Because it is humanity’s destiny to strive, to seek, to find. And because it is America’s destiny to lead.” President George Bush, 20 July 19891 Sitting on the steps of the Smithsonian Institution’s National Air and Space Museum on 20 July 2004, it was difficult to imagine that fifteen years earlier at this place the fiercest domestic political conflict of the first space age commenced. Bright-eyed children poured off tour buses and hurried to examine the museum’s wonders, teachers and parents close behind with digital cameras ready. They lined up to touch a four billion year-old lunar rock, clamored around the Apollo 11 Com- mand Module Columbia, and gazed up at an ungainly Lunar Module— monuments to past American triumphs in space. It was on a similarly hot and muggy Washing- ton morning that President George Bush had used this location to announce a renewed commitment to human exploration beyond Earth orbit. Even before this declaration, however, the winds of war had been swirling in the nation’s capital. On the 20th anniversary of the first human landing on the Moon, President Bush had stood atop these very steps and proposed a long-range exploration plan that included the successful construction of an orbital space station, a permanent return to the Moon, and a human mission to Mars—this enterprise became known as the Space Exploration Initiative (SEI). The president charged the newly rees- tablished National Space Council with providing concrete alternatives for meeting these objectives. To provide overall focus for the new initiative, Bush later set a 30- year goal for a crewed landing on Mars. If met, humans would be walking on the red 1 Public Papers of the Presidents of the United States, 20 July 1989, Remarks on the 20th Anniversary of the Apollo 11 Moon Landing [http://bushlibrary.tamu.edu/papers/] (accessed 18 May 2002). 1 Mars Wars Chapter 1: Introduction planet by 2019, which would be the 50th anniversary of the Apollo 11 lunar land- the government agenda and what factors led to its ultimate demise.

  • PERFORMED IDENTITIES: HEAVY METAL MUSICIANS BETWEEN 1984 and 1991 Bradley C. Klypchak a Dissertation Submitted to the Graduate
    PERFORMED IDENTITIES: HEAVY METAL MUSICIANS BETWEEN 1984 AND 1991 Bradley C. Klypchak A Dissertation Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY May 2007 Committee: Dr. Jeffrey A. Brown, Advisor Dr. John Makay Graduate Faculty Representative Dr. Ron E. Shields Dr. Don McQuarie © 2007 Bradley C. Klypchak All Rights Reserved iii ABSTRACT Dr. Jeffrey A. Brown, Advisor Between 1984 and 1991, heavy metal became one of the most publicly popular and commercially successful rock music subgenres. The focus of this dissertation is to explore the following research questions: How did the subculture of heavy metal music between 1984 and 1991 evolve and what meanings can be derived from this ongoing process? How did the contextual circumstances surrounding heavy metal music during this period impact the performative choices exhibited by artists, and from a position of retrospection, what lasting significance does this particular era of heavy metal merit today? A textual analysis of metal- related materials fostered the development of themes relating to the selective choices made and performances enacted by metal artists. These themes were then considered in terms of gender, sexuality, race, and age constructions as well as the ongoing negotiations of the metal artist within multiple performative realms. Occurring at the juncture of art and commerce, heavy metal music is a purposeful construction. Metal musicians made performative choices for serving particular aims, be it fame, wealth, or art. These same individuals worked within a greater system of influence. Metal bands were the contracted employees of record labels whose own corporate aims needed to be recognized.

After explosive throwing out as cone-like rocks they plastically evolved with density decays and materials transformations. Their expansion evolutions were accompanied by global ruptures and small scale rock ejections with concurrent crater formations. The scenario reconciles orbital and physical parameters of the moons. It coherently explains dozens of their properties including spectra, appearances, size differences, crater locations, fracture symmetries, orbits, evolution trends, geologic activity, Phobos’ grooves, mechanism of their origin, etc. The ejective approach is also discussed in the context of observational data on near-Earth asteroids, main belt asteroids Steins, Vesta, and Mars. The approach incorporates known fission mechanism of formation of miniature asteroids, logically accounts for its outliers, and naturally explains formations of small celestial bodies of various sizes.

