This website is an update to the printed version of this NASA publication 2000-4029, Apollo By The Numbers: A Statistical Reference, published in the spring of 2001.


The printed version was produced four years after the research and writing had been completed. During that period, essentially no editing was done to the original manuscript. Following publication, the author received many compliments and comments, including suggestions for additional and updated information, corrections, format changes and recommendations for editing some text for clarity. All these suggestions have been incorporated into this website.


Even so, Apollo By The Numbers remains a living document. The author welcomes any suggestions for improving the information offered by this revised version of the published book.
