Access to Space Beyond the Year 2000
by Delma C. Freeman, Jr.
Tuesday, January 13, 1998 at 2:00 p.m. in the H.J.E. Reid Auditorium.
Access to space began with the successful launch of the Sputnik 1 satellite October 4, 1957. Thus began a race to space that has spanned forty years and resulted in spectacular achievements in communication, human presence in space and it’s exploration, research in space and earth sciences, and a multitude of spin offs that have positively affected virtually everyone on earth. Governments have been the primary sponsors of access to space. Today, this paradigm is shifting. There are numerous endeavors around the world to commercially produce expendable vehicle systems to launch small and medium payloads into earth orbit. The National Aeronautics and Space Administration is facilitating an industry developed commercial reusable launch system. This system, called the Reusable Launch Vehicle (RLV) Program is an option to succeed the Space Shuttle and provide significantly reduced cost to access space in the 2000-2010 time frame.
This presentation focuses on the NASA Reusable Launch Vehicle Program. It will give an historic perspective on the analysis, the discussions, and the processes that lead to the decision to proceed with the RLV Program. The political, technical and administrative activity required to implement the Phase 1 Advanced Launch Technology Program, the Phase 2 X-33 Program, and the Phase 3 RLV Commercial Development Program will be presented. There will also be discussion on the impact of doing this program in the commercial market as opposed to a government program like the Shuttle.

How Aerospace Gets to Your Home
by Joseph S. Heyman
Tuesday, February 3, 1998 at 2:00 p.m. in the H.J.E. Reid Auditorium.
How does AeroSpace technology get to your home? Your car? Your medical caregiver? What does it do and who got it there? NASA’s Aeronautics and Space Programs reach far beyond their direct AeroSpace products. Many people know that America’s greatest contribution to the balance of foreign trade is the aviation industry. Over the past ten years, that industry brought over $20B to U.S. soil. It could be well over $40B for the next decade, with the next generation of advanced commercial and high speed transports! NASA enables many technologies, but, how does NASA touch the face of America in other ways?
NASA and NACA Programs contribute to the economic health of the United States. Recently, however, NASA took dramatic steps to accelerate its benefits to the American public. This talk will focus on how Intellectual Property (Patents) enables development of economic opportunities. Companies are licensing patents and building new futures. Methods of creating partnerships with industry will be discussed resulting in benefits to industry, to NASA and to the American public. Dr. Heymen will highlight new products for air quality, materials, sensors, and health.
Dr. Joseph S. Heyman is Director of the Technology Applications Group at the NASA Langley Research Center in Hampton, Virginia. He received many awards including NASA’s Exceptional Service Medal and NASA’s Outstanding Leadership Medal. Dr. Heyman is responsible for the Center’s technology partnership programs with industry to enhance America’s national competitiveness. This Group primarily provides leadership for the Small Business Innovation Research (SBIR) Programs, Space Act Agreements with non-aerospace industries, and licenses of NASA’s intellectual property. In addition, the Group facilitates all technology transfer agreements between the Research Center and industry.
NASA Research on the Russian Space Station
by Greg Stover
Tuesday, March 3, 1998 at 2:00 p.m. in the H.J.E. Reid Auditorium.
Between March 1995 and May 1998, the Russian Space Station Mir hosts NASA astronauts as crewmembers, and a variety of US experiments. The NASA program supporting this endeavor is commonly known as International Space Station (ISS) Phase 1. This program utilizes Mir to gain experience in the areas of cooperation, investigation, and operation in preparation for the construction and utilization of the International Space Station. ISS designers are using Mir as an unique opportunity for long-duration data gathering for space station hardware, materials, and construction methods. In addition, Mir crewmembers are taking advantage of the microgravity environment to conduct scientific investigations and make improvements in operational procedures. Mr. Stover will discuss LaRC’s involvement with the Phase I program and will present results gathered from experiments conducted on Mir. The experiments were conducted both internally and externally and involve crew force measurements, superconducting materials, debris and materials exposure, and Earth sensing instruments.
Greg Stover is the Deputy Manager of the LaRC CERES Project, a remote sensing instrument recently launched on the TRMM observatory and scheduled for future flight on the EOS AM and PM missions. He previously served as Project Manager for MEEP, a debris and materials exposure experiment which successfully flew on Mir for 18 months, and for MACE, a structural dynamics and controls experiment which successfully flew on STS-67. Mr. Stover, a native of Jasper, Alabama, joined NASA in 1990 as an electrical engineer specializing in control systems. He has a B.S. from Auburn University, a M.S. and his Ph.D. coursework in Electrical Engineering from the Georgia Institute of Technology.