  • Mars Scenario-Based Visioning: Logisitical Optimization of Transportation Architectures
    MARS SCENARIO-BASED VISIONING: LOGISITICAL OPTIMIZATION OF TRANSPORTATION ARCHITECTURES GEORGIA INSTITUTE OF TECHNOLOGY Contributors: Ashraf Charania Kris Cowart Brad St. Germain Tadashi Sakai Roberto Salinas Kirk Sorensen Jeffrey Tooley Shannan Wilson Advisor: Dr. John R. Olds Assistant Professor, School of Aerospace Engineering Director, Space Systems Design Lab (SSDL) Georgia Institute of Technology ABSTRACT The purpose of this conceptual design investigation is to examine transportation forecasts for future human missions to Mars. Scenario-Based Visioning is used to generate possible future demand projections. These scenarios are then coupled with availability, cost, and capacity parameters for indigenously designed Mars Transfer Vehicles (solar electric, nuclear thermal, and chemical propulsion types) and Earth-to-Orbit launch vehicles (current, future, and indigenous) to provide a cost-conscious dual-phase launch manifest to meet such future demand. A simulator named M-SAT (Mars Scenario Analysis Tool) is developed using this method. This simulation is used to examine three specific transportation scenarios to Mars: a limited "flags and footprints" mission, a more ambitious scientific expedition similar to an expanded version of the Design Reference Mission from NASA, and a long-term colonization scenario. Initial results from the simulation indicate that chemical propulsion systems might be the architecture of choice for all three scenarios. With this mind, "what if" analyses were performed which indicated that if nuclear production costs were reduced by 30% for the colonization scenario, then the nuclear architecture would have a lower life cycle cost than the chemical. Results indicate that the most cost-effective solution to the Mars transportation problem is to plan for segmented development, this involves development of one vehicle at one opportunity and derivatives of that vehicle at subsequent opportunities.

  • Mars, Phobos, and Deimos Sample Return Enabled by ARRM Alternative Trade Study Spacecraft
    Mars, Phobos, and Deimos Sample Return Enabled by ARRM Alternative Trade Study Spacecraft Jacob A. Englander,∗ Matthew A. Vavrina,† Bo Naasz ,‡ Raymond G. Merill,MinQu§ ¶ The Asteroid Robotic Redirect Mission (ARRM) has been the topic of many mission design studies since 2011.1 The reference ARRM spacecraft uses a powerful solar electric propulsion (SEP) system and a bag device to capture a small asteroid from an Earth-like orbit and redirect it to a distant retrograde orbit (DRO) around the moon. The ARRM Option B spacecraft uses the same propulsion system and multi-Degree of Freedom (DoF) manipulators device to retrieve a very large sample (thousands of kilograms) from a 100+ meter diameter farther-away Near Earth Asteroid (NEA). This study will demonstrate that the ARRM Option B spacecraft design can also be used to return samples from Mars and its moons - either by acquiring a large rock from the surface of Phobos or Deimos, and/or by rendezvousing with a sample-return spacecraft launched from the surface of Mars. I. Introduction The Asteroid Robotic Redirect Mission (ARRM) Option A concept, first introduced in 2011,1 is a mission design to capture and return a small near-Earth asteroid (NEA) to cislunar space. The ARRM Option B concept is a similar spacecraft, but designed to return a very large sample from a more difficult to reach NEA.2 In this work we show that the spacecraft designed for ARRM Option B is also well-suited to sample return from Mars and its moons. This work presents low-thrust interplanetary trajectories from cislunar space to Mars and back, including descent from the Martian sphere of influence (SOI) to the desired orbit altitude and ascent to the SOI after the sample retrieval is complete.
