This authoritative, illustrated history chronicles the Vanguard project, which placed one of the United States' earliest successful man-made satellites into Earth orbit. In addition to analysis of the program's scientific and technical challenges, it surveys the influence of the launchings of the first Russian Sputniks and Vanguard's impact on subsequent space missions.
