoal to the sole and sides of my boots. I only go in a small fraction of an inch, maybe an eighth of an inch, but I can see the footprints of my boots and the treads in the fine, sandy particles.”

But for the first time in history, a human being had set foot on another world. The historic flight of Apollo 11 was the culmination of a massive eight-year effort to realize President John F. Kennedy’s goal of landing a man on the moon and returning him safely to the earth by the end of the decade. But the road from the earth to the moon was far from a smooth one, beset by numerous hurdles and setbacks. For example, the deaths of the Apollo 1 crew in a launch pad fire on January 27, 1967 prompted a complete redesign of the Apollo spacecraft, while ongoing problems with the Saturn V rocket’s massive F-1 rocket engines nearly resulted in the cancellation of the entire Apollo programme. But perhaps the greatest challenge of all was deciding how to land on the moon in the first place. Solving this seemingly trivial question proved far more difficult than expected, requiring years of careful study and the heroic persistence of an obscure but determined engineer. This is the story of how we learned to land on the moon only a little over a half century after humans were still hitching up covered wagons to go places.
