Space Environment – Implications for Spacecraft Design
Adverse interactions between the space environment and an orbiting spacecraft may lead to a degradation of spacecraft subsystem performance and possibly even loss of the spacecraft itself. This two-day course presents an introduction to the space environment and its effect on spacecraft. Emphasis is placed on problem solving techniques and design guidelines that will provide the student with an understanding of how space environment effects may be minimized through proactive spacecraft design.
Each student will receive a copy of the The Space Environment: Implications for Spacecraft Design (Revised & Expanded), a complete set of course notes, including copies of all slides used in the presentation, and a comprehensive bibliography.
Who should attend:
Engineers who need to know how to design systems with adequate performance margins, program managers who oversee spacecraft survivability tasks, and scientists who need to understand how environmental interactions can affect instrument performance.

There is, to my knowledge, no other book that provides its intended readership with an comprehensive and authoritative, yet compact and accessible, coverage of the subject of spacecraft environmental engineering.

I got exactly what I wanted from this course – an overview of the spacecraft environment.The charts outlining the interactions and synergism were excellent.The list of references is extensive and will be consulted often.
Broad experience over many design teams allowed for excellent examples of applications of this information.

Dr. Alan C. Tribble has provided space environments effects analysis to more than one dozen NASA, DoD, and commercial programs, including the International Space Station, the Global Positioning System (GPS) satellites, and survival surveillance spacecraft. He holds a Ph.D. in Physics from the University of Iowa and has been twice a Principal Investigator for the NASA Space Environments and Effects Program. He is the author of four books, including the course text: The Space Environment – Implications for Space Design, and over 20 additional technical publications. He is an Associate Editor of the Journal of Spacecraft and Rockets, and Associate Fellow of the AIAA and a Senior Member of the IEEE. Dr. Tribble recently won the 2008 AIAA James A. Van Allen Space Environments Award. He has taught a variety of classes at the University of Southern California, California State University Long Beach, the University of Iowa, and has been teaching courses on space environments and effects since 1992.
