Kennedy went before Congress to call for the United States to land humans on the Moon and return them safely to Earth “before this decade is out.” The Space Race was on. Inasmuch as NASA had yet to send a Mercury into Earth orbit, Kennedy’s challenge was a formidable one. Neither the spacecraft nor launch vehicles and facilities for a lunar landing existed, nor did operational techniques for conducting it.

By 1970, public interest in lunar ex- ploration had waned, and a new Ad- ministration committed to a space- based defense system and to reducing federal spending was in office. Budget cuts forced NASA to sacrifice current projects in order to support future ones. One Apollo mission was can- celed in January, 1970; two more were dropped the following September.

Many books have been written about the Apollo Program, most of them about Apollo 11. Few have given us an inside look at the delicate melding of man and machine. Contributing to this complete history of America’s piloted space programs, Collins devotes a large portion to Apollo. He sets the record straight on some of the mis- conceptions of astronauts and .

Excellent Fiftieth Anniversary collector’s item and historical review. Harland, David M. Exploring the Moon: The Apollo Expeditions. Chichester, England: Springer- Praxis, 1999. Exploring the Moon focuses on the exploration carried out by the Apollo astronauts while on the lunar surface, not on the technology of getting there. It is a story of the great adventure of exploring the Moon, and combines the words of the astronauts themselves with the photographs they took. Exploring the Moon is a minute-by-minute account of what the astronauts did, said, and felt, enhanced by their sub- sequent reflections. Kelly, Thomas J. Moon Lander: How We Developed the . Washington, D.C.: Smithso- nian Books, 2001. Chief 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 anticipation of the first unmanned Lunar Module flight with Apollo 5 in 1968, the -ex hilaration of hearing Apollo 11’s Neil A. 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. USA in Space Apollo Program 33

Here is the Apollo Program lunar-landing story as told by the twelve men who walked on the Moon. Learn what it was like to be a part of the Apollo Program and take a stroll in the lunar sunlight. The authors sat down with each of the astronauts and discussed both the flights and their lives before the mission and since. Some of the tales of the behind-the-scenes activities are priceless. Only a few of the questions seem out of place, but it should be left to the reader to decide which, if any, are. The book is illustrated with color paintings by astronaut-artist Alan L. Bean.
