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 used 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, 18 publishers rejected the manuscript. 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 began working with Walt Disney and the Disney studios as a technical director, initially for three television films about space exploration. The initial broadcast devoted to space exploration was Man in Space, which first went on air on 9 March 1955, drawing 40 million viewers. Later (in 1959) von Braun published a short booklet, condensed from episodes that had appeared in This Week Magazine before – describing his updated concept of the first crewed lunar landing. The scenario included only a single and relatively small spacecraft – a winged lander with a crew of only two experienced pilots who had already circumnavigated the Moon on an earlier mission. The brute-force direct ascent flight schedule used a rocket design with five sequential stages, loosely based on the Nova designs that were under discussion at this time. After a night launch from a Pacific island, the first three stages brought the spacecraft (with the two remaining upper stages attached) to terrestrial escape velocity, with each burn creating an acceleration of 8–9 times standard gravity. The residual propellant in the third stage was used for the deceleration intended to commence only a few hundred kilometers above the landing site in a crater near the lunar north pole. The fourth stage provided acceleration to lunar escape velocity, and the fifth stage was responsible for a deceleration during return to the Earth to a residual speed that allows aerocapture of the spacecraft ending in a runway landing, much in the way of the Space Shuttle. One remarkable feature of this technical tale is that the engineer von Braun anticipated a medical phenomenon that became apparent only years later: being a veteran astronaut with no history of serious adverse reactions to weightlessness offers no protection against becoming unexpectedly and violently spacesick.
=== Religious conversion === In the first half of his life, von Braun was a nonpracticing, perfunctory Lutheran. As described by Ernst Stuhlinger and Frederick I. Ordway III: "Throughout his younger years, von Braun did not show signs of religious devotion, or even an interest in things related to the church or to biblical teachings. In fact, he was known to his friends as a 'merry heathen' (fröhlicher Heide)." Nevertheless, in 1945 he explained his decision to surrender to the Western Allies, rather than Russians, as being influenced by a desire to share rocket technology with people whom he felt followed the Bible. In 1946, he attended church in El Paso, El Paso County, Texas, and underwent a religious conversion to Evangelical Christianity. In an unnamed religious magazine he stated:
One day in Fort Bliss, a neighbor called and asked if I would like to go to church with him. I accepted, because I wanted to see if the American church was just a country club as I'd been led to expect. Instead, I found a small, white frame building... in the hot Texas sun on a browned-grass lot... Together, these people make a live, vibrant community. This was the first time I really understood that religion was not a cathedral inherited from the past, or a quick prayer at the last minute. To be effective, a religion has to be backed up by discipline and effort. On the motives behind this conversion, Michael J. Neufeld is of the opinion that he turned to religion "to pacify his own conscience", and University of Southampton scholar Kendrick Oliver said that von Braun was presumably moved "by a desire to find a new direction for his life after the moral chaos of his service for the Third Reich". Having "concluded one bad bargain with the Devil, perhaps now he felt a need to have God securely at his side". At a Gideons conference in 2004, W. Albert Wilson, a former pilot and NASA employee, stated that he had talked with von Braun about the Christian faith while von Braun was working for NASA, and believed that conversation had been instrumental in von Braun's conversion. Later in life, he joined an Episcopal congregation, and became increasingly religious. He publicly spoke and wrote about the complementarity of science and religion, the afterlife of the soul, and his belief in God. He stated, "Through science man strives to learn more of the mysteries of creation. Through religion he seeks to know the Creator." He was interviewed by the Assemblies of God pastor C. M. Ward and stated that "The farther we probe into space, the greater my faith." In addition, he met privately with evangelist Billy Graham and with the civil rights leader Martin Luther King Jr.