Designing the Mind-Centered Flight Deck
by Paul Schutte and Alan Pope
Tuesday, April 7, 1998 at 2:00 p.m. in the H.J.E. Reid Auditorium.
NASA has embarked on a bold new program to significantly reduce the number of aviation accidents world-wide. Over 70% of all aviation accidents and incidents have been attributed to human error. A group of researchers at NASA Langley believe that if flight decks were designed to take into account human limitations and to take advantage of uniquely human capabilities, a large number of these accidents could be averted. This group is working on a project called “Error Proof Flight Deck” which seeks to design a flight deck so that normal, fallible human behavior will not jeopardize the safety and efficiency of a flight mission. The design seeks not only to reduce the negative consequences of human behavior, but also to allow the mission to benefit from uniquely human abilities such as creativity, intuition, innovation, ingenuity, and responsibility – abilities that computers and automation do not yet have. The group believes that while human error has contributed to a large number of accidents, these uniquely human capabilities have prevented an even larger number of accidents. This colloquium will discuss how this group is using advanced measurement technologies Mapping), mental models, and innovative interface techniques and concepts to design a flight deck that reinforces the mental capabilities of the crew. In addition it will describe how spin-offs from these efforts are contributing technologies for mind-body medicine. The colloquium will be presented jointly by Mr. Schutte and Dr. Pope, and will include a demonstration of some of the measurement techniques.
Paul C. Schutte is a research scientist and technical team leader in the Flight Dynamics and Control Division, NASA Langley Research Center where he has worked since 1981. He has conducted research in knowledge-based systems for onboard aiding of civil transport flight crews, particularly in subsystem fault management. He codeveloped the Faultfinder fault management concept which received the 1991 R+D 100 award. He is the technical leader of the Error Proof Flight Deck team investigating human centered design concepts for civil aviation flight decks. His particular research interests include fault management and human-machine interaction. Mr. Schutte graduated from Mary Washington College with a B.S. in Mathematics and Physics and from the College of William and Mary with a M.S. in Computer Science.
Alan T. Pope is a research scientist in the Flight Dynamics and Controls Division, NASA Langley Research Center where he has worked since 1980. He leads the Hazards and Error Management (HEM) research program. The HEM program is engaged in the research and development of methods for identifying and controlling factors that lead a flight crew to error. He is also a Licensed Clinical Psychologist, Assistant Professor at the Eastern Virginia Medical School, and Senior Lecturer at Christopher Newport University. Dr. Pope received a B.S. and a M.S. in Electrical Engineering, respectively, from Tennessee Technological University and the University of Tennessee. He graduated from the University of Florida with a Ph.D. in Clinical Psychology. Dr. Pope is the 1998 recipient of the AIAA Contribution to Society Award for his work on technologies for attention deficit disorder, diabetes, and stress-related disorders.
Innumeracy, Newspapers, and Democracy
by John Allen Paulos
Tuesday, May 5, 1998 at 2:00 p.m. in the H.J.E. Reid Auditorium.
The talk will reprise some of the issues discussed in Innumeracy and, especially, in A Mathematician Reads the Newspaper. Structured like the morning paper, the latter book investigates the mathematical angles of stories in the news. Mathematical naivete can put such readers at a disadvantage in thinking about many issues in the news that may seem on the surface not to involve mathematics at all. “Number stories” complement, deepen, and regularly undermine “people stories.” The notions of probability and randomness can enhance articles on crime, health risks, or other societal obsessions (including the bible codes). Logic and self-reference may help to clarify the hazards of celebrity and spin-doctoring. Business finance, the multiplication principle, and simple arithmetic point up consumer fallacies, electoral tricks, and sports myths. Chaos and non-linear dynamics suggest how difficult and frequently worthless economic and environmental prediction is. And mathematically pertinent notions from philosophy and psychology provide perspective on a variety of contemporary public issues.
