SEARS2 1Education Department, University of Alabama in Huntsville, Huntsville, Alabama, USA 2History Department, University of Alabama in Huntsville, Huntsville, Alabama, USA Set during the Cold War and space race, this historical role-play focuses on Wernher von Braun’s involvement in and culpability for the use of slave laborers to produce V-2 rockets for Nazi Germany. Students will grapple with two central questions. Should von Braun have been allowed to emigrate to the United States given his affiliation with the Nazis and use of slave laborers? Should the U.S. government and military have put Braun in powerful positions in NASA and military programs? This activity encourages students to hone their critical thinking skills as they consider and debate a complex, multi-layered historical scenario. Students also have opportunity to articulate persuasive arguments either for or against von Braun. Each character sketch includes basic information, but additional references are included for teachers and students who want a more in depth background.

  • How Doc Draper Became the Father of Inertial Guidance
    (Preprint) AAS 18-121 HOW DOC DRAPER BECAME THE FATHER OF INERTIAL GUIDANCE Philip D. Hattis* With Missouri roots, a Stanford Psychology degree, and a variety of MIT de- grees, Charles Stark “Doc” Draper formulated the basis for reliable and accurate gyro-based sensing technology that enabled the first and many subsequent iner- tial navigation systems. Working with colleagues and students, he created an Instrumentation Laboratory that developed bombsights that changed the balance of World War II in the Pacific. His engineering teams then went on to develop ever smaller and more accurate inertial navigation for aircraft, submarines, stra- tegic missiles, and spaceflight. The resulting inertial navigation systems enable national security, took humans to the Moon, and continue to find new applica- tions. This paper discusses the history of Draper’s path to becoming known as the “Father of Inertial Guidance.” FROM DRAPER’S MISSOURI ROOTS TO MIT ENGINEERING Charles Stark Draper was born in 1901 in Windsor Missouri. His father was a dentist and his mother (nee Stark) was a school teacher. The Stark family developed the Stark apple that was popular in the Midwest and raised the family to prominence1 including a cousin, Lloyd Stark, who became governor of Missouri in 1937. Draper was known to his family and friends as Stark (Figure 1), and later in life was known by colleagues as Doc. During his teenage years, Draper enjoyed tinkering with automobiles. He also worked as an electric linesman (Figure 2), and at age 15 began a liberal arts education at the University of Mis- souri in Rolla.

  • Chapter 6.Qxd
    CHAPTER 6: The NASA Family The melding of all of the NASA centers, contractors, universities, and often strong personalities associated with each of them into the productive and efficient organization necessary to complete NASA’s space missions became both more critical and more difficult as NASA turned its attention from Gemini to Apollo. The approach and style and, indeed, the personality of each NASA center differed sharply. The Manned Spacecraft Center was distinctive among all the rest. Fortune magazine suggested in 1967 that the scale of NASA’s operation required a whole new approach and style of management: “To master such massively complex and expensive problems, the agency has mobilized some 20,000 individual firms, more than 400,000 workers, and 200 colleges and universities in a combine of the most advanced resources of American civilization.” The author referred to some of the eight NASA centers and assorted field installations as “pockets of sovereignty” which exercised an enormous degree of independence and autonomy.1 An enduring part of the management problem throughout the Mercury and Gemini programs that became compounded under Apollo, because of its greater technical challenges, was the diversity and distinctiveness of each of the NASA centers. The diverse cultures and capabilities represented by each of the centers were at once the space program’s greatest resource and its Achilles’ heel. NASA was a hybrid organization. At its heart was Langley Memorial Aeronautical Laboratory established by Congress in 1917 near Hampton, Virginia, and formally dedicated in 1920. It became the Langley Research Center. Langley created the Ames Aeronautical Laboratory at Moffett Field, California, in 1939.

  • PEENEMUENDE, NATIONAL SOCIALISM, and the V-2 MISSILE, 1924-1945 Michael
    ABSTRACT Title of Dissertation: ENGINEERING CONSENT: PEENEMUENDE, NATIONAL SOCIALISM, AND THE V-2 MISSILE, 1924-1945 Michael Brian Petersen, Doctor of Philosophy, 2005 Dissertation Directed By: Professor Jeffrey Herf Departmen t of History This dissertation is the story of the German scientists and engineers who developed, tested, and produced the V-2 missile, the world’s first liquid -fueled ballistic missile. It examines the social, political, and cultural roots of the prog ram in the Weimar Republic, the professional world of the Peenemünde missile base, and the results of the specialists’ decision to use concentration camp slave labor to produce the missile. Previous studies of this subject have been the domain of either of sensationalistic journalists or the unabashed admirers of the German missile pioneers. Only rarely have historians ventured into this area of inquiry, fruitfully examining the history of the German missile program from the top down while noting its admi nistrative battles and technical development. However, this work has been done at the expense of a detailed examination of the mid and lower -level employees who formed the backbone of the research and production effort. This work addresses that shortcomi ng by investigating the daily lives of these employees and the social, cultural, and political environment in which they existed. It focuses on the key questions of dedication, motivation, and criminality in the Nazi regime by asking “How did Nazi authori ties in charge of the missile program enlist the support of their employees in their effort?” “How did their work translate into political consent for the regime?” “How did these employees come to view slave labor as a viable option for completing their work?” This study is informed by traditions in European intellectual and social history while borrowing from different methods of sociology and anthropology.

