island, the first three stages would bring 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. Residual propellant in the third stage would be 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, while the fifth stage would be 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 would become 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, whose affiliation was nominal and not taken seriously. 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 who 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: On the motives behind this conversion, Michael J. Neufeld is of the opinion that he turned to religion "to pacify his own conscience", whereas 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, claimed that he had talked with von Braun about the Christian faith while von Braun
