On March 22, 1952, the American weekly feature magazine Collier's hit the newsstands. Among its usual mixture of advertisements and articles was the first of a series of features that would run for the next two years. These seemed like the wildest science fiction at the time, but would become established fact within a surprisingly few years.

Later compiled into and expanded by three coffee table books – Across the Space Frontier (1952), Conquest of the Moon (1953), and The Exploration of Mars (1956) – the series was the brainchild of Wernher von Braun, one of the great rocket pioneers of the 20th century. He was the man behind Germany's V2 rocket, and architect of the Saturn V booster that would send the first men to the Moon on the Apollo missions.

With the help of his friend, popular science author and fellow Germany expatriate Willy Ley, von Braun arranged an introduction to Cornelius Ryan, the editor of Collier's. He sold him on the idea of a major feature series and they then recruited Ley, the astronomer Fred L. Whipple, space medicine expert Hans Haber, and American law and international diplomacy professor Oscar Schachter to write articles with von Braun that brought his vision of the conquest of space to life.

Where Apollo put two astronauts on the Moon in a single lander, von Braun envisioned an armada of three giant moonships, each taller than the Statue of Liberty and containing a total crew of 50. Two of the ships would have been reusable, while the third would be dismantled to provide the raw material for the first moonbase complete with laboratories and electric tractors for long-distance recon missions.

These monster ships would have been built at an equally gigantic space station orbiting 1,075 mi (1,730 km) above the Earth. It would have a diameter of 250 ft (76 m), be powered by solar panels that boiled mercury for turbines, and hold a crew of 80 in comfort as the giant wheel rotated to provide one-third Earth gravity. This US$4-billion station, to be completed by 1967, would be built and serviced by a fleet of ferry rockets with reusable shuttles bringing cargo and personnel aloft.

And once the Moon was conquered by 1977, von Braun already had Mars in his sights with another fleet of manned ships to explore the Red Planet. Not only did this series provide material for books, but it was the basis for three color television documentaries on space travel for Walt Disney in 1955 and 1957 that featured von Braun and many of the other authors.

The von Braun archive up for bidding by RR Auction consists of 26 items related to four of the articles in Collier's: "Crossing the Last Frontier," "Man on the Moon: The Journey," "Man on the Moon: The Exploration," and "Baby Space Station," as well as copies of the four magazines that carried them.

In addition to the sketches that von Braun provided for the artists, the archive also contains cover letters, detailed orbital calculations and graphs, and various other notes that outline his vision for the space station, the shuttle, the moonship, moon transport, and a miniature satellite that would act as a pathfinder for all the other missions.

Along with the von Braun archive, the Space and Aviation Auction also features an American flag flown on the Apollo 10 mission, Buzz Aldrin's star chart flown on Apollo 11, a Lunar Rover map used by Gene Cernan on Apollo 17, a urine collection system for an Apollo spacesuit, a spacesuit glove worn by Neil Armstrong, and a Space Shuttle external nose cone assembly.
