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. Concepts for orbital warfare Von Braun developed and published his space station concept during the time of the Cold War when the U.S. government put the containment of the Soviet Union above everything else. The fact that his space station – if armed with missiles that could be easily adapted from those already available at this time – would give the United States space superiority in both orbital and orbit-to-ground warfare did not escape him. In his popular writings, von Braun elaborated on them in several of his books and articles, but he took care to qualify such military applications as "particularly dreadful". This much-less-peaceful aspect of von Braun's "drive for space" has been reviewed by Michael J. Neufeld from the Space History Division of the National Air and Space Museum in Washington. NASA career The U.S. Navy had been tasked with building a rocket to lift satellites into orbit, but the resulting Vanguard rocket launch system was unreliable. In 1957, with the launch of Sputnik 1, a belief grew within the United States that it lagged behind the Soviet Union in the emerging Space Race. American authorities then chose to use von Braun and his German team's experience with missiles to create an orbital launch vehicle. Von Braun had originally proposed such an idea in 1954, but it was denied at the time. NASA was established by law on 29 July 1958. One day later, the 50th Redstone rocket was successfully launched from Johnston Atoll in the south Pacific as part of Operation Hardtack I. Two years later, NASA opened the Marshall Space Flight Center at Redstone Arsenal in Huntsville, and the Army Ballistic Missile Agency (ABMA) development team led by von Braun was