Bestselling author, mathematician, and public speaker, John Allen Paulos received his Ph.D. in mathematics from the University of Wisconsin. Now a professor of mathematics at Temple University in Philadelphia, he is married and the father of two children. In addition to being the author of a number of scholarly papers on mathematical logic, probability, and the philosophy of science, Dr. Paulos has written Mathematics and Humor (1980), I Think, Therefore I Laugh (1985), Innumeracy – Mathematical Illiteracy and Its Consequences (1989), Beyond Numeracy – Ruminations of a Numbers Man (1991), and A Mathematician Reads the Newspaper (1995). An active public speaker whose talks are both illuminating and humorous, he has spoken to audiences from the Smithsonian to Harvard’s Nieman Fellows, from the National Academy of Sciences to local colleges, and from library and mathematics associations to business and financial forums.
The Human Adventure Continues
by William L. Smith
Tuesday, June 2, 1998 at 2:00 p.m. in the H.J.E. Reid Auditorium.
The Human Exploration and Development of Space (HEDS) is the NASA Enterprise whose mission is to open the space frontier by exploring, using, and enabling the development of space and to expand the human experience into the far reaches of space. HEDS seeks the marriage of robotic and human capabilities to overcome the challenges of distance, time, and environment. The HEDS goals include preparing to conduct human missions of exploration to planetary and other bodies in the solar system; Use the environment of space to expand scientific knowledge; provide for safe and affordable human access to space , establish a human presence in space, and share the human experience of being in space; and enable the commercial development of space and share HEDS knowledge, technologies and assets that promise to enhance the quality of life on Earth.
The Space Shuttle and the International Space Station serve as research platforms to pave the way for sustained human presence in space through critical research on human adaptation. Lessons learned in operation and research utilizing these system capabilities represent stepping stones human exploration for return to the Moon or Martian missions. This presentation will focus on the conduct of Mars Human Exploration mission from launch to return of the explorers.
William L. Smith, Deputy Director of Space and Atmospheric Sciences Programs Group of the NASA Langley Research Center, started his NASA career in 1965 in the then named Office of Advanced Research and Technology at NASA Headquarters.

Status Report on Project Phoenix – A Privately Funded Search for Extraterrestrial Intelligence
by Jill Tarter
Tuesday, November 3, 1998 at 2:00 p.m. in the H.J.E. Reid Auditorium.
Since 1995, Project Phoenix has been using pairs of large radio telescopes around the world to conduct comprehensive searches for evidence of signals from other technological civilizations. We have now examined about half our initial list of target stars with a sensitivity adequate to detect signals as strong as our terrestrial radars (10^12 W EIRP) coming from the most distant targets (155 light years). Results to date are negative. We have just embarked on a five year observing program utilizing Arecibo Observatory and the Lovell Telescope at Jodrell Bank, which enables even greater sensitivity.
We are also conducting a series of internal workshops designed to provide guidance for the next few decades. In the near future, we shall be building new signal detection systems at a number of wavelengths and constructing novel new arrays of antennas to permit continuous observing. One of these arrays will also serve as a prototype to demonstrate the breakthrough technologies necessary to construct a collaborative, international astronomical array with extremely wide bandwidth and 10^6 square meters of collecting area, at an affordable cost. Such an instrument could simultaneously conduct SETI, radio astronomy, and spacecraft tracking. We are beginning to bet on Moore’s Law (i.e., that the power of computer processors will roughly double every 18 months). This talk will explain what we’ve done, and how we are planning for future success.
Dr. Tarter is an astronomer and one of the world’s leading researchers in the search for extraterrestrial intelligence (SETI). She is a founder of the SETI Institute in Mountain View, California, where she is the Director of Project Phoenix, a privately funded search for extraterrestrial life using radio telescopes. Dr. Tarter received a Bachelor of Engineering Physics with Distinction from Cornell University, and a Master’s Degree and Ph. D. in Astronomy from the University of California at Berkeley. Her major field of study was theoretical high energy physics. She was a NRC Postdoctoral Fellow at the NASA Ames Research Center. She has made major scientific advances in astronomy, including her pioneering research on so-called “brown” dwarf stars.
Dr. Tarter recalls that for many years while filling out forms that asked for her mother’s occupation, her young daughter would write “looks for little green men.” Dr. Tarter was a long-time colleague and close friend of the late Carl Sagan, author of the novel and movie, “Contact,” and many believe that she was the real-life inspiration for the story’s lead character, radio astronomer Ellie Arroway, played by actress Jodie Foster. For her pioneering research in SETI, Dr. Tarter has received two NASA Public Service Awards.
