The Skylab results; Proceedings of the Twentieth Annual Meeting, University of Southern California, Los Angeles, Calif., August 20-22, 1974. Parts 1 & 2

A comprehensive series of papers on the Skylab program, covering integration and testing, operations support, living and working in space, Skylab technology, the role of the Kennedy Space Center in Skylab, the Earth Resources Experiment Package (EREP), the student science program, Apollo Telescope Mount experiments, corollary experiments, and life-sciences data. The topics include: Skylab contamination control; management and control of the missions; extravehicular activity; the repair of major systems elements on Skylab; crew motion disturbances; the design and operation of the Skylab attitude and pointing control system; the performance of solar shields; Comet Kohoutek observations from Skylab; the Skylab food system; and an evaluation of life in Skylab from a medical viewpoint. Individual items are announced in this issue.

The influence of man in space observations

The paper evaluates the Skylab missions from the viewpoint of to what extent the presence of men may have been a detriment to scientific observations, either through their movements or through contamination of the spacecraft and instruments. The stability of the instrument canister within the Apollo Telescope Mount was secured by the Experiment Pointing Control System. Angular stability was specified to be within plus or minus 2.5 arc seconds, and was found to be less than 2 arc seconds during normal crew activity. No astronomical observations were reported as being degraded by crew movements. Instrumentation was installed to measure rates of contaminant particle deposition on optical surfaces. Clouds were formed from particles originating in outgassing from vehicle surface materials and from vent apertures. The Coronograph Contamination Measurement Instrument was used to measure the brightness of the induced cloud surrounding Skylab. Preliminary analysis shows no significant degradation of photographic data attributable to contamination.

Operational aspects of Skylab

Attention is given to the salient features of Skylab design and the development process in order to illustrate how they influenced the flight operations. Organizational questions are considered, giving attention to the functions of the flight management team, the conduction of the flight operations by the Mission Operations Team, details regarding the engineering support organization, and aspects of science support.
