Science Systems Engineering and Space Science

Talk Details:
Developing complex systems, whether they be scientific experiments on the ground or in space involves the efforts of many individuals and many science and engineering disciplines. Systems Engineering is a formalism designed to help keep track of these various facets of a project and to assure proper coordination and communication across disciplines and specialties. Subsystem systems engineers conduct trade studies to find optimal solutions to specific implementation needs and mission systems engineers coordinate these at a project level. Science Systems Engineering takes a broader view of complex systems by considering the problem that is being addressed, and the impact of implementation on the outcome as it relates to the problem. This is a more holistic perspective that has less formalism and process than traditional systems engineering. It is summarized by the "Method" - 1. Learn (know), 2. Think (analyze), 3. Plan (develop), 4. Do (proceed). I will review some of the basic principles of both systems and science systems engineering with some examples and stories.

About the Speaker:
Dr. Stephen S. Murray is a Research Professor at JHU in the Physics and Astronomy Department. He holds a joint appointment at the Space Telescope Science Institute and is also a Senior Astrophysicist at the Smithsonian Astrophysical Observatory in Cambridge MA. Dr. Murray did his graduate work at CalTech where he earned a PhD in Physics studying cosmic rays from the sun. He is the Principal Investigator for the High Resolution Camera on the Chandra X-ray Observatory, which was launched in 1999 and is now in its 14-th year of operation. He is also the PI for the NASA Astrophysics Data System, a complete on-line bibliographic reference system for astronomy and astrophysics literature.

Dr. Murray's research interests include X-ray astronomy, the study of clusters of galaxies, active galactic nuclei and their supermassive black holes, X-ray pulsars, and the structure and evolution of the universe. He is also working on new space missions ranging from an X-ray sky survey, to a study of the small bodies in the solar system in the Kuiper Belt and Oort Cloud, to a nano-satellite to characterize the diffuse X-ray emission coming from the local interstellar medium. Dr. Murray teaches the Introduction to Space Science and Technology course at JHU.
