For nearly fifty years, a wide range of missiles and rockets has propelled U.S. satellites and spacecraft into the sky. J. D. Hunley's two-volume work traces the evolution of this technology, from Robert Goddard's research in the 1920s through the development of the Titan missiles and from Vanguard launch vehicles in the 1950s to the space shuttle in the 1980s. With the first book devoted primarily to military hardware and the second to launch vehicle hardware, Hunley offers a sweeping overview of these impressive engineering innovations as well as insights into the dynamic personalities responsible for them. Together, the two volumes offer a unique, invaluable history of rocketry that should appeal to a wide range of scholars and space buffs.
