From the reviews:
"...I enjoyed the historical descriptions of the contributions of the early rocket pioneers Konstantin Tsiolkovsky, Robert Goddard, and Wernher von Braun, as well as the American and Russian manned programs...The book is aimed at the science-literate public, although the material varies in level of detail." (George D. Nelson, PHYSICS TODAY, June 2005)
