context_page_description: Wernher Magnus Maximilian Freiherr von Braun was a German–born American aerospace engineer and space architect. He was the leading figure in the development of rocket technology in Nazi Germany and a pioneer of rocket and space technology in the United States.
  While in his twenties and early thirties, von Braun worked in Nazi Germany's rocket development program. He helped design and develop the V-2 rocket at Peenemünde during World War II. Following the war he was secretly moved to the United States, along with about 1,600 other German scientists, engineers, and technicians, as part of Operation Paperclip. He worked for the United States Army on an intermediate-range ballistic missile program, and he developed the rockets that launched the United States' first space satellite Explorer 1.
  In 1960, his group was assimilated into NASA, where he served as director of the newly formed Marshall Space Flight Center and as the chief architect of the Saturn V super heavy-lift launch vehicle that propelled the Apollo spacecraft to the Moon. In 1967, von Braun was inducted into the National Academy of Engineering, and in 1975, he received the National Medal of Science.
context_section_description: Repeating the pattern he had established during his earlier career in Germany, von Braun – while directing military rocket development in the real world – continued to entertain his engineer-scientist's dream of a future in which rockets would be used for space exploration. However, he was no longer at risk of being sacked – as American public opinion of Germans began to recover, von Braun found himself increasingly in a position to popularize his ideas. The May 14, 1950, headline of The Huntsville Times ("Dr. von Braun Says Rocket Flights Possible to Moon") might have marked the beginning of these efforts. Von Braun's ideas rode a publicity wave that was created by science fiction movies and stories.
  In 1952, von Braun first published his concept of a crewed space station in a Collier's Weekly magazine series of articles titled "Man Will Conquer Space Soon!". These articles were illustrated by the space artist Chesley Bonestell and were influential in spreading his ideas. Frequently, von Braun worked with fellow German-born space advocate and science writer Willy Ley to publish his concepts, which, unsurprisingly, were heavy on the engineering side and anticipated many technical aspects of space flight that later became reality.
  The space station (to be constructed using rockets with recoverable and reusable ascent stages) would be a toroid structure, with a diameter of 250 feet (76 m); this built on the concept of a rotating wheel-shaped station introduced in 1929 by Herman Potočnik in his book The Problem of Space Travel – The Rocket Motor. The space station would spin around a central docking nave to provide artificial gravity, and would be assembled in a 1,075-mile (1,730 km) two-hour, high-inclination Earth orbit allowing observation of essentially every point on Earth on at least a daily basis. The ultimate purpose of the space station would be to provide an assembly platform for crewed lunar expeditions. More than a decade later, the movie version of 2001: A Space Odyssey would draw heavily on the design concept in its visualization of an orbital space station.
  Von Braun envisioned these expeditions as very large-scale undertakings, with a total of 50 astronauts traveling in three huge spacecraft (two for crew, one primarily for cargo), each 49 m (160.76 ft) long and 33 m (108.27 ft) in diameter and driven by a rectangular array of 30 rocket propulsion engines. Upon arrival, astronauts would establish a permanent lunar base in the Sinus Roris region by using the emptied cargo holds of their craft as shelters, and would explore their surroundings for eight weeks. This would include a 400 km (249 mi) expedition in pressurized rovers to the crater Harpalus and the Mare Imbrium foothills.
  At this time, von Braun also worked out preliminary concepts for a human mission to Mars that used the space station as a staging point. His initial plans, published in The Mars Project (1952), had envisaged a fleet of 10 spacecraft (each with a mass of 3,720 metric tonnes), three of them uncrewed and each carrying one 200-tonne winged lander in addition to cargo, and nine crew vehicles transporting a total of 70 astronauts. The engineering and astronautical parameters of this gigantic mission were thoroughly calculated. A later project was much more modest, using only one purely orbital cargo ship and one crewed craft. In each case, the expedition would use minimum-energy Hohmann transfer orbits for its trips to Mars and back to Earth.
  Before technically formalizing his thoughts on human spaceflight to Mars, von Braun had written a science fiction novel on the subject, set in the year 1980. However, the manuscript was rejected by no fewer than 18 publishers. Von Braun later published small portions of this opus in magazines, to illustrate selected aspects of his Mars project popularizations. The complete manuscript, titled Project MARS: A Technical Tale, did not appear as a printed book until December 2006.
  In the hope that its involvement would bring about greater public interest in the future of the space program, von Braun also
