"For simplicity the contents of this Pocket Book are divided into the five most widely used categories -- manned, interplanetary, scientific and applications, plus launch vehicles. The section on manned spacecraft includes all types of craft ever flown because all are so familiar that even the earliest are still in the public domain. Likewise, a certain historical element exists among the interplanetary spacecraft selection by virtue of the distinctiveness of each step in Man's reaching out from his planet. Among the launch vehicles, too, are a few defunct but celebrated programmes. Soviet launchers are designated according to Charles S. Sheldon's alphabetical/numerical system plus available Russian names. New Nasa-devised designators are also quoted in some cases." --Introduction, page [8].
