Saturn Illustrated Chronology, MHR-5

David S. Akens’ illustrated chronology of the Saturn rocket program’s first eleven years, April 1957 through April 1968, published by the Historical Office at Marshall Space Flight Center. This copy is the fifth and final edition (1971), superseding four earlier editions (1963, 1965, 1967, 1969) as the chronology’s coverage grew year by year; NASA’s own history office describes it as the most complete version, adding a glossary, a 528-item bibliography, and an index not found in the earlier printings.