    P-357 THE HISTORY OF APOLLO ON-BOARD GUIDANCE, NAVIGATION, AND CONTROL by David G. Hoag September 1976 The Charles Stark Draper Laboratory, Inc. Cambridge, Massachusetts 02139 @ The Charles Stark Draper Laboratory, Inc. , 1976. the solar pressure force on adjustable sun vanes to drive the average speed of these wheels toward zero. Overall autonomous operation was managed on-board by a small general purpose digital computer configured by its designer, Dr. Raymond Alonso, for very low power drain except at the occasional times needing fast computation speed. A special feature of this computer was the pre-wired, read-only memory called a core rope, a configuration of particularly high storage density requiring only one magnetic core per word of memory. A four volume report of this work was published in July, 1959, and presented to the Air Force Sponsors. However, since the Air Force was disengaging from civilian space development, endeavors to interest NASA were undertaken. Dr. H. Guyford Stever, then an MIT professor, arranged a presentation with Dr. Hugh Dryden, NASA Deputy Administrator, which took place on September 15.* On November 10, NASA sent a letter of in- tent to contract the Instrumentation Laboratory for a $50,000 study to start immediately. The stated purpose was that this study would con- c tribute to the efforts of NASA's Jet Propulsion Laboratory in conducting unmanned space missions to Mars, Venus, and the Earth's moon scheduled in Vega and Centaur missions in the next few years. A relationship be- tween MIT and JPL did not evolve. JPL's approach to these deep space missions involved close ground base control with their large antenna tracking and telemetry systems, considerably different from the on- board self sufficiency method which the MIT group advocated and could best support.

  • The Following Are Edited Excerpts from Two Interviews Conducted with Dr
    Interviews with Dr. Wernher von Braun Editor's note: The following are edited excerpts from two interviews conducted with Dr. Wernher von Braun. Interview #1 was conducted on August 25, 1970, by Robert Sherrod while Dr. von Braun was deputy associate administrator for planning at NASA Headquarters. Interview #2 was conducted on November 17, 1971, by Roger Bilstein and John Beltz. These interviews are among those published in Before This Decade is Out: Personal Reflections on the Apollo Program, (SP-4223, 1999) edited by Glen E. Swanson, whick is vailable on-line at http://history.nasa.gov/SP-4223/sp4223.htm on the Web. Interview #1 In the Apollo Spacecraft Chronology, you are quoted as saying "It is true that for a long time we were not in favor of lunar orbit rendezvous. We favored Earth orbit rendezvous." Well, actually even that is not quite correct, because at the outset we just didn't know which route [for Apollo to travel to the Moon] was the most promising. We made an agreement with Houston that we at Marshall would concentrate on the study of Earth orbit rendezvous, but that did not mean we wanted to sell it as our preferred scheme. We weren't ready to vote for it yet; our study was meant to merely identify the problems involved. The agreement also said that Houston would concentrate on studying the lunar rendezvous mode. Only after both groups had done their homework would we compare notes. This agreement was based on common sense. You don't start selling your scheme until you are convinced that it is superior.

  • Supplementary Figure 1: Interconnected Multiplex with Six Nodes in Two Layers (A and D) and Corresponding Aggregated Networks (B and E)
    Supplementary Figure 1: Interconnected multiplex with six nodes in two layers (A and D) and corresponding aggregated networks (B and E). The nodes are ranked by their eigenvector centrality in each layer separately, in the aggregated and in the whole interconnected structure (C and F). Case A, B and C. Nodes 1 and 3 have a key role in the multilayer, being bridges between the two layers. In a collaboration network they would represent scientists working on two different research areas who allow information to flow from one subject to the other. While nodes 1 and 3 gain centrality from their connections to \hubs" on different layers, they also gain centrality from their own counterparts in other layers, making them important in the multilayer network. In the aggregated network their versatility disappears, because the information is washed out by projecting on a single layer, where nodes 2 and 6 are still \hubs" but it is not possible to capture the importance of nodes 1 and 3 in bridging different areas. Case D, E and F. This example shows how aggregating the full information on a single network introduces a spurious symmetry between nodes 2, 3, 4 and 6 that is not present in the multilayer, except for 2 and 4. The resulting score in the aggregate is not able to capture the difference between these nodes (corresponding to a degeneration in the eigenspace) while it is evident that, for instance, node 6 is more central than node 3 because of its direct connection to node 1 { the \hub" { in layer 1.

OUP UNCORRECTED PROOF – FIRST PROOF, 3/8/2018, SPi Preface As the field of complex networks entered its maturity phase, most scientists working in this field thought that the established methodology could deal with all casesof networked systems. However, as is usually the case in the scientific enterprise, some novel observations showed that what we already know is only a limited case, and network theory has still long way to go until we can make any definitive claim. The ever-increasing availability of data in fields ranging from computer science to urban systems, medicine, economics, and finance showed that networks that were usually perceived as distinct and isolated are, in reality, interacting with other networks. While this sounds like a trivial observation, it was shown that interactions of different networks can lead to unexpected behaviors and allow systemic vulnerabilities to emerge.
