Part I(chapters 1 to 5) traces theorigins of the Skylab concept from its emergence in theperiod 1962-65 through its evolutioninto final form in 1969. Part II(chapters 6 to 13) focuses on theperiod from 1969-73, considering thedevelopment of the spacecraftmodules, the experiments theycarried, and the preparations to launchand operate them. Chapter 6focuses on the program leader:', theproblems they faced, and the tools theyused to manage Skylab. Chapters7 through 11 deal with the majorexperimental programs and the spacecraft components. Houston'spreparations for directing the missions and the launching of Skylab aretreated in chapters 12 and 13 respectively. Part III(chapters 14 to 19) deals with theSkylab launch accident (the meteoroidshield ripped away, leaving the workshop exposed to solar heat anddisabling its solar panels), Skylab missions, program results(including medical andsolar/earth observation findings), and the endof Skylab. A summary ofmissions, list of major contractors, list ofexperiments, and additional documentation are included inappendices.

David Compton and Charles D. Benson The NASA History Series Scientific and Technical Information Branch ;983 National Aeronautics and Space Administration Washington, DC 6 NASA maintains an internal history program for two principal reasons. (1) Publication of official histories is one way in which NASA responds to the provision of the National Aeronautics and Space Act of 1958 that requires NASA to "provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." (2) Thoughtful study of NASA history can help managers accom- plish the missions assigned to the agency. Understanding NASA's past aids in under- standing its present situation and illuminates possible future directions. One advantage of working on contemporary history is access to participants. During the research phase, the authors conducted numerous interviews. Subsequently they submit- ted parts of the manuscript to persons who had participated in or closely observed the events described. Readers were asked to point out errors of fact and questionable inter- pretations and to provide supporting evidence. The authors then made such changes as they believed justified. The opinions and conclusions set forth in this book are those of the authors; no official of the agency necessarily endorses those opinions or conclusions.
