Other editions of book Expedition Mars

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)
