Moon Lander

Chief engineer Thomas J. Kelly gives a firsthand account of designing, building, testing, and flying the Apollo lunar module. It was, he writes, “an aerospace engineer’s dream job of the century.” Kelly’s account begins with the imaginative process of sketching solutions to a host of technical challenges with an emphasis on safety, reliability, and maintainability. He catalogs numerous test failures, including propulsion-system leaks, ascent-engine instability, stress corrosion of the aluminum alloy parts, and battery problems, as well as their fixes under the ever-present constraints of budget and schedule. He also recaptures the exhilaration of hearing Apollo 11’s Neil Armstrong report that “The Eagle has landed,” and the pride of having inadvertently provided a vital “lifeboat” for the crew of the disabled Apollo 13.“A highly personalized story . . . of the Apollo Lunar Module, built at Grumman by the author and his team.”—Choice

“It’s surprising that the man most responsible for the spindly Apollo lunar landers, Tom Kelly, hasn’t told his story years before. Lucid and engaging, he tells how his team at Grumman in Bethpage, Long Island, went from paper studies to delivering hardware that would help change history. Beyond historical interest, the book has lessons for anyone involved in a large project at the cutting edge of technology.”—IEEE Spectrum

 “. . . Written in an approachable style, and if you have even a passing interest in space exploration it will grip your interest. It constitutes an important primary source for the history of human exploration . . . This book is a flat-out good read.”—Meteoritics and Planetary Science

The recipient of a Grumman Engineering Scholarship upon graduating from high school, Thomas J. Kelly worked for the company for more than forty years, retiring in 1992. Now an aerospace and computer consultant, he lives in Cutchogue, New York.

“It was the first space launch [Apollo 5] we had seen firsthand, and it did not disappoint in spectacle and beauty. First we beheld the brilliant orange flame of the Saturn 1B, then the agonizing wait until the hold-down clamps were released and the rocket began its slow climb upward alongside the launch tower finally clearing it. Then came the heavy, deep-throated roar of the mighty engines, simultaneously pressing down from the sky and upward, like an earthquake, from below the ground. Set majestically against the rose, purple, and deep blue of the dusky sky, the blazing torch of the rocket lit up the approaching night for miles around. It was a thrilling sight but also reminded me of the inherent risk of our whole enterprise. So much raw power unleashed in such a short time!”—from Chapter 13
