was the title of a series of 1950s magazine articles in Collier's detailing Wernher von Braun's plans for human spaceflight.
Edited by Cornelius Ryan, the individual articles were authored by such space notables of the time as Willy Ley, Fred Lawrence Whipple, Dr. Joseph Kaplan, Dr. Heinz Haber, and von Braun.
The magazine articles showed earth orbit missions and lunar surface exploration, to be undertaken by large crews in the 1960/70s timeframe.
Several concept vehicles were proposed and described in detail, such as a ferry rocket,[1] a Space Station,[2] and a Lunar Lander.
Examples of some of the ships they modeled are in the World of Collier's add-ons to the Orbiter space flight simulator.
