These conferences have brought together engineers and scientists of diverse disciplines with the common interests of space simulation, its applications and solutions of complex problems that are encountered. This conference was favored with a wide variety of papers concerning facilities, testing and contamination control. Our featured speaker was Francis J. Logan, Deputy Project Manager, Solar Maximum Repair Mission, who spoke of the problems and successes of retrieving and repairing an orbiting spacecraft utilizing the Shuttle. This endeavor was a historic first for the space program. The meeting was concluded with a trip to the Kennedy Space Center to see the Shuttle complex and other points of interest. I wish to acknowledge the splendid effort of the many people who made this meeting successful. Robert P. Parrish, Jr., Martin Marietta Corp., Technical Program Chairman and his committee gave us a well rounded, informative program; Joseph L. Stecher, NASA GSFC, as Publications Chairman assembled these proceedings; John D. Campbell, Perkin Elmer Corp., was extremely helpful in his capacity as the IES Meeting Manager; and Betty Peterson, IES Executive Director, and Janet A. Ehman, IES Deputy Executive Director, did their usual excellent efforts in all administrative areas. R. T.
