Space Environment – Implications for Spacecraft DesignCourse # P233SummaryAdverse interactions between the space environmentand an orbiting spacecraft may lead to a degradation ofspacecraft subsystem performance and possibly evenloss of the spacecraft itself. This two-day course presentsan introduction to the space environment and its effect onspacecraft. Emphasis is placed on problem solvingtechniques and design guidelines that will provide thestudent with an understanding of how space environmenteffects may be minimized through proactive spacecraftdesign.Each student will receive a copy of the course text, acomplete set of course notes, including copies of allviewgraphs used in the presentation, and acomprehensive bibliography.“I got exactly what I wanted from thiscourse – an overview of the spacecraft environment.The charts outlining the interactionsand synergism were excellent. Thelist of references is extensive and will beconsulted often.”“Broad experience over many designteams allowed for excellent examples ofapplications of this information.”InstructorDr. Alan C. Tribble has provided space environments effectsanalysis to more than one dozen NASA, DoD,and commercial programs, including theInternational Space Station, the GlobalPositioning System (GPS) satellites, andseveral surveillance spacecraft. He holds aPh.D. in Physics from the University of Iowaand has been twice a Principal Investigatorfor the NASA Space Environments andEffects Program. He is the author of four books, including thecourse text: The Space Environment - Implications for SpaceDesign, and over 20 additional technical publications. He is anAssociate Fellow of the AIAA, a Senior Member of the IEEE,and was previously an Associate Editor of the Journal ofSpacecraft and Rockets. Dr. Tribble recently won the 2008AIAA James A. Van Allen Space Environments Award. He hastaught a variety of classes at the University of SouthernCalifornia, California State University Long Beach, theUniversity of Iowa, and has been teaching courses on spaceenvironments and effects since 1992.Review of the Course Text:“There is, to my knowledge, no other book that provides itsintended readership with an comprehensive and authoritative,yet compact and accessible, coverage of the subject ofspacecraft environmental engineering.” – James A. Van Allen,Regent Distinguished Professor, University of Iowa.Who Should Attend:Engineers who need to know how to design systems withadequate performance margins, program managers whooversee spacecraft survivability tasks, and scientists whoneed to understand how environmental interactions can affectinstrument performance.February 3-5, 2015Columbia, Maryland$1295 (8:30am - 4:00pm)"Register 3 or More & Receive $100 00 eachOff The Course Tuition."Course Outline1.

Space Mission Structures: From Concept to LaunchCourse # P241Testimonial"Excellent presentation—a reminder ofhow much fun engineering can be."November 11-14, 2014Littleton, Colorado$2050 (8:30am - 5:00pm)"Register 3 or More & Receive $100 00 eachOff The Course Tuition."SummaryThis four-day short course presents a systemsperspective of structural engineering in the space industry.If you are an engineer involved in any aspect ofspacecraft or launch–vehicle structures, regardless ofyour level of experience, you will benefit from this course.Subjects include functions, requirements development,environments, structural mechanics, loads analysis,stress analysis, fracture mechanics, finite–elementmodeling, configuration, producibility, verificationplanning, quality assurance, testing, and risk assessment.The objectives are to give the big picture of space-missionstructures and improve your understanding of• Structural functions, requirements, and environments• How structures behave and how they fail• How to develop structures that are cost–effective anddependable for space missionsDespite its breadth, the course goes into great depth inkey areas, with emphasis on the things that are commonlymisunderstood and the types of things that go wrong in thedevelopment of flight hardware. The instructor sharesnumerous case histories and experiences to drive themain points home. Calculators are required to work classproblems.Each participant will receive a copy of the instructors’850-page reference book, Spacecraft Structures andMechanisms: From Concept to Launch.InstructorsTom Sarafin has worked full time in the space industrysince 1979, at Martin Marietta and InstarEngineering. Since founding InstarEngineering in 1993, he has consulted forDigitalGlobe, AeroAstro, AFRL, andDesign_Net Engineering. He has helpedthe U. S. Air Force Academy design,develop, and test a series of smallsatellites and has been an advisor to DARPA. He is theeditor and principal author of Spacecraft Structures andMechanisms: From Concept to Launch and is acontributing author to all three editions of Space MissionAnalysis and Design. Since 1995, he has taught over 200short courses to more than 4000 engineers and managersin the space industry.Poti Doukas worked at Lockheed Martin SpaceSystems Company (formerly MartinMarietta) from 1978 to 2006. He served asEngineering Manager for the Phoenix MarsLander program, Mechanical EngineeringLead for the Genesis mission, Structuresand Mechanisms Subsystem Lead for theStardust program, and Structural AnalysisLead for the Mars Global Surveyor. He’s a contributingauthor to Space Mission Analysis and Design (1st and 2ndeditions) and to Spacecraft Structures and Mechanisms:From Concept to Launch.Course Outline1.
