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 launch vehicles in the 1960s to the refinement of 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.Thus it was not until early 1981 that the space shuttle main engine fully qualified for flight. ... from 65 to 109 percent of their rated power level, although there had been so many problems demonstrating the 109 percent level in testing that it was not available on a routine basis until 2001. ... Saturn engine, which had a specific impulse of somewhat more than 290 lbf-sec/lbm at sea level and 420 at altitude.
